1.软嵌企业框架期中复习-SSM整合

============================

============================

前言

SSM劝退的90%理由就是配置太烦了,传说中的配置地狱。
那么这篇博文就是用了kari本人平时的开发习惯来配置的,做的一套SSM整合的增删改查。比如Kari平时用lombok来简化pojo编写,用c3p0数据库连接池。那这些都没有关系,同学们不用在乎这个,这些都只不过融入了下面的配置中。而且kari选择了maven项目,并且在maven中加入了阿里仓库的远程依赖,所以项目导入速度是比较快的。

我们不可能每次做项目都自己整合一次ssm,一般都用一个像这种以book数据表为基础的基础增删改查的基本项目,保存基本版本,以后每次做项目的时候复制这个基础项目,然后改代码就行了。比如这个项目里用的是book类,那下一次项目用user类的话就依葫芦画瓢改就行了。

建议先跟着本篇博文进行项目配置,如果实在不行就下载kari上传到百度网盘的成品

数据库环境

一次性插入可能存在问题,建议先创库,再创表,最后插入记录

CREATE DATABASE `ssmbuild`;

USE `ssmbuild`;

DROP TABLE IF EXISTS `books`;

CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(11) NOT NULL COMMENT '数量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8

INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');

基本环境搭建

1、新建一Maven项目（我起名ssmbuild）勾选webapp。添加web的支持

2、导入相关的pom依赖！（奖以下代码复制到pom.xml中）

<dependencies>
    <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->

        <scope>provided</scope>
    </dependency>

</dependencies>

3、Maven资源过滤设置

    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

4、建立基本结构和配置框架！

com.chk.pojo
com.chk.mapper
com.chk.service
com.chk.controller

image.png

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>
applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

Mybatis层编写

1、数据库配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

2、编写MyBatis的核心配置文件 mybatis-config.xml

<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <typeAliases>
        <package name="com.chk.pojo"/>
    </typeAliases>
    <mappers>
        <mapper resource="com/chk/mapper/BookMapper.xml"/>
    </mappers>
</configuration>

3、编写数据表对应的实体类 com.chk.pojo.Books

解释 :这里我写了
@AllArgsConstructor
@NoArgsConstructor
@Data
三个注解,这个是lombok的注解方法，写上这三个注解就不用再手动去生成有参无参构造包括get set。因为lombok已经帮我们生成了。那lombok需要下载吗？不用的,之前在pom.xml里已经加入了lombok的依赖了。

package com.chk.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@AllArgsConstructor
@NoArgsConstructor
@Data
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}

4、编写 Mapper层的 Mapper接口

BookMapper

package com.chk.mapper;

import com.chk.pojo.Books;
import java.util.List;

public interface BookMapper {
    //增加一个Book
    int addBook(Books book);

    //根据id删除一个Book
    int deleteBookById(int id);

    //更新Book
    int updateBook(Books books);

    //根据id查询,返回一个Book
    Books queryBookById(int id);

    //查询全部Book,返回list集合
    List<Books> queryAllBook();
}

5、编写接口对应的 Mapper.xml 文件。

BookMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.chk.mapper.BookMapper">

    <!--增加一个Book-->
    <insert id="addBook" parameterType="Books">
      insert into ssmbuild.books(bookName,bookCounts,detail)
      values (#{bookName}, #{bookCounts}, #{detail})
   </insert>

    <!--根据id删除一个Book-->
    <delete id="deleteBookById" parameterType="int">
      delete from ssmbuild.books where bookID=#{bookID}
   </delete>

    <!--更新Book-->
    <update id="updateBook" parameterType="Books">
      update ssmbuild.books
      set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
      where bookID = #{bookID}
   </update>

    <!--根据id查询,返回一个Book-->
    <select id="queryBookById" resultType="Books">
      select * from ssmbuild.books
      where bookID = #{bookID}
   </select>

    <!--查询全部Book-->
    <select id="queryAllBook" resultType="Books">
      SELECT * from ssmbuild.books
   </select>
</mapper>

6、编写Service层的接口和实现类

接口: BookService

package com.chk.service;

import com.chk.pojo.Books;

import java.util.List;

public interface BookService {
    //增加一个Book
    int addBook(Books book);
    //根据id删除一个Book
    int deleteBookById(int id);
    //更新Book
    int updateBook(Books books);
    //根据id查询,返回一个Book
    Books queryBookById(int id);
    //查询全部Book,返回list集合
    List<Books> queryAllBook();
}

实现类:BookServiceImpl

package com.chk.service;

import com.chk.mapper.BookMapper;
import com.chk.pojo.Books;
import java.util.List;

public class BookServiceImpl implements BookService {
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    public int addBook(Books book) {
        return bookMapper.addBook(book);
    }

    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    public List<Books> queryAllBook() {
        return bookMapper.queryAllBook();
    }
}

OK，到此，底层需求操作编写完毕！

Spring层

1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池

(不用大家去下载什么,一开始在pom.xml已经导入了依赖）

2、我们去编写Spring整合Mybatis的相关的配置文件

spring-mapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 配置整合mybatis -->
    <!-- 1.关联数据库文件 -->
    <context:property-placeholder location="classpath:database.properties"/>

    <!-- 2.数据库连接池 -->
    <!--数据库连接池
        dbcp 半自动化操作 不能自动连接
        c3p0 自动化操作（自动的加载配置文件 并且设置到对象里面）
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>

        <!-- c3p0连接池的私有属性 -->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!-- 关闭连接后不自动commit -->
        <property name="autoCommitOnClose" value="false"/>
        <!-- 获取连接超时时间 -->
        <property name="checkoutTimeout" value="10000"/>
        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

    <!-- 3.配置SqlSessionFactory对象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 -->
    <!--解释 ：https://www.cnblogs.com/jpfss/p/7799806.html-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 给出需要扫描Dao接口包 -->
        <property name="basePackage" value="com.chk.mapper"/>
    </bean>
</beans>

3、Spring整合service层

spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 扫描service相关的bean -->
    <context:component-scan base-package="com.chk.service" />

    <!--BookServiceImpl注入到IOC容器中-->
    <bean id="BookServiceImpl" class="com.chk.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!-- 配置事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
    </bean>
</beans>

Spring层搞定!

SpringMVC层

1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <!--DispatcherServlet-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!--一定要注意:我们这里加载的是总的配置文件，之前被这里坑了！-->
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--encodingFilter-->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--Session过期时间-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>

</web-app>

2、spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd
   http://www.springframework.org/schema/mvc
   https://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 配置SpringMVC -->
    <!-- 1.开启SpringMVC注解驱动 -->
    <mvc:annotation-driven />
    <!-- 2.静态资源默认servlet配置-->
    <mvc:default-servlet-handler/>

    <!-- 3.配置jsp 显示ViewResolver视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <!-- 4.扫描web相关的bean -->
    <context:component-scan base-package="com.chk.controller" />

</beans>

3、Spring配置整合文件，applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">
    <import resource="spring-mapper.xml"/>
    <import resource="spring-service.xml"/>
    <import resource="spring-mvc.xml"/>
</beans>

配置文件，暂时结束

Controller 和视图层编写

1、BookController 类编写，方法一：查询全部书籍

@Controller
@RequestMapping("/book")
public class BookController {

   @Autowired
   @Qualifier("BookServiceImpl")
   private BookService bookService;

   @RequestMapping("/allBook")
   public String list(Model model) {
       List<Books> list = bookService.queryAllBook();
       model.addAttribute("list", list);
       return "allBook";
  }
}

2、编写首页 index.jsp

<!DOCTYPE HTML>
<html>
<head>
   <title>首页</title>
   <style type="text/css">
       a {
           text-decoration: none;
           color: black;
           font-size: 18px;
      }
       h3 {
           width: 180px;
           height: 38px;
           margin: 100px auto;
           text-align: center;
           line-height: 38px;
           background: deepskyblue;
           border-radius: 4px;
      }
   </style>
</head>
<body>

<h3>
   <a href="${pageContext.request.contextPath}/book/allBook">点击进入列表页</a>
</h3>
</body>
</html>

3、书籍列表页面 allBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
   <title>书籍列表</title>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <!-- 引入 Bootstrap -->
   <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>

<div class="container">

   <div class="row clearfix">
       <div class="col-md-12 column">
           <div class="page-header">
               <h1>
                   <small>书籍列表 —— 显示所有书籍</small>
               </h1>
           </div>
       </div>
   </div>

   <div class="row">
       <div class="col-md-4 column">
           <a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增</a>
       </div>
   </div>

   <div class="row clearfix">
       <div class="col-md-12 column">
           <table class="table table-hover table-striped">
               <thead>
               <tr>
                   <th>书籍编号</th>
                   <th>书籍名字</th>
                   <th>书籍数量</th>
                   <th>书籍详情</th>
                   <th>操作</th>
               </tr>
               </thead>

               <tbody>
               <c:forEach var="book" items="${requestScope.get('list')}">
                   <tr>
                       <td>${book.getBookID()}</td>
                       <td>${book.getBookName()}</td>
                       <td>${book.getBookCounts()}</td>
                       <td>${book.getDetail()}</td>
                       <td>
                           <a href="${pageContext.request.contextPath}/book/toUpdateBook?id=${book.getBookID()}">更改</a> |
                           <a href="${pageContext.request.contextPath}/book/del/${book.getBookID()}">删除</a>
                       </td>
                   </tr>
               </c:forEach>
               </tbody>
           </table>
       </div>
   </div>
</div>
</body>
</html>

4、BookController 类编写，方法二：添加书籍

@RequestMapping("/toAddBook")
public String toAddPaper() {
   return "addBook";
}

@RequestMapping("/addBook")
public String addPaper(Books books) {
   System.out.println(books);
   bookService.addBook(books);
   return "redirect:/book/allBook";
}

5、添加书籍页面：addBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>
<head>
   <title>新增书籍</title>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <!-- 引入 Bootstrap -->
   <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">

   <div class="row clearfix">
       <div class="col-md-12 column">
           <div class="page-header">
               <h1>
                   <small>新增书籍</small>
               </h1>
           </div>
       </div>
   </div>
   <form action="${pageContext.request.contextPath}/book/addBook" method="post">
      书籍名称：<input type="text" name="bookName"><br><br><br>
      书籍数量：<input type="text" name="bookCounts"><br><br><br>
      书籍详情：<input type="text" name="detail"><br><br><br>
       <input type="submit" value="添加">
   </form>
</div>
</body>
</html>

6、BookController 类编写，方法三：修改书籍

@RequestMapping("/toUpdateBook")
public String toUpdateBook(Model model, int id) {
   Books books = bookService.queryBookById(id);
   System.out.println(books);
   model.addAttribute("book",books );
   return "updateBook";
}

@RequestMapping("/updateBook")
public String updateBook(Model model, Books book) {
   System.out.println(book);
   bookService.updateBook(book);
   Books books = bookService.queryBookById(book.getBookID());
   model.addAttribute("books", books);
   return "redirect:/book/allBook";
}

7、修改书籍页面 updateBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
   <title>修改信息</title>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <!-- 引入 Bootstrap -->
   <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">

   <div class="row clearfix">
       <div class="col-md-12 column">
           <div class="page-header">
               <h1>
                   <small>修改信息</small>
               </h1>
           </div>
       </div>
   </div>

   <form action="${pageContext.request.contextPath}/book/updateBook" method="post">
       <input type="hidden" name="bookID" value="${book.getBookID()}"/>
      书籍名称：<input type="text" name="bookName" value="${book.getBookName()}"/>
      书籍数量：<input type="text" name="bookCounts" value="${book.getBookCounts()}"/>
      书籍详情：<input type="text" name="detail" value="${book.getDetail() }"/>
       <input type="submit" value="提交"/>
   </form>
</div>
</body>
</html>

8、BookController 类编写，方法四：删除书籍

@RequestMapping("/del/{bookId}")
public String deleteBook(@PathVariable("bookId") int id) {
   bookService.deleteBookById(id);
   return "redirect:/book/allBook";
}

配置Tomcat，然后运行

我用的是IDEA,如果同学们用的是esclipse的话就还和以前一样配置tomcat
如果用idea启动这个项目不了,十有八九是因为一开始创建maven项目的时候创建的是空白项目。请跟我这样做往lib里添加jar包。

esclipse如果遇到了类似问题,自行百度怎么往lib下添加jar包但是一般esclipse创建maven的时候只要勾选webapp就没问题

1.软嵌企业框架期中复习-SSM整合

前言

数据库环境

基本环境搭建

1、新建一Maven项目（我起名ssmbuild） 勾选webapp。 添加web的支持

2、导入相关的pom依赖！（奖以下代码复制到pom.xml中）

3、Maven资源过滤设置

4、建立基本结构和配置框架！

Mybatis层编写

1、数据库配置文件 database.properties

2、编写MyBatis的核心配置文件 mybatis-config.xml

3、编写数据表对应的实体类 com.chk.pojo.Books

4、编写 Mapper层的 Mapper接口

5、编写接口对应的 Mapper.xml 文件。

6、编写Service层的接口和实现类

Spring层

1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池

2、我们去编写Spring整合Mybatis的相关的配置文件

3、Spring整合service层

SpringMVC层

1、web.xml

2、spring-mvc.xml

3、Spring配置整合文件，applicationContext.xml
