[【SSM】Eclipse使用Maven创建Web项目+整合SSM框架]

自己接触ssm框架有一段时间了，从最早的接触新版ITOO项目的（SSM/H+Dobbu zk），再到自己近期来学习到的《淘淘商城》一个ssm框架的电商项目。用过，但是还真的没有自己搭建过，一直都是用别人搭建好的。所以，从网上找了一些材料，结合自己来解决过程中的一些问题，使自己对ssm框架理解更加深了，不为分享，只是总结一下，下次有机会再搭建的时候，直接看自己的博客，省得找了！

一、准备环境：
maven：apache-maven-3.2.3
jdk：jdk1.8.0_25
tomcat：tomcat-6.0.37
二、配置Maven、jdk
1、Window——>Preferences——>Maven——>设置自己的Settings
2、Window——>Preferences——>Java——>Installed JREs——>Add

三、新建Maven项目：
1、右击——>New（或者是File——>New）——>other——>Maven——>Maven Project——>Next

2、这时候，我们就成功创建出一个Maven项目了，项目结构如下图：

3、右击项目，选择Properties进行一些配置：

   到这里，我们的Maven项目就建好了，接下来，我们来整合搭建SSM（[spring](http://lib.csdn.net/base/javaee) MVC + Spring + Mybatis）

首先我们来配置一些整合框架所必须要的jar包，也就是来配置我们的pom文件，然后直接alt+f5，保存后，就会自动下载，存放在之前配置好的本地maven仓库中。
pox.xml配置依赖的内容：

    </build>    
</project>    

2、在src/main/resources下添加配置文件：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" xmlns:p="http://www.springframework.org/schema/p"    
    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-3.1.xsd      
                        http://www.springframework.org/schema/context      
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd      
                        http://www.springframework.org/schema/mvc      
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    
                            
    <!-- 使用注解式注入 -->    
    <context:annotation-config />    
        
    <!-- 自动扫描 -->    
    <context:component-scan base-package="com.ssm" />    
        
    <!-- 导入DAO配置 -->    
    <import resource="spring-dao.xml"/>    
        
    <!-- 导入数据库配置 -->    
    <import resource="spring-db.xml"/>    
        
    <!-- 导入数据库配置 -->    
    <import resource="spring-tx.xml"/>    
        
</beans>    

配置数据库连接池：jdbc.properties

driver=com.mysql.jdbc.Driver    
url=jdbc:mysql://localhost:3306/maven_ssm    
username=root    
password=root    
#定义初始连接数    
initialSize=0    
#定义最大连接数    
maxActive=20    
#定义最大空闲    
maxIdle=20    
#定义最小空闲    
minIdle=1    
#定义最长等待时间    
maxWait=60000    

配置日志：log4j.properties

#定义LOG输出级别    
log4j.rootLogger=INFO,Console,File    
#定义日志输出目的地为控制台    
log4j.appender.Console=org.apache.log4j.ConsoleAppender    
log4j.appender.Console.Target=System.out    
#可以灵活地指定日志输出格式，下面一行是指定具体的格式    
log4j.appender.Console.layout = org.apache.log4j.PatternLayout    
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n    
    
#文件大小到达指定尺寸的时候产生一个新的文件    
log4j.appender.File = org.apache.log4j.RollingFileAppender    
#指定输出目录    
log4j.appender.File.File = logs/ssm.log    
#定义文件最大大小    
log4j.appender.File.MaxFileSize = 10MB    
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志    
log4j.appender.File.Threshold = ALL    
log4j.appender.File.layout = org.apache.log4j.PatternLayout    
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n    

配置我们的ioc注入：spring-dao.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:p="http://www.springframework.org/schema/p"

                        http://www.springframework.org/schema/mvc      
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    
                            
                            
    <!-- DAO接口所在包名，Spring会自动查找其下的类 -->    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">    
        <!--basePackage指定要扫描的包，在此包之下的映射器都会被搜索到。    
         可指定多个包，包与包之间用逗号或分号分隔-->    
        <property name="basePackage" value="com.ssm.dao" />    
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>    
    </bean>

        <property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>    
    </bean>    
        
</beans>    

配置spring的事务管理器：spring-tx.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:p="http://www.springframework.org/schema/p"    
    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-3.1.xsd      
                        http://www.springframework.org/schema/context      
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd

        <property name="dataSource" ref="dataSource" />    
    </bean>    
        
</beans>    

接下来，我们来整合spring mvc：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:p="http://www.springframework.org/schema/p"    
    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-3.1.xsd

到这里，我们的ssm框架就完成了，下面，我们来个实现：
在src/main/java下分别添加我们的dao包，service包，还有controller包.包里面添加相应的类，效果图如下：

UserController.java:

package com.ssm.controller;    
    
import java.util.List;    
    
import javax.annotation.Resource;    
import javax.servlet.http.HttpServletRequest;    
    
import org.springframework.stereotype.Controller;    
import org.springframework.ui.Model;    
import org.springframework.web.bind.annotation.RequestMapping;    
    
import com.ssm.dto.User;    
import com.ssm.service.IUserService;    
    
@Controller    
@RequestMapping("/user")    
public class UserController {    
    @Resource    
    private IUserService userService;    
        
    @RequestMapping("/userList")    
    public String userList(HttpServletRequest request,Model model){    
        List<User> uList = userService.getAllUser();    
        model.addAttribute("uList", uList);    
        return "userList";    
    }    
        
    @RequestMapping("/showUser")    
    public String showUser(HttpServletRequest request,Model model){    
        int userId = Integer.parseInt(request.getParameter("id"));    
        User user = userService.getUserById(userId);    
        model.addAttribute("user", user);    
        return "showUser";    
    }    
        
    @RequestMapping("/addUserUI")    
    public String addUserUI(){    
        return "addUser";    
    }    
        
    @RequestMapping("/addUser")    
    public String addUser(HttpServletRequest request,Model model){    
        User user = new User();    
        user.setName(String.valueOf(request.getParameter("name")));    
        user.setPassword(String.valueOf(request.getParameter("password")));    
        user.setAge(Integer.parseInt(String.valueOf(request.getParameter("age"))));    
        userService.addUser(user);    
        return "redirect:/user/userList";    
    }    
}    

IUserDao.java:

package com.ssm.dao;    
    
import java.util.List;    
import java.util.Map;    
    
import com.ssm.dto.User;    
    
public interface IUserDao {    
        
    public User queryByPrimaryKey(Integer id);    
        
    public List<User> queryUserByBatch(Map<String,Object> params);    
        
    public void insertUser(User user);    
        
    public void insertUserByBatch(List<User> list);    
        
    public void deleteByPrimaryKey(Integer id);    
        
    public void delteUserByBatch(Map<String,Object> params);    
        
    public void updateByPrimaryKey(Integer id);    
    
    public List<User> getAllUser();    
        
}    

User.java:

package com.ssm.dto;    
    
public class User {    
    private Integer id;    
    
    private String name;    
    
    private String password;    
    
    public Integer getId() {    
        return id;    
    }    
    
    public void setId(Integer id) {    
        this.id = id;    
    }    
    
    public String getName() {    
        return name;    
    }    
    
    public void setName(String name) {    
        this.name = name;    
    }    
    
    public String getPassword() {    
        return password;    
    }    
    
    public void setPassword(String password) {    
        this.password = password == null ? null : password.trim();    
    }    
}

import java.util.List;

public interface IUserService {

    public void addUser(User user);    
    
    public List<User> getAllUser();    
}    

UserServiceImpl.java:

接下来就是我们的静态页面了jsp文件了，在WEB-INF文件夹下新建jsp文件夹，添加userinfo.jsp

userinfo.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>    
<%    
String path = request.getContextPath();   
String basePath=request.getSSScheme()+"://request.getServerName()"+":"+request.getServerPort+Path+  
  "/"%>  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">    
<html>    
  <head>    
    <base href="<%=basePath%>">    
        
    <title>My JSP 'userinfo.jsp' starting page</title>    
        
    <meta http-equiv="pragma" content="no-cache">    
    <meta http-equiv="cache-control" content="no-cache">

    <!--  
    <link rel="stylesheet" type="text/css" href="styles.css">

  </head>    
      
  <body>    
    <form id="addUser" action="user/addUser" method="post">     
        userName: <input id="name" name="name" /><br/>     
        password: <input id="password" name="password" /><br/>    
        <input type="submit" value="添加新用户"/>     
    </form>    
  </body>    
</html>     

哦,忘记配置tomcat，配置一下tomcat，然后部署发布项目，进行测试

总结： 真心知道用maven之后，我们搭框架真的方便多了，最起码不用个顶个的去找jar包，然后逐一的 导入，只需要在pom文件里面配置一下依赖，就好了。虽然说比较简单，可是可能是自己没有动手弄过吧，期间出了各种各样的错，或者说是失误，但是，总之，耗时一天半，总算是通了，这也是收获， 加油吧，少（qing）年。
