                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

二.在父项目中添加子模块DubboPojo

1.修改pom文件，添加lombok依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>Days61DubboSSM</artifactId>
        <groupId>com.qfedu</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>DubboPojo</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.18</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>
</project>

2.新增pojo类，并且让该类实现序列化接口

package com.qfedu.pojo;

import lombok.Data;

import java.io.Serializable;

@Data
public class User implements Serializable {
    private String userId;
    private String username;
    private String password;
    private String email;
    private String tel;
    private int level;
    private int integral;
    private int ifNew;
}

三. 在父项目中添加子模块DubboDao

1.修改pom文件，Dao模块依赖于Pojo模块

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>Days61DubboSSM</artifactId>
        <groupId>com.qfedu</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>DubboDao</artifactId>

    <dependencies>
        <dependency>
            <groupId>com.qfedu</groupId>
            <artifactId>DubboPojo</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>
                com.springsource.org.aspectj.weaver
            </artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
        </dependency>
    </dependencies>
</project>

2.在src中添加Dao接口的java代码

package com.qfedu.dao;

import com.qfedu.pojo.User;

import java.util.List;

public interface IUserDao {

    List<User> getAllUsers();
}

3.在resources中添加dao接口对应的mapper的xml映射文件

<?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">
<!-- 整个映射文件为mapper节点，里面包含namespace属性 -->
   <mapper namespace="com.qfedu.dao.IUserDao">
   
   <select id="getAllUsers" resultType="user">
      select user_id userId, user_name username, password, email, tel, level, integral, if_new ifNew from users
   </select>
</mapper>

四.在父项目中添加子模块DubboServiceContent

1.在当前模块中新增模块DubboServiceContentInterface

(1)新增接口

package com.qfedu.service;

import com.qfedu.pojo.User;

import java.util.List;

public interface IUserService {

    List<User> getAllUsers();
}

(2)pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>DubboServiceContent</artifactId>
        <groupId>com.qfedu</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>DubboServiceContentInterface</artifactId>
</project>

2.在当前模块中新增模块DubboServiceContentProvider

(1)新增接口对应的实现类UserServiceImpl

package com.qfedu.service.impl;

import com.qfedu.dao.IUserDao;
import com.qfedu.pojo.User;
import com.qfedu.service.IUserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

@Service
public class UserServiceImpl implements IUserService {

    @Resource
    private IUserDao userDao;

    @Override
    public List<User> getAllUsers() {
        return userDao.getAllUsers();
    }
}

(2)修改pom文件,该提供者依赖于接口，再添加tomcat的插件来运行该子模块

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <groupId>commons-io</groupId>
            <artifactId>commons-io</artifactId>
        </dependency>
    </dependencies>

    <build>
        <!--不过滤java下的xml文件-->
        <resources>
            <resource>
                <directory>src/main/java</directory>

      http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
   <context:component-scan base-package="com.qfedu.service" />
   
   <!-- 定义服务提供者在dubbo中的名称 -->
   <dubbo:application name="DubboServiceContentProvider"/>
   
   <!-- 配置dubbo协议， dubbo， RMI， hession -->
   <dubbo:protocol name="dubbo" port="20880" />
   
   <!-- 完成dubbo的注册 -->
   <!-- <dubbo:registry address="zookeeper://192.168.31.13:2181"></dubbo:registry> -->
   <dubbo:registry address="zookeeper://192.168.31.134:2181"></dubbo:registry>
   
   <!-- 将接口暴露给消费方 -->
   <dubbo:service interface="com.qfedu.service.IUserService" ref="userServiceImpl"></dubbo:service>
</beans>

(7)修改web.xml文件，来加载所有的配置文件

<?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_3_1.xsd"
         version="3.1">

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-*.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

3.修改当前子模块的pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>Days61DubboSSM</artifactId>
        <groupId>com.qfedu</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>DubboServiceContent</artifactId>
    <packaging>pom</packaging>

    <dependencies>
        <dependency>
            <groupId>com.qfedu</groupId>
            <artifactId>DubboDao</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

    <modules>
        <module>DubboServiceContentInterface</module>
        <module>DubboServiceContentProvider</module>
    </modules>

</project>

五.新增DubboPortal子模块

1.修改该模块的pom文件,分别添加依赖以及tomcat插件，当前模块依赖于接口（不能直接依赖于提供者）

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>Days61DubboSSM</artifactId>
        <groupId>com.qfedu</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>DubboPortal</artifactId>
    <packaging>war</packaging>

    <dependencies>
        <dependency>
            <groupId>com.qfedu</groupId>
            <artifactId>DubboServiceContentInterface</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <type>pom</type>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
        </dependency>
        <dependency>
            <groupId>com.101tec</groupId>
            <artifactId>zkclient</artifactId>
        </dependency>
    </dependencies>

    <build>
        <!--不过滤java下的xml文件-->
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <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>
        <plugins>

            <!-- 添加tomcat插件 -->
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <path>/</path>
                    <port>80</port>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

2.新增controller类

package com.qfedu.controller;

import com.qfedu.pojo.User;
import com.qfedu.service.IUserService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.util.List;

@RestController
public class UserController {

    @Resource
    private IUserService userService;

    @GetMapping("/Users")
    public List<User> getAllUsers(){
        return userService.getAllUsers();
    }
}

3.修改当前模块的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <display-name>Days94SSMDubboPortal</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- needed for ContextLoaderListener -->
   <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-*.xml</param-value>
   </context-param>

   <!-- Bootstraps the root web application context before servlet initialization -->
   <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>
  
  <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
   <servlet>
      <servlet-name>springDispatcherServlet</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath:springmvc.xml</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
   </servlet>

   <!-- Map all requests to the DispatcherServlet for handling -->
   <servlet-mapping>
      <servlet-name>springDispatcherServlet</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>
</web-app>

4.在resources下添加配置文件springmvc.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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
      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-4.3.xsd">

   <context:component-scan base-package="com.qfedu.controller" />
   
   <mvc:annotation-driven />
   
   <mvc:default-servlet-handler/>
</beans>

5.在resources下添加配置文件spring-dubbo.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:dubbo="http://code.alibabatech.com/schema/dubbo"
   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-4.3.xsd
      http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

   <dubbo:application name="DubboPortal"/>
   
   <!-- 完成dubbo的注册 -->
   <dubbo:registry address="zookeeper://192.168.31.134:2181"></dubbo:registry>
   
   <dubbo:reference interface="com.qfedu.service.IUserService" id="userService" />
</beans>

六.启动运行测试

1.启动zookeeper

2.启动provider对应的tomcat

3.启动protal消费者对应的tomcat

4.在浏览器中输入http://localhost/Users

5.页面上得到数据对应的json

[{"userId":"20190514112608","username":"张三","password":"zhangsan","email":"zhangsan@163.com","tel":"13679189439","level":1,"integral":0,"ifNew":1},

6.至此SSM整合dubbo完成

7.如果想分别监控提供者和消费者，可以配置dubbo-admin的war包来启动服务监控消费者和提供者
