SpringMVC和Dubbo的整合
源码：https://github.com/shengfenglai/SpringMVCWithDubboAdmin.git
一.准备maven项目
mvn archetype:generate -DgroupId=com.lsf.app -DartifactId=coder-center -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false 创建coder-center项目，服务的具体实现
mvn archetype:generate -DgroupId=com.lsf.app -DartifactId=coder-center-api -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false 创建coder-center-api项目，暴露服务
mvn archetype:generate -DgroupId=cn.lsf.app -DartifactId=appserver -DarchetypeArtifactId=maven-archetype-webapp -DinteractivMode=false 创建appserver web项目，消费各服务
注释：
mvn archetype:generate 固定格式
-DgroupId 组织标识（包名）
-DartifactId 项目名称
-DarchetypeArtifactId 特定ArchetypeId，maven-archetype-quickstart，创建一个Java Project；maven-archetype-webapp，创建一个Web Project
-DinteractiveMode 是否使用交互模式
然后把项目导入Eclipse中，项目结构图如下
二.服务提供者
1.在coder-center-api中定义接口，用来暴露出去
package com.shengfeng.user.service;
import com.shengfeng.user.bean.UserBean;
public interface UserService {
long addUser();
UserBean getUserByUserId();
}
2.在coder-center-api中定义bean，用来暴露出去
package com.shengfeng.user.bean;
import java.io.Serializable;
public class UserBean implements Serializable{
private static final long serialVersionUID = -5621716534400078000L;
private long id ;
private String username;//用户名
private String password;//密码
private String level;//等级
private int sex;//性别
private String mobilephone;//手机号
private String img;// 头像
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getLevel() {
return level;
}
public void setLevel(String level) {
this.level = level;
}
public int getSex() {
return sex;
}
public void setSex(int sex) {
this.sex = sex;
}
public String getMobilephone() {
return mobilephone;
}
public void setMobilephone(String mobilephone) {
this.mobilephone = mobilephone;
}
public String getImg() {
return img;
}
public void setImg(String img) {
this.img = img;
}
}
3.在coder-center中的pom.xml添加依赖，把需要用的jar引进来
<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/maven-v4_0_0.xsd">

<artifactId>zkclient</artifactId>
<version>0.4</version>
</dependency>
</dependencies>
</project>
4.在coder-center中实现coder-center-api的接口
package com.shengfeng.user.service.impl;
import com.shengfeng.user.bean.UserBean;
import com.shengfeng.user.service.UserService;
/**
* UserService impl
*
*/
public class UserServiceImpl implements UserService {
public long addUser() {
return 0;
}
public UserBean getUserByUserId() {
UserBean userBean = new UserBean();
userBean.setUsername("shengfeng");
return userBean;
}
}
5.在coder-center中将实现的服务暴露出来，provider.xml配置文件如下
<?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: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://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <!-- 提供方应用信息，用于计算依赖关系 --> <dubbo:application name="coder-center-provider" /> <!-- 使用zookeeper注册中心暴露服务地址 --> <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" /> <!-- 用dubbo协议在20880端口暴露服务 --> <dubbo:protocol name="dubbo" port="20880" /> <!-- 声明需要暴露的服务接口 --> <dubbo:service interface="com.shengfeng.user.service.UserService" ref="userService" /> <bean id="userService" class="com.shengfeng.user.service.impl.UserServiceImpl" /> </beans>
6.服务启动类
package com.shengfeng.user.main;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Provider {
public static ClassPathXmlApplicationContext context;
public static void main(String[] args) {
context = new ClassPathXmlApplicationContext(new String[] { "provider.xml" });
context.start();
System.out.println("coder-center 启动成功");
while (true) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
7.启动main方法之后，去dubbo-admin管理平台上看是否已经将提供的服务暴露到上面
查看提供者
这样就完成了一半，还剩下一个消费者
三.服务消费者
1.在appserver项目中先在pom.xml文件中引入相应的jar包
<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/maven-v4_0_0.xsd">

<dependency>

<artifactId>zkclient</artifactId>
<version>0.4</version>
</dependency>
</dependencies>
</project>
2.消费服务的类UserAction
package com.shengfeng.user.action;
import java.io.IOException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.shengfeng.user.service.UserService;
public class UserAction {
public static void main(String[] args) throws IOException {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "consumer.xml" });
context.start();
System.out.println("consumer启动成功");
UserService userService = (UserService) context.getBean("userService");
System.out.println("username:" + userService.getUserByUserId().getUsername());
while (true) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
这里需要说一下，不要消费完服务就关闭，这样的话它都到不了注册中心那里，也就是dubbo-admin那里的消费者一直会显示不出来，这里的解决办法是让它睡1秒
3.消费服务的配置文件consumer.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: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://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 --> <dubbo:application name="consumer-appserver" /> <!-- 使用zookeeper注册中心暴露发现服务地址 --> <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" default="true"/> <!-- 引入服务接口 --> <dubbo:reference id="userService" interface="com.shengfeng.user.service.UserService" /> </beans>
4.启动UserAction的main方法，然后去dubbo-admin管理平台上去看是否有消费者的相应信息
查看消费者
然后可以在eclipse控制上看到可以消费到 提供者提供的服务
比较简单，不过可以试试手~
