SpringBoot整合dubbo（注解配置dubbo）
源码
GitHub：https://github.com/291685399/springboot-learning/tree/master/springboot-dubbo01
准备
1、在服务器或者本地搭建好zookeeper，具体可参考文章：https://blog.csdn.net/qq_35620501/article/details/87519306
2、在服务器或者本地搭建好dubbo-admin，具体可参考文章：https://blog.csdn.net/qq_35620501/article/details/89037354
代码
- 新建空的maven工程，命名为springboot-dubbo01
项目目录结构如下图：
pom.xml：
<parent>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-starter-parentartifactId>
<version>2.0.0.RELEASEversion>
parent>
<modules>
<module>springboot-dubbo01-api-webmodule>
<module>springboot-dubbo01-service-implmodule>
<module>springboot-dubbo01-servicemodule>
modules>
- 新建模块，命名为springboot-dubbo01–service
service主要是用来存放在实体类、Enum、工具类、service等
项目结构如下图：
DemoService：
public interface DemoService {
public List<Message> findMessage();
}
Message:
public class Message implements Serializable {
private int id;
private String city;
private String time;
private String weather;
public Message() {}
public int getId() {return id;}
public void setId(int id) {this.id = id;}
public String getCity() {return city;}
public void setCity(String city) {this.city = city;}
public String getTime() {return time;}
public void setTime(String time) {this.time = time;}
public String getWeather() {return weather;}
public void setWeather(String weather) {this.weather = weather;}
}
ApiResponse：
public class ApiResponse implements Serializable {
private int code;
private String msg;
private Object data;
public ApiResponse() {}
public ApiResponse(int code, String msg) {
this.code = code;
this.msg = msg;
}
public ApiResponse(int code, String msg, Object data) {
this.code = code;
this.msg = msg;
this.data = data;
}
public int getCode() {return code;}
public void setCode(int code) {this.code = code;}
public String getMsg() {return msg;}
public void setMsg(String msg) {this.msg = msg;}
public Object getData() {return data;}
public void setData(Object data) {this.data = data;}
}
- 新建模块，命名为springboot-dubbo01-service-impl
service-impl主要是存放service接口实现类、持久层的实现

DemoServiceImpl：
@Service(timeout = 6000)//这个service是dubbo的service
public class DemoServiceImpl implements DemoService {
@Autowired
private DemoMapper demoMapper;
@Override
public List<Message> findMessage() {
return demoMapper.findMessage();
}
}
DemoMapper：
public interface DemoMapper {
public List<Message> findMessage();
}
DemoMappe.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" >

- 新建模块，命名为springboot-dubbo01-api-web
api主要是用来存放controller、handler、interceptor

DemoController：
注意：
这里不能使用@Autowired注入bean，要使用dubbo中的注解@Reference注入bean和dubbo接口
@RestController
public class DemoController {
@Reference
private DemoService demoService;
@RequestMapping(value = "/query")
public ApiResponse demo() {
try {
List<Message> messageList = demoService.findMessage();
return new ApiResponse(200, "操作成功", messageList);
} catch (Exception e) {
e.printStackTrace();
return new ApiResponse(500, "系统异常");
}
}
}
application.properties：
# tomcat
server.port=8080
# dubbo
spring.dubbo.application.name=demo-consumer
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.scan=com.wyj.controller
测试
-
先运行service-impl的服务，再启动api的服务，原则上是先启动service-impl的
-
访问
浏览器访问：http://127.0.0.1:8080/query
查看监控中心
- 访问dubbo-admin
点击服务治理中的服务
从监控中心可以看到com.wyj.service.DemoService这个接口能够正常注册到zookeeper中，并被api给消费
