SpringBoot下的Dubbo和Zookeeper整合

最近一直在学各种分布式的内容，学到了dubbo分布式服务框架就想写个小demo使用一下，但是由于我要整合在SpringBoot框架中，SpringBoot框架毕竟提倡的是java注解配置，XML文件不提倡，所以只能利用@ImportResource这个注解来引入dubbo配置的XML文件。

首先是Maven项目的Pom文件：

除了基本的SpringBoot的基本web配置jar包需要添加以下依赖(服务提供方和消费方一样)：

            com.alibaba
            dubbo
            2.5 . 3

                  //这个排除低版本的spring
                    org.springframework
                    spring




            org.apache.zookeeper
            zookeeper
            3.4 . 6

                //冲突排除
                    org.slf4j
                    slf4j-log4j12

                //冲突排除
                    log4j
                    log4j




            com.github.sgroschupf
            zkclient
            0.1

接下来是服务的提供方：

服务接口代码

 

public  interface  TestService {
public  String sayHello();
}

 

接口实现代码

@Service ( "testService" )
public  class  TestServiceImpl  implements  TestService {
    @Override
    public  String sayHello() {
        return  "hello dubbo" ;
    }
}

接下来是服务方的XML配置文件：

"1.0"  encoding= "UTF-8" ?>
"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 ">

    "provider"  />

    "zookeeper"  address= "zookeeper://127.0.0.1:2181"  />

    interface = "com.distributed.TestService"  ref= "testService" >

SpringBoot启动类（注意要引入XML配置文件）：

@SpringBootApplication
@ImportResource ( "classpath:provider.xml" ) //很重要
public  class  MyApplication {

    public  static  void  main(String[] args) {
        SpringApplication.run(MyApplication. class ,args);
    }

}

接下来是服务消费方

这里接口要和服务的提供方保持一致不能有区别。

配置文件：

"1.0"  encoding= "UTF-8" ?>
"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 ">

    "consumer"  />

    "zookeeper"  address= "zookeeper://127.0.0.1:2181"  />

    interface = "com.distributed.TestService"  id= "testService" >

　Controller类：

@RestController
public  class  MyController {
    @Autowired
    private  TestService testService;

    @RequestMapping
    public  String home(){
        return  testService.sayHello();
    }
}

　启动类：

@SpringBootApplication
@ImportResource ( "classpath:consumer.xml" )
public  class  MyApplication {
    public  static  void  main(String[] args) {
        SpringApplication.run(MyApplication. class ,args);
    }
}

　最后运行服务端和消费端，访问消费端的controller成功调用服务。。。
