Dubbo在Spring和Spring Boot中的使用详解

一、在Spring中使用Dubbo

1、Maven依赖

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>dubbo</artifactId>
  <version>2.5.3.6</version>
  <exclusions>
    <exclusion>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
    </exclusion>
    <exclusion>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.springframework</groupId>
      <artifactId>spring</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.alibaba</groupId>
      <artifactId>fastjson</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>com.github.sgroschupf</groupId>
  <artifactId>zkclient</artifactId>
  <version>0.1</version>
</dependency>

2、DUBBO生产者注册到zookeeper的xml配置方式

<?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
    ">
 <!-- 具体的实现bean -->
 <bean id="demoService"
 class="com.unj.dubbotest.provider.impl.DemoServiceImpl" />
 <!-- 提供方应用信息，用于计算依赖关系 -->
 <dubbo:application name="xixi_provider" />
 <!-- 使用multicast广播注册中心暴露服务地址 
 <dubbo:registry address="multicast://224.5.6.7:1234" />-->
 <!-- 使用zookeeper注册中心暴露服务地址 -->
 <dubbo:registry address="zookeeper://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.unj.dubbotest.provider.DemoService" version="mys"
 ref="demoService" />
</beans>

3、DUBBO消费者注册到zookeeper的xml配置方式

<?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 
    ">
 <!-- 消费者应用信息，用于提供依赖关系 -->
 <dubbo:application name="consumer-of-helloworld-app" />
 <!-- 注册地址，用于消费者寻找服务 -->
 <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181,10.128.3.33:2181" />
 <dubbo:consumer timeout="5000" />
 <!-- 引用的服务 -->
 <dubbo:reference id="demoService"interface="com.unj.dubbotest.provider.DemoService" version="mys" />
</beans>

二、在Spring Boot中使用Dubbo

在Spring Boot中使用Dubbo，不需要使用xml的方式来配置生产者和消费者，需要使用@Bean注解的方式来进行配置。

1、Maven依赖

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
  <version>1.2.5.RELEASE</version>
</dependency>
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter</artifactId>
  <version>1.2.5.RELEASE</version>
</dependency>
<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>dubbo</artifactId>
  <version>2.5.3.6</version>
  <exclusions>
    <exclusion>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
    </exclusion>
    <exclusion>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.springframework</groupId>
      <artifactId>spring</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.alibaba</groupId>
      <artifactId>fastjson</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>com.github.sgroschupf</groupId>
  <artifactId>zkclient</artifactId>
  <version>0.1</version>
</dependency>

2、Dubbo基础配置

public class DubboBaseConfig {
  @Bean
  public RegistryConfig registry() {
    RegistryConfig registryConfig = new RegistryConfig();
    registryConfig.setAddress("127.0.0.1:2181");
    registryConfig.setProtocol("zookeeper");
    return registryConfig;
  }
  @Bean
  public ApplicationConfig application() {
    ApplicationConfig applicationConfig = new ApplicationConfig();
    applicationConfig.setName("testApp");
    return applicationConfig;
  }
  @Bean
  public MonitorConfig monitorConfig() {
    MonitorConfig mc = new MonitorConfig();
    mc.setProtocol("registry");
    return mc;
  }
  @Bean
  public ReferenceConfig referenceConfig() {
    ReferenceConfig rc = new ReferenceConfig();
    rc.setMonitor(monitorConfig());
    return rc;
  }
  @Bean
  public ProtocolConfig protocol() {
    ProtocolConfig protocolConfig = new ProtocolConfig();
    protocolConfig.setPort(20880);
    return protocolConfig;
  }
  @Bean
  public ProviderConfig provider() {
    ProviderConfig providerConfig = new ProviderConfig();
    providerConfig.setMonitor(monitorConfig());
    return providerConfig;
  }
}

3、Dubbo生产者配置，需要继承Dubbo基础配置

@Configuration
public class ExportServiceConfig extends DubboBaseConfig {
  @Bean
  public ServiceBean<Person> personServiceExport(Person person) {
    ServiceBean<Person> serviceBean = new ServiceBean<Person>();
    serviceBean.setProxy("javassist");
    serviceBean.setVersion("myversion");
    serviceBean.setInterface(Person.class.getName());
    serviceBean.setRef(person);
    serviceBean.setTimeout(5000);
    serviceBean.setRetries(3);
    return serviceBean;
  }
}

4、Dubbo消费者配置，需要继承Dubbo基础配置

@Configuration
public class ReferenceConfig extends DubboBaseConfig {
  @Bean
  public ReferenceBean<Person> person() {
    ReferenceBean<Person> ref = new ReferenceBean<>();
    ref.setVersion("myversion");
    ref.setInterface(Person.class);
    ref.setTimeout(5000);
    ref.setRetries(3);
    ref.setCheck(false);
    return ref;
  }
}

5、直接从Spring容器中拿去Person接口即可。
