springBoot+dubbo消費端的使用

springBoot+dubbo服務提供者的使用

zookeeper安裝

• 基于全注解方式

1. pom.xml檔案(引入springBoot+dubbo服務提供者的使用裡建立的接口項目和dubbo依賴)

   <?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
       <modelVersion>4.0.0</modelVersion>
       <parent>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-parent</artifactId>
           <version>2.1.8.RELEASE</version>
           <relativePath/> <!-- lookup parent from repository -->
       </parent>
       <groupId>com.dubbo</groupId>
       <artifactId>consumer</artifactId>
       <version>0.0.1-SNAPSHOT</version>
       <name>consumer</name>
       <description>Demo project for Spring Boot</description>
   
       <properties>
           <java.version>1.8</java.version>
       </properties>
   
       <dependencies>
           <dependency>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-web</artifactId>
           </dependency>
   
           <dependency>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-test</artifactId>
               <scope>test</scope>
           </dependency>
   
           <!--自定義接口類-->
           <dependency>
               <groupId>com.dubbo</groupId>
               <artifactId>service</artifactId>
               <version>1.0-SNAPSHOT</version>
           </dependency>
   
           <!--引入dubbo-->
           <dependency>
               <groupId>com.alibaba.boot</groupId>
               <artifactId>dubbo-spring-boot-starter</artifactId>
               <version>0.2.0</version>
           </dependency>
   
       </dependencies>
   
       <build>
           <plugins>
               <plugin>
                   <groupId>org.springframework.boot</groupId>
                   <artifactId>spring-boot-maven-plugin</artifactId>
               </plugin>
           </plugins>
       </build>
   
   </project>
   
              

2. application.properties配置檔案

   #提供方應用資訊，用于計算依賴關系

   dubbo.application.name=dubboConsumer

   #使用zookeeper注冊中心

   dubbo.registry.address=zookeeper://127.0.0.1:2181

   

3. springBoot啟動類添加@EnableDubbo注解

   

4. 引用服務提供者提供的接口

   

5. 通路DubboTestController

   

• 基于XML方式

  1. 使用上面的pom.xml檔案
  2. 建立xml配置檔案

     

     <?xml version="1.0" encoding="UTF-8"?>
     <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
            xmlns="http://www.springframework.org/schema/beans"
            xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
            http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
     
         <!-- 提供方應用資訊，用于計算依賴關系 -->
         <dubbo:application name="dubboConsumer"/>
     
         <!-- 使用zookeeper注冊中心 -->
         <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
     
         <!-- 将該接口暴露到dubbo中 -->
         <dubbo:reference interface="com.dubbo.service.DubboTestService" id="dubboTestService" group="test" version="1.0.0"/>
     </beans>
     
                

  3. 執行

     import com.dubbo.service.DubboTestService;
     import org.springframework.context.support.ClassPathXmlApplicationContext;
     
     
     public class ConsumerApplication {
     
         public static void main(String[] args) {
            
             ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("consumer.xml");
             DubboTestService dubboTestService = context.getBean("dubboTestService", DubboTestService.class);
             System.out.println(dubboTestService.getTestResult());
         }
     }
