spring-boot系列：（一）整合dubbo

spring-boot-2整合dubbo

新框架學習，必須上手干。書讀百遍，其義自見。

本文主要介紹spring-boot-2整合dubbo，使用xml配置實現一個provider和consumer。

1.創建Maven項目：

spring-boot-parent：父工程，統一管理jar依賴，版本

    spring-boot-service：子工程，dubbo服務提供方

    spring-boot-web：子工程，dubbo服務消費方

2.spring-boot-parent： 父工程，統一管理jar依賴，版本

pom文件

    <!--集中定義依賴版本號-->
    <properties>
        <maven_javadoc_version>3.0.1</maven_javadoc_version>
        <maven_surefire_version>2.19.1</maven_surefire_version>
        <spring-boot.version>2.1.2.RELEASE</spring-boot.version>
        <jedis.version>2.7.2</jedis.version>
    </properties>

    <!-- 就是管理版本的標簽 其下的dependencies標簽只是版本的管理 並不依賴jar-->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <!-- Import dependency management from Spring Boot -->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!-- Redis客戶端 -->
            <dependency>
                <groupId>redis.clients</groupId>
                <artifactId>jedis</artifactId>
                <version>${jedis.version}</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

 

3.spring-boot-service ：子工程，dubbo服務提供方

3.1 pom文件

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

            </plugin>
        </plugins>
    </build>

3.2 新建HelloWorldService服務（接口和實現類）

public interface HelloWorldService { String getHello(String msg); }

public class HelloWorldServiceImpl implements HelloWorldService { public String getHello(String msg) { return "spring boot dubbo start:" + msg; } }

3.3 配置dubbo-provider.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">

    <!-- 提供方應用信息，用於計算依賴關系 -->
    <dubbo:application name="spring-boot-manager-service"  />

    <!-- 注冊中心服務地址 -->
    <dubbo:registry id="zookeeper" protocol="zookeeper" address="${dubbo.registry.address}" />

    <!-- 用dubbo協議在30001 -->
    <dubbo:protocol name="dubbo" port="28080" />

    <!-- 聲明需要暴露的服務接口 -->
    <dubbo:service interface="com.hao.persistence.service.HelloWorldService" ref="helloWorldService" registry="zookeeper"/>

    <!-- 具體服務接口的實現 -->
    <bean id="helloWorldService" class="com.hao.persistence.service.impl.HelloWorldServiceImpl" />

</beans>

3.4 配置application.properties

#ZooKeeper地址 dubbo.registry.address={ip}:{port} logging.level.root=INFO

3.5  設置啟動類Application 

@SpringBootApplication @ImportResource("classpath:dubbo-provider.xml") public class Application { private static final Logger logger = LoggerFactory.getLogger(Application.class); public static void main(String[] args) { SpringApplication.run(Application.class, args); // logger.info("項目啟動!");
 } }

運行Application類main方法后，在dubbo控制台查看到我們注冊的接口，如下所示，代表服務提供者Provider已經配置完成

 

 4.spring-boot-web：子工程，dubbo服務消費方

4.1  pom文件

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

        </dependency>

    </dependencies>

            </plugin>
        </plugins>
    </build>

4.2 新建HelloWorldController

@RestController public class HelloWorldController { @Autowired private HelloWorldService helloWorldService; @RequestMapping("getHello") public String getHello(){ String msg = helloWorldService.getHello("haoprogrammer"); return msg; } }

4.3 dubbo配置文件 dubbo-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">

    <!-- 消費方服務名 -->
    <dubbo:application name="spring-boot-manager-web"  />

    <!-- 注冊中心服務地址 -->
    <dubbo:registry id="zookeeper" protocol="zookeeper" address="${dubbo.registry.address}" />

    <!-- 引用helloWorldService 服務-->
    <dubbo:reference id="helloWorldService" interface="com.hao.persistence.service.HelloWorldService" check="false" registry="zookeeper" protocol="dubbo" timeout="15000"/>

</beans>

 

4.4 application.properties

這里將web的默認端口改為8081，防止端口沖突

server.port=8081 ## Dubbo 服務消費者配置 #ZooKeeper dubbo.registry.address=10.10.55.69:2181 logging.level.root=INFO

4.5 啟動類Application

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

點擊運行web項目的main方法，運行成功后如下所示，訪問頁面url，http://localhost:8081/getHello

 

 

到此，簡單的spring-boot-2整合dubbo服務完成。

感謝各位老鐵關注！

關於最新的  dubbo-spring-boot-stater    的jar包，整合spring-boot自動裝配（不用再寫xml），健康檢查特性，會在后續研究。
