• spring-boot系列:(一)整合dubbo


    spring-boot-2整合dubbo

    新框架学习,必须上手干。书读百遍,其义自见。

    本文主要介绍spring-boot-2整合dubbo,使用xml配置实现一个provider和consumer。

    1.创建Maven项目:

    spring-boot-parent:父工程,统一管理jar依赖,版本

        spring-boot-service:子工程,dubbo服务提供方

        spring-boot-web:子工程,dubbo服务消费方

    2.spring-boot-parent: 父工程,统一管理jar依赖,版本

    pom文件

        <!--集中定义依赖版本号-->
        <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>
    
        <!-- 就是管理版本的标签   其下的dependencies标签只是版本的管理 并不依赖jar-->
        <dependencyManagement>
            <dependencies>
                <dependency>
                    <!-- Import dependency management from Spring Boot -->
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-dependencies</artifactId>
                    <version>${spring-boot.version}</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
                <!-- Redis客户端 -->
                <dependency>
                    <groupId>redis.clients</groupId>
                    <artifactId>jedis</artifactId>
                    <version>${jedis.version}</version>
                </dependency>
            </dependencies>
        </dependencyManagement>

    3.spring-boot-service :子工程,dubbo服务提供方

    3.1 pom文件

        <properties>

            <dubbo-spring-boot>2.0.0</dubbo-spring-boot>
        </properties>
    
        <dependencies>

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

    3.2 新建HelloWorldService服务(接口和实现类)

    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">
    
        <!-- 提供方应用信息,用于计算依赖关系 -->
        <dubbo:application name="spring-boot-manager-service"  />
    
        <!-- 注册中心服务地址 -->
        <dubbo:registry id="zookeeper" protocol="zookeeper" address="${dubbo.registry.address}" />
    
        <!-- 用dubbo协议在30001 -->
        <dubbo:protocol name="dubbo" port="28080" />
    
        <!-- 声明需要暴露的服务接口 -->
        <dubbo:service interface="com.hao.persistence.service.HelloWorldService" ref="helloWorldService"
                       registry="zookeeper"/>
    
        <!-- 具体服务接口的实现 -->
        <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  设置启动类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("项目启动!");
        }
    }

    运行Application类main方法后,在dubbo控制台查看到我们注册的接口,如下所示,代表服务提供者Provider已经配置完成

     4.spring-boot-web:子工程,dubbo服务消费方

    4.1  pom文件

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

                    </exclusion>
                </exclusions>
            </dependency>
    
            <!-- zkClient -->

                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </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">
    
        <!-- 消费方服务名 -->
        <dubbo:application name="spring-boot-manager-web"  />
    
        <!-- 注册中心服务地址 -->
        <dubbo:registry id="zookeeper" protocol="zookeeper" address="${dubbo.registry.address}" />
    
        <!-- 引用helloWorldService 服务-->
        <dubbo:reference id="helloWorldService" interface="com.hao.persistence.service.HelloWorldService" check="false"
                       registry="zookeeper" protocol="dubbo" timeout="15000"/>
    
    </beans>

    4.4 application.properties

    这里将web的默认端口改为8081,防止端口冲突

    server.port=8081
    
    ## Dubbo 服务消费者配置
    #ZooKeeper
    dubbo.registry.address=10.10.55.69:2181
    
    logging.level.root=INFO

    4.5 启动类Application

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

    点击运行web项目的main方法,运行成功后如下所示,访问页面url,http://localhost:8081/getHello

    到此,简单的spring-boot-2整合dubbo服务完成。

    感谢各位老铁关注!

    关于最新的  dubbo-spring-boot-stater    的jar包,整合spring-boot自动装配(不用再写xml),健康检查特性,会在后续研究。
