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

3.2 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>
<java.version>1.8</java.version>
<dubbo-spring-boot>2.0.0</dubbo-spring-boot>
</properties>
<dependencies>
<!-- Spring Boot dependencies -->

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<!--Spring Boot web -->
<dependency>

<!-- Spring Boot Test 依赖 -->

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。
