SpringBoot (七) ：SpringBoot 整合dubbo

Dubbo是什么

Dubbo是alibaba的一款开源软件，它是基于java的RPC调用框架。
Dubbo主要提供了三种功能：

提供了基于接口的远程调用接口
容错性和负载均衡
服务自动注册及发现

安装ZooKeeper 服务注册中心

ZooKeeper 是一个分布式的，开放源码的分布式应用程序协调服务。它是一个为分布式应用提供一致性服务的软件，提供的功能包括：配置维护、域名服务、分布式同步、组服务等。

在这就不详细写安装ZooKeeper 的步骤了，不会的安装的亲可以问度娘哟~

项目结构

SpringBootDubbo-Server

springboot-dubbo-client

SpringBootDubbo-Server代码实现

1、pom.xml文件

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>SpringBootDubbo-Server</groupId><artifactId>springboot-dubbo-client</artifactId><version>0.0.1-SNAPSHOT</version><!-- SpringBoot父类依赖引用 --><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.5.2.RELEASE</version></parent><properties><dubbo-spring-boot>1.0.0</dubbo-spring-boot></properties><dependencies><!-- Spring Boot Dubbo 依赖 --><dependency><groupId>io.dubbo.springboot</groupId><artifactId>spring-boot-starter-dubbo</artifactId><version>${dubbo-spring-boot}</version></dependency><!-- SpringBoot web 组件 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies>
</project>

2、application.properties

## Dubbo 服务提供者配置
spring.dubbo.application.name=provider
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.scan=com.fit

3、User.java

public class User implements Serializable{/*** */private static final long serialVersionUID = 1L;private String id;private String name;public User(String id, String name) {this.id = id;this.name = name;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}

4、Service层

public interface UserDubboService {public User getUser();
}@Service
public class UserDubboServiceImpl implements UserDubboService {public User getUser() {// TODO Auto-generated method stubUser user = new User("1","zlzhaoe");return user;}}

5、ServerApp.java

@SpringBootApplication
public class ServerApp {/*** @param args*/public static void main(String[] args) {// TODO Auto-generated method stubSpringApplication.run(ServerApp.class, args);}}

springboot-dubbo-client代码实现

1、pom.xml文件

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>SpringBootDubbo-Server</groupId><artifactId>springboot-dubbo-client</artifactId><version>0.0.1-SNAPSHOT</version><!-- SpringBoot父类依赖引用 --><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.5.2.RELEASE</version></parent><properties><dubbo-spring-boot>1.0.0</dubbo-spring-boot></properties><dependencies><!-- Spring Boot Dubbo 依赖 --><dependency><groupId>io.dubbo.springboot</groupId><artifactId>spring-boot-starter-dubbo</artifactId><version>${dubbo-spring-boot}</version></dependency><!-- SpringBoot web 组件 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies>
</project>

2、application.properties

## 端口号
server.port=8081
## Dubbo
spring.dubbo.application.name=consumer
spring.dubbo.registry.address=zookeeper://127.0.0.1:2181
spring.dubbo.scan=com.fit

3、User.java

public class User implements Serializable{/*** */private static final long serialVersionUID = 1L;private String id;private String name;public User(String id, String name) {this.id = id;this.name = name;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}

4、service层

public interface UserDubboService {public User getUser();
}

5、Controller层

@RestController
public class UserController {@Referenceprivate UserDubboService userDubboService;@RequestMapping(value ="getUser")public User getUser() {// TODO Auto-generated method stubUser user = userDubboService.getUser();return user;}
}

6、启动SpringBootDubbo-Server，springboot-dubbo-client运行访问http://localhost:8081/getUser
