SpringBoot整合Dubbo&Zookeeper

1. 安装 Zookeeper 环境

2. 服务提供者

2.1 pom依赖

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

        <!-- Spring Boot Test 依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!--spring data jpa -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <!--mysql-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.8-dmr</version>
            <scope>compile</scope>
        </dependency>
        <!--dubbo 依赖-->
        <dependency>
            <groupId>io.dubbo.springboot</groupId>
            <artifactId>spring-boot-starter-dubbo</artifactId>
        </dependency>
        <!--junit 测试工具-->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
        <dependency>
            <groupId>com.tyut</groupId>
            <artifactId>ip-common</artifactId>
            <version>${ip.version}</version>
        </dependency>

    </dependencies>

2.2. Service填写

大概给下项目架构:

为了方便，我用的springboot data jpa做持久性框架。如果不会jpa，请先看我springboot jpa整合。

SchoolRepository .java

/**
 * Created by Fant.J.
 */
@Repository
public interface SchoolRepository extends JpaRepository<School,Integer> {

}

SchoolService.java 略(一个正常的借口)
实现类SchoolServiceImpl .java核心代码

@Service(version = "2.0.1")
public class SchoolServiceImpl implements SchoolService {
    @Autowired
    private SchoolRepository schoolRepository;

这里的@Service注解是dubbo的注解，不是springframework下的注解。该注解就是向zk注册服务。

2.3. application.properties

server.port=9002

## Dubbo 服务提供者配置

spring.dubbo.application.name=school-server
spring.dubbo.registry.address=zookeeper://xxx.xxx.xxx.xxx:2181
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20882
spring.dubbo.scan=com.xxx.school.service

spring.datasource.url=jdbc:mysql://xxxxxxxxxx
spring.datasource.username=xxxx
spring.datasource.password=xxxx
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

3. 服务消费

为了和服务提供者解耦，我们需要把Service接口类单独拿出来放到client模块里，这里不贴详细代码了。

3.1 pom.xml

这里略，根据controller类里的需要来填充相关依赖

3.2 SchoolController

@RestController
@RequestMapping("/sch")
public class SchoolController {

    @Reference(version = "2.0.1")
    private SchoolService schoolService;

    @RequestMapping("/all")
    public ServerResponse getAll(){
        return schoolService.selectAll();
    }
}

注意与@Service注解的version属性值一一对应。

3.3 application.properties

## Dubbo 服务消费者配置
spring.dubbo.application.name=xxx
spring.dubbo.registry.address=zookeeper://xxxx.xxx.xxx.xxx
spring.dubbo.scan=com.xxx.web.controller
