Spring Cloud与Dubbo共存方案.zip

#spring-boot-start-dubbo ## 如何使用 ### 1. clone 代码 ``` git clone git@github.com:teaey/spring-boot-starter-dubbo.git ``` ### 2. 编译安装 ``` cd spring-boot-starter-dubbo mvn clean install ``` ### 3. 修改maven配置文件(可以参考样例[spring-boot-starter-dubbo-sample](https://github.com/teaey/spring-boot-starter-dubbo-sample)) * 在Spring Boot项目的pom.xml增加parent: ``` <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.3.6.RELEASE</version> </parent> ``` * 在Spring Boot项目的pom.xml中添加以下依赖: ``` <dependency> <groupId>io.dubbo.springboot</groupId> <artifactId>spring-boot-starter-dubbo</artifactId> <version>1.0.0-SNAPSHOT</version> </dependency> ``` * maven插件用于打包成可执行的uber-jar文件,添加以下插件(这里一定要加载需要打包成jar的mudule的pom中) ``` <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>1.3.6.RELEASE</version> </plugin> ``` ### 4. 发布服务 服务接口: ``` package cn.teaey.sprintboot.test; public interface EchoService { String echo(String str); } ``` 在application.properties添加Dubbo的版本信息和客户端超时信息,如下: ``` spring.dubbo.application.name=provider spring.dubbo.registry.address=zookeeper://192.168.99.100:32770 spring.dubbo.protocol.name=dubbo spring.dubbo.protocol.port=20880 spring.dubbo.scan=cn.teaey.sprintboot.test ``` 在Spring Application的application.properties中添加spring.dubbo.scan即可支持Dubbo服务发布,其中scan表示要扫描的package目录 * spring boot启动 ``` package cn.teaey.sprintboot.test; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class Server { public static void main(String[] args) { SpringApplication.run(Server.class, args); } } ``` * 编写你的Dubbo服务,只需要添加要发布的服务实现上添加 @Service ,如下 ``` package cn.teaey.sprintboot.test; import com.alibaba.dubbo.config.annotation.Service; @Service(version = "1.0.0") public class EchoServerImpl implements EchoService { public String echo(String str) { System.out.println(str); return str; } } ``` ### 5. 消费Dubbo服务 * 在application.properties添加Dubbo的版本信息和客户端超时信息,如下: ``` spring.dubbo.application.name=consumer spring.dubbo.registry.address=zookeeper://192.168.99.100:32770 spring.dubbo.scan=cn.teaey.sprintboot.test ``` 在Spring Application的application.properties中添加spring.dubbo.scan即可支持Dubbo服务发布,其中scan表示要扫描的package目录 * spring boot启动 ``` package cn.teaey.sprintboot.test; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.ConfigurableApplicationContext; @SpringBootApplication public class Client { public static void main(String[] args) { ConfigurableApplicationContext run = SpringApplication.run(Client.class, args); AbcService bean = run.getBean(AbcService.class); System.out.println(bean.echoService.echo("abccc")); } } ``` * 引用Dubbo服务,只需要添加要发布的服务实现上添加 @Reference ,如下: ``` package cn.teaey.sprintboot.test; import com.alibaba.dubbo.config.annotation.Reference; import org.springframework.stereotype.Component; @Component public class AbcService { @Reference(version = "1.0.0") public EchoService echoService; } ``` ### 6. 打包 > 可以直接执行Server或者Client启动 > 可以通过mvn clean package 打包成可执行的uber-jar文件
