Spring Boot Integrated Dubbo

Spring-boot-start-dubbo

Spring-boot-start-dubbo allows you to develop Dubbo programs in a Spring-boot way. Makes Dubbo development so simple.

How to use 1. Clone code (optional, has been published to the central warehouse, can directly rely on a stable version of the Central warehouse)

git clone [email protected]:teaey/spring-boot-starter-dubbo.git

2. Compile and install (optional)

cd spring-boot-starter-dubbomvn clean install

3. Modify MAVEN configuration file (refer to sample Spring-boot-starter-dubbo-sample)

• The pom.xml of the Spring boot project adds the parent:

<parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>1.3.6.RELEASE</version></parent>

• Add the following dependencies in the pom.xml of the Spring Boot project:

Depending on the actual situation depends on the latest version

 <dependency>     <groupId>io.dubbo.springboot</groupId>     <artifactId>spring-boot-starter-dubbo</artifactId>     <version>1.0.0</version> </dependency>

• The Maven plugin is used to package the executable Uber-jar file and add the following plug-in (this must be loaded in the POM that needs to be packaged as a jar Mudule)

<plugin>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-maven-plugin</artifactId>    <version>1.3.6.RELEASE</version></plugin>

4. Publishing services

Service Interface:

package cn.teaey.sprintboot.test;public interface EchoService {    String echo(String str);}

In Application.properties Add the Dubbo version information and the client timeout information, as follows:

spring.dubbo.application.name=providerspring.dubbo.registry.address=zookeeper://192.168.99.100:32770spring.dubbo.protocol.name=dubbospring.dubbo.protocol.port=20880spring.dubbo.scan=cn.teaey.sprintboot.test

Add Spring.dubbo.scan to Application.properties in spring application to support Dubbo Service Publishing, where scan represents the package directory to be scanned

• Spring Boot Boot

package cn.teaey.sprintboot.test;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class Server {    public static void main(String[] args) {        SpringApplication.run(Server.class, args);    }}

• To write your Dubbo service, simply add @Service to the service implementation you want to publish, as follows

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. Consumer Dubbo Services

• In Application.properties Add the Dubbo version information and the client timeout information, as follows:

spring.dubbo.application.name=consumerspring.dubbo.registry.address=zookeeper://192.168.99.100:32770spring.dubbo.scan=cn.teaey.sprintboot.test

Add Spring.dubbo.scan to Application.properties in spring application to support Dubbo Service Publishing, where scan represents the package directory to be scanned

• Spring Boot Boot

package cn.teaey.sprintboot.test;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ConfigurableApplicationContext;@SpringBootApplicationpublic 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"));    }}

• To reference the Dubbo service, simply add @Reference to the service implementation you want to publish, as follows:

package cn.teaey.sprintboot.test;import com.alibaba.dubbo.config.annotation.Reference;import org.springframework.stereotype.Component;@Componentpublic class AbcService {    @Reference(version = "1.0.0")    public EchoService echoService;}

6. Packaging

Server or client startup can be performed directly

Can be packaged into an executable Uber-jar file via the MVN clean package
