dubbox入门
dubbox定义:
dubbox和dubbo差不多,dubbox由当当网维护,使用http协议和rest编码风格
在maven仓库中添加Doubbox依赖
因为:Maven不支持dubbox直接从中央仓库导入
- 我们需要一个dubbox-dubbox.zip包(从github上拿)
① 博客操作指南:
② https://blog.csdn.net/try_and_do/article/details/83383861
2.解压后需要将文件打成jar包
① 命令:Jar -cf 文件.jar 文件
3.将jar文件导成maven库的依赖
(将alibaba文件(放入maven库中)替换E:\Maven项目管理模型\maven_re\com\alibaba)
编码
一,导入dubbox依赖(默认从maven库中找dubbox依赖)
<dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.8.4</version> </dependency> <!-- 添加zk客户端依赖 --> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> <version>0.1</version> </dependency> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jaxrs</artifactId> <version>3.0.7.Final</version> </dependency> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-client</artifactId> <version>3.0.7.Final</version> </dependency> <dependency> <groupId>javax.validation</groupId> <artifactId>validation-api</artifactId> <version>1.0.0.GA</version> </dependency> <!-- 如果要使用json序列化 --> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jackson-provider</artifactId> <version>3.0.7.Final</version> </dependency> <!-- 如果要使用xml序列化 --> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jaxb-provider</artifactId> <version>3.0.7.Final</version> </dependency> <!-- 如果要使用netty server --> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-netty</artifactId> <version>3.0.7.Final</version> </dependency> <!-- 如果要使用Sun HTTP server --> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jdk-http</artifactId> <version>3.0.7.Final</version> </dependency> <!-- 如果要使用tomcat server --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-core</artifactId> <version>8.0.11</version> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-logging-juli</artifactId> <version>8.0.11</version> </dependency> <dependency> <groupId>com.esotericsoftware.kryo</groupId> <artifactId>kryo</artifactId> <version>2.24.0</version> </dependency> <dependency> <groupId>de.javakaffee</groupId> <artifactId>kryo-serializers</artifactId> <version>0.26</version> </dependency> <dependency> <groupId>de.ruedigermoeller</groupId> <artifactId>fst</artifactId> <version>1.55</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.3.3</version> </dependency> <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty</artifactId> <version>7.0.0.pre5</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <scope>test</scope> </dependency>
1.服务者
service接口
@Path("/dosomeService") public interface DoSomeService { @Path("/doSome/{userName}") @GET @Consumes({ MediaType.APPLICATION_JSON }) public String doSome(@PathParam("userName") String userName); }
service实现
public class DoSomeServiceImpl implements DoSomeService { @Override public String doSome(String userName) { System.out.println("dubbox 发布的DoSomeService 服务 doSome方法\t"+userName); return "bubbox"; } }

Apptest
public class AppTest { public static void main(String[] args) throws IOException { //加载配置文件:配置文件中通过SPring将Dubbo服务注册到注册中心当中去 ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext-provider.xml"); System.out.println("dubbox服务已经发布!!!!!"); //阻塞 System.in.read(); } }
2.消费者
applicationContext-consumer.xml

testControll
public class testControll { public static void main(String[] args) { ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext-consumer.xml"); doSomeService doSomeService = (doSomeService)ctx.getBean("doSomeService"); doSomeService.doSome("李四"); } }
