接上文

--------------------------------------------------------------------------------------------------------------------------------

步骤:

1、创建maven工程:

pom.xml文件内容同上文,只不过将tomcat的端口号改下;

2、编写web.xml文件:

同上文

3、将上文创建的interface,连同他的包一同复制在我们的src/main/java下

4、创建class作为我们的handler

说明:1、@RestController注解相当于@Controller和@ResponseBody的合体

         2、@Reference注解为alibaba的,是远程调用标签

package com.aynu.dubbo.handler; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.servlet.ModelAndView; import com.alibaba.dubbo.config.annotation.Reference; import com.aynu.dubbo.service.IDubboTest; @RestController @RequestMapping("/test") public class DubboHanlder { @Reference private IDubboTest service; @RequestMapping("/dubbo.do") public void dubbo() { String DUBBO = service.sayHello("DUBBO"); System.out.println(DUBBO); } }

5、创建spring-handler.xml文件:

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <!-- 注册mvc解析器 --> <mvc:annotation-driven/> <!-- 为当前应用取名字,可以随意,建议为项目名 --> <dubbo:application name="dubbo_sonmer"/> <!-- 连接远程zookeeper --> <dubbo:registry address="zookeeper://192.168.146.128:2181"/> <!-- dubbo包扫描器 --> <dubbo:annotation package="com.aynu.dubbo.handler"/> </beans>

6、运行(前提是提供方已经运行):

打开管控台,在消费者中可见内容:
