web项目调用dubbo的provider

上一篇文章中消费者是在Maven项目中调用，接下来，我将使用web项目来调用提供者的接口

首先新建一个web工程（如何创建Maven的web项目自行上网百度），项目结构如下：

首先来看下pom.xml（可以拷贝上一篇文章中消费者的）

MyController.java

package com.tan.controller;import javax.annotation.Resource;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.servlet.ModelAndView;import com.cl.user.servicei.UserService;@Controllerpublic class MyController {@Resource(name="userService")private UserService userService;@RequestMapping(method=RequestMethod.GET, value="/test/{id}",produces="text/plain;charset=UTF-8")@ResponseBodypublic String say(@PathVariable String id){return userService.sayHello("4");}@RequestMapping(method=RequestMethod.GET, value="/test1/{id}",produces="text/plain;charset=UTF-8")@ResponseBodypublic String test(@PathVariable String id){return userService.test(2,3);}@RequestMapping(method=RequestMethod.GET, value="/test2",produces="text/plain;charset=UTF-8")@ResponseBodypublic String test2(){return userService.test2(); }@RequestMapping("login.do")@ResponseBody        public ModelAndView login(String username,String password){String result=userService.login(username, password);System.out.println("result===>"+result);                return new ModelAndView(result,"username",username);    }    }

接下去在将项目部署在Tomcat下，启动，打开浏览器输入网址：http://localhost:8080/tan-springmvc-book/test/1   就可以看到provider返回的数据：

provider接口实现：

这里输入的网址还可以根据MyController中不同方法进行不同调用，如还可以访问：http://localhost:8080/tan-springmvc-book/test1/1  

好了 ，本次就讲到这里，这篇是基于上一篇的改造，比较简单，所以就直接贴出代码，具体可以下载源码在研究研究
