SSM框架搭建看这篇http://blog.csdn.net/zhshulin/article/details/37956105

当需要把控制类升级为RESTController时，在spring-mvc.xml只需添加一句<mvc:annotation-driven />

<?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:p="http://www.springframework.org/schema/p"      xmlns:context="http://www.springframework.org/schema/context"      xmlns:mvc="http://www.springframework.org/schema/mvc"      xsi:schemaLocation="http://www.springframework.org/schema/beans                            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd                            http://www.springframework.org/schema/context                            http://www.springframework.org/schema/context/spring-context-3.1.xsd                            http://www.springframework.org/schema/mvc                            http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">      <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->      <context:component-scan base-package="com.luoka.weixin1545.controller" />       <!-- 添加注解驱动 enable-matrix-variables="true" --><mvc:annotation-driven  />     <!--避免IE执行AJAX时，返回JSON出现下载文件 com.luoka.weixin1545.controller -->     <bean id="mappingJacksonHttpMessageConverter"          class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">          <property name="supportedMediaTypes">              <list>                  <value>text/html;charset=UTF-8</value>              </list>         </property>      </bean>      <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->      <bean          class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">          <property name="messageConverters">              <list>                  <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 -->              </list>          </property>      </bean>      <!-- 定义跳转的文件的前后缀 ，视图模式配置-->      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">          <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->          <property name="prefix" value="/WEB-INF/jsp/" />          <property name="suffix" value=".jsp" />      </bean>         <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->      <bean id="multipartResolver"            class="org.springframework.web.multipart.commons.CommonsMultipartResolver">            <!-- 默认编码 -->          <property name="defaultEncoding" value="utf-8" />            <!-- 文件大小最大值 -->          <property name="maxUploadSize" value="10485760000" />            <!-- 内存中的最大值 -->          <property name="maxInMemorySize" value="40960" />        </bean> </beans>

java原来控制类

@Controller  @RequestMapping("user")public class userController {    @Resource      private IUserService userService;            @RequestMapping("/showUser")     public String toIndex(HttpServletRequest request,Model model){          int userId = Integer.parseInt(request.getParameter("id"));          User user = this.userService.getUserById(userId);          model.addAttribute("user", user);          return "showUser";      } }

控制类升级RESTAPI后

@RestController@RequestMapping("/user")public class userController {  @Resource      private IUserService userService;            @RequestMapping("/{id}")    public User GETUSER(@PathVariable Integer id){           User user = this.userService.getUserById(id);           return user;    } }
