SpringMVC 通过RESTFUL风格进行CRUD

jsp页面：

   <form action="${pageContext.request.contextPath}/login/checkeRestFull.do" method="post">     <input type="submit" value="测试post">    </form>      <form action="${pageContext.request.contextPath}/login/checkeRestFull/1.do" method="get">     <input type="submit" value="测试get">    </form> 

controller页面：

@Controller@RequestMapping("/login")//@SessionAttributes(value="username",types=String.class)public class LoginController {@RequestMapping(value="/checkeRestFull",method=RequestMethod.POST)  //增public String testPost(){System.out.println("this is testPost");return "users/ok";}@RequestMapping(value="/checkeRestFull/{id}",method=RequestMethod.GET)   //查public String testGet(@PathVariable(value="id")int id) {System.out.println("this is testGet and id="+id);return "users/ok";}

修改、删除稍加复杂：

需在web.xml中配置过滤器：

    <filter>      <filter-name>hiddenHttpMethodFilter</filter-name>      <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>    </filter>    <filter-mapping>      <filter-name>hiddenHttpMethodFilter</filter-name>      <url-pattern>/*</url-pattern>    </filter-mapping>   

另外在表单域中添加隐藏域：

   <form action="${pageContext.request.contextPath}/login/checkeRestFull/1.do" method="post">     <input type="hidden" name="_method" value="put">     <input type="submit" value="测试put">   </form>    <form action="${pageContext.request.contextPath}/login/checkeRestFull/1.do" method="post">     <input type="hidden" name="_method" value="delete">     <input type="submit" value="测试delete">   </form>   

controller代码：

@RequestMapping(value="/checkeRestFull/{id}",method=RequestMethod.PUT)  //修改public String testPut(@PathVariable(value="id") int id){System.out.println("this is testPut id="+id);return "users/ok";}@RequestMapping(value="/checkeRestFull/{id}",method=RequestMethod.DELETE)  //删除public String testDelete(@PathVariable(value="id") int id) {System.out.println("this is testDelete id="+id);return "users/ok";}
