RESTFul风格的SringMVC

@Controller
@RequestMapping("/rest")
public class RestController {
    @RequestMapping(value="/user/{id}",method=RequestMethod.GET)
    public String get(@PathVariable("id") Integer id){
        System.out.println("get"+id);
        return "/hello";
    }
     
    @RequestMapping(value="/user/{id}",method=RequestMethod.POST)
    public String post(@PathVariable("id") Integer id){
        System.out.println("post"+id);
        return "/hello";
    }
     
    @RequestMapping(value="/user/{id}",method=RequestMethod.PUT)
    public String put(@PathVariable("id") Integer id){
        System.out.println("put"+id);
        return "/hello";
    }
     
    @RequestMapping(value="/user/{id}",method=RequestMethod.DELETE)
    public String delete(@PathVariable("id") Integer id){
        System.out.println("delete"+id);
        return "/hello";
    }
     
}

2.form表单发送put和delete请求

在web.xml中配置

<!-- configure the HiddenHttpMethodFilter,convert the post method to put or delete -->
<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>

<form action="rest/user/1" method="post">
    <input type="hidden" name="_method" value="PUT">
    <input type="submit" value="put">
</form>
 
<form action="rest/user/1" method="post">
    <input type="submit" value="post">
</form>
 
<form action="rest/user/1" method="get">
    <input type="submit" value="get">
</form>
 
<form action="rest/user/1" method="post">
    <input type="hidden" name="_method" value="DELETE">
    <input type="submit" value="delete">
</form>
