十二、RESTFul风格的SringMVC

1.RestController

复制代码
@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";
    }
    
}
复制代码

2.form表单发送put和delete请求

在web.xml中配置

复制代码
  <!-- 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>
复制代码

在前台可以用以下代码产生请求

复制代码
    <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>
package test.SpringMVC;
//D:\Indigo_workspace2\HiSpringMVC\src\test\SpringMVC\RestController.java
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ModelAttribute;

@Controller
@RequestMapping("/rest")
public class RestController {

    //http://localhost:8080/HiSpringMVC/rest/hello
    @RequestMapping("/hello")
    public String hello(){
        System.out.println("hello");
        return "hello";
    }
    
    @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";
    }
       
   
    
}
