HTTP Status 405 - JSPs only permit GET POST or HEAD

這兩天在看springmvc視頻並且手動敲代碼時遇見了如下問題，以下是我的代碼截圖：

package com.wildpointer.springmvc.handlers;

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;

@Controller
public class HelloWorld {
	
	private static final String SUCCESS = "success";
	
	
	@RequestMapping(value="/testRest/{id}",method=RequestMethod.PUT)
	public String testRestPut(@PathVariable Integer id){
		System.out.println("testRest Put: "+id);
		return SUCCESS;
	}
	
	
	@RequestMapping(value="/testRest/{id}",method=RequestMethod.DELETE)
	public String testRestDelete(@PathVariable Integer id){
		System.out.println("testRest Delete: "+id);
		return SUCCESS;
	}
	
	@RequestMapping(value="/testRest",method=RequestMethod.POST)
	public String testRest(){
		System.out.println("testRest POST: ");
		return SUCCESS;
	}
	
	@RequestMapping(value="/testRest/{id}",method=RequestMethod.GET)
	public String testRest(@PathVariable Integer id){
		System.out.println("testRest GET: "+id);
		return SUCCESS;
	}
	
	@RequestMapping("/testPathVariable/{id}")
	public String testPathVariable(@PathVariable("id") Integer id ){
		System.out.println("testPathVariable: "+ id);
		return SUCCESS;
	}
	
	@RequestMapping(value="/helloworld")
	public String hello(){
		System.out.println("helloWorld");
		return "success";
	}
}

	<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>




	<servlet>
		<servlet-name>springDispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>


	<servlet-mapping>
		<servlet-name>springDispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

解決辦法：

加入@Responsebody註解即可

@ResponseBody
	@RequestMapping(value="/testRest/{id}",method=RequestMethod.DELETE)
	public String testRestDelete(@PathVariable Integer id){
		System.out.println("testRest Delete: "+id);
		return SUCCESS;
	}
