使用springmvc时报错JSPs only permit GET POST or HEAD

两个地方需要注意：
第一处在web.xml文件中不要忘记配置

<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>

第二处是在方法开头加上注解@ResponseBody，代码如下所示

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

然后就成功了。
