Spring4.3.x解决Delete,Put请求参数绑定失败

1. 新增HiddenHttpMethodFilter过滤器处理DELETE,PUT请求

web.xml新增HiddenHttpMethodFilter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>
    <servlet-name>springMVC3</servlet-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

SpringMVC请求:

	@RequestMapping(value="/test",method=RequestMethod.DELETE)
	public String deleteprescription(String content) {
		return content;
	}

注意baseUrl默认: http://域名:端口/项目名/
前端代码:

	$.ajax({
      url: ${baseUrl} +'test',
      data:{
        _method:"DELETE",
        content:"helloword"
      },
      method:'POST',
      success:function(res){
      	console.log(res)
      }

2. 直接使用RestFul风格

SpringMVC请求：

	@RequestMapping(value="/test/{conetent}",method=RequestMethod.DELETE)
	public String deleteprescription(@PathVariable("content") String content) {
		return content;
	}

前端代码:

	$.ajax({
	      url: ${baseUrl} +'test',
	      data:{
	        content:"helloword"
	      },
	      method:'DELETE',
	      success:function(res){
	      	console.log(res)
	      }
