如何解决ajax的delete、put方法接收不到参数的问题？

通过修改配置文件来实现Put和Delete请求的参数传递的问题

在web.xml中添加如下代码：

<filter>
    <filter-name>HttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>HttpMethodFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <!-- 备注，这边的名称必须和配置'springmvc'的servlet名称一样 -->
    <servlet-name>spring</servlet-name>
  </filter-mapping>

js中代码：如果是删除的话，就将put改为delete
