springmvc中有一个filter, 可以把普通请求转化为规定行使的请求
  1. 配置:
  1. <filter>
  2.     <filter-name>hiddenHttpMethodFilter</filter-name>
  3.     <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  4. </filter>
  5. <filter-mapping>
  6.     <filter-name>hiddenHttpMethodFilter</filter-name>
  7.     <url-pattern>/*</url-pattern>
  8. </filter-mapping>
  1. 使用
<form action="" method="post">
    <input type="hidden" name="_method" value="method" />
</form>
  1. 高版本Tomcat 405错误解决(Tomcat8及以上)
<%@ page contentType="text/html;charset=UTF-8" language="java"
    isErrorPage="true" %>
