我的配置如下：
（1）、web.xml

 <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
         xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 
         id="WebApp_ID" version="3.1">

  <!-- B:配置中文编码问题的过滤器 -->
    <filter>

    </filter>
    <filter-mapping>
