jsp关于include html、jsp等文件出现乱码问题的解决方案

一般来说使用jsp标签<jsp:include>引入一个jsp文件：

①可以在被引入的jsp中加入：<%@ page contentType="text/html;charset=UTF-8" language="java" %>

②在当前项目的web.xml中加入：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 
<jsp-config>
<jsp-property-group>
<description>jsp encoding example</description>
<display-name>JSPConfiguration</display-name>
<url-pattern>*.jsp</url-pattern>
<el-ignored>false</el-ignored>
<page-encoding>UTF-8</page-encoding>
<scripting-invalid>false</scripting-invalid>
</jsp-property-group>

<jsp-property-group>
<display-name>JSPConfiguration</display-name>
<url-pattern>*.html</url-pattern>
<el-ignored>false</el-ignored>
<page-encoding>UTF-8</page-encoding>
<scripting-invalid>false</scripting-invalid>
</jsp-property-group>

<jsp-property-group>
<display-name>JSPConfiguration</display-name>
<url-pattern>*.ftl</url-pattern>
<el-ignored>false</el-ignored>
<page-encoding>UTF-8</page-encoding>
<scripting-invalid>false</scripting-invalid>
</jsp-property-group>
</jsp-config>

</web-app>

提示：在有些编译器中可能会提示错误，但是加入后仍可以运行，并且没有出现什么致命错误。
