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。
