jsp中的include静态页面出现乱码问题

在当前应用系统的web.xml里加入jsp-config代码：

<web-app 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" version="2.4">
<jsp-config>
<jsp-property-group>
<description>
Special property group for JSP Configuration JSP example.
</description>
<display-name>JSPConfiguration</display-name>
<url-pattern>*.jsp</url-pattern>
<el-ignored>true</el-ignored>
<page-encoding>GB2312</page-encoding>
<scripting-invalid>false</scripting-invalid>
<include-prelude></include-prelude>
<include-coda></include-coda>

</description>
<display-name>JSPConfiguration</display-name>
<url-pattern>*.html</url-pattern>
<el-ignored>true</el-ignored>
<page-encoding>GB2312</page-encoding>
<scripting-invalid>false</scripting-invalid>
<include-prelude></include-prelude>
<include-coda></include-coda>
</jsp-property-group>
</jsp-config>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
</welcome-file-list>

... ...

</webapp>

说明：<jsp-config>里的定义，就是通知当前应用服务器，当前应用系统下，所有的 .jsp, .html 文件，若是没有定义contentType="text/html;charset=gb2312" 时，就会采用预设的 "GB2312" 字符集去处理，如此，就不须要在每个 include 的档案第一行加上 contentType="text/html;charset=gb2312" 了。

注：

＜jsp-config＞标签使用详解

<jsp-config> 包括<taglib> 和<jsp-property-group> 两个子元素。

其中<taglib>元素在JSP 1.2时就已经存在；而<jsp-property-group>是JSP 2.0 新增的元素。
<jsp-property-group>元素主要有八个子元素，它们分别为：

1.<description>：设定的说明；
2.<display-name>：设定名称；
3.<url-pattern>：设定值所影响的范围，如：/CH2 或 /*.jsp；
4.<el-ignored>：若为true，表示不支持EL 语法；
5.<scripting-invalid>：若为true，表示不支持<% scripting %>语法；
6.<page-encoding>：设定JSP 网页的编码；
7.<include-prelude>：设置JSP 网页的抬头，扩展名为.jspf；
8.<include-coda>：设置JSP 网页的结尾，扩展名为.jspf。
