Tomcat发生错误时跳转到错误页面
注意 ：5.0下操作需要删除掉注释语句，不然报错，原因未知
一、修改 tomcat 的配置文件
修改 tomcat 的配置文件，当页面发生错误时跳转到指定的页面，在 tomcat 中 web.xml 文件中添加如下内容：
<!-- 400错误 -->
<error-page>
<error-code>400</error-code>
<location>/error.html</location>
</error-page>
<!-- 404 页面不存在错误 -->
<error-page>
<error-code>404</error-code>
<location>/error.html</location>
</error-page>
<!-- 500 服务器内部错误 -->
<error-page>
<error-code>500</error-code>
<location>/error.html</location>
</error-page>
<!-- java.lang.Exception异常错误,依据这个标记可定义多个类似错误提示 -->
<error-page>
<exception-type>java.lang.Exception</exception-type>
<location>/error.html</location>
</error-page>
<!-- java.lang.NullPointerException异常错误,依据这个标记可定义多个类似错误提示 -->
<error-page>
<exception-type>java.lang.NullPointerException</exception-type>
<location>/error.html</location>
</error-page>

二、编写 error.html 界面
error.html 界面需要放在 webapps 的 ROOT 目录中，结构如下：
404文件夹内容
error.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<title>网页访问不了</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="404/error_all.css?t=201303212934">
</head>
<body class="error-404">
<div id="doc_main">
<section class="bd clearfix">
<div class="module-error">
<div class="error-main clearfix">
<div class="label"></div>
<div class="info">
<h3 class="title">啊哦，你所访问的页面不存在了，可能是炸了</h3>
<div class="reason">
<p>可能的原因：</p>
<p>1.手抖打错了。</p>
<p>2.链接过了保质期。</p>
</div>
<div class="oper">
<p><a href="javascript:history.go(-1);">返回上一级页面></a></p>
</div>
</div>
</div>
</div>
</section>
</div>
</body></html>
