Struts2---->fielderror显示处理
一、去掉fielderror显示中前面的圈的方法
theme都存在jar包中template文件夹下。
1、覆盖所应用主题中的的fielderror的那个ftl文件
新建/src/template/simple/fielderror.ftl

<span>${eEachValue}</span>
</#list><#t/>
</#list><#t/>
</#if><#t/>
</#if><#t/>
</#if><#t/>
2、css控制
<?xml version="1.0" encoding="GB18030" ?>
<%@ page language="java" contentType="text/html; charset=GB18030"
pageEncoding="GB18030"%>
<%@ taglib uri="/struts-tags" prefix="s" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB18030" />
<title>theme学习</title>
<style type="text/css">
.formFieldError {
font-family: verdana, arial, helvetica, sans-serif;
font-size: 12px;
color: #FF3300;
vertical-align: bottom;
}
.formFieldError ul {
/*list-style-type: none*/
margin: 0px;
padding: 3px;
vertical-align: middle;
}
.formFieldError ul li{
list-style-type: none
}
</style>
</head>
<body>
用CSS控制显示
<ol>
<li>
<s:form >
<div class="formFieldError">
<s:fielderror />
</div>
<s:textfield name='aaa'></s:textfield>
</s:form>
</li>
</ol>
</body>
</html>
3、定义自己的主题，并且在配置文件设置为默认
将 <constant name="struts.ui.theme" value="simple" />改为<constant name="struts.ui.theme" value="mytheme" />
自己定义的mytheme和simple一模一样，只不过是将fielderror.ftl改成第一种方法中的。
推荐：所有的主题定义为simple，把fielderror特殊处理，自己控制其他标签的展现。
