Struts中在前台中通过<s: fielderror />拿到action中addFieldError("fielderror.test", "wrong!")添加的错误信息是,默认情况下是带了<ul><li>...</li></ul>格式的。这个给自己设定错误信息的表现带来不便,三种解决方法:1. 在前台jsp页面中加入css控制 .formFieldError ul li{list-style-type: none } <div class="formFieldError"> <s:fielderror /></div> 2. 在struts.xml中配置配置如下常量时,默认的ui主题会到struts-core的jar包中找对应的配置<constant name="struts.ui.theme" value="simple" /> 这个配置截图: 若value=simple,则找template.simple中配置,这里的value还可以取值xhtml,css_xhtml,xhtml,那么对应的就找对应的template中的ui配置,其中有一个文件为/template/simple/fielderror.ftl。只要自己在src下定义一个相同名称的配置,然后删除其中的加格式的部分就可以了。 删除后如下,直接拷贝到fielderror.ftl中<#-- /* * $Id: fielderror.ftl 722375 2008-12-02 05:19:57Z wesw $ * * Licensed to the Apache Software Foundation (ASF) under one * or more contributor license agreements.
