struts2 服务器端验证 和 项目路径问题
struts2 服务器端验证
<validators>
<field name="customer">
<field-validator type="visitor">
<param name = "context">customer</param>
<param name = "appendPrefix">true</param>
<message></message>
</field-validator>
</field>
classname + context + validation.xml 解决 复杂对象输入验证问题

项目路径:
String path = ServletActionContext.getServletContext().getRealPath("/");
class根路径:
String path = FileUtil.class.getResource("/").getPath();
