html:errors注意点:
1.<html:errors/>
2.saveErrors()
3.资源文件
- html:errors标签使用(需配置资源文件ApplicationResources.properties)
- 读取资源文件的方法 ApplicationResources.properties
- java读取ApplicationResources.properties资源文件
- 让Struts中的资源文件(ApplicationResources.properties)支持中文
- java读取ApplicationResources.properties资源文件 (转贴)
