Answer 1

 Caught OgnlException while setting property 'trim' on type 'com.opensymphony.xwork2.validator.validators.RequiredFieldValidator'.
ognl.NoSuchPropertyException: com.opensymphony.xwork2.validator.validators.RequiredFieldValidator.trim
没有找到trim这个属性，你在哪个地方用到了。自己检查看看。

Answer 2

看到提示Ognl，我建议楼主看看导入的Struts2核心包是否正确

Answer 3

我也出现了这个问题，最后发现是我在age（int）下也写了<param name="trim">true</param> ，去掉后就不报警告了
