Answer 4

com.gulebao.posts.entity.Threads这个类有这个方法是setTPrice(Integer arg),你的validation.xml应该将此字段的匹配类型应该为integer，而不是string

Answer 5

<field name="threads.TPrice">
<field-validator type="int">
<message>内容不能为空</message>
</field-validator>

<field-validator type="regex">
<param name="expression">^[0-9a-z_A-Z\u4e00-\u9fa5]+$</param>
<message>含有非法的字符，请重新输入</message>
</field-validator>
</field>
我改了，可是，还是报错···

Answer 7

直接写js验证算啦
struts的验证框架用的不太爽

Answer 8

struts2自带的类型转换器在页面也发出了类型转换错误的信息，可是，为什么控制台还要报错啊···天啊

Answer 9

楼主,问题很明显,你的验证框架没有配对,你再好好看看struts2的验证框架怎么配的

Answer 10

可是在jsp页面，struts2自带的类型转换验证器打出了类型转换异常的信息啊，Invalid field value for field "threads.TPrice，

Answer 11

那就要看你的<s:textfield>是怎么定义的，如果它没有转换类型，那就会抛这个异常

Answer 12

 <tr> 
      <td height="23" class="td2" align="center">售价： </td> 
      <td class="td1"> <s:textfield name="threads.TPrice" id="TPrice"> </s:textfield> 分 </td> 
    </tr> 

Answer 13

还是验证框架没配对,如果配对了是不会把你输入的值赋给TPrice的,而直接提示验证里面的信息
