Answer 1

是这样的，我是用struts做上传附件，其中在form中跟页面的input type="file"做了绑定，form中FormFile绑定页面的上传框

Answer 2

现在点上传就出错，不会跳转到action中来

Answer 3

进不了action？
检查下你的struts的配置有没有问题。

Answer 4

配置没有错，找到跳转不过的原因了，但为什么一个form绑定多个元素，有的有值有的没值呢

Answer 5

Method.java:585 你的这个类中的585行出错了，类型不匹配，是不是从数据库出来的数据和这个类型不匹配啊

Answer 6

IllegalArgumentException此异常表明向方法传递了一个不合法或不正确的参数。

Answer 7

可能是在页面上的<input type="file" name=""/>的name属性的名字和po的名字不一样，所有不会跳到action中去！我上次就是名字不一样结果一直不跳action

Answer 8

我也是这个错误！！我是用Struts和Hibernate做了一个两个表联接 ！数据填完。，当点击保存的时候就出现了错误！纠结啊！
