private List<AutoOddsList>  autoOddsList;

Answer 1

问题解决了。那我就当一回事后诸葛亮吧。NoSuchMethodException: setMinCash是不是AutoOdds类少了setMinCash方法。

Answer 2

MinCash 变量的get和set方法没有

Answer 3

估计是没有将 表单的enctype="multipart/form-data" method="post"

Answer 4

一切照常，只需要将form中的name这个属性去掉即可

Answer 5

<form> 里没写 method 提交方式吧?

Answer 6

我今天也遇到了这个问题 估计是AutoOdds字段类型错了吧，你提交的是String类型，你定义这个实体的这个字段是不是String类型呢？

Answer 7

在使用struts2时 要把在action中定义的int 类型 转换为  Integer对象类型就行了
