Question

我对Struts 2非常熟悉......自从3天以来我一直陷入一个非常奇怪的问题我的动作类中有很多属性;一些是整数，其他是字符串。我知道我已经为我的所有属性创建了两个getter / setter
showcase扩展了struts-default和json-default，因为我需要类来渲染一个json表，我正在使用 struts2-jquery gridtag ....没有我的属性被打印exept sord，sdix，page ..由标签定义的那些

显示页面的值，但myeditOptions的值不是..... Pleeeease帮助

Answer 1

@ Lord-zed我看到你只在prepare（）方法上填充myEditOptions。当“执行”动作被击中时，它不再被填充。因此，您必须在execute（）中再次填充它，或者在prepare操作的jsp中放入一个隐藏字段，以将其发布回“执行”操作。我建议在execute（）中重新填充它。

Answer 2

没有必要对getter和setter进行类型转换，您应该创建不同的getter和setter以及DAO文件。

Struts2没有显示字符串属性
