我不知道问题所在。运行这个时，它不会在MySQL数据库中插入值...我对这个主题很陌生...请帮助我的朋友......无论如何感谢提前的朋友...... !!!

解决方案

这是错误的： String forward =SUCCESS;



正确的字符串是成功; 

 字符串转发=成功;

并且，由于您正在扩展ActionSupport，因此您可以使用常量SUCCESS来防止将来的语法错误。 / p> 

  String forward = SUCCESS;

Struts.xml中必须存在相同的映射。如果你在Struts.xml中输入SUCCESS，那就去改变它，以防止未来的麻烦......



PS：与ERROR相同应该是error 。


Actually I'm working on implementing Struts Spring & Hibernate Integration on online Exam project. But While I'm submitting the values in the JSP page, it throws me the following error:

I don't know where the problem is. While running this, it doesn't inserting the values in the mysql DB... I'm very new to this topic...Please Help me Friends... Anyway thanks in Advance friends...!!!

解决方案

This is wrong: String forward = "SUCCESS";

The right String is "success"; 

String forward = "success";

and, since you are extending ActionSupport, you can use the constant SUCCESS to prevent future syntax errors.

String forward = SUCCESS;

The same mapping has to exist in Struts.xml. If you put "SUCCESS" in Struts.xml, go and change it, to prevent future headaches...

P.S: Same for "ERROR" that should be "error".

这篇关于Struts未处理的异常 - 未定义行为的结果 - Struts Spring&amp;休眠集成的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
