大家注意一下 struts.xml和web.xml都配齐了

Answer 1

'LoginUserAction' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Instantiation of bean failed; nested exception is

路径配置不对，可能没有classes 然后看看你有没有applicationContext.xml 文件

追问

是这样的，没有配置Action注入，别的都是好用的。你向什么dao ,biz,这几个注入都好用。可是现在注入ACTION就报错了

Answer 2

注入到LoginUserAction中的类xml中配置了吗

追问

struts.xml和web.xml都配齐了

追答

我是说在LoginUserAction中有没有调用service，调用的那个service有没有配置

追问

dao.service 全都配置了（注入）

Answer 3

类目录下有[com.web.action.LoginUserAction]这个类吗？错误提示，初始化这个bean类出问题。

追问

有

Answer 4

LoginUserAction没有在xml注入吧，这个都不配？
