本来想把公司项目整理一下,把xml 配置换成注解方式自己重新搭了一个框架 struts2.2.1 + hibernate3.5.5 + spring2.5.6 ,搭框架也是十分不顺利,
靠google 和 baidu 解决 n 多 bug 后, 这个bug 让我束手无策,从上午10 点到 现在一直在找!无赖只好求助!不知道没有人遇到过.帮帮我.thanks!
在网上找到报我类似错也有(比如:http://zhongzhihua.iteye.com/blog/613305) 但是解决方法行不通,主要是autowired 自动装配问题.
关于自动装配问题也可以看看人家说的典型错误: http://www.blogjava.net/chaocai/archive/2007/12/04/165134.html

struts2 自动装配认是安照类型装配的,一般报这错原因是 一个接口有二个实现 而另一个类引用这个接口所以struts2 不知道装配那一个,这时这句话里中括号 No unique bean of type [com.scirp.dao.board.IBoardDAO] 会出现两个实现这个接口的类,这时很好判断!
而我这个也报这个错但只有一个选择.所以很纳闷!经过反复测试才发现有一个dao接口dao实现类型不一样,然后找代码发 我上面写的代码 CategoryDAOImpl extends CitCoreServiceImpl<Category> ,二个实现的继承都写错了,我晕!
写代码的确要小心.struts2 这样框架错误又不好，除非以前遇到过,可以快速定位错误! 哥一个杯具!
