刚开始用到MyEclipse导入项目，启动没问题，框架Spring+mybatis，后来导入到eclipse就报这个错，说bean没有创建成功，然后网上各种百度，都没解决，大概有以下几种思路：

1.servers或者dao（这里mybatis用动态代理，在server引入的时候注入下即可）注解未注解，或者server引入dao层的时候未注解

2.在方法上加@RequestParam

3.配置文件未扫描,还有其他的可以搜一下

....

我这里这几种都试了一下，没有解决，最后点击报错的地方，发现跳转不到引入的jar包，仔细看了下，Referenced Libraries和lib下都有，可就是跳转不到，然后复制了myeclipse的，然后build path 然后add，竟然不报这个错了，又报了另一个错，这个没深究...然后发现找不到的这个包在lib下的一个文件夹内，再然后把所有的lib下的文件夹下的所有包移了出来，然后add，启动成功！

原因：eclipse读取不到lib文件夹下的文件夹内的jar

不知道这个算不算eclipse的bug，在Myeclipse下就没问题，以下是我的lib目录结构！
