加个断点调试看看，是不是哪边参数没传或者传的不对

Mapped Statements collection does not contain value for后面是什么类什么方法之类的： 
错误原因有几种： 
1、mapper.xml中没有加入namespace 
2、mapper.xml中的方法和接口mapper的方法不对应 
3、mapper.xml没有加入到mybatis-config.xml中(即总的配置文件)，例外：配置了mapper文件的包路径的除外 
4、mapper.xml文件名和所写的mapper名称不相同。

以下是spring的配置文件spring.xml

代码是这样的,调试过去就报上述那个错误,蛋疼的要命…………

引用 5 楼 aiafei0001 的回复:

com.mbk.yb.model.user.UserDao.getUserById？？ .user.UserDao?

还是报错,找不出原因来,跪求帮助!!!!

看一下user.xml里的命名空间对不对

我把所有的代码都贴在楼上了,请帮我看看

<mapper namespace=”com.mbk.yb.dao.UserDao”>

哪里错了?
实在不解

配置文件检查一下，是不是符合代码的要求

配置文件也贴在上面了,没找出原因来
