at com.intellij.rt.execution.application.AppMain.main(AppMain.java:147)具体代码如下：
UserMapper
/**
* 添加用户
* */
Integer insertUser(@Param("user") User user);我上网查找错误的时候，解决方法都是说多个参数需要加上@Param注解才能运行成功，但是我刚开始就已经有param注解
后来我以为是xml的问题，仔细检查后发现并不是。
后来去掉@Param之后发现问题解决了，
具体原因尚不清楚，想来和ognl以及mybatis对参数的封装有关系
有时间可以详细了解，不能只停留在会用的层面
