异常详细信息如下，报错的位置是User类的uId属性的setter方法，可是本人很确定setter方法没问题。更加诡异的是假如本人把uId的getter和setter方法全删掉，再写一遍，然后重新部署，竟然没问题了。然后等本人再用一会，重启了几次后，这个异常 又会蹦出来。高手们有什么想法，快被这个问题整吐了。
另本人一个同时说是Driver和User对应的两张表的主键名称相同(都是u_id)造成的，driver表外键引用user表

public void setUId(int uId) {
this.uId = uId;
}
public int getUId() {
return uId;
}
setUId和getUId的U都要大写。

本人用mybatis从来不用resultMap的 都用的原生态的sql，
sql里面as resulttype里面的属性就可以了 用resultMap太容易出错。

你 set/get 方法不是工具生成的吗。
把get/set 全删除掉，重新生成一遍。
this.uId = uId;
}
public int getuId() {
return uId;
