主要问题:

Error instantiating class XXX with invalid types () or values ().

大神解释

这个异常表示通过反射创建你自定的JavaBean失败，因为你没有默认的构造方法，或者是你使用了< constructor>标签，但是没有符合该标签结构的构造函数。

解决方案:

方法一:ResultMap中不使用< constructor>标签

上面这种方式对Bean进行映射，必须存在一个默认的构造函数，否则就会抛出这个错误。

方法二:

ResultMap中使用< constructor>标签

那么type所对应的实体类中要有与< constructor>标签内对应column对应的有参构造
