Mapper method ‘com.LH.mapper.EmployeeMapper.insertEmployee‘ has an unsupported return type: cla 报错

问题：

Mapper method 'com.LH.mapper.EmployeeMapper.insertEmployee' has an unsupported return type: class com.LH.pojo.Employee

映射器方法是com.LH.Mapper.EmployeeMapper。

insertEmployee的返回类型不受支持：class com.LH.pojo.Employee

解决：

因为映射标签使用的是update标签，update标签的返回类型很显然不支持定义的接口类型：

改为

成功解决。
