org.apache.ibatis.builder.BuilderException: Error resolving JdbcType.从字面上面来理解这个异常，很明显是错误解析JdbcType，即在resultMap映射的时候，<result>或<id>元素的jdbcType属性填写不正确。请读者仔细检查你的Mapper配置文件中jdbcType是否书写有误。
java.lang.IllegalArgumentException: No enum const class org.apache.ibatis.type.JdbcType.INTGER
该提示更是明确表示MyBatis中没有INTGER的JdbcType，将INTGER改为INTEGER。即可！
