MyBatis 两表关联查询，一对多关系，两表字段相同，子表个别列的数据被覆盖，通过修改主表映射xml解决问题
问题描述：MyBatis 两表关联查询，一对多关系，两表字段相同，子表个别列的数据被覆盖。
解决前
控制台打印结果：
[ classid = 611, code = userStatus, name = 用户状态, memo = 用户状态,oid = null, status = 1,parclassid = 610, path = 1.352.610.611.,isnode = 1 ][ dictid = 612, classid = 611, code = userStatus, name = 用户状态, zjm = ZC, memo = 用户状态,oid = null,status = 1]
[ dictid = 613, classid = 611, code = userStatus, name = 用户状态, zjm = GQ, memo = 用户状态,oid = null,status = 1]
[ dictid = 614, classid = 611, code = userStatus, name = 用户状态, zjm = ZX, memo = 用户状态,oid = null,status = 1]
[ dictid = 615, classid = 611, code = userStatus, name = 用户状态, zjm = SD, memo = 用户状态,oid = null,status = 1]
[ dictid = 681, classid = 611, code = userStatus, name = 用户状态, zjm = WJF, memo = 用户状态,oid = null,status = 1]
解决后控制台打印结果：
[ classid = 611, code = userStatus,name = 用户状态, memo = 用户状态,oid = null, status = 1,parclassid = 610, path = 1.352.610.611.,isnode = 1 ]
[ dictid = 612, classid = 611,code = 1, name = 正常, zjm = ZC, memo = 正常,oid = 1,status = 1]
[ dictid = 613, classid = 611,code = 2, name = 挂起, zjm = GQ, memo = 挂起,oid = 2,status = 1]
[ dictid = 614, classid = 611,code = 3, name = 注销, zjm = ZX, memo = 注销,oid = 3,status = 1]
[ dictid = 615, classid = 611,code = 4, name = 锁定, zjm = SD, memo = 锁定,oid = 4,status = 1]
[ dictid = 681, classid = 611,code = 5, name = 未缴费, zjm = WJF, memo = null,oid = 5,status = 1]
条件描述：
BASE_DICTIONARY_KIND表里的主键是BASE_DICTIONARY_INFO表的外键。一对多关系。
