mybatis 插入空值时报错 TypeException

报错内容：nested exception is org.apache.ibatis.type.TypeException: Could not set parameters for mapping: ParameterMapping{property='transferPersitionTime', mode=IN, javaType=class java.lang.Object, jdbcType=null, numericScale=null, resultMapId='null', jdbcTypeName='null', expression='null'}. Cause: org.apache.ibatis.type.TypeException: Error setting null for parameter #9 with JdbcType OTHER . Try setting a different JdbcType for this parameter or a different jdbcTypeForNull configuration property. Cause: java.sql.SQLException: 无效的列类型

之前使用的是mysql，后面转为 oracle ，切换之后插入数据就报错

插入空值时需要制定类型

所以我们指定类型就好了

insert into
	clean_user(id,status,update_time,mip,emp_name,emp_code,old_unit_code,old_unit_name,new_unit_code,new_unit_name,transfer_persition_time,erp_uid,backup1,backup2,backup3)
	values(
	SYS_GUID(),
	#{status,jdbcType=VARCHAR},
	#{updateTime,jdbcType=TIMESTAMP},
	#{mip,jdbcType=VARCHAR},
	#{empName,jdbcType=VARCHAR},
	#{empCode,jdbcType=VARCHAR},
	#{oldUnitCode,jdbcType=VARCHAR},
	#{oldUnitName,jdbcType=VARCHAR},
	#{newUnitCode,jdbcType=VARCHAR},
	#{newUnitName,jdbcType=VARCHAR},
	#{transferPersitionTime,jdbcType=VARCHAR},
	#{erpUid,jdbcType=VARCHAR},
	#{backup1,jdbcType=VARCHAR},
	#{backup2,jdbcType=VARCHAR},
	#{backup3,jdbcType=VARCHAR}
	)

　　有什么类型呢，查看 org.apache.ibatis.type.JdbcType.java 就可以看到了。
