mybatis插入数据时报错:
Cause: org.apache.ibatis.executor.ExecutorException: Error getting generated key or setting result to parameter object. Cause: java.sql.SQLException: 不支持的特性
at org.apache.ibatis.exceptions.ExceptionFactory.wrapException(ExceptionFactory.java:8)
原因:加了如下标红的设置(useGeneratedKeys="true"把新增加的主键赋值到自己定义的keyProperty(id)中)
<insert id="insert" parameterType="com.vimtech.bms.business.domain.monitor.finan.AssetsVisitReportWithBLOBs" useGeneratedKeys="true" keyProperty="serialid">
解决方法一:没什么用的话,删除标红的即可;
解决方法二:用selectKey先查下自增的主键ID值然后赋给相应的主键ID即可
oracle的写法(查序列的下一个值然后赋值):
<selectKey resultType="java.lang.Long" order="BEFORE" keyProperty="###">
SELECT SEQ_ASSETS_VISIT_REPORT.nextval AS ### FROM dual
</selectKey>
SQLServer的写法
<selectKey resultType="java.lang.Integer" keyProperty="timelineConfigId">
SELECT @@IDENTITY AS TIMELINE_CONFIG_ID
</selectKey>
