Cause: java.lang.IllegalStateException: Type handler was null on parameter mapping for property ‘__frch_item_0’ jdbcType (null) combination.
原因竟然是:
有个变量名字叫batchId(傻X取的名字),引起了deleteBatchIds映射报错?
改名了就好了。
参考:
mybatis 引用对象属性映射错误 or could not be found for the javaType (xxx.model) : jdbcType (null) combination.
