Operator SIMPLE_PROPERTY on rid requires a scalar argument, found interface java.util.List in method

jpa上的一个小坑

1. 错误信息：

Caused by: java.lang.IllegalStateException: Operator SIMPLE_PROPERTY on rid requires a scalar argument, found interface java.util.List in method public abstract java.util.List com.example.demo.Dao.AdminRolePermissionDao.findAllByRid(java.util.List).
	at org.springframework.data.jpa.repository.query.PartTreeJpaQuery.throwExceptionOnArgumentMismatch(PartTreeJpaQuery.java:171) ~[spring-data-jpa-2.4.2.jar:2.4.2]
	at org.springframework.data.jpa.repository.query.PartTreeJpaQuery.validate(PartTreeJpaQuery.java:147) ~[spring-data-jpa-2.4.2.jar:2.4.2]
	at org.springframework.data.jpa.repository.query.PartTreeJpaQuery.<init>(PartTreeJpaQuery.java:90) ~[spring-data-jpa-2.4.2.jar:2.4.2]
	... 43 common frames omitted

2. 根据错误信息分析错误来源：AdminRolePermissionDao.findAllByRid（）错误。

List<AdminRolePermission> findAllByRid(List<Integer> rids);

3. 根据查询资料进行调试（即在方法名后加In）：

List<AdminRolePermission> findAllByRidIn(List<Integer> rids);

4. 问题得到了解决
