对于具有FK约束的elementcollection，JpaRepository deleteall（）失败

Question

我正在为我的ORM使用JpaRepository。

@Entity
@DiscriminatorValue(value = "L")
@Table(name = "LARGEPROJECT")
public class LargeProject extends Project {

LargeProject() { // jpa only
}

public String description;

@ElementCollection
public Map<String, String> params = new HashMap<>();

@ElementCollection
public Map<String, String> anotherSet = new HashMap<>();

}

我正在尝试使用以下api进行批量删除： this.largeProjectRepository.deleteAllInBatch();

public interface LargeProjectRepository extends JpaRepository<LargeProject, Long> {
}

我得到了一个例外：

  

org.springframework.dao.DataIntegrityViolationException：无法执行语句; SQL [不适用];约束[＆＃34; FK_K8XLJ5LKC9IK2E39EK06MWUM7：PUBLIC.LARGE_PROJECT_PARAMS FOREIGN KEY（LARGE_PROJECT_PROJECT_ID）REFERENCES PUBLIC.LARGEPROJECT（PROJECT_ID）（1）＆＃34 ;; SQL语句：   从bigproject中删除（project_id）IN（从HT_largeproject中选择project_id）[23503-176]];

我研究了一下，发现了以下内容： How to do bulk delete in JPA when using Element Collections?

How can I cascade delete a collection which is part of a jpa entity?

我想知道JPA是否支持基于API的删除，如@ElementCollection的这些帖子中所述？如果不是最好的方法是什么？
