Spring 数据 Jpa：保存方法仅返回 select 但不执行插入
[英]Spring Data Jpa : Save method only returning select but not performing insert
问题描述
我正在尝试使用 spring 数据 JPA 来保存/更新实体。 我有 2 个几乎相似的实体。 两个实体都包含复合键。 保存方法在一个实体上运行良好。 保存方法不适用于另一个实体。 调用save方法时不会发生插入/更新。 它只是返回 select 语句。
在ContentCoreNluRepository上更新/保存作品
但只有 select 语句从存储库RelationShipTypeRepository返回
我不确定我哪里出错了。
我的代码如下。
@SpringBootApplication
public class CdsRmsOutputDbApplication implements CommandLineRunner {
@Autowired
RelationShipTypeRepository relationShipTypeRepository;
@Autowired
ContentCoreNluRepository contentCoreNluRepository;
public static void main(String[] args) {
SpringApplication.run(CdsRmsOutputDbApplication.class, args);
}
@Override
public void run(String... args) throws Exception {
RelationShipType relationShipType = new RelationShipType("TEJA_3059", "alias", "UUCID", "TEJA_3059", "N");
relationShipTypeRepository.saveAndFlush(relationShipType);
ContentCoreNlu contentCoreNlu = new ContentCoreNlu(4569l, "Topiccsq", "Analyticscqs", "Analytics", "N",
BigDecimal.valueOf(0.9999));
ContentCoreNlu contentCoreNlu1 = new ContentCoreNlu(4569l, "Topiccs", "Analyticscs", "Analytics", "N",
BigDecimal.valueOf(0.9999));
ContentCoreNlu contentCoreNlu2 = new ContentCoreNlu(4569l, "Topic", "Analytics", "Analytics", "N",
BigDecimal.valueOf(0.9999));
List<ContentCoreNlu> contentList = new ArrayList<>();
contentList.add(contentCoreNlu);
contentList.add(contentCoreNlu1);
contentList.add(contentCoreNlu2);
contentCoreNluRepository.saveAndFlush(contentCoreNlu);
}
}
这是我的实体 1

Spring data is performing hibernate merge when entity is assumed as "not new" (see: https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.entity-persistence.saving -entites.strategies ）。 如果实体未更改，则合并不会执行更新。 似乎您已经在 DB 中拥有具有相同标识符的relationShipType实体，并且它等于您尝试更新的实体。
