无法将SQL查询映射到实体spring-data-jpa

[英]Trouble mapping SQL Query to Entity spring-data-jpa

 原文  2017-11-10 10:31:24  8   2    java/ spring/ jpa/ spring-data

问题描述

我是Spring的新手，正在尝试锻炼如何将SQL查询映射到模型对象。 我正在开发的原型在数据仓库的顶部提供了一个REST API。 将数据库表映射到对象很容易，但是某些对象将由更复杂的查询表示。 到目前为止，我已经尝试了@NamedNativeQuery和@SqlResultsMapping和@Entity批注，但是遇到了一些问题。 我怀疑我没有正确使用它们？

我可以启动并运行服务器，但是尝试通过localhost：8080 / admissionEvents访问时出现错误。 我正在使用sqlite数据库，但在使用生产mssql数据库时也遇到了同样的问题。 据我所知，有一个正在寻找表的SQLException？ 那表明我的映射有问题吗？ 注释是否在正确的位置？

我没有定义persistence.xml文件，但是我的数据库连接详细信息在application.properties中设置。 不知道是不是问题的根源？

任何帮助，不胜感激。

请尝试以下方式。 

@Entity
@Table(name = "admission_event")
public class AdmissionEvent {...}

通过将@Subselect和@Synchonize批注添加到Entity Class来设法找到解决方案。 

@Entity(name="AdmissionEvent")
@Subselect("SELECT fact_admission_event.fact_admission_event_key,fact_admission_event.ward FROM fact_admission_event")
@Synchronize({"fact_admission_event"})
public class AdmissionEvent {
@Id
@Column(name="fact_admission_event_key")
private int id;

@Column(name="ward")
private String wardLocation;

protected AdmissionEvent() {
}
{}
