Question

我有3个单选按钮 1.Car ， 2.Bike ， 3.Both 。所以，如果我选择汽车它将获取所有的汽车细节，如果我选择2只会获取汽车细节，直到这里我能够实现，但如何如果我选择第3个单选按钮，则同时获取Car和bike详细信息 “都”。在下面的例子中，我想在选择“both”时也这样做它将获取所有文件。对此最好的解决方案是什么？

    Parent class:
    @MappedSuperclass
    public abstract class BaseProsecutionDocument {

    private long dmsDocumentId;
    private long documentVersion;
    private String fileName;
    …
    }

    Pros class:

    @Entity
    @Table(schema = “reference”, name = “prosecution_documents”)
    public class ProsDocument extends BaseProsecutionDocument {

    private Long id;
    private Long prosId;
    private Long ocportalSubmissionId;
    …
    }

    Sumisiion class:

    @Entity
    @Immutable
    @Table(schema = “reference”, name = “submission_docs”)
    public class submissionDocument extends BaseProsecutionDocument {

    private Long id;
    private Long inventionId;
    …
    }
    I want to know how to write the query for that..like
    i have written for those 2 radio buttons:

    public interface ProsecutionDocumentRepository extends JpaRepository {
    @Query(value = “SELECT ppd FROM ProsDocument ppd ” +
    “WHERE ppd.submissionId IN (SELECT p.id FROM submission p WHERE 
UPPER(p.doc) = UPPER(:doc)) ” +
    “AND ppd.documentType.documentType in (‘OFFICE’)”)
    Page findSubmissionOfficeDocumentsByDoc(@Param(“doc”) String docket, 
Pageable pageable);
    }

或者我是否需要将@MappedSuperClass更改为@Entity并使用 @Inheritance（strategy = InheritanceType.JOINED）

Answer 1

首先使用基本字段

创建基类

@MappedSuperclass
public class FooBase {

@Id
private Long id;
private String name;

}

在空类

上将此课程映射到您的表格

@Entity
@Table(name = "foo")
public class Foo  extends FooBase{

}

将嵌套对象，集合，子资源映射到另一个类但是同一个表“foo”

@Entity
@Table(name = "foo")
public class FooNested extends FooBase {

    @Fetch(FetchMode.SUBSELECT)
    @OneToMany(fetch = FetchType.EAGER)
    @JoinColumn(name = "foo_id", insertable = false, updatable = false)
    @ApiModelProperty(hidden = true)
    private List<Bar> barList;
    }

为每个实体创建一份报告
使用一个或另一个存储库来FETCh或不使用已实现的表/实体

@MappedSuperClass上的JPA查询。获取所有子类的详细信息？
