如何解决答案的结果时间很长，如何在使用jpa时减少它？

@Entity
    @Table(name = "demo")
    public class DemoEntity {

    @ElementCollection
    @Column(name = "demo_type_id",nullable = false)
    @CollectionTable(name = "demo_entity_record_type",joinColumns = @JoinColumn(name = 
"demo_entity_id"))
    private Set<recordtype> recordtypes = new HashSet<>();

    @ElementCollection
    @Column(name = "demo_type_id",nullable = false)
    @CollectionTable(name = "demo_entity_record_type1",joinColumns = @JoinColumn(name = 
"demo_entity_id"))
    private Set<DemoType> demoTypes1 = new HashSet<>();

    @ElementCollection
    @Column(name = "demo_type_id",nullable = false)
    @CollectionTable(name = "demo_entity_record_type2",joinColumns = @JoinColumn(name = 
"demo_entity_id"))
    private Set<RecorType> recordtypes2 = new HashSet<>();
    }

我在数据库中有 3000 条实体记录。当我尝试获取 3000 个实体时，我在日志中看到：

3000 select to entity table
3000 select to test_entity_record_type table by test_entity_id
3000 select to test_entity_record_type1 table by test_entity_id
3000 select to test_entity_record_type2 table by test_entity_id

结果回答时间很长。如何减少？

解决方法

你可以使用@BatchSize注解：

@BatchSize(size = 1000)
private Set<RecordType> recordTypes = new HashSet<>();

让我知道这是否有效。
