使用springdatajpa管理多对多关系时,需要字段筛选并封装,分页,模糊查询时,应该如何做?

@Entity

@Table(name = "app")

@AllArgsConstructor

@NoArgsConstructor

@JsonIgnoreProperties(value = { "hibernateLazyInitializer", "handler"})

@Data

public class AppDetail implements Serializable {

    }



    @ManyToMany(fetch = FetchType.EAGER,targetEntity = Classify.class)
