Spring Data 与 QueryDslPredicateExecutor 没有找到类型错误的属性 findAll

Question

我尝试按照Spring Data JPA with QueryDSL中的教程进行操作

我的代码版本如下: spring-boot = 1.3.8.release 查询 dsl = 3.7.4

我的实体如下

@Entity
@Table(name = BatchAPIEntity.TABLE)
public class BatchAPIEntity extends BatchEntity {

    @JsonView(View.API.class)
    @Column(name = KEY_NIT)
    String nit;
}

我的存储库如下

public interface BatchApiRepository extends JpaRepository<BatchAPIEntity,Long>, QueryDslPredicateExecutor<BatchAPIEntity>{}

当我编译和构建代码时，显示以下错误

我的错误类似于以下问题中给出的错误，但问题是它没有答案

Error in findAll

我也尝试了这个答案，但没有任何好的结果

经过一番阅读后，我解决这个问题的方法是使用 QueryDslJpaRepository 而不是两个单独的接口(interface)，如下所示:

public interface BatchApiRepository extends QueryDslJpaRepository<BatchAPIEntity, Long>
