带有QueryDslPredicateExecutor的Spring数据未找到类型错误的属性findAll

Question

我尝试使用QueryDSL学习Spring Data JPA教程

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

@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，下面的错误是show

我的错误与下面问题中给出的类似，但问题是它不是答案

经过一些阅读，我可以解决这个问题的方法是使用QueryDslJpaRepository，而不是两个单独的接口，如下所示：

public interface BatchApiRepository extends QueryDslJpaRepository<BatchAPIEntity, Long>
