Java JPA Spring存储库日期筛选返回空数组

在两个日期之间调用查询将返回一个空数组，但它不应该返回

我正在使用这个“简单”的spring存储库：

import java.time.LocalDate;
import java.util.List;
import org.springframework.data.repository.CrudRepository;
import com.company.app.domain.DailySales;

public interface DailySalesRepo extends CrudRepository<DailySales, Long> {

    public List<DailySales> findByDateBetween(LocalDate start, LocalDate end);
}

将该跟踪复制到SQL控制台将返回101项：

select dailysales0_.id as id1_0_, dailysales0_.amount as amount2_0_, dailysales0_.currency as currency3_0_, dailysales0_.date as date4_0_, dailysales0_.tenantId as tenantId5_0_ from agg_dailysells dailysales0_ where dailysales0_.date between "2016-02-01" and "2016-05-12";

结果：返回101行

但是

List result

得到一个空列表

我做错了什么

我的实体看起来像：

@Entity
@Table(name="agg_dailysells")
public class DailySales implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;
    private Integer tenantId;
    private LocalDate date;
    private Double amount;
    private Integer currency;

    ... getters and setters go here ...

据我所知，Hibernate4不支持Java8时间API。您应该使用

java.util.Date

而不是任何java8时间抽象，或者升级到Hibernate5，并将

Hibernate-java8

模块添加到依赖项中。有关Java

LocalDate

和Hibernate 4的更多信息，您可以看到这一点。

Hibernate 4不支持Java 8 LocalDate或LocalDateTime API。原因是Hibernate4和JPA2.1是在Java8之前发布的\

幸运的是，JPA2.1支持将实体属性转换为数据库列表示，反之亦然。您可以使用此界面在日期和本地日期之间进行转换

您必须重写两个方法，一个用于实体属性到数据库列，另一个用于数据库列到属性

@Converter(autoApply = true)
public class LocalDateAttributeConverter implements AttributeConverter<LocalDate, Date> {

    @Override
    public Date convertToDatabaseColumn(LocalDate locDate) {
        return (locDate == null ? null : Date.valueOf(locDate));
    }

    @Override
    public LocalDate convertToEntityAttribute(Date sqlDate) {
        return (sqlDate == null ? null : sqlDate.toLocalDate());
    }
}

看看这个博客。

哪个版本的hibernate和Spring数据？我使用的是org.hibernate:hibernate entitymanager:4.2.0.Final和org.springframework.Data:Spring数据jpa:1.9.4。RELEASE@BlackBishop如果仍然相关，请看我的答案。

@Entity
@Table(name="agg_dailysells")
public class DailySales implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;
    private Integer tenantId;
    private LocalDate date;
    private Double amount;
    private Integer currency;

    ... getters and setters go here ...

@Converter(autoApply = true)
public class LocalDateAttributeConverter implements AttributeConverter<LocalDate, Date> {

    @Override
    public Date convertToDatabaseColumn(LocalDate locDate) {
        return (locDate == null ? null : Date.valueOf(locDate));
    }

    @Override
    public LocalDate convertToEntityAttribute(Date sqlDate) {
        return (sqlDate == null ? null : sqlDate.toLocalDate());
    }
}

@Entity
@Table(name="agg_dailysells")
public class DailySales implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;
    private Integer tenantId;

    @Column
    @Convert(converter = LocalDateAttributeConverter.class)
    private LocalDate date;

    private Double amount;
    private Integer currency;
