使用JPA命名查询的仅日期比较，没有时间

问题描述

我的数据库的列为DATE.

生成实体时，它在实体类中创建了一个Timestamp字段.

When generated the entity, it created a Timestamp field in the entity class.

@Column(name="MY_DATE")
private Timestamp myDate;

我的传入对象是java.util.Date对象. startDate和endDate.

My incoming object is a java.util.Date object. startDate and endDate.

我需要编写一个JPA查询，该查询将获取在startDate和endDate之间具有my_date的记录.这是需要考虑的时间.

I need to write a JPA query that will fetch the records that has my_date between startDate and endDate. It is taking time into consideration.

查询条件

o.myDate >=:inputDate AND o.myDate <=:inputDate

推荐答案

您的实体代码是否自动生成?也许您应该尝试更新生成的实体代码.将myDate字段的类型更改为Date而不是java.sql.Timestamp.然后用@Temporal注释它，并指定DATE作为类型，如下面的代码所示:

Is your entity code auto-generated? Maybe you should try updating your generated Entity code. Change the type of myDate field to Date instead of java.sql.Timestamp. Then annotate it with @Temporal and specify DATE as the type, as shown in the code below:

@Column(name="MY_DATE")
@Temporal(TemporalType.DATE)
private Date myDate;

在查询中，您可以使用BETWEEN代替比较运算符:

In your query, you can use BETWEEN instead of comparison operators:

o.myDate BETWEEN :startDate AND :endDate
