我有一个简单的实体和JPA存储库的Spring项目。该实体有三个变量:Name (String),active (boolean)date (java.util.Date)。一旦部署,Hibernate使用varchar,tinyintdatetime在我的MySQL数据库中创建表。所有似乎都是正确的,但是当我创建/修改实体的实例并调用存储库的save()方法时,除日期之外,所有字段都被保存。是否有任何知道的问题与JPA存储库或meaby存储日期我做错了什么?春季数据不保存日期

我没有在这里放任何代码,因为只是一个简单的类和存储库的接口。此外,实体正在保存。我的问题只与日期字段(以及我可以定义的任何其他日期字段)有关。话虽如此,如果有需要的话,就问。

代码不工作

Task task = taskService.findDispatchableTask(); 
task.setDispatched(true); // This is saved 
task.setEndDate(new Date()); // But this not 
taskService.save(task); 

Task类第一线

@Entity 
@Table(name = "sttv_tasks") 
public class Task { 
    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    @Column(name = "tsk_id") 
    private Long id; 

    @Column(name = "tsk_end_date") 
    private Date endDate;

请发布具有实体映射,存储库定义以及客户端代码的域类。 – 2013-05-04 12:42:24

感谢您的回答@OliverGierke。我刚更新了这篇文章。 – 2013-05-04 13:10:19

你忘了上添加注解时空结束日期,指定是否应该保留日期,时间或两者。

@Column(name = "tsk_end_date") 
@Temporal(TemporalType.TIMESTAMP) 
private Date endDate; 
+0

我不知道我必须这样做。非常感谢你! – 2013-05-04 14:06:31
