春季數據不保存日期

Question

我有一個簡單的實體和JPA存儲庫的Spring項目。該實體有三個變量：Name (String),active (boolean)和date (java.util.Date)。一旦部署，Hibernate使用varchar,tinyint和datetime在我的MySQL數據庫中創建表。所有似乎都是正確的，但是當我創建/修改實體的實例並調用存儲庫的save()方法時，除日期之外，所有字段都被保存。是否有任何知道的問題與JPA存儲庫或meaby存儲日期我做錯了什麼？

我沒有在這裏放任何代碼，因爲只是一個簡單的類和存儲庫的接口。此外，實體正在保存。我的問題只與日期字段（以及我可以定義的任何其他日期字段）有關。話雖如此，如果有需要的話，就問。

代碼不工作

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

Task類第一線

@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; 

Answer 1

你忘了上添加註解時空結束日期，指定是否應該保留日期，時間或兩者。

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