表格列是
f_receive datetime NOT NULL`，
和java是
@Id
@Column(name = "f_receive")
private Date receive = new Date ();
我使用
Criteria criteria = getQuerySession ().createCriteria (entityClass);
criteria.list ();
但是当执行criteria.list（）;它扔了

@Temporal(TemporalType.TIMESTAMP)
@Column(name = "f_receive")
private Date receive;
//setter and getter
@Temporal表示日期字段。答案 1 :(得分：0)
首先：将Date作为主键是不可取的，因此从f_receive列中删除@Id并使用适当的Temporal类型注释来定义Date，如 -
@Temporal(TemporalType.DATE)
@Column(name = "f_receive")
private Date receive;
有多种方法可以在JPA中使用Date的时间类型，如：
TemporalType.DATE
TemporalType.TIME
TemporalType.TIMESTAMP
第二：无需初始化日期字段，因为您可以从setter方法设置日期字段的值，因此请将其设置为字段。
@Column(name = "f_receive")
private Date receive;
并为该字段提供getter和setter。
