I am using play 2.3 and tying to persist an object the console shows the query but data is not inserted in db.
@Entity
@Table(name = "confrence_group")
public class ConfrenceGroup {
@Id
@Column(name = "id", length = 50, unique = true, nullable = false, insertable = false, updatable = false)
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Constraints.Required
@Column(columnDefinition = "varchar(25) default ''")
private String name;
@Column(columnDefinition = "int default 0")
private int active = 1;
@JsonIgnore
@ManyToOne
private User user;
@Formats.DateTime(pattern = "yyyy-MM-dd HH:mm:yy")
@Column(columnDefinition = "TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP")
private Date createdTime;
@Column(unique = true)
private String uid = (new UniqueToken()).nextSessionId();
}
persistence.xml
<?xml version="1.0" encoding="UTF-8"?>

</properties>
</persistence-unit>
</persistence>
to persist I am doing
JPA.em().persist(confGroupObjectReference)
From Logging I can see
insert into confrence_group (active, createdTime, name, uid, user_id) values (1, '[SQL NULL of type 93]', 'akkk', '1474449665379l2urhrti496h0hoplm9cs55srj', 1)
Tried changing it to native query
String sql = "insert into confrence_group ( active
, name
, uid
, user_id
) values (?, ?, ?, ?)";
try {
JPA.em().createNativeQuery(sql)
.setParameter(1, 1)
.setParameter(2, confo.getName())
.setParameter(3, confo.getUid())
.setParameter(4, user_id)
.executeUpdate();
} catch (Exception e) {
e.printStackTrace();
}
Logs
insert into confrence_group (`active`, `name`, `uid`, `user_id`) values (1, 'akkk', '1474443561160ojedp25m5k01e5k1kc7jg39l6p', 1)
But for both cases data not inserted in table as I am checking through my database gui and there is no exception also. The code was working earlier but I dont know what caused it to behave like this
Can anybody help?
EDIT: tried creating new model but the problem is same.
看来您的ID生成是Mysql自动生成的,因此您需要将@GeneratedValue(strategy = GenerationType.AUTO)
更改为@GeneratedValue(strategy=GenerationType.IDENTITY)
