mysql – @GeneratedValue不起作用. “java.sql.SQLException：字段’ID’没有默认值”

MySQL 前端之家
前端之家收集整理的这篇文章主要介绍了mysql – @GeneratedValue不起作用. “java.sql.SQLException：字段’ID’没有默认值”，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

上下文：Jboss5.1,MySql 5.0

我已经尝试了很多可能性..一个简单的@GeneratedValue或其他解决方案明确指定序列生成器,但也有同样的问题…
有堆栈跟踪

有趣部分的实际实体代码：

@Entity
public class Lavoro implements Serializable {
    private static final long serialVersionUID = 1L;


    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    private String nome;

    private String sede;

    private String stato;

我遇到错误的代码：

Lavoro lavoro = new Lavoro();
        lavoro.setNome(formLavoro.getNome());
        lavoro.setSede(formLavoro.getSede());
        lavoro.setStato("PENDENTE");
        lavoro.setPersona(p);
        lavoro.setAbilitas(listaAbilita);
        lavoro.setRichiestapartecipazionelavoros(new ArrayListFeedbacks(new ArrayList<Feedback>());
        System.out.println("Prima del persist");
        manager.persist(lavoro);

注意：经理是实体经理.

用于ID字段的MysqL设置为NOT_NULL和AUTO_INCREMENT.

最佳答案
也许你应该检查映射.将其他表中使用的ID作为外键可能会出现问题？
