插入数据库时​​事务中止

Question

当我运行我的应用程序时，它给了我这个错误：Transaction aborted

我的 bean 代码是：

@Named(value = "index")
@SessionScoped
public class index implements Serializable {

   @EJB FreindsFacadeLocal freinds;
    public index() {
}
public List<Freinds> getMessage(){
    Freinds fr = new Freinds();
    fr.setId(Integer.MAX_VALUE);
    fr.setFirstname("Abc");
    fr.setLastname("mnb");
    fr.setNickname("Ali Nrd");
    fr.setFreindsince(null);
    fr.setEmail("ali.nrd@gmail.com");
    freinds.create(fr);   
    return "hello all"();
}
}

而服务器日志是：

Answer 1

错误信息提到：

Internal Exception: java.sql.SQLSyntaxErrorException: Table/View 'FREINDS' does not exist.

检查您的表格的拼写方式。提示：通常是FRIENDS。

Answer 2

感谢 ydaetskcoR

最后...我从实体中删除了表名注释，它工作正常

@Entity
@Table(name = "FREINDS")
@XmlRootElement
@NamedQueries({
@NamedQuery(name = "Freinds.findAll", query = "SELECT f FROM Freinds f"),....

我删除这个：

@Table(name = "FREINDS")

应用程序运行成功
