hibernate annotations疑问
在学习hibernate annotation的时候遇到一个疑问：SQL SERVER数据库有自增主键的时候，使用annotations的时候设置@Id后，插入提示：当 IDENTITY_INSERT 设置为 OFF 时，不能为表 'Teacher' 中的标识列插入显式值。
代码如下：
public static void main(String[] args) { Teacher t = new Teacher(); t.setName("annotations"); t.setTitle("annotations test"); Configuration cfg = new AnnotationConfiguration(); SessionFactory sf = cfg.configure().buildSessionFactory(); Session session = sf.openSession(); session.beginTransaction(); session.save(t); session.getTransaction().commit(); session.close(); sf.close(); }@Entitypublic class Teacher { private int id; private String name; private String title; @Id public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; }
