Hibernate使用问题记录
复习hibernate的时候老混淆了@joincolumn的用法。mark一下。原文地址http://blog.csdn.net/angryant/article/details/5495810


@ManyToOne中是在本类对应的数据库表中生成

例如

@Entity  @Table(name="score")  public class Score {      private int id;      private Student student;      private Course sourse;      @Id      @GeneratedValue      public int getId() {          return id;      }      public void setId(int id) {          this.id = id;      }      @ManyToOne      @JoinColumn(name="student_id")      public Student getStudent() {          return student;      }      public void setStudent(Student student) {          this.student = student;      }      @ManyToOne      @JoinColumn(name="course_id")      public Course getSourse() {          return sourse;      }      public void setSourse(Course sourse) {          this.sourse = sourse;      }    } 

其中student_id和course_Id都是在score中生成的





而@oneToMany中是在多的一方生成对应一方面的ID
