hibernate多对多的注解配置中的自动生成中间表的配置:
@Entity
@Table(name="test_student")
public class Students {
@Id
@SequenceGenerator(name="seqStudents",sequenceName="seq_test_student")
@GeneratedValue(generator="seqStudents")
private Integer sid;
private String sname;
/*
* <set name="courseSet" table="test_students_course">
* <key column="stu_id" />
* <many-to-many class="Course" column="cid"/>
* </set>
* */
@ManyToMany
@JoinTable(name="test_students_course",joinColumns={@JoinColumn(name="sid")},inverseJoinColumns={@JoinColumn(name="cid")})
private Set<Course> courseSet;
set,get方法省略
}
@Entity
@Table(name="test_course")
public class Course {
@Id
@SequenceGenerator(name="seqCourse",sequenceName="seq_test_course")
@GeneratedValue(generator="seqCourse")
private Integer cid;
private String cname;
@ManyToMany(mappedBy="courseSet")
private Set<Students> stuSet;
set,get方法省略
}
