错误原因：
Departmentt department = new Departmentt();
    department.setDepartmentid(new Integer(3));这里非得从1开始插入然后只能插入2；
    department.setDepartmentname("computer");
    department.setTeachertSet(new HashSet());

    Teachert teacher = new Teachert();
    teacher.setTeacherid(new Integer(1));
    teacher.setDepartmentt(department);

    Teachert teacher1 = new Teachert();
    teacher1.setTeacherid(new Integer(4));
    teacher1.setDepartmentt(department);

    //session.save(teacher);
    department.getTeachertSet().add(teacher);
    department.getTeachertSet().add(teacher1);

    session.save(department);
初学各位请多多指教;
