PO类及映射文件编写：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

            </key>
            <one-to-many class="gdou.laiminghai.po.Student" />
        </set>
    </class>
</hibernate-mapping>

Student.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

            <column name="iClaId" />
        </many-to-one>

Dao编写：

参考自：http://blog.csdn.net/wuxintdrh/article/details/77841664
BaseDao.java

public interface BaseDao<T> {
    long save(T t);
    void delete(int id);
    T get(int id);
    void update(T t);
    List<T> getByHql(String hql);
}

BaseDaoImpl.java

public class BaseDaoImpl<T> extends HibernateDaoSupport implements BaseDao<T>{
    @Resource(name="sessionFactory")
    public void setSuperSessionFactory(SessionFactory sessionFactory) {
        super.setSessionFactory(sessionFactory);
    }

    @Override
    public long save(T t) {
        return (int) getHibernateTemplate().save(t);
    }

    @Override
    public void delete(int id) {
        getHibernateTemplate().delete(get(id));
    }

    @Override
    public T get(int id) {
        return getHibernateTemplate().get(getClz(), id);
    }

    @Override
    public void update(T t) {
        getHibernateTemplate().update(t);
    }

    @Override
    public List<T> getByHql(String hql) {
        return (List)getHibernateTemplate().find(hql);
    }

    //获取泛型的类
    private Class<T> clz;
    @SuppressWarnings("unchecked")
    public Class<T> getClz() {
        if (clz == null) {
            clz = (Class<T>)(((ParameterizedType)(this.getClass().getGenericSuperclass())).getActualTypeArguments()[0]);
        }
        return clz;
    }
}

Service编写：

略

Action编写：

StudentAction.java

//模型驱动 
public class StudentAction extends ActionSupport implements ModelDriven<Student> {

    private Student student = new Student();

    @Autowired
    private StudentService studentService;

    @Override
    public Student getModel() {
        return student;
    }

    @Override
    public String execute() throws Exception {
        studentService.save(student);
        ActionContext.getContext().put("students", studentService.getAllStudents());
        return SUCCESS;
    }
}

ClazzAction.java

//属性驱动 
public class ClazzAction extends ActionSupport {

    private Clazz clazz;
    private Set<Student> students;

    @Autowired
    private ClazzService clazzService;

    public Clazz getClazz() {
        return clazz;
    }

    public void setClazz(Clazz clazz) {
        this.clazz = clazz;
    }

    public Set<Student> getStudents() {
        return students;
    }

    public void setStudents(Set<Student> students) {
        this.students = students;
    }

    @Override
    public String execute() throws Exception {
        clazz.setStudents(students);
        clazzService.save(clazz);
        ActionContext.getContext().put("clazzs", clazzService.getAllClazzs());
        return SUCCESS;
    }
}

ClazzAction 需要封装Set集合，注意在action当前目录下添如下配置文件：
ClazzAction-conversion.properties

KeyProperty_students=stuId

页面：

添加Clazz：
