Struts2 Spring3 Hibernate3 菜鸟教程 集成注解版本

集成注解版本和xml版本所不同的地方

• 如果dao，service，action类不是自己写的还是在xml里面进行配置
• 只有是自己写的dao，service，action类，直接在类上面标注对应的注解
• 注解版本不建议继承HibernateDaoSupport实现持久层操作
• 必须要提供事务支持

UserDAOImpl

package com.jege.ssh.dao.impl;import java.util.List;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;import com.jege.ssh.dao.UserDAO;import com.jege.ssh.entity.User;/** * @author JE哥 * @email [e-mail] * @description:dao接口实现 */@Repositorypublic class UserDAOImpl implements UserDAO {  @Autowired  SessionFactory sessionFactory;  private Session currentSession() {    return sessionFactory.getCurrentSession();  }  @Override  public void save(User user) {    currentSession().save(user);  }  @Override  public void update(User user) {    currentSession().update(user);  }  @Override  public void delete(Long id) {    User user = findByKey(id);    if (user != null) {      currentSession().delete(user);    }  }  @Override  public User findByKey(Long id) {    return (User) currentSession().get(User.class, id);  }  @Override  public List<User> findAll() {    return currentSession().createCriteria(User.class).list();  }}

UserServiceImpl

package com.jege.ssh.service.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import com.jege.ssh.dao.UserDAO;import com.jege.ssh.entity.User;import com.jege.ssh.service.UserService;/** * @author JE哥 * @email [e-mail] * @description:业务逻辑层 */@Service@Transactionalpublic class UserServiceImpl implements UserService {  @Autowired  private UserDAO userDAO;  @Override  public void save(User user) {    userDAO.save(user);  }  @Override  public void update(User user) {    userDAO.update(user);  }  @Override  public void delete(Long id) {    userDAO.delete(id);  }  @Override  @Transactional(readOnly = true, propagation = Propagation.SUPPORTS)  public User findByKey(Long id) {    return userDAO.findByKey(id);  }  @Override  @Transactional(readOnly = true, propagation = Propagation.SUPPORTS)  public List<User> findAll() {    return userDAO.findAll();  }}

UserAction

package com.jege.ssh.action;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Controller;import com.jege.ssh.entity.User;import com.jege.ssh.service.UserService;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;/** * @author JE哥 * @email [e-mail] * @description:控制器类 */@Controller@Scope("prototype")public class UserAction extends ActionSupport {  @Autowired  private UserService userService;  private User user;  @Override  public String execute() throws Exception {    ActionContext.getContext().put("users", userService.findAll());    return SUCCESS;  }  @Override  public String input() throws Exception {    if (user != null && user.getId() != null) {      user = userService.findByKey(user.getId());    }    return INPUT;  }  public String save() throws Exception {    if (user == null) {      return execute();    }    if (user.getId() == null) {      userService.save(user);    } else {      userService.update(user);    }    return "redirect";  }  public String delete() throws Exception {    if (user != null && user.getId() != null) {      userService.delete(user.getId());    }    return "redirect";  }  public User getUser() {    return user;  }  public void setUser(User user) {    this.user = user;  }}
