UserAction类代码：

package com.swift.action;import com.opensymphony.xwork2.ActionSupport;
import com.swift.service.UserService;public class UserAction extends ActionSupport {
private UserService userService;
public void setUserService(UserService userService) {
this.userService = userService;
}
@Override
public String execute() throws Exception {
System.out.println("action..................");
userService.add();
userService.update();
userService.delete();
userService.getOne();
userService.findAll();
userService.findYouWant();
return NONE;
}}

调用UserService类中crud各种方法

UserService类代码：

package com.swift.service;import org.springframework.transaction.annotation.Transactional;import com.swift.dao.UserDao;
@Transactional
public class UserService { private UserDao userDao;
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
public void add() {
System.out.println("UserService.................add");
userDao.add();
}
public void update() {
System.out.println("UserService.................update");
userDao.update();
}
public void delete() {
System.out.println("UserService.................delete");
userDao.delete();
}
public void getOne() {
System.out.println("UserService.................get the 3rd");
userDao.getOne();
}
public void findAll() {
System.out.println("UserService.................find all");
userDao.findAll();
}
public void findYouWant() {
System.out.println("UserService.................find you want");
userDao.findYouWant();
}}

调用UserDao接口

package com.swift.dao;public interface UserDao {
public void add();
public void update();
public void delete();
public void getOne();
public void findAll();
public void findYouWant();
}

接口实现类UserDaoImplements

package com.swift.dao;import java.util.List;import org.springframework.orm.hibernate5.HibernateTemplate;import com.swift.entity.User;public class UserDaoImplements implements UserDao{
private HibernateTemplate hibernateTemplate;
private User user;
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public void setUser(User user) {
this.user = user;
} @Override
public void add() {
//增加
user.setUsername("small-fly");
user.setAddress("War of Mercenaries");
hibernateTemplate.save(user);
} @Override
public void update() {
//修改
user.setUsername("big-dog");
user.setAddress("The War of Mercenaries");
hibernateTemplate.update(user);
}
@Override
public void delete() {
hibernateTemplate.delete(user);
}
@Override
public void getOne() {
User user=hibernateTemplate.get(User.class, 2);
System.out.println(user.getUsername()+" :: "+user.getAddress());
}
@Override
public void findAll() {
List<User> list=(List<User>) hibernateTemplate.find("from User");
for(User user:list) {
System.out.println(user.getUsername()+" :: "+user.getAddress());
}
}
@Override
public void findYouWant() {
List<User> list=(List<User>) hibernateTemplate.find("from User where userName=? and address=?","ram","The War of Mercenaries");
for(User user:list) {
System.out.println(user.getUsername()+" :: "+user.getAddress());
}
}}
