在Spring核心配置文件中没有增加事务方法,导致以上问题
Action类UserAction
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("fly","War of Mercenaries"); userService.add("big-dog","War of Mercenaries"); userService.add("ram","War of Mercenaries"); userService.add("rabbit","War of Mercenaries"); userService.add("hama","War of Mercenaries"); userService.add("shiguan","War of Mercenaries"); userService.update("ram","War of Mercenaries","公羊","佣兵的战争"); userService.delete("rabbit","War of Mercenaries"); userService.getOne(2); userService.findAll(); userService.findYouWant("ram","War of Mercenaries"); return NONE; } }
UserService类
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(String userName,String address) { System.out.println("UserService.................add"); userDao.add(userName,address); } public void update(String userName,String address,String modifyName,String modifyAddress) { System.out.println("UserService.................update"); userDao.update(userName,address,modifyName,modifyAddress); } public void delete(String userName,String address) { System.out.println("UserService.................delete"); userDao.delete(userName,address); } public void getOne(int number) { System.out.println("UserService.................get the number of"); userDao.getOne(number); } public void findAll() { System.out.println("UserService.................find all"); userDao.findAll(); } public void findYouWant(String userName,String address) { System.out.println("UserService.................find you want"); userDao.findYouWant(userName,address); } }
UserDao接口
package com.swift.dao; public interface UserDao { public void add(String userName,String address); public void update(String userName,String address,String modifyName,String modifyAddress); public void delete(String userName,String address); public void getOne(int number); public void findAll(); public void findYouWant(String userName,String address); }
UserDaoImplements类
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(String userName, String address) { // 增加 user.setUsername(userName); user.setAddress(address); hibernateTemplate.save(user); } @Override public void update(String userName, String address, String modifyName, String modifyAddress) { List<User> list = (List<User>) hibernateTemplate.find("from User where userName=? and address=?", userName, address); if (list != null) { for (User user : list) { System.out.println(user.getUsername() + " :: " + user.getAddress()); user.setUsername(modifyName); user.setAddress(modifyAddress); hibernateTemplate.update(user); } } else { System.out.println("您要更新的记录不存在!!!!!"); } } @Override public void delete(String userName, String address) { List<User> list = (List<User>) hibernateTemplate.find("from User where userName=? and address=?", userName, address); if (list != null) { for (User user : list) { System.out.println(user.getUsername() + " :: " + user.getAddress()); hibernateTemplate.delete(user); } } else { System.out.println("您要删除的记录不存在!!!!!"); } } @Override public void getOne(int number) { User user = hibernateTemplate.get(User.class, number); 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(String userName, String address) { List<User> list = (List<User>) hibernateTemplate.find("from User where userName=? and address=?", userName, address); System.out.println(list.toString()); for (User user : list) { System.out.println(user.getUsername() + " :: " + user.getAddress()); } } }
User实体类:
package com.swift.entity; public class User { private Integer uid; private String username; private String address; public Integer getUid() { return uid; } public void setUid(Integer uid) { this.uid = uid; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public User(String username, String address) { this.username = username; this.address = address; } public User(Integer uid, String username, String address) { this.uid = uid; this.username = username; this.address = address; } public User() { super(); // TODO Auto-generated constructor stub } }
web.xml 自动启动监听和过滤器

Spring核心配置文件bean.xml 通过引入各个分模块
