测试方法package zq.ssh.test;import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import zq.ssh.domain.User;
import zq.ssh.service.UserService;public class TestApp {

public static void test(){
User user = new User();
user.setUsername("ss");
user.setPassword("123456");
String xmlPath="applicationContext.xml";
ApplicationContext applicationContext = new ClassPathXmlApplicationContext(xmlPath);
UserService userService = (UserService)applicationContext.getBean("userService",UserService.class);
userService.saveUser(user);
System.out.println(user);
}
public static void main(String[] args) {
test();
}
}
运行结果数据库结果

项目结构求各位大佬帮忙解决一下，谢谢！

Answer 1

Id是自增长的嘛？user和userservice代码是什么？

Answer 2

id是自增的UserService.javapackage zq.ssh.service;import java.util.List;import zq.ssh.domain.User;public interface UserService {
public void saveUser(User user);
public void updateUser(User user);
public void deleteUser(User user);
public User findUserById(Integer id);
public List<User> findAllUser();
}
UserServiceImpl.java
package zq.ssh.service.impl;import java.util.List;import zq.ssh.dao.UserDao;
import zq.ssh.domain.User;
import zq.ssh.service.UserService;public class UserServiceImpl implements UserService{
private UserDao userDao; public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
public UserDao getUserDao() {
return userDao;
}
public void saveUser(User user) {
// TODO Auto-generated method stub
this.userDao.save(user);
} public void updateUser(User user) {
// TODO Auto-generated method stub
this.userDao.update(user);
} public void deleteUser(User user) {
// TODO Auto-generated method stub
this.userDao.delete(user);
} public User findUserById(Integer id) {
// TODO Auto-generated method stub
return this.userDao.findById(id);
} public List<User> findAllUser() {
// TODO Auto-generated method stub
return this.userDao.findAll();
}

}

Answer 3

hibernate.cfg.xml里面设置<property name="connection.autocommit">true</property>

Answer 4

这个是事务没有提交，有没有写原始的jdbc程序啊，connection.setAutoCommit(false);然后connection.commit();上面那个属性如果不设置就相当于connection.commit()这句话没有执行
