2,SpringBoot配置文件
3,配置generator

</context>
</generatorConfiguration>
运行generator
运行后生成4个类
4,跳转页面Controller
5,service层
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
@Override
public void addUser(User user) {
this.userMapper.insert(user);
}
@Override
public List<User> showUser() {
UserExample example=new UserExample();
return this.userMapper.selectByExample(example);
}
@Override
public User preUptateUser(int id) {
return this.userMapper.selectByPrimaryKey(id);
}
@Override
@Transactional
public void updateUser(User user) {
this.userMapper.updateByPrimaryKey(user);
}
@Override
public void deleteUser(int id) {
this.userMapper.deleteByPrimaryKey(id);
}
}
6,Controller层
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@PostMapping("/addUser")
public String addUser(User user, Model model)
{
this.userService.addUser(user);
return "redirect:/ok";
};
@GetMapping("/findUser")
public String findUser(Model model)
{
List<User> list = userService.showUser();
model.addAttribute("list",list);
return "showUsers";
};
@GetMapping("/petUpdateUser")
public String petUpdateUser(int id,Model model)
{
User user = this.userService.preUptateUser(id);
model.addAttribute("user",user);
return "updateUser";
};
@PostMapping("/updateUser")
public String updateUser(User user)
{
this.userService.updateUser(user);
return "redirect:/ok";
};
@GetMapping("/deleteUser")
public String deleteUser(int id)
{
this.userService.deleteUser(id);
return "redirect:/ok";
};
}
7,启动类加入
