@Service
public class UserService {
    
    @Cached(name = "userCache", key = "#id", expire = 3600)
    public User getUserById(int id) {
        // 从数据库中查询用户信息
        User user = userRepository.findById(id);
        return user;
    }
    
    @CacheInvalidate(name = "userCache", key = "#id")
    public void deleteUserById(int id) {
        // 删除用户信息
        userRepository.deleteById(id);
    }
    
    @CacheUpdate(name = "userCache", key = "#user.id", value = "#user")
    public void updateUser(User user) {
        // 更新用户信息
        userRepository.update(user);
    }
    
}

@RestController
public class UserController {
    
    @Autowired
    private UserService userService;
    
    @GetMapping("/user/{id}")
    public User getUser(@PathVariable int id) {
        return userService.getUserById(id);
    }
    
    @DeleteMapping("/user/{id}")
    public void deleteUser(@PathVariable int id) {
        userService.deleteUserById(id);
    }
    
    @PutMapping("/user")
    public void updateUser(@RequestBody User user) {
        userService.updateUser(user);
