Spring Security:在后台任务中使用@PreAuthorize调用方法的正确方法是什么？

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    // 配置其他安全相关内容
}

@Service
public class UserService {
    @PreAuthorize("hasAuthority('user:delete')")
    public void deleteUser(Long id) {
        // 删除用户逻辑
    }
}

@RestController
@RequestMapping("/users")
public class UserController {
    @Autowired
    private UserService userService;

    @DeleteMapping("/{id}")
    public ResponseEntity<?> deleteUser(@PathVariable Long id) {
        userService.deleteUser(id);
        return ResponseEntity.ok("用户删除成功");
    }
}
