Java Spring启动应用程序无法热交换更改

我正在做一个Spring Boot项目，我试图将我们的IDE从STS切换到Intellice。除调试时外，一切正常。每当我更改Java类时，Spring都会尝试重新启动整个应用程序，但失败时会显示以下消息：

Spring启动运行配置中有一个选项，可以在重新启动应用程序上下文之前尝试热交换：

正确的触发器文件选项将自动添加到命令行。

您的

UserService

是否用

@Service

注释？你能用类签名扩展你的问题，包括它们的注释吗？你能启动你的应用程序吗？或者您在热插拔功能方面有问题？@HakanDilek是的，正如关于环境的第7条所指出的。此外，应用程序启动正常，并处理请求。当我在调试已在执行的应用程序时尝试更改某些内容时，就会出现此问题。可能是您遗漏了任何注释，可能是

@Controller

或

@RestController

上的

@UserController

或

@Service

上的

@Service

更新了帖子描述。控制器似乎设置正确。 com.xyz |-service | |-IUserService | |-impl | |-UserService |-controller |-UserController @Autowired private IUserService userService

@org.springframework.web.bind.annotation.RestController
@RequestMapping(value = "/user", produces = MediaType.APPLICATION_JSON_VALUE)
public class UserController{

    @Autowired
    private IUserService userService;
    ...
}
