Spring启动应用程序无法热交换更改

Question

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：

Description:

Field userService in com.xyz.controller.UserController required a bean of type 'com.xyz.service.IUserService' that could not be found.


Action:

Consider defining a bean of type 'com.xyz.service.IUserService' in your configuration.

以下是有关环境的一些上下文：

>

spring boot devtools 1.5.9依赖项被添加到pom.xml中

“首选项”选项-

我尝试过使用“cmd shift a”选项进行调试-

IDE版本是

IDE版本

spring boot starter父版本是1.5.9.0版本

以下结构描述了类层次结构：

com.xyz
|-service
|  |-IUserService
|  |-impl
|     |-UserService
|-controller
   |-UserController

@Autowired
private IUserService userService

另外，我已经尝试了这个线程中的所有答案，但没有成功地解决问题。有人面对过这个问题吗？预期的行为不是重新启动整个应用程序，而只是热交换更改的工件。

编辑：

以下是UserController示例：

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

    @Autowired
    private IUserService userService;
    ...
}

Answer 1

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。
