spring-boot - Spring Boot 未检测到控制器不存在

问题描述

我一直在学习 Spring Boot，但遇到了一个问题。到目前为止，我已经做了一些项目，但我目前正在做的项目是迄今为止最大的一个，所以这里的映射比以前的要多。

我想将这些映射中的一个移动到不同的包中，但在移动后它说了一些类似这样命名的映射，所以我更改了映射的 url，看看它是否可以解决问题。它确实做到了，我可以在新的 url 处访问新的映射，但它引入了另一个问题：自动装配的变量 (lateinit var) 没有被自动装配，而只是抛出了一个未初始化的 lateinit var 的异常。所以我查看了 Spring Boot 的控制台，这是那里的输出：

2018-08-18 14:25:11.169  INFO 20992 --- [  restartedMain] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/app/playlist/{playlistId}],methods=[GET]}" onto private java.lang.String hu.zsemberi.spotifytoyoutube.controller.AppController.showPlaylist(org.springframework.ui.Model,javax.servlet.http.HttpSession,int)

这是我正在使用的控制器（它们在单独的文件中）：

@Controller
@RequestMapping(value = ["/login"])
class LoginController {
    @GetMapping("/spotify")
    fun loginToSpotify() {..}

    @GetMapping("/afterLoginSpotify")
    fun afterLogin() {..}

    @RequestMapping("/loginErrorSpotify")
    fun loginError() {..}
}

@Controller
@RequestMapping(value = ["/app"])
class AppController {
     @GetMapping("/playlists")
     fun showPlaylists() {..}

     @GetMapping("/albums")
     fun showAlbums() {..}

     @GetMapping("/playlist/{playlistId}")
     fun showPlaylist() {..}
}

@RestController(value = "/download")
class DownloadController {
    @PostMapping("/", produces = ["text/plain"])
    fun downloadUris() {..}

    @GetMapping("/progress/{downloadId}")
    fun downloadProgress() {..}

    @GetMapping("/file/{downloadId}", produces = ["application/zip"])
    fun getDownloadZip() {..}
}

如您所见，我没有 spring 认为的那么多控制器。在写出这些原始问题（变量未初始化）后，天知道解决了什么问题，但它仍然写出这些映射。可能是什么问题呢？

解决方案

它自己解决了。我不知道怎么做，因为我什么都没做，几个小时后我又跑了几次项目。
