原因：java.lang.IllegalStateException：不明确的映射。 不能 map 'com.sportswin.soa.spark.controller.ISparkGameUserController' 方法

Question

今天当我启动 spring 启动项目时，显示如下错误：

2022-01-21 14:52:04.659 ERROR 1 --- [           main] o.s.boot.SpringApplication               : Application run failed

我检查了代码，并没有发现 Controller 两种方法定义的路径相同。 这是 rest controller 方法定义：

    @GetMapping("/vote/first/{gameId}")
    Response<List<SparkGameUserVoteFirstResponse>> queryFirstVoteSparkGameUser(@PathVariable(value = "gameId") Long gameId);

    @PostMapping("/vote/first")
    Response sparkGameUserFirstVote(@RequestBody  @Valid SparkGameUserVoteRequest request);

为什么会这样？ 我应该怎么做才能解决它？我觉得 controller 初始两次。

Answer 1

尝试对文本“/vote/first”运行全局文本搜索？ （根据错误消息，您可能在此 controller 上有一个 api 前缀“/spark/game/user”。也许其他地方也会产生联系的 api“/spark/game/first”）
