Question

今天，当我启动春季启动项目时，显示如下错误：

我检查了代码，没有发现Controller两个方法定义的路径相同。这是其余控制器的方法定义：

@GetMapping("/vote/first/{gameId}")
Response<List<SparkGameUserVoteFirstResponse>> queryFirstVoteSparkGameUser(@PathVariable(value = "gameId") Long gameId);
@PostMapping("/vote/first")
Response sparkGameUserFirstVote(@RequestBody  @Valid SparkGameUserVoteRequest request);

为什么会发生这种事？我该怎么修？我感觉控制器两次启动。

Answer 1

尝试在文本上运行全局文本搜索"投票/优先"；？(根据错误消息，你可能在这个控制器上有一个api前缀"/spark/game/user"。也许其他地方也会产生联系的api"/spark/game/user/votel/first"(
