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

Question

Today when I start the spring boot project, shows error like this:

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

I check the code, and did not found the Controller two method define with the same path. this is the rest controller method define:

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

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

why did this happen? what should I do to fix it?I feel like the controller initial twice.

Answer 1

Try running a global text searching on text "/vote/first"? (Based on error msg you may have an api prefix "/spark/game/user" on this controller. Maybe somewhere else also produce the contacted api "/spark/game/user/vote/first")
