android - Spring Boot 上的 Controller 415 不支持的媒体类型

Question

您好，我在 Controller 的 Spring Boot 上进行了以下配置:

@RequestMapping(value = "/test/setgamesets", method = RequestMethod.POST,consumes="application/json")
public @ResponseBody Collection<GameSet> setGameSets(@RequestBody ArrayList<GameSet> gmsets) {
            for(GameSet gs : gmsets){
                System.out.println(""+gs.getId());
                gamesets.save(gs);          
            }
            return Lists.newArrayList(gamesets.findAll());
        }

在我的 android 应用程序中:

@POST("/test/setgamesets")
public Collection<GameSet> setGameSets(@Body ArrayList<GameSet> gmsets);

当我在我的 android 应用程序中调用它时，出现此错误:

retrofit.RetrofitError: 415 Unsupported Media Type

你能给我提示在哪里寻找我的错误吗？

感谢您的关注和时间；

您的客户端应用程序应包含 HTTP header Content-Type:application/json 以使其正常工作。但我不是 android 开发人员，所以不知道该怎么做。
