Spring Boot 415 上的控制器不受支持的媒体类型

Question

您好，我的 Controller 上的 Spring Boot 有以下配置：

@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());
        }

在我的安卓应用中：

@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，我收到了这个错误：

retrofit.RetrofitError: 415 Unsupported Media Type

你能告诉我在哪里寻找我的错吗？

感谢您的关注和时间；

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