我在现有资源中添加了一个新方法来获取单个产品，之后我的dropwizard应用程序没有盯着并抛出以下错误： - 

Caused by: java.lang.IllegalStateException: Not inside a request scope.

下面是我的get方法的代码，使用它抛出异常： - 

@GET
    @PathParam("{id}")
    @Timed
    public Response get(@PathParam("id") String id){
        Response.ResponseBuilder response = null;
        BaseResponse productResponse = new BaseResponse();
        try {
            Product product = productService.get(id);
            if(product != null)
            {
                productResponse.setOutput(product);
                response.status(200).entity(productResponse);

            }
        }catch (EntityNotPresentException e){
            AppError appError = new AppError();
            appError.setCode(50001);
            appError.setMessage(e.getMessage());
            productResponse.setError(appError);
            response.status(500).entity(productResponse);
        }

        return response.build();
    }

答案 0 :(得分：0)

我刚刚使用存根代码复制并运行我的IntelliJ中的代码，并得到了同样的错误。在花了一些时间进行调试后，我发现get方法不是@Path注释，而是使用@PathParam注释。当我将其更改为正确的@Path注释时。它对我有用。

让我知道它是否能解决您的问题。
