Question

我有一个在嵌入式Grizzly中运行的Jersey应用程序，其中包含Swagger。当我从Eclipse运行应用程序时，Swagger工作正常。 URL http://localhost:8080/myapp/api-docs返回预期的JSON响应

{
"apiVersion": "1.0.0",
"swaggerVersion": "1.2",
"apis": [
    {
        "path": "/myresource",
        "description": "Hello my resource description"
    }
]}

然而，在将应用程序打包到一个罐子中并运行生成的罐子后，Swagger停止工作。访问相同的URL http://localhost:8080/myapp/api-docs现在返回HTTP状态500.应用程序本身工作正常 - 我可以向Web服务发出请求。

这是我用来打包应用程序的pom.xml。

您使用swagger的版本非常陈旧，并且包含对scala的依赖性等。建议升级到1.5.3，它具有较小的依赖列表。

很可能你的jar文件有不兼容的jackson版本导致了这个问题。

Swagger with drop wizard构建了一个没有问题的超级jar。

包装成超级罐后Swagger不工作
