昂首闊步地包裝到超級罐子里后不工作

Question

我有一個在嵌入式Grizzly中運行的Jersey應用程序，其中包含Swagger。 當我從Eclipse運行應用程序時，Swagger可以正常工作。 URL http://localhost:8080/myapp/api-docs返回預期的JSON響應

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

但是，將應用程序打包到單個jar中並運行生成的jar之后，Swagger停止工作。 現在，訪問相同的URL http://localhost:8080/myapp/api-docs將返回HTTP狀態500。該應用程序本身可以正常工作-我可以向Web服務發送請求。

這是我用來打包應用程序的pom.xml 。

您使用的swagger版本非常舊，並且包含對scala的依賴關系等。 建議升級到1.5.3，該列表的依賴項列表較小。

您的jar文件很可能具有不兼容的傑克遜版本，從而導致了問題。

帶拖放向導的Swagger可以毫無問題地構建一個超級jar。
