Java 尝试访问{API}/swagger.json-jersey 1.x swagger core 1.5.8时出现错误404

我正在尝试将swagger（版本1.5.8）集成到使用jersey 1.19的现有RESTAPI中。 我遵循了在jersey 1.x应用程序中实现swagger的方法，但无论我尝试什么，端点（localhost:8080/swagger.json）总是返回404

应用程序在docker容器中运行，该容器记录资源是在运行时发现的

这些资源可以在my.namespace.webservice中找到。 在任何地方都没有定义@ApplicationPath，因此如果我理解正确，我应该能够通过调用localhost:8080/swagger.json获得swagger.json

任何指向正确方向的指针都会非常有用
