java - 使用 Swagger 的 Jersey Rest API 文档

Question

我正在尝试使用 Swagger 在 API 文档中查看我的 Jersey 休息服务方法列表。浏览了 GitHub 站点中给出的一些示例/样本。但当我尝试访问上下文根链接时，我仍然无法列出我的服务方法。未找到获取 404 服务。

        String output = "Staring method is invoked";
        return Response.status(200).entity(output).build();
    }
}

My Project structure

正在尝试访问查看列表的链接:http://localhost:8081/SampleRestProject/api-docs

有人可以帮我找出到底哪里出了问题或者我是否遗漏了任何东西。

Answer 1

JerseyJaxrsConfig类是 swagger-jersey2-jaxrs 的一部分库，因此在部署 web 应用程序时不可用，因为您正在使用 swagger-jersey-jaxrs与 Jersey 1.9 结合(很好)。

简单地替换

<servlet-class>io.swagger.jaxrs.config.JerseyJaxrsConfig</servlet-class>

与

<servlet-class>io.swagger.jaxrs.config.DefaultJaxrsConfig</servlet-class>

使用正确的配置类，然后尝试访问 http://localhost:8081/SampleRestProject/rest/swagger.json再次。

此外，在进行此操作时，请考虑将 Swagger 的基本路径定义为相对路径，以便您能够将 Web 应用程序部署在不同的端口上。

<init-param>
    <param-name>swagger.api.basepath</param-name>
    <param-value>/SampleRestProject/rest</param-value>
</init-param>
