无法使用<url> / api-docs访问swagger文档

标签: java rest jersey-2.0 swagger-2.0

我正在尝试使用Jersey和swagger构建Hello World REST服务来生成文档。 我能够成功调用其余方法,但是当我尝试通过调用来访问swagger文档时:

http://localhost:8080/com.swagger.first/rest/api-docs

我得到'404 Not found'。 (我还尝试将.json添加到最后)

我按照this tutorial中的步骤来构建我的服务。

我的web.xml:

            com.wordnik.swagger.jersey.listing.JerseyResourceListingProvider
        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

<servlet>
    <servlet-name>Jersey2Config</servlet-name>
    <servlet-class>com.wordnik.swagger.jersey.config.JerseyJaxrsConfig</servlet-class>
    <init-param>
        <param-name>api.version</param-name>

    </init-param>
    <init-param>

    </init-param>
    <load-on-startup>2</load-on-startup>
</servlet>

这是我的pom.xml:

    </dependency>
</dependencies>

最后,这是我的服务类:

package com.swagger.first;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
import io.swagger.annotations.*;


@Api( value="hello", description="HelloWrold service")
@Path("/hello")
public class HelloWorld {

@GET
@Produces(MediaType.TEXT_PLAIN)
@ApiOperation(value="Returns 'Hello World!!' string", notes="No comment")
@ApiResponse(code=200, message="Succeeded")
public String helloWorld(){
    return "Hello World!!";
}

@GET
@Produces(MediaType.APPLICATION_XML)
@ApiOperation(value="Returns 'Hello World!!' string as XML", notes="No comment")
@ApiResponses(value = {
        @ApiResponse(code=200, message="Succeeded"),
        @ApiResponse(code=400, message="Testing Swagger")
        })
public String helloWorldXml(){
    return "<hello> Hello World!! </hello>";
}

@GET
@Produces(MediaType.TEXT_PLAIN)
@Path("/echo")
@ApiOperation(value="Returns the query param", notes="No comment")
public String echoStringQueryParam(@ApiParam(name="s", value="any string", required=true) @QueryParam("s") String s){
    return s;
}
}

虽然这个解决方案来得很晚,但我希望它能派上用场找到解决这个问题的人。

您引用的Jersey / Swagger教程未提及Swagger的用户界面未包含在maven安装中。它的核心是生成swagger.json文件,该文件已准备好被Swagger UI使用

如果您要查找此处显示的API文档:http://petstore.swagger.io/

然后,您需要安装以下npm包并将其内容复制到Java项目中的webapp文件夹。 https://www.npmjs.com/package/swagger-ui-dist

您的基本项目结构应如下所示:

enter image description here

您还需要编辑index.html文件,以便在那里定义的url变量链接到本地​​swagger.json文件,而不是默认设置的petstore示例。

就我而言,它看起来像这样:

 <script>
window.onload = function() {

  // Build a system
  const ui = SwaggerUIBundle({
    url: "http://localhost:8080/simple-service-webapp/api/swagger.json",
    dom_id: '#swagger-ui',
    deepLinking: true,
    presets: [
      SwaggerUIBundle.presets.apis,
      SwaggerUIStandalonePreset
    ],
    plugins: [
      SwaggerUIBundle.plugins.DownloadUrl
    ],
    layout: "StandaloneLayout"
  })

  window.ui = ui
}

部署后,您应该能够在浏览器中访问应用程序的根URL时看到文档

感谢Alexender分享此重要信息,这是启动https://hub.packtpub.com/restful-java-web-services-swagger/时可以遵循的另一个链接,当您能够获得本教程链接中提到的swagger.json格式的swagger规范后,我猜应该遵循alexender答复中提到的步骤,以获得最终的精美招摇文档。
