如何将Swagger与Maven + Java + Jersey + Tomcat集成

如果您已将文件从 https://github.com/wordnik/swagger-ui 正确复制到项目中（目录必须复制到您的 目录），则可以访问 上的 API 文档。不要忘记修改，以便Swagger知道在哪里加载API文档：distsrc/main/webapphttp://.../MyService/index.htmlindex.html

window.swaggerUi = new SwaggerUi({
    url: "http://localhost:8080/MyService/rest/api-docs",

必须将“如果”中的 API 基路径设置为 if 是您在类的实现中使用注释定义的应用程序路径。web.xmlhttp://.../MyService/restrestjavax.ws.rs.core.Application@ApplicationPath

以下是我通常执行的操作的示例（我不用于配置）：web.xml

@ApplicationPath( "api" )
public class MyRestApplication extends Application
{
   @Override
   public Set<Class<?>> getClasses( )
   {
       Set<Class<?>> resources = new HashSet<Class<?>>( );
       resources.add( ApiListingResource.class );
       resources.add( ApiDeclarationProvider.class );
       resources.add( ApiListingResourceJSON.class );
       resources.add( ResourceListingProvider.class );
       resources.add( Ping.class ); // my own resource class
       swaggerConfiguration( );
       return resources;
   }

   private void swaggerConfiguration( )
   {
      SwaggerConfig swaggerConfig = new SwaggerConfig( );
      ConfigFactory.setConfig( swaggerConfig );
      swaggerConfig.setApiVersion( "0.0.1" ); 
      swaggerConfig.setBasePath( "http://localhost:8080/MyService/api" );
      ScannerFactory.setScanner( new DefaultJaxrsScanner( ) );
      ClassReaders.setReader( new DefaultJaxrsApiReader( ) );
   }
}

这是使用弹簧，雄猫，球衣，maven，swagger的最简单的例子。以下是项目结构。

HelloWorldService 的代码。

package com.rest;
import com.wordnik.swagger.annotations.Api;
import com.wordnik.swagger.annotations.ApiOperation;
import com.wordnik.swagger.annotations.ApiResponse;
import com.wordnik.swagger.annotations.ApiResponses;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

/**
 * Created by neerbans on 11/3/2016.
 */

@Path("/hello")
@Api( value = "/hello", description = "print hello world")
public class HelloWorldService {

    @ApiOperation(
            value = "method api",
            notes = "method api notes"
    )
    @ApiResponses(value = {
            @ApiResponse(code = 200, message = "success"),
            @ApiResponse(code = 500, message = "error")
    })
    @Produces({MediaType.TEXT_PLAIN})
    @GET
    @Path("/{param}")
    public String getMsg(
            @PathParam("param")
            String msg
    ) {

        String output = "Jersey say : " + msg;

        return output;
    }

}

SwaggerApp.class

package com.rest;

import com.wordnik.swagger.config.ConfigFactory;
import com.wordnik.swagger.config.ScannerFactory;
import com.wordnik.swagger.config.SwaggerConfig;
import com.wordnik.swagger.jaxrs.config.ReflectiveJaxrsScanner;
import com.wordnik.swagger.jaxrs.listing.ApiDeclarationProvider;
import com.wordnik.swagger.jaxrs.listing.ApiListingResource;
import com.wordnik.swagger.jaxrs.listing.ApiListingResourceJSON;
import com.wordnik.swagger.jaxrs.listing.ResourceListingProvider;
import com.wordnik.swagger.jaxrs.reader.DefaultJaxrsApiReader;
import com.wordnik.swagger.reader.ClassReaders;
import org.glassfish.jersey.message.MessageProperties;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.ServerProperties;

import javax.annotation.PostConstruct;

/**
 * Created by neerbans on 11/3/2016.
 */
public class SwaggerApp extends ResourceConfig {

    public SwaggerApp() {
        register(HelloWorldService.class);

        register(ApiListingResource.class);
        register(ApiDeclarationProvider.class);
        register(ApiListingResourceJSON.class);
        register(ResourceListingProvider.class);

        property(MessageProperties.XML_FORMAT_OUTPUT, true);
        property(ServerProperties.TRACING, "ALL");
    }

    @PostConstruct
    public void initializeSwaggerConfiguration() {

        final ReflectiveJaxrsScanner scanner = new ReflectiveJaxrsScanner();
        scanner.setResourcePackage("com.rest");
        ScannerFactory.setScanner(scanner);
        ClassReaders.setReader(new DefaultJaxrsApiReader());
        final SwaggerConfig config = ConfigFactory.config();
        config.setApiVersion("1.0");
        config.setBasePath("http://localhost:8080/jax-rs/rest");
    }
}

设置项目后。构建它并将 war 文件部署到 Tomcat webapps 文件夹中。
运行Tomcat并点击下面的URL：

http://localhost:8080/jax-rs/rest/api-docs

For swagger-ui

http://localhost:8080/jax-rs
