默认情况下，Swagger只初始化扫描仪和配置一次。如果你有多个应用程序或服务器，你需要通过BeanConfig为每个应用程序设置一个scannerId，scannerId和contextId，这应该与你的servlet配置中的值相匹配。我想这个设置只适用于最新版本的swagger。我用swagger-1.5.13试过。下面是一个例子。

public class PublicApplication extends Application {

public PublicApplication() {

    BeanConfig beanConfig = new BeanConfig();
    beanConfig.setVersion("1.0");
    beanConfig.setTitle("A Fine Title");
    beanConfig.setDescription("A Fine Description.");
    beanConfig.setSchemes(new String[]{"http"});
    beanConfig.setBasePath("/api"); 
    beanConfig.setResourcePackage("com.test.rest.resource.external");
    beanConfig.setPrettyPrint(true);

    // Set configId,contextId & scannerId
    beanConfig.setConfigId("public");  
    beanConfig.setContextId("public");
    beanConfig.setScannerId("public");
    beanConfig.setScan(true);

}

字符串
您的AdminApplication类

public AdminApplication() {

    BeanConfig beanConfig = new BeanConfig();
    beanConfig.setVersion("1.0");
    beanConfig.setTitle("Another Fine Title");
    beanConfig.setDescription("Another Fine Description.");
    beanConfig.setSchemes(new String[]{"http"});
    beanConfig.setBasePath("/apiTwo"); 
    beanConfig.setResourcePackage("com.test.rest.resource.internal");
    beanConfig.setPrettyPrint(true);

    // Set configId,contextId & scannerId
    beanConfig.setConfigId("admin");  
    beanConfig.setContextId("admin");
    beanConfig.setScannerId("admin");
    beanConfig.setScan(true);
    beanConfig.setScan(true);
}

您还应该在servlet配置中指定URL ID、contextId和scannerId作为init参数，如下所示。

<servlet>
    <servlet-name>jersey-rest-public</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.test.rest.resource.PublicApplication</param-value>
    </init-param>
    <init-param>
        <param-name>swagger.scanner.id</param-name>
        <param-value>public</param-value>
    </init-param>
    <init-param>
        <param-name>swagger.context.id</param-name>
        <param-value>public</param-value>
    </init-param>
    <init-param>
        <param-name>swagger.config.id</param-name>
        <param-value>public</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet>
    <servlet-name>jersey-rest-admin</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.test.rest.resource.AdminApplication</param-value>
    </init-param>
    <init-param>
        <param-name>swagger.context.id</param-name>
        <param-value>admin</param-value>
    </init-param>
    <init-param>
        <param-name>swagger.scanner.id</param-name>
        <param-value>admin</param-value>
    </init-param>
    <init-param>
        <param-name>swagger.config.id</param-name>
        <param-value>admin</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

我遇到了同样的问题，但与 Swagger v3。它花了我安静的一些努力来解决它，所以我想分享它。

    private val openApi by lazy { initOpenApi() }

    @GET

    open fun getSchema() = openApi

    private fun initOpenApi(): OpenAPI {
        val initial = OpenAPI().apply {
            info(Info().title("Application title"))
            servers(
                listOf(
                    Server().url(servletConfig.servletContext.contextPath)
                )
            )
        }
        val applications = applications.toList()

        val openApi = applications.fold(initial) { initial, app ->
            val context = JaxrsOpenApiContext<JaxrsOpenApiContext<*>>()
            context.app(app)
            context.setOpenApiReader(Reader(initial).apply { setApplication(app) })
            context.setOpenApiScanner(JaxrsApplicationScanner().application(app))
            context.read()
        }

        return openApi
    }

如果您已经在Application类中注册了所有的jaxrs资源，那么这是可行的。

• 不要忘记注册io.swagger.v3.jaxrs2.SwaggerSerializers。*
