java - 带有 Spring 示例失败的嵌入式 Jetty

Question

我正在研究将 Jetty 嵌入 REST 服务的示例:

http://aredko.blogspot.com/2013/01/going-rest-embedding-jetty-with-spring.html

AppConfig 看起来像这样:

package com.example.config;

import java.util.Arrays;
import javax.ws.rs.ext.RuntimeDelegate;
import com.example.rs.HelloWorldService;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.endpoint.Server;
import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;
import org.codehaus.jackson.jaxrs.JacksonJsonProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.example.rs.JaxRsApiApplication;

@Configuration
public class AppConfig {

    @Bean( destroyMethod = "shutdown" )
    public SpringBus cxf() {
        return new SpringBus();
    }

    @Bean
    public Server jaxRsServer() {
        JAXRSServerFactoryBean factory = RuntimeDelegate.getInstance().createEndpoint( jaxRsApiApplication(), JAXRSServerFactoryBean.class );
        factory.setServiceBeans( Arrays.< Object >asList( helloWorldService() ) );
        factory.setAddress( "/" + factory.getAddress() );
        factory.setProviders( Arrays.< Object >asList( jsonProvider() ) );
        return factory.create();
    }

    @Bean
    public JaxRsApiApplication jaxRsApiApplication() {
        return new JaxRsApiApplication();
    }

    @Bean
    public HelloWorldService helloWorldService() {
        return new HelloWorldService();
    }

    @Bean
    public JacksonJsonProvider jsonProvider() {
        return new JacksonJsonProvider();
    }
}

我的 hello world 网络服务非常简单:

package com.example.rs;

import java.util.Collection;

import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path( "/hello" )
public class HelloWorldService {

    @Inject private JaxRsApiApplication jaxRsApiApplication;

    @Produces( { "text/plain" } )
    @GET
    public String helloWorld( ) {
        return "Hello, World";
    }
}

还有我的 web Starter 类:

package com.example;

import org.apache.cxf.transport.servlet.CXFServlet;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;

import com.example.config.AppConfig;

public class Starter {
    public static void main( final String[] args ) throws Exception {
        Server server = new Server( 8080 );

        // Register and map the dispatcher servlet
        final ServletHolder servletHolder = new ServletHolder( new CXFServlet() );
        final ServletContextHandler context = new ServletContextHandler();
        context.setContextPath( "/" );
        context.addServlet( servletHolder, "/rest/*" );
        context.addEventListener( new ContextLoaderListener() );

        context.setInitParameter( "contextClass", AnnotationConfigWebApplicationContext.class.getName() );
        context.setInitParameter( "contextConfigLocation", AppConfig.class.getName() );

        server.setHandler( context );
        server.start();
        server.join();
    }
}

但是当我编译它并运行生成的带有依赖项的 jar 时，我得到了多个堆栈跟踪，从这里开始:

我的目标是制作一个带有嵌入式 Jetty 的无 XML 独立 jar。我做错了什么，我该如何解决？

我正在经历同样的问题...但是我认为是特定机器中的问题...我在另外两台机器上检查了同一个项目并工作...我尝试了另一个服务器应用程序和问题仍然...当我调试我的 bean 时，我通过我意识到 RuntimeDelegate 是那台机器中的异常...
