Question

我正在尝试在核心java项目（swing应用程序）中部署restful web-service。我正在使用jersy。我已经搜索到谷歌的许多网站，但我无法找到为什么这附加。

public class Main { 
public static void main(String[] args) throws Exception{        
    ResourceConfig resourceConfig = new ResourceConfig(MyResource.class);
    URI baseUri = UriBuilder.fromUri("http://localhost/").port(10049).build();

    HttpServer server = JdkHttpServerFactory.createHttpServer(baseUri,resourceConfig);
    server.start();
    System.out.println("Press Enter to stop the server. ");
    System.in.read();
    server.stop(0);
}
}


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

// This method is called if TEXT_PLAIN is request
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
    return "Hello Jersey";
}

// This method is called if XML is request
@GET
@Produces(MediaType.TEXT_XML)
public String sayXMLHello() {
    return "sdasd";
}

// This method is called if HTML is request
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHtmlHello() {
    return "dsdfd";
}
}

例外：

 Exception in thread "main" java.lang.IllegalStateException: server in wrong state
at sun.net.httpserver.ServerImpl.start(ServerImpl.java:139)
at sun.net.httpserver.HttpServerImpl.start(HttpServerImpl.java:58)
at org.glassfish.jersey.jdkhttp.JdkHttpServerFactory$2.start(JdkHttpServerFactory.java:363)

的Maven：

<dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-jdk-http</artifactId>
        <version>2.22.1</version>
    </dependency>

如何解决上述异常。

Answer 1

通过删除 server.start（）;

行来解决此问题

行 JdkHttpServerFactory.createHttpServer（baseUri，resourceConfig）; 正在创建http服务器以及启动服务器。

＆＃34;服务器处于错误状态异常＆＃34;当你试图再次启动服务器时出现。
