JAX-WS ::从独立的Java 7 SE客户端调用Web服务的方法 [英] JAX-WS :: ways to call a web service from a standalone Java 7 SE client

问题描述

我正在尝试独立的JAX-WS Web服务，服务器和客户端（意思是，不在Java EE容器内运行）。一个好的SO帖子显示独立的服务器端是这一个。

I am experimenting with standalone JAX-WS web services, server and client side (meaning, not running inside a Java EE container). A good SO post showing standalone server-side is this one.

对于客户端我发现以下三种方式似乎有效（使用 wsimport 生成客户端存根）：

For the client side I've found the following three ways that seem to work (following use of wsimport to generate the client stubs):

public static void main(String[] args) throws Exception {
    String serviceURL = "http://localhost:9000/soap?wsdl";
    {   // WAY 1
        URL url = new URL(serviceURL);
        QName qname = new QName("urn:playground:jax-ws", "MyService");
        Service service = Service.create(url, qname);
        IHello port = service.getPort(IHello.class);
        System.out.println(port.sayHello("Long John"));
    }
    {   // WAY 2
        MyService service = new MyService();
        IHello port = service.getHelloPort();

        ((javax.xml.ws.BindingProvider) port).getRequestContext().put(javax.xml.ws.BindingProvider.ENDPOINT_ADDRESS_PROPERTY, serviceURL);

        System.out.println(port.sayHello("Long John"));
    }
    {   // WAY 3
        URL url = new URL(serviceURL);
        QName qname = new QName("urn:playground:jax-ws", "MyService");
        MyService service = new MyService(url, qname);
        IHello port = service.getHelloPort();
        System.out.println(port.sayHello("Long John"));
    }
}

我不知道任何其他客户模式 - 边访问或上面显示的方式如何相互比较。

I am not aware of any other patterns of client-side access or how the ways shown above compare against each other.

应该注意的任何其他方法或权衡？

Any other methods or trade-offs one should be aware of?

推荐答案

最后，经过一些实验，我认为下面显示的方式（摘自这里）与我之前的三个问题相比具有明显的优势：

In the end, after some experimentation, I think the way shown below (taken from here) has distinct advantages compared to the previous three in my question:

{   // WAY 4
    QName qname = new QName("urn:playground:jax-ws", "MyService");
    MyService service = new MyService(null, qname);
    IHello port = service.getHelloPort();
    BindingProvider bindingProvider = (BindingProvider) port;
    bindingProvider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, serviceURL);
    System.out.println(port.sayHello("John Silver"));
}

优点是：

• WSDL在运行时不检索（为什么它应该是？它已经在代码创建时用于创建客户端存根）


• 服务的网址是 在存根中硬编码。

• the WSDL is not retrieved at runtime (and why should it be? it's already been used at code creation time to create the client stub)
• the URL of the service is not hardcoded in the stub.
