Metro 与 jax-ws 覆盖端点地址

发布于 2024-12-10 17:07:13 字数 825 浏览 0 评论 0原文

我正在使用 Metro 和 jax-ws 创建一个 Web 服务客户端，并且我想覆盖端点地址。

使用 2.11.1 中的以下示例。 BindingProvider.ENDPOINT_ADDRESS_PROPERTY 我可以这样做：但是

//Create service and proxy from the generated Service class.
HelloService service = new HelloService();
HelloPort proxy = service.getHelloPort();

((BindingProvider)proxy).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
                                                    "http://new/endpointaddress");

proxy.sayHello("Hello World!");

我不知道不明白为什么我不能使用service.getHelloPort().sayHello("Hello World!") 而不是 proxy.sayHello("Hello World!") 如示例所示。如果这样做，Web 服务客户端将使用其默认端点地址，而不是我想要使用的地址。

看起来每次我调用 getHelloPort() 时都会得到一个 HelloPort 的新实例

有人能解释一下吗？

I'm creating a webservice client using Metro with jax-ws and I want to override the endpoint address.

Using the following example from 2.11.1. BindingProvider.ENDPOINT_ADDRESS_PROPERTY I can do that:
http://metro.java.net/guide/How_to_invoke_and_endpoint_by_overriding_endpoint_address_in_the_WSDL.html

//Create service and proxy from the generated Service class.
HelloService service = new HelloService();
HelloPort proxy = service.getHelloPort();

((BindingProvider)proxy).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
                                                    "http://new/endpointaddress");

proxy.sayHello("Hello World!");

But I don't understand why I can't use the service.getHelloPort().sayHello("Hello World!") instead of proxy.sayHello("Hello World!") as the example shows. If I do, the webservice client is using its default endpoint address instead of the one I want to use.

It looks like I'm getting a new instance of HelloPort every time I call getHelloPort()

Can anyone explain this?

它们之间几乎没有（读：没有）区别：

service.getHelloPort().sayHello("Hello World");

并且

HelloPort proxy = service.getHelloPort();
proxy.sayHello("Hello World!");

service.getHelloPort() 调用将始终返回一个新的代理/端口实例。因此，每当您修改给定端口对象的请求上下文时，该修改都是特定端口实例的本地修改。

一般来说，只要您不修改请求/响应上下文，您返回的端口实例就可以重用并且线程安全。对于您发布的代码示例，它正在修改请求上下文以设置端点地址，因此建议每次需要时获取一个新的端口对象，或者至少为每个需要的线程获取一个新对象一。（threadlocal 是你的朋友）

there is little (read: no) difference between these:

service.getHelloPort().sayHello("Hello World");

and

HelloPort proxy = service.getHelloPort();
proxy.sayHello("Hello World!");

the service.getHelloPort() call will always return a new proxy/port instance. so any time you modify the request context for a given port object that modification is local to the specific port instance.

generally speaking the port instance you get back is re-usable and thread safe as long as you dont modify the request/response contexts. for the code sample you posted, it is modifying the request context to set the endpoint address, so it is advisable to get a new port object either every time you need one, or at the very least get a new object for each thread that needs one. (threadlocal is your friend for this)
