How to make a SOAP call in Java
提问by Jenni
This seems like it should be simple, but maybe I'm missing something. I just want to make a SOAP call in Java, preferrably using only built-in APIs. I'm a little overwhelmed looking at javax.xml.soappackage in the Java documentation. I have tried searching Google, but it seems like all the results are from 2000-2002, and they are all talking about libraries that can be used for SOAP calls (before SOAP libraries were built in, I guess).
这看起来应该很简单，但也许我遗漏了一些东西。我只想用 Java 进行 SOAP 调用，最好只使用内置 API。看着Java 文档中的javax.xml.soap包，我有点不知所措。我试过在 Google 上搜索，但似乎所有结果都是 2000-2002 年的，而且它们都在谈论可用于 SOAP 调用的库（我猜是在内置 SOAP 库之前）。
I don't need to handle the SOAP request; only make one. This sitehas an example that is pretty simple, but it doesn't use the built-in Java SOAP libraries. How would I do basically the same thing using core Java?
我不需要处理 SOAP 请求；只做一个。该站点有一个非常简单的示例，但它不使用内置的 Java SOAP 库。我将如何使用核心 Java 做基本相同的事情？
// Create the parameters
Vector params = new Vector( );
params.addElement(
new Parameter("flightNumber", Integer.class, flightNumber, null));
params.addElement(
new Parameter("numSeats", Integer.class, numSeats, null));
params.addElement(
new Parameter("creditCardType", String.class, creditCardType, null));
params.addElement(
new Parameter("creditCardNumber", Long.class, creditCardNum, null));
// Create the Call object
Call call = new Call( );
call.setTargetObjectURI("urn:xmltoday-airline-tickets");
call.setMethodName("buyTickets");
call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
call.setParams(params);
// Invoke
Response res = call.invoke(new URL("http://rpc.middleearth.com"), "");
// Deal with the response

Soap has changed a lot since the early days. You can do things like what you describe, but it is not common.
自早期以来，肥皂发生了很大变化。你可以做你描述的事情，但这并不常见。
A more common practice now is to use a wsdl2java tool to generate a client API from a WSDL description of the service. That will give you a nice, clean, API to call.
现在更常见的做法是使用 wsdl2java 工具从服务的 WSDL 描述生成客户端 API。这将为您提供一个漂亮、干净的 API 来调用。
Apache CXFis one place to go for this sort of thing.
Apache CXF是处理此类事情的一个地方。
One proviso is rpc/encoded. If you are dealing with an old service, it might be rpc/encoded, and in that case your best bet is Apache Axis1.x. Everything else has run away from rpc/encoded.
一个附带条件是 rpc/encoded。如果您正在处理旧服务，它可能是 rpc/encoded，在这种情况下，您最好的选择是Apache Axis1.x。其他一切都远离了 rpc/encoded。

The simplest way is soap-ws library: https://github.com/reficio/soap-ws
最简单的方法是soap-ws库：https: //github.com/reficio/soap-ws
SoapClient client = SoapClient.builder()
.endpointUrl("http://rpc.middleearth.com")
.build();
client.post(envelope);
