简单地使用Java中的Web服务 [英] Simply consuming a web service in Java

问题描述

我有一个非常简单的SOAP Web服务，我需要从Java客户端使用它。在不使用任何第三方库的情况下，最简单的方法是什么？要求是在每次调用ws之前从web.xml读取主机和端口。

I have a very simple SOAP web service that I need to consume from a Java client. What is the easiest way to accomplish this without using any third party libraries? A requirement is that the host and port is read from the web.xml before every call to the ws.

推荐答案

我可以推荐你CXF库。使用它，您将有几个调用Web服务的选项：

I can recommend you CXF library. Using it you will have several options for calling web services:

1. 使用动态代理用于调用（不需要使用wsdl2java创建Java存根）。

1. Use dynamic proxy for calling (don't need to make Java stubs using wsdl2java).

DynamicClientFactory dcf = DynamicClientFactory.newInstance();
Client client = dcf.createClient("http://admin:password@localhost:8080"+
                                 "/services/MyService?wsdl");
Object[] a = client.invoke("test", "");
System.out.println(a);

使用从WSDL生成的Java存根，使用wsdl2java。

Using Java stub generated from WSDL, using wsdl2java.

如果你的服务器是使用CXF创建的，你可以直接重用你的接口代码（而不是在你的界面创建的WSDL上使用wsdl2java！）

If your server was created using CXF you can reuse your interface code directly (instead of using wsdl2java on the WSDL which was created from your interface!)

对于＃2和＃3，以下代码举例说明了CXF的用法：

For both #2 and #3, the following code exemplifies the CXF usage:

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setAddress("http://admin:password@localhost:8080/services/MyService");
factory.setServiceClass(ITest.class);
ITest client = (ITest) factory.create();
client.test();
