问题
我正在接管java Web服务客户端的开发,为了测试进化,我必须从远程Web服务服务器(嵌入在tomcat实例中运行的Apache Axis2中)中请求一个方法.
首先,我使用服务器提供的WSDL通过SOAP UI请求了该方法.它工作正常.
现在我尝试通过我的Java Web服务客户端请求该方法,但我无法连接到服务器,即使使用SOAP UI测试证明一切都很好.
java Web服务客户端依赖于Spring-WS.
从客户端调用Web服务
// Setting the kycScoreRequest
...
// Trying to connect and to get the kycScoreResponse
KycScoreResponse kycScoreResponse = (KycScoreResponse) getWebServiceTemplate().marshalSendAndReceive(kycScoreRequest);
产生的错误

假设1：我使用正确的Web服务URL吗？
我确信Spring给了正确的URL,因为它与我接手代码之前是一样的,并没有改变wsdl和服务器(我们的客户从不抱怨,它对他有用,但从来没有在我们的工作中的机器.所以不要问我之前的开发人员如何测试它,虽然它不起作用,因为idk)：
WebServiceGatewaySupport.setDefaultUri("http://82.36.138.182:8080/axis2/services/KYCService01.KYCService01HttpSoap11Endpoint/")
我在WSDL中有以下内容：
我也尝试将EPR作为网址,但它并没有改变任何东西：
WebServiceGatewaySupport.setDefaultUri("http://82.36.138.182:8080/axis2/services/KYCService01")
假设2：它是我落后的代理吗？
然后,我认为错误肯定是由于我所支持的代理引起的.实际上,当我尝试编写一小段代码来连接到wsdl url时,起初我无法得到“连接超时”.为了解决这个问题,我将代理设置为java System属性,允许我现在从Web服务客户端访问wsdl.
设置代理
System.setProperty("http.proxyHost","
连接到WSDL URL
URL wsdlAddress = null;
HttpURLConnection connection = null;
wsdlAdress = new URL("
不幸的是,当我尝试使用我的代理集调用Web服务服务器时,我仍然有与上面提到的完全相同的错误.现在我已经不在乎了.我的Java客户端如何可以访问Web服务WSDL而不是其方法？
(编辑)假设3：这是http标题吗？
由于膜拦截器,我从SOAP UI和WS客户端拦截了HTTP msg.查看标题：
SOAP UI
POST http://82.36.138.182:8080/axis2/services/KYCService01.KYCService01HttpSoap11Endpoint/ HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
SOAPAction: "urn:kycScore"
Content-Length: 1301
Host: 84.37.138.182:8080
Proxy-Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
WS客户端(目标URL是SOAP UI模拟服务器,因为很明显,如果我使用URL我真的尝试连接到没有发送任何内容,因此没有任何内容可以拦截)
POST /mock HTTP/1.1
Accept-Encoding: gzip
Accept: text/xml,text/html,image/gif,image/jpeg,*; q=.2,*/*; q=.2
SOAPAction: ""
Content-Type: text/xml; charset=utf-8
Content-Length: 1032
Host: localhost:8088
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.3 (Java/1.8.0_101)
我对http头文件一无所知,但主要区别似乎是SOAPAction.我将我的ws客户端消息的SOAPAction属性设置为与SOAP UI相同的值,但它没有改变任何东西.
public Object marshalWithSoapActionHeader(KycScore o) {
return getWebServiceTemplate().marshalSendAndReceive(o,new WebServiceMessageCallback() {
public void doWithMessage(WebServiceMessage message) {
((SoapMessage) message).setSoapAction("urn:kycScore");
}
});
}
否则,我们可以在User-Agent属性中看到的java版本是否重要？ (编辑)我不这么认为,因为我试图使用1.6 jre并且版本确实在User-Agent属性中更改但我仍然有相同的错误.
