好的,我最近问了一个关于使用Java来使用Web服务的问题,而我遇到了多个编译错误。
我在过去的7个小时里一直试图让这个工作起来,在线进行研究。但是Java Web服务调用有很多不同的风格,这对于像我这样的新手来说几乎不可能为我的场景找到相关信息。
我现在有以下代码,至少编译时没有错误。
进口
import java.util.List;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
代码
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://vogellac2dm.appspot.com/register");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("registrationid", "123456789"));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String line = "";
while ((line = rd.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
e.printStackTrace();
}
现在,我有一个.NET WSDL的URL http://webservices.vm.vmc/ExampleService.asmx?WSDL
我想调用接受5个String参数的方法“AddEmployee”。
所以逻辑上我会:
提前感谢您的帮助。
修改
在没有透露任何详细信息的情况下,我创建了一个我想要调用的示例。这是一个简单服务的WSDL,它有1个方法,接受3个字符串参数,并返回一个字符串。

有许多方法可以为Web服务生成客户端。如果您可以访问wsdl(看起来像你这样做),我建议使用像Apache Axis这样的东西来为你生成客户端类。
http://axis.apache.org/axis/java/index.html
下载Axis后,您可以运行一个简单的命令来生成客户端类:
java org.apache.axis.wsdl.WSDL2Java wsdlName
