java如何调用webservice接口？

Java通过WSDL文件来调用webservice直接调用模式如下：

import java.util.Date;

import java.text.DateFormat;

import org.apache.axis.client.Call;

import org.apache.axis.client.Service;

import javax.xml.namespace.QName;

import java.lang.Integer;

import javax.xml.rpc.ParameterMode;

public class caClient {

public static void main(String[] args) {

try {

String endpoint = "http://localhost:8080/ca3/services/caSynrochnized?wsdl";

//直接引用远程的wsdl文件

//以下都是套路 

Service service = new Service();

Call call = (Call) service.createCall();

call.setTargetEndpointAddress(endpoint);

call.setOperationName("addUser");//WSDL里面描述的接口名称

call.addParameter("userName", org.apache.axis.encoding.XMLType.XSD_DATE,

javax.xml.rpc.ParameterMode.IN);//接口的参数

call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//设置返回类型  

String temp = "测试人员";

String result = (String)call.invoke(new Object[]{temp});

//给方法传递参数，并且调用方法

System.out.println("result is "+result);

}

catch (Exception e) {

System.err.println(e.toString());

}

}

}
