第一步：调整客户端，增加请求头
1.修改StudentServiceSoapBindingStub类，增加一个方法createAuthInfo()，内容如下：
/**
*
* 为soap报文添加自定义的用户授权信息，这里为用户名和密码
*
* @return SOAPHeaderElement对象
*/
public SOAPHeaderElement createAuthInfo() {
SOAPHeaderElement header = new SOAPHeaderElement(
"http://www.csdn.com/axis/StudentService", "AuthHeadersInfo");
header.setNamespaceURI("http://www.csdn.com/axis/StudentService");
try {
header.addChildElement("userName").setValue("zhangsan");
header.addChildElement("password").setValue("123pwd");
} catch (Exception e) {
e.printStackTrace();
}
return header;
}
2.为soap报文增加请求头，找到StudentServiceSoapBindingStub类的createCall方法，在return _call;之前添加一句：_call.addHeader(createAuthInfo());// 增加用户授权信息
内容如下：
_call.addHeader(createAuthInfo());// 增加用户授权信息
StudentServiceSoapBindingStub类的完整内容如下

/**

public SOAPHeaderElement createAuthInfo() {
SOAPHeaderElement header = new SOAPHeaderElement(
"http://www.csdn.com/axis/StudentService", "AuthHeadersInfo");
header.setNamespaceURI("http://www.csdn.com/axis/StudentService");
try {
header.addChildElement("userName").setValue("zhangsan");
header.addChildElement("password").setValue("123pwd");
} catch (Exception e) {
e.printStackTrace();
}
return header;
}
}
第二步：修改服务端代码
回到StudApp中，修改我们的StudAppUtil的invokeInnerService方法，增加如下代码：
//增加验证用户授权信息 BEGIN
MessageContext msgContext = MessageContext.getCurrentContext();
try {
Iterator<SOAPElement> iterator = msgContext.getMessage()
.getSOAPHeader().getChildElements();
while (iterator.hasNext()) {
SOAPElement ele = iterator.next();
Iterator<SOAPElement> iterator2 = ele.getChildElements();
while (iterator2.hasNext()) {
SOAPElement element = iterator2.next();
String Name = element.getNodeName();
String value = element.getValue();
System.out.println("Name=" + Name + ",Value=" + value);
}
}
} catch (SOAPException e) {
e.printStackTrace();
}
//增加验证用户授权信息 END
StudAppUtil类的完整代码如下:
package com.csdn.utils;
import java.util.Iterator;
import java.util.Map;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPException;
import org.apache.axis.MessageContext;
/**
*
* 公共学生信息工具类
*
* @author Jack_David
*
*/
public class StudAppUtil {
/**
*
* 调用内部服务
*
* @param studentNo
* 学生学号
* @param txnCode
* 交易码
* @return 返回交易的结果信息
*/
@SuppressWarnings("unchecked")
public static String invokeInnerService(Map<String, Object> dataMap,
String txnCode) {
String responseInfo = "";
//增加验证用户授权信息 BEGIN
MessageContext msgContext = MessageContext.getCurrentContext();
try {
Iterator<SOAPElement> iterator = msgContext.getMessage()
.getSOAPHeader().getChildElements();
while (iterator.hasNext()) {
SOAPElement ele = iterator.next();
Iterator<SOAPElement> iterator2 = ele.getChildElements();
while (iterator2.hasNext()) {
SOAPElement element = iterator2.next();
String Name = element.getNodeName();
String value = element.getValue();
System.out.println("Name=" + Name + ",Value=" + value);
}
}
} catch (SOAPException e) {
e.printStackTrace();
}
//增加验证用户授权信息 END
if ("getStudentInfo".equals(txnCode)) {
String studentNo = (String) dataMap.get("studentNo");
responseInfo = "学号=" + studentNo + ",姓名=张三,年龄=18,专业=计算机科学";
} else if ("getStudentMarks".equals(txnCode)) {
String studentNo = (String) dataMap.get("studentNo");
String subjectNo = (String) dataMap.get("subjectNo");
responseInfo = "学号=" + studentNo + ",学科号=" + subjectNo + ",成绩=98";
}
return responseInfo;
}
}
第三步：执行客户端程序，发送请求
执行客户端的StudClient的mian方法，发起调用两个接口的请求，观察服务端和客户端的相关信息
客户端正常收到响应，如下图：
服务端收到了客户端发送的用户验证信息，如下图：
第四步：通过TCP\IP Monitor监测报文
我们可以使用Eclipse自带的代理工具TCP\IP Monitor来监测请求及响应报文，思路如下：
1.TCP\IP Monitor监听8080端口，转发到本机的8090端口上去
2.客户端发送报文的时候，将报文发送到8080端口
说明：不会使用TCP\IP Monitor该工具的，请参考链接：https://www.cnblogs.com/liuhongfeng/p/4187572.html?utm_source=tuicool&utm_medium=referral
TCP\IP Monitor工具的配置截图如下：
修改客户端发送的端口
修改StudentServiceImplServiceLocator类的请求发送端口
private java.lang.String StudentService_address = "http://127.0.0.1:8080/StudApp/services/StudentService";
执行客户端的请求
执行StudClient的两个请求，观察TCP\IP Monitor中的抓包信息，可以看到这两次的完整的请求以及相应信息，如下图：
我们把两次请求的报文拿出来单独看，会发现已经包含了我们指定的用户验证信息，如下图：
