推荐答案

添加一个处理程序。一种方法如下所示

Add a handler. One way to do it as below

@WebService()
@HandlerChain(file = "FooService-HandlerChain.xml")
public class FooService{
      //your code 
}

然后你的处理程序文件

<handler-chains xmlns="http://java.sun.com/xml/ns/javaee">
  <handler-chain>
  <service-name-pattern xmlns:ns1="yournamespacepattern">ns1:FooService</service-name-pattern>
  <handler>
     <handler-name>HandlerClassName</handler-name>
     <handler-class>packagename.HandlerClassName</handler-class>
  </handler>

然后您的处理程序类

 public class HandlerClassName implements SOAPHandler<SOAPMessageContext>
 {
  public HandlerClassName () {
 }

public Set<QName> getHeaders(){
    return // set of headers;
}


public boolean handleMessage(SOAPMessageContext context)
{
     //handle message
}

}
