Java 如何从每个SOAP响应/请求中添加/读取自定义头

我必须在SOAP响应中添加一个自定义头，并从SOAP请求中读取头 到目前为止，我所做的是指这些链接，如下所示

Web服务类：

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService()
@HandlerChain(name = "SoapHandler", file = "soaphandler.xml")
public class FooService {

    @WebMethod()
    public String sayHello(String name) {
        System.out.println("Hello: " + name);
        return "Hello " + name + "!";
    }
}

package com.webservice;

import java.util.Set;
import java.util.logging.Logger;
import javax.xml.namespace.QName;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;

public class SoapHandler implements SOAPHandler<SOAPMessageContext> {

    private static final Logger LOGGER = Logger.getLogger(SoapHandler.class.getName());

    @Override
    public void close(MessageContext arg0) {
        System.out.println("Colse Method");
        LOGGER.info("Close Method");
    }

    @Override
    public boolean handleFault(SOAPMessageContext arg0) {
        System.out.println("handleFault Method");
        LOGGER.info("handleFault Method");
        return false;
    }

    @Override
    public boolean handleMessage(SOAPMessageContext arg0) {
        System.out.println("handleMessage Method");
        LOGGER.info("handleMessage Method");
        return false;
    }

    @Override
    public Set<QName> getHeaders() {
        System.out.println("getHeaders Method");
        LOGGER.info("getHeaders Method");
        return null;
    }
}

SOAP处理程序类：

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService()
@HandlerChain(name = "SoapHandler", file = "soaphandler.xml")
public class FooService {

    @WebMethod()
    public String sayHello(String name) {
        System.out.println("Hello: " + name);
        return "Hello " + name + "!";
    }
}

package com.webservice;

import java.util.Set;
import java.util.logging.Logger;
import javax.xml.namespace.QName;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;

public class SoapHandler implements SOAPHandler<SOAPMessageContext> {

    private static final Logger LOGGER = Logger.getLogger(SoapHandler.class.getName());

    @Override
    public void close(MessageContext arg0) {
        System.out.println("Colse Method");
        LOGGER.info("Close Method");
    }

    @Override
    public boolean handleFault(SOAPMessageContext arg0) {
        System.out.println("handleFault Method");
        LOGGER.info("handleFault Method");
        return false;
    }

    @Override
    public boolean handleMessage(SOAPMessageContext arg0) {
        System.out.println("handleMessage Method");
        LOGGER.info("handleMessage Method");
        return false;
    }

    @Override
    public Set<QName> getHeaders() {
        System.out.println("getHeaders Method");
        LOGGER.info("getHeaders Method");
        return null;
    }
}

处理程序链配置：

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService()
@HandlerChain(name = "SoapHandler", file = "soaphandler.xml")
public class FooService {

    @WebMethod()
    public String sayHello(String name) {

        return "Hello " + name + "!";

使用handleMessage中的上下文参数

arg0.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

检查retunred布尔值，将消息标识为request/response

是否配置了处理程序链？@balaji krishnan是的，我已按照Link2中的给定配置了处理程序链，我的SOAP处理程序正在工作，但当请求传入和传出时，handleMessage（）方法会执行两次，现在的问题是如何区分传入请求和传出响应？我使用的代码与您提到的对象bOutbound=messageContext.get（messageContext.MESSAGE\u OUTBOUND\u属性）相同；这意味着当它返回Boolean.TRUE值时，它是响应；当Boolean.FALSE值时，它是请求。是这样吗？是的，你是对的。javadoc here：嘿，谢谢，这对我来说很有效，但还有一件事，我如何从处理程序链配置中排除一些方法？i、 假设我在FooService类中还有一个方法是sayHey（），我想从这个SoapHandler类中排除这个方法？我认为你做不到。。这些是在SOAPHandler和SOAPMessageContext接口中定义的方法。这不是建议的方法，但可能是您可以创建另一个覆盖所有方法的类，并且在所需的类中仅扩展它并覆盖getMessage。与通常的接口一样，您需要以某种方式提供实现—您可以在服务器端和客户端同时实现处理程序。如果要在所有请求头中包含某些内容，请在客户端处理程序中执行，然后提取头内容并在服务器端处理程序中验证。。就像我们在网络应用中使用的过滤器一样
