在使用Spring-WS时，如何在客户端动态设置自定义HTTP头（而不是SOAP头）？
public class AddHttpHeaderInterceptor implements ClientInterceptor {
public boolean handleFault(MessageContext messageContext)
throws WebServiceClientException {
return true;
}
public boolean handleRequest(MessageContext messageContext)
throws WebServiceClientException {
TransportContext context = TransportContextHolder.getTransportContext();
HttpComponentsConnection connection =(HttpComponentsConnection) context.getConnection();
connection.addRequestHeader("name", "suman");
return true;
}
public boolean handleResponse(MessageContext messageContext)
throws WebServiceClientException {
return true;
}
}
配置：
<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
...
<property name="interceptors">
<list>
<bean class="com.blah.AddHttpHeaderInterceptor" />
</list>
</property>
</bean>
ClientInterceptor非常适合静态标头值。但是，当每个请求应该应用不同的值时，不可能使用它。在那种情况下WebServiceMessageCallback是有帮助的：
final String dynamicParameter = //...
webServiceOperations.marshalSendAndReceive(request,
new WebServiceMessageCallback() {
void doWithMessage(WebServiceMessage message) {
TransportContext context = TransportContextHolder.getTransportContext();
CommonsHttpConnection connection = (CommonsHttpConnection) context.getConnection();
PostMethod postMethod = connection.getPostMethod();
postMethod.addRequestHeader( "fsreqid", dynamicParameter );
}
}
使用spring integration 3和spring integration-ws时，可以使用以下代码处理请求：
public boolean handleRequest(MessageContext messageContext)
throws WebServiceClientException {
TransportContext context = TransportContextHolder.getTransportContext();
HttpUrlConnection connection = (HttpUrlConnection) context
.getConnection();
connection.getConnection().addRequestProperty("HEADERNAME",
"HEADERVALUE");
return true;
}
Interceptor可以通过以下方式连接到出站网关：
<ws:outbound-gateway ...
interceptor="addPasswordHeaderInterceptor" >
</ws:outbound-gateway>
<bean id="addPasswordHeaderInterceptor class="com.yourfirm.YourHttpInterceptor" />
使用java 1.8的示例方法：如何添加HTTP标头：
public void executeObjectWebservice(String id) {
ExecuteObject request = new ExecuteObject();
getWebServiceTemplate().marshalSendAndReceive("http://url/webservice-test/uc4ws",
new ObjectFactory().createExecuteObject(request), new WebServiceMessageCallback() {
public void doWithMessage(WebServiceMessage message) throws IOException {
TransportContext context = TransportContextHolder.getTransportContext();
HttpUrlConnection connection = (HttpUrlConnection) context.getConnection();
connection.addRequestHeader("ID", id);
}
});
}
说明：使用getWebServiceTemplate（）。marshalSendAndReceive，如下所示：https://spring.io/guides/gs/consuming-web-service/
第一个参数是URI，第二个是与请求一起发送的对象。作为第三个参数，您可以添加为功能
new WebServiceMessageCallback()
你重写public void doWithMessage的地方。在发送请求之前调用此方法。您可以在其中访问该消息并添加请求标题
TransportContext context = TransportContextHolder.getTransportContext();
HttpUrlConnection connection = (HttpUrlConnection) context.getConnection();
connection.addRequestHeader("ID", id);
Spring的webServiceTemplate.marshalSendAndReceive（request）方法在内部使用HttpComponentsMessageSender通过网络发送SOAP消息，这进一步使用WebServiceConnection与服务器建立http连接。您所要做的就是编写自己的自定义HttpComponentsMessageSender并在postMethod中设置cookie。
自订发件人代码：
package com.swap.ws.sender;
import java.io.IOException;
import java.net.URI;
import javax.annotation.Resource;
import org.apache.http.client.methods.HttpPost;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Service;
import org.springframework.ws.transport.WebServiceConnect ion;
import org.springframework.ws.transport.http.HttpComponen tsConnection;
/**
*
* @author swapnil Z
*/
@Service("urlMessageSender")
public class CustomHttpComponentsMessageSender extends
org.springframework.ws.transport.http.HttpComponen tsMessageSender {
private static Logger _logger = Logger.getLogger("");
@Override
public WebServiceConnection createConnection(URI uri) throws IOException {
String cookie = null;
HttpComponentsConnection conn = (HttpComponentsConnection) super
.createConnection(uri);
HttpPost postMethod = conn.getHttpPost();
cookie = "<Your Custom Cookie>";
postMethod.addHeader("Cookie", cookie);
return conn;
}
}
弹簧配置：
<bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMe ssageFactory" />
<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshalle r">
<property name="contextPath" value="com.swap.provision" />
</bean>
<bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServi ceTemplate">
<constructor-arg ref="messageFactory" />
<property name="marshaller" ref="marshaller"></property>
<property name="unmarshaller" ref="marshaller"></property>
<property name="messageSender" ref="urlMessageSender"/>
<property name="defaultUri" value=<Server URL> />
</bean>
在此之后，我只需获取bean webServiceTemplate并调用marshalSendAndReceive方法。因此，每个请求都会在进行HTTP调用之前设置自定义cookie。
实际上，它是@Tomasz答案的更新版本，但提供了一个新的Spring-WS API，Java 8快捷方式，并且关注如何使用单独的方法创建WebServiceMessageCallback实例。
我相信它更加明显和自给自足。
final class Service extends WebServiceGatewaySupport {
/**
* @param URL the URI to send the message to
* @param payload the object to marshal into the request message payload
* @param headers HTTP headers to add to the request
*/
public Object performRequestWithHeaders(String URL, Object payload, Map<String, String> headers) {
return getWebServiceTemplate()
.marshalSendAndReceive(URL, payload, getRequestCallback(headers));
}
/**
* Returns a {@code WebServiceMessageCallback} instance with custom HTTP headers.
*/
private WebServiceMessageCallback getRequestCallback(Map<String, String> headers) {
return message -> {
TransportContext context = TransportContextHolder.getTransportContext();
HttpUrlConnection connection = (HttpUrlConnection)context.getConnection();
addHeadersToConnection(connection, headers);
};
}
/**
* Adds all headers from the {@code headers} to the {@code connection}.
*/
private void addHeadersToConnection(HttpUrlConnection connection, Map<String, String> headers){
headers.forEach((name, value) -> {
try {
connection.addRequestHeader(name, value);
} catch (IOException e) {
e.printStackTrace(); // or whatever you want
}
});
}
}
以下片段已在Spring 4.0中测试过。它将WebServiceMessageCallback附加到org.springframework.ws.client.core.WebServiceTemplate
final String DYNAMICVALUE = "myDynamo";
WebServiceMessageCallback wsCallback = new WebServiceMessageCallback() {
public void doWithMessage(WebServiceMessage message) {
try {
SoapMessage soapMessage = (SoapMessage)message;
SoapHeader header = soapMessage.getSoapHeader();
header.addAttribute(new QName("myHeaderElement"), DYNAMICVALUE);
} catch (Exception e) {
e.printStackTrace();
}
}
};
JAXBElement<MyWsResponse> response = (JAXBElement<MyWsResponse>)
wsTemplate.marshalSendAndReceive(MyWsOP, wsCallback);
