我们正在尝试在我们的JAX Web服务中执行安全性实现,并且在标题中传递UserName和Password,如下所示.
<soapenv:Header>
<wsse:Security soapenv:mustUnderstand="0" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<wsse:UsernameToken wsu:Id="Id-8zvykuwmK8yg6dxn3632nQJB" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsse:Username>gears_user</wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">##########</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
在Java中,我们正在尝试检索用户名和密码,但是我们不知道如何做,因为它是Soap Header的一部分,我们之前没有检索到头信息.
.....
@Resource
WebServiceContext wsctx;
public ServiceAvailabilityResponseType inquireGeographicEligibility(ServiceAvailabilityRequestType inquireGeographicEligibilityRequest)
throws WSException
{
HeaderList hl=(HeaderList)wsctx.getMessageContext().get(JAXWSProperties.INBOUND_HEADER_LIST_PROPERTY);
QName security = new QName("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd","Security");
Header hd = hl.get(security,false);
QName userName = new QName("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd","Username");
try
{
System.out.println(hd.readHeader());
System.out.println(hd.getAttribute(userName));
}catch (Exception e) {
System.out.println(e.getMessage());
}
}
解决方法
您可以从SOAPHandler类中的SOAPMessageContext读取soap头,然后通过MessageContext中的属性将值传递给您的@WebService实现.
而HeaderList API特定于JAX-WS参考实现,以下示例应该在任何JAX-WS运行时都可移植.
例：
Web服务含义：
package org.example.sampleservice;
import javax.annotation.Resource;
import javax.jws.HandlerChain;
import javax.jws.WebService;
import javax.xml.ws.WebServiceContext;
@WebService(endpointInterface = "org.example.sampleservice.SampleService")
@HandlerChain(file="handlers.xml")
public class SampleServiceImpl implements SampleService {
@Resource
private WebServiceContext ctx;
@Override
public String sayHello(String name) {
String usernameFromHeader = (String) ctx.getMessageContext().get("USERNAME");
return "Hello,"
+ name
+ " (invoked by "
+ (usernameFromHeader == null ? "[err or no 'Security' header found]"
: usernameFromHeader) + ")";
}
}
处理程序链XML(handlers.xml,与SampleServiceImpl.java相同的包中的文件)：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<javaee:handler-chains
xmlns:javaee="http://java.sun.com/xml/ns/javaee"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<javaee:handler-chain>
<javaee:handler>
<javaee:handler-class>org.example.sampleservice.UsernameTokenHandler</javaee:handler-class>
</javaee:handler>
</javaee:handler-chain>
</javaee:handler-chains>
