WSPasswordCallback
的 passwordType
属性和 password
属性都为null,你只能获得用户名(identifier),一般这里的逻辑是使用这个用户名到数据库中查询其密码,然后再设置到 password
属性,WSS4J会自动比较客户端传来的值和你设置的这个值。你可能会问为什么这里CXF不把客户端提交的密码传入让我们在 ServerPasswordCallbackHandler
中比较呢?这是因为客户端提交过来的密码在SOAP消息中已经被加密为MD5的字符串,如果我们要在回调方法中作比较,那么第一步要做的就是把服务端准备好的密码加密为MD5字符串,由于MD5算法参数不同结果也会有差别,另外,这样的工作CXF 替我们完成不是更简单吗?
根据上面说的,我获取的 password
为 null
,所以这里就不用自己判断密码了,只要验证用户名后,在设置密码就可以自动验证了,代码如下:
public class ServerPasswordCallback implements CallbackHandler { public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException { WSPasswordCallback pc = (WSPasswordCallback) callbacks[0]; String pw = pc.getPassword(); String idf = pc.getIdentifier(); System.out.println("password:"+pw); System.out.println("identifier:"+idf); if(idf.endsWith("admin")){ pc.setPassword("admin"); } } }
