在 JAXWS 服务器端检索 Soap 标头

您可以从 in 中读取 soap 标头，然后通过 中的属性将这些值传递给您的实现。SOAPMessageContextSOAPHandler@WebServiceMessageContext

虽然 API 特定于 JAX-WS 参考实现，但以下样本应可移植到任何 JAX-WS 运行时。HeaderList

例：

网络服务 impl：

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（处理程序.xml，与 文件位于同一包中）：SampleServiceImpl.java

如果收到错误“必须了解标头”，请重写该方法。getHeaders()

@Override

        final QName securityHeader = new QName(
                "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd",
                "Security",
                "wsse");


        final HashSet headers = new HashSet();
        headers.add(securityHeader);

        // notify the runtime that this is handled
        return headers;
    }
