java - 向请求添加自定义 header 时出现 Axis 2 和 Rampart 问题

Question

<soapenv:Envelope> 
<soapenv:Header>    
      <cor:india>test</cor:india>
     </soapenv:Header>

<soapenv:Body>
.
.
</soapenv:Body>
</soapenv:Envelope>

     OMFactory omFactory =OMAbstractFactory.getOMFactory();
    OMNamespace omNamespace = omFactory.createOMNamespace("http://example.com/...", "cor");
    OMElement header = omFactory.createOMElement("india", omNamespace);
    header.setText("test");
    stub._getServiceClient().addHeader(header);

我想将自定义 header 添加到使用 Axis 2 和城墙的肥皂请求中。但下面是我遇到的异常

如果您尝试使用此处提供的提示添加 header Example Custom Headers当您使用壁垒进行交战时，您可能会面临上述问题。

解决方案是在 META-INF 中添加您自己的 module.xml 并在您要添加自定义 header 的位置添加输出流

<module name="test" class="exampleClass">

    <OutFlow>

            <handler name="handle" class="exampleClass">
                <order phase="Security"  />
            </handler>
        </OutFlow>
</module>

================================================== =====================================

public class exampleClass AbstractHandler implements org.apache.axis2.modules.Module {

public InvocationResponse invoke(MessageContext ctx) throws AxisFault {

SOAPEnvelope env = ctx.getEnvelope();
SOAPHeader hdr = env.getHeader();

SOAPFactory factory = (SOAPFactory) env.getOMFactory();

OMNamespace ns = factory.createOMNamespace("http://google.com", "cor");

//SOAPHeader head = factory.createSOAPHeader(env);

hdr.addHeaderBlock("india", ns).setText("value here");

return InvocationResponse.CONTINUE;
}


public void applyPolicy(Policy arg0, AxisDescription arg1) throws AxisFault {
    // TODO Auto-generated method stub

}

public boolean canSupportAssertion(Assertion arg0) {
    // TODO Auto-generated method stub
    return false;
}

public void engageNotify(AxisDescription arg0) throws AxisFault {
    // TODO Auto-generated method stub

}

public void init(ConfigurationContext arg0, AxisModule arg1) throws AxisFault {
    // TODO Auto-generated method stub

}

public void shutdown(ConfigurationContext arg0) throws AxisFault {
    // TODO Auto-generated method stub

} }

在客户端中，在城墙之前启用您的模块，例如

Options options = serviceClient.getOptions();
serviceClient.engageModule("test");

options.setProperty(RampartMessageData.KEY_RAMPART_POLICY,loadPolicy("policy.xml"));
serviceClient.engageModule("rampart");
