17.13. 如何在 PAYLOAD 模式中获取和设置 SOAP 标头

我们已展示了如何在 PAYLOAD 模式中以 PAYLOAD 模式访问 SOAP 消息作为 CxfPayload 对象，该部分 是 How to handle the camel-cxf endpoint in PAYLOAD data format。

获取 CxfPayload 对象后，您可以调用 CxfPayload.getHeaders （）方法，该方法返回 DOM Elements (SOAP 标头)列表。

例如，请参阅 CxfPayLoadSoapHeaderTest ：

from(getRouterEndpointURI()).process(new Processor() {
    @SuppressWarnings("unchecked")
    public void process(Exchange exchange) throws Exception {
        CxfPayload<SoapHeader> payload = exchange.getIn().getBody(CxfPayload.class);
        List<Source> elements = payload.getBodySources();
        assertNotNull(elements, "We should get the elements here");
        assertEquals(1, elements.size(), "Get the wrong elements size");

        Element el = new XmlConverter().toDOMElement(elements.get(0));
        elements.set(0, new DOMSource(el));
        assertEquals("http://camel.apache.org/pizza/types",
                el.getNamespaceURI(), "Get the wrong namespace URI");

        List<SoapHeader> headers = payload.getHeaders();
        assertNotNull(headers, "We should get the headers here");
        assertEquals(1, headers.size(), "Get the wrong headers size");
        assertEquals("http://camel.apache.org/pizza/types",
                ((Element) (headers.get(0).getObject())).getNamespaceURI(), "Get the wrong namespace URI");
        // alternatively you can also get the SOAP header via the camel header:
        headers = exchange.getIn().getHeader(Header.HEADER_LIST, List.class);
        assertNotNull(headers, "We should get the headers here");
        assertEquals(1, headers.size(), "Get the wrong headers size");
        assertEquals("http://camel.apache.org/pizza/types",
                ((Element) (headers.get(0).getObject())).getNamespaceURI(), "Get the wrong namespace URI");

    }

})
.to(getServiceEndpointURI());

您还可以使用与子选择 " How to get and set SOAP headers in POJO 模式"中所述的方法一样设置或获取 SOAP 标头。因此，您可以使用标头 "org.apache.cxf.headers.Header.list" 来获取和设置 SOAP 标头列表。这也意味着，如果您有一个从一个 Camel-cxf 端点转发到另一个 Camel-cxf 端点的路由(SOAP Client Camel CXF 服务)，现在也会将 SOAP 客户端发送的 SOAP 标头转发到 CXF 服务。如果您不想转发这些标头，则必须在 Camel 标头 "org.apache.cxf.headers.Header.list" 中删除它们。
