16.13. 如何在 PAYLOAD 模式中获取和设置 SOAP 标头

from(getRouterEndpointURI()).process(new Processor() {

        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");
