Question

在以前的si版本中（si 2.11是特定的和spring 3.1.1）可以覆盖getStandardRequestHeaderNames以在si消息头中包含Additional Application特定对象。我们的应用程序依赖于此功能（可能是错误的），以覆盖此方法并提供下游传输的自定义POJO，包括许多分离器，聚合器等。应用程序使用ws入站网关并使用header-mapper属性指定自定义soap标头映射器。

有关为何无法覆盖getStandardRequestHeaderNames的原因的任何线索？

需要一些建议我如何将其迁移到当前的spring版本。要求是从soapHeader中提取元素并将它们映射到SI消息头作为POJO并将其发送到下游。所有帮助表示赞赏。

请分享一些代码你想怎么看？

也许您可以实现自己的SoapHeaderMapper并将其注入WS Inbound Gateway？

您仍然可以重复使用逻辑并复制/粘贴DefaultSoapHeaderMapper中的标准行为。

<强>更新

用于演示如何手动添加用户定义标头的测试用例：

@Test
public void testCustomSoapHeaderMapper() {
    DefaultSoapHeaderMapper mapper = new DefaultSoapHeaderMapper() {

        @Override
        protected Map<String, Object> extractUserDefinedHeaders(SoapMessage source) {
            Map<String, Object> headers = super.extractUserDefinedHeaders(source);
            headers.put("foo", "bar");
            return headers;
        }
    };

    mapper.setRequestHeaderNames("*");

    SoapMessage soapMessage = mock(SoapMessage.class);

    Map<String, Object> headers = mapper.toHeadersFromRequest(soapMessage);
    assertTrue(headers.containsKey("foo"));
    assertEquals("bar", headers.get("foo"));
}

Spring integeration DefaultSoapHeaderMapper - getStandardRequestHeaderNames - 覆盖
