Spring-WS:肥皂故障未识别为故障

Spring-WS : Soap fault not identified as Fault

我正在使用 Spring-WS,当我通过 webServiceTemplate 的 marshalSendAndReceive 调用 Web 服务时,我收到错误代码为 500 的 SOAP 错误。不幸的是,响应没有被识别为 SOAP 错误(它抛出 WebServiceTransportException)。理论上,当有错误响应时,WebServiceTemplate 抛出一个WebServiceTransportException 如果错误代码与2xx 不同,除非 http 错误是500 并且内容是soap 错误。这是我收到的回复中的一个示例:

    HTTP/1.1 500 Internal Server Error[\r][\n]"
Content-Length: 887[\r][\n]"
Connection: keep-alive[\r][\n]"

有谁知道为什么会这样?有没有办法将其视为 SOAP 故障?

我深入研究了 AbstractHttpSenderConnection 中的 hasFault 方法(将调用该方法来确定错误是否是 soap 错误),我看到了该方法的下一个代码:

/*
 * Faults
 */

public final boolean hasFault() throws IOException {
    return HttpTransportConstants.STATUS_INTERNAL_SERVER_ERROR == getResponseCode() && isXmlResponse();
}

/** Determine whether the response is a XML message. */
private boolean isXmlResponse() throws IOException {
    Iterator<String> iterator = getResponseHeaders(HttpTransportConstants.HEADER_CONTENT_TYPE);
    if (iterator.hasNext()) {
        String contentType = iterator.next().toLowerCase();
        return contentType.indexOf("xml") != -1;
    }
    return false;
}

这意味着,必须有一个 ContentType = xml 的 http header,我调用的 Web 服务没有设置它。我现在必须研究如何在 Web 服务模板中评估错误之前在响应中设置 header。

WebServiceTemplate 中的 checkConnectionForFault 属性 应该可以解决这个问题。
