Spring Integration HTTP:元素"inbound-gateway“的属性"path”不一致

Question

我注意到Spring Integration在元素"inbound-gateway“中使用了属性"path”，如文档中所述：

http://docs.spring.io/spring-integration/reference/html/http.html#_request_mapping_support

但是在HTTP集成的XSD中，"path“属性并不存在：

http://www.springframework.org/schema/integration/http/spring-integration-http.xsd

<xsd:element name="inbound-gateway">
    <xsd:complexType>
        <xsd:annotation>
            <xsd:documentation>Defines an inbound HTTP-based Messaging Gateway.</xsd:documentation>
        </xsd:annotation>
        <xsd:complexContent>
            <xsd:extension base="gatewayType">
                <xsd:attribute name="name" type="xsd:string"/>
                <xsd:attribute name="extract-reply-payload" type="xsd:string" default="true"/>
                <xsd:attribute name="supported-methods" type="xsd:string"/>
                <xsd:attribute name="view" type="xsd:string">
                    <xsd:annotation>
                        <xsd:appinfo>
                            <tool:annotation kind="ref">
                                <tool:expected-type type="org.springframework.web.servlet.View"/>
                            </tool:annotation>
                        </xsd:appinfo>
                    </xsd:annotation>
                </xsd:attribute>
                <xsd:attribute name="request-mapper" type="xsd:string">
                    <xsd:annotation>
                        <xsd:appinfo>
                            <tool:annotation kind="ref">
                                <tool:expected-type type="org.springframework.integration.http.InboundRequestMapper"/>
                            </tool:annotation>
                        </xsd:appinfo>
                    </xsd:annotation>
                </xsd:attribute>
                <xsd:attribute name="request-key" type="xsd:string"/>
                <xsd:attribute name="reply-key" type="xsd:string"/>
                <xsd:attribute name="reply-timeout" type="xsd:string"/>
            </xsd:extension>
        </xsd:complexContent>
    </xsd:complexType>
</xsd:element>

这似乎是“接受”属性的列表：

name
extract-reply-payload
supported-methods
view
request-mapper
request-key
reply-key
reply-timeout

"path“属性在定义中不存在。

结果是我在应用程序开始时出现了一个错误：

org.xml.sax.SAXParseException; lineNumber: 71; columnNumber: 53; cvc-complex-type.3.2.2: Attribute "path" is not allowed to appear in element "int-http:inbound-gateway".

这是配置的“被牵连”部分：

<int-http:inbound-gateway request-channel="receiveChannel"
                      path="/receiveGateway"
                      supported-methods="POST"/>

这是不一致的！也许有什么东西遗漏了？
