Question

我注意到Spring Integration使用了一个属性＆＃34; path＆＃34;在元素＆＃34; inbound-gateway＆＃34;中，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，＆＃34;路径＆＃34;属性不存在：

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＆＃34;接受＆＃34;的列表属性：

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

＆＃34;路径＆＃34;属性不存在于定义中。

效果是我在应用程序开始时出错：

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＆＃34;有罪的＆＃34;部分配置：

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

这是不一致的！也许缺少某些东西？

Answer 1

当您没有在 pom.xml 中放置足够的依赖项时，通常会发生这种情况。所以这个具体问题的答案是添加以下代码

<dependency>
  <groupId>org.springframework.integration</groupId>
  <artifactId>spring-integration-http</artifactId>
</dependency>

那么您的编译器将不会使用在线 xsd 验证您的 xml，而是使用隐藏在您刚刚添加的依赖项 jar 中的本地 xsd 进行验证。

我不想在互联网上搜索您正在展示XSD的Spring Integration版本，但这确实已经足够老了，当前和以前的许多版本中肯定存在path属性：

<xsd:attributeGroup name="inboundCommonAttributes">
    <xsd:attribute name="path" type="xsd:string">
        <xsd:annotation>
            <xsd:documentation>
                Comma-separated URI paths (e.g., /orderId/{order}).
                Ant-style path patterns are also supported (e.g. /myPath/*.do).
            </xsd:documentation>
        </xsd:annotation>
    </xsd:attribute>

请考虑一下，在Eclipse中打开Spring Nature，让它从项目中的jar而不是从Internet读取XSD。
