java - 当运行使用 Apache Camel 开发的 jar 时，如何修复路由标记中的 SAXParseException？

Question

同事们，我有 Camel 上下文文件:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/spring"
       xsi:schemaLocation="
          http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
          http://camel.apache.org/schema/spring
          http://camel.apache.org/schema/spring/camel-spring-2.0.0.xsd">

          <bean id="myFilter" class="com.ac.am.CamelComp.CurrentDateFileFilter"/>
    <bean id="xsdProcessor" class="com.ac.am.CamelComp.MessProcessor"/>
    <bean id="startPolicy" class="org.apache.camel.routepolicy.quartz2.CronScheduledRoutePolicy">
        <property name="routeStartTime" value="0 0/5 * ? * 1-6 *" />
    </bean>

    <camel:camelContext xmlns="http://camel.apache.org/schema/spring">
          <route id="uploadFromFtp" routePolicyRef="startPolicy">
            <camel:from uri="sftp://
            &amp;throwExceptionOnConnectFailed=true
            &amp;consumer.delay=10000
            &amp;recursive=true"/>
            <camel:to uri="bean:xsdProcessor"/>
            <camel:to uri="file:sftp-inbound"/>
        </route>
    </camel:camelContext>
</beans>

我使用 mvn clean compile assembly:single 编译了 pogramm 。当我运行 jar 时，我收到下一个堆栈跟踪:

第 23 行是: <route id="uploadFromFtp" routePolicyRef="startPolicy">

你能帮忙解决一下吗？谢谢。

更新

camel已添加到route ，但没有什么改变

<camel:camelContext xmlns="http://camel.apache.org/schema/spring">
          <camel:route id="uploadFromFtp" routePolicyRef="startPolicy">
            <camel:from uri="sftp:......
            &amp;throwExceptionOnConnectFailed=true
            &amp;consumer.delay=10000
            &amp;recursive=true"/>
            <camel:to uri="bean:xsdProcessor"/>
            <camel:to uri="file:sftp-inbound"/>
        </camel:route>
    </camel:camelContext>

堆栈:

Caused by: org.xml.sax.SAXParseException; lineNumber: 24; columnNumber: 72; cvc-complex-type.3.2.2: Attribute 'routePolicyRef' is not allowed to appear in element 'camel:route'.

lineNumber: 24;是 <camel:camelContext xmlns="http://camel.apache.org/schema/spring">

Answer 1

您的camel命名空间xmlns:camel="http://camel.apache.org/schema/spring" 映射到架构 http://camel.apache.org/schema/spring/camel-spring-2.0.0.xsd 的 2.0.0 版本(通过 xsi:schemaLocation)，尚未定义 routePolicyRef 属性。

看来这个属性只在 2.1.0 中添加过

...
<xs:attribute name="routePolicyRef" type="xs:string"/> 
...

因此，出现错误。

您可以尝试更新您的 xsi:schemaLocation 以指向正确的架构版本(2.1.0 或更高版本)，前提是您使用的是框架本身的正确版本。
