Question

请原谅我的小知识，但我是初学者，使用弹簧和骆驼。我正在尝试创建一个简单的camelContext bean，它将消息从端点路由到另一个名为smartlighting的spring bean。问题是每当我初始化camelContext甚至是xml中的空的时候我都会得到这个奇怪的“函数不兼容的参数”异常。

我正在使用spring 3.0＆amp;骆驼2.10.3＆amp; tomcat server v7.0

我的春天xml如图所示：

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

    "> 

<camelContext id="camelcontext" xmlns="http://camel.apache.org/schema/spring">
<route streamCache="true">
   <from uri="jetty:http://192.168.1.99:1989/sample/endpoint"/>
   <bean ref="smartlighting" method="test"/>
</route>   
</camelContext>


<bean id="smartlighting" class="com.example.smartlighting.SmartLightingApp" init-method="init"/>

</beans>

每当我运行项目时，我都会遇到此异常

您可以将camel命名空间作为上下文文件中的默认命名空间，并使用bean别名来引用spring bean 例如：

<?xml version="1.0" encoding="UTF-8"?>

<beans:beans xmlns="http://camel.apache.org/schema/spring"
    xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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.xsd">


<beans:bean id="smartlighting" class="com.example.smartlighting.SmartLightingApp" init-method="init"/>



<camelContext id="camelcontext" xmlns="http://camel.apache.org/schema/spring">

<route streamCache="true">

   <from uri="{{your}}"/>

   <bean ref="smartlighting" method="test"/>

</route>   

</camelContext>

</beans:beans>

使用spring xml函数camelContext的参数不兼容
