嗨，对不起，我的知识很少，但我是使用弹簧和骆驼的初学者。我正在尝试制作一个简单的camelContext bean，它将消息从端点路由到另一个称为smartlighting 的spring bean。问题是每当我初始化 camelContext 甚至在 xml 中为空时，我都会得到这个奇怪的“函数参数不兼容”异常。

我正在使用 spring 3.0 & camel 2.10.3 & tomcat server v7.0

我的spring 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"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
    http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd
    "> 

<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>

每当我运行该项目时，我都会遇到此异常

您可以在上下文文件中将骆驼命名空间设置为默认命名空间，并使用 beans 别名来引用 spring beans。
例如：

<?xml 版本="1.0" 编码="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>
