我正在开发用于调度的 Spring + Apache Camel 示例。我创建了applicationContext.xml并为调度添加了<camelContext>详细信息，但是当我只运行我的main方法时。我看到以下错误。不确定XML文件中有什么问题。

参考错误：

尝试修改applicationContext，如下所示：

<beans xmlns="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">

    <camelContext xmlns="http://camel.apache.org/schema/spring">
        <route>
            <from uri="timer://simpleTimer?period=1000" />
            <setBody>
                <simple>Hello from timer at ${header.firedTime}</simple>
            </setBody>
            <to uri="stream:out" />
        </route>
    </camelContext>
</beans>

要运行此代码，您需要在pom.xml中进行以下更改。您应该首先使用spring依赖项，然后按照pom.xml进行操作，然后应用程序将获得spring-beans-4.2.5.RELEASE，它将给出引发者：java.lang.ClassNotFoundException: org.springframework.beans.factory.config.EmbeddedValueResolver。请使用以下建议的订单和

<dependencies>
        <!-- Spring Context -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <!-- Spring JDBC -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <!-- Camel core -->
        <dependency>

            <artifactId>camel-core</artifactId>
            <version>${apache.camel.version}</version>
        </dependency>

        <!-- camel stream -->
        <dependency>
            <groupId>org.apache.camel</groupId>
            <artifactId>camel-stream</artifactId>
            <version>${apache.camel.version}</version>
        </dependency>

        <!-- camel spring -->
        <dependency>
            <groupId>org.apache.camel</groupId>
            <artifactId>camel-spring</artifactId>

        </dependency>

            <artifactId>logback-classic</artifactId> <version>${logback.version}</version> 
            </dependency> -->

        <!-- JUnit -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>${junit.version}</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

并使用更正的

<beans xmlns="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">
    <camelContext xmlns="http://camel.apache.org/schema/spring">
        <route>
            <from uri="timer://simpleTimer?period=1000" />
            <setBody>
                <simple>Hello from timer at ${header.firedTime}</simple>
            </setBody>
            <to uri="stream:out" />
        </route>
    </camelContext>
</beans>

看起来Alexey Yakunin也提出了正确答案。但我明白了

camelContext = SpringCamelContext.springCamelContext(appContext, false);
不推荐使用

方法，Alexey，你知道应该使用什么吗？
