我正在尝试设置我的应用程序以使用 Spring Integration（版本 2.2.0.RELEASE）接收文件。当我启动 Tomcat（部署应用程序的位置）时，我收到以下错误消息。任何人都知道为什么？

我相信上面的错误信息是一个红鲱鱼。在将 spring 集成依赖项添加到 pom 文件并具有 ftp 配置文件之前，Tomcat 已成功启动。

我使用 Java6 和 Tomcat6。我的 FTP 配置文件是：

<?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:int="http://www.springframework.org/schema/integration"
    xmlns:int-ftp="http://www.springframework.org/schema/integration/ftp"
    xsi:schemaLocation="

        <int:queue/>
    </int:channel>

    <bean id="ftpClientFactory"
        class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory">
        <property name="host" value="localhost" />
        <property name="port" value="21" />
        <property name="username" value="user" />
        <property name="password" value="password" />
    </bean>

    <int-ftp:inbound-channel-adapter 
        id="ftpInbound"
        channel="ftpChannel" 
        filename-pattern="*.csv" 
        session-factory="ftpClientFactory"
        auto-create-local-directory="true" 
        delete-remote-files="true"
        remote-directory="/" 
        local-directory="C:/folder/IN">
            <int:poller fixed-rate="1000" max-messages-per-poll="15"/>
    </int-ftp:inbound-channel-adapter>

</beans>

我在 pom 文件中添加了依赖项，如下所示：

<dependency>
   <groupId>org.springframework.integration</groupId>
   <artifactId>spring-integration-ftp</artifactId>
   <version>2.2.0.RELEASE</version>
</dependency>

实际上 Spring Integration 至少需要 Spring 核心版本 3.0.5，而我将它设置为 3.0.2。一旦我将弹簧核心升级到 3.0.5，它就可以工作了。
