我正在尝试使用Spring Integration(版本2.2.0.RELEASE)设置我的应用程序以接收文件。 当我启动Tomcat(部署应用程序)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红鲱鱼。在将spring集成依赖项添加到pom文件并使用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:

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>
答案 0 :(得分:2)
实际上,Spring Integration至少需要Spring核心版本3.0.5,而我将其设置为3.0.2。一旦我将spring core升级到3.0.5,就可以了。
