Spring 集成 DefaultFtpsSessionFactory

Question

在我们将 spring 引导升级到 2.4.2 版本之前，此配置对我来说非常有效。

    DefaultFtpsSessionFactory sessionFactory = new DefaultFtpsSessionFactory();
    sessionFactory.setHost("host");
    sessionFactory.setUsername("username");
    sessionFactory.setPassword("password");
    sessionFactory.setPort(21);
    sessionFactory.setClientMode(FTPClient.PASSIVE_LOCAL_DATA_CONNECTION_MODE);
    sessionFactory.setControlEncoding("UTF-8");

目前我面临以下异常：

javax.net.ssl.SSLException: Unsupported or unrecognized SSL message

我在文档中找不到任何内容。

感谢您的回答。

以下设置工作正常

Answer 1

请考虑使用 commons-net:commons-net:3.7.2 依赖项。

我们确实将 Spring 版本 5.4 的集成从旧的 3.6 升级到 commons-net 3.7。

查看此问题了解更多详情：https://github.com/spring-projects/spring-integration/issues/3463。

我们计划下周发布 5.4.4：https://calendar.spring.io/

Answer 2

将 spring-integration-ftp 降级到 5.3 版本后。2.RELEASE 它可以工作。

<dependency>
  <groupId>org.springframework.integration</groupId>
  <artifactId>spring-integration-ftp</artifactId>
  <version>5.3.2.RELEASE</version>
</dependency>
