尝试连接SFTP主机时出现以下异常。我添加了stacktrace和我的配置文件设置以及我用于sftp的依赖项。

Answer 1

这可能是因为您错过了spring-integration-sftp.jar中的classpath文件。您可以验证此文件是否在classpath中。如果没有，请在下面添加一个：

<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-sftp</artifactId>
    <version>4.1.5.RELEASE</version>
</dependency>

无法找到XML架构命名空间的Spring NamespaceHandler [http://www.springframework.org/schema/integration/sftp]
