Spring-Camel。如何从sftp读取文件（org.apache.camel.ResolveEndpointFailedException：无法解析端点:)

Question

首先我在本地安装了sftp服务器，我可以使用bitwise ssh客户端连接到它：

我的凭据：

登录：tester
密码：password

sftp文件夹如下所示：

我写了以下代码：

 @PostConstruct
    public void init() {
        from("sftp://tester@localhost:22/myFolder?password=password&username=tester")
                .log("msg: ${body}")
                .process(exchange -> {
                    System.out.println(exchange.getIn().getBody());
                });
    }

但是当我尝试启动应用程序时，我会在日志中看到：

我错了什么？

P.S。 我正在阅读this doc

此外，我试图拨打防火墙 - 没有帮助

Answer 1

在我添加

之后它正在工作

compile group: 'org.apache.camel', name: 'camel-ftp-starter', version: '2.20.0'

到build.gradle文件

Answer 2

日志中的错误消息指向rootcause：缺少（s）ftp-component的jar文件。
你需要将camel-ftp-2.20.jar（对于ftp-stuff）和jsch-0.1.54.jar（对于ssh-stuff）添加到类路径中 - 或者让一些构建工具为你做。

Answer 3

在将依赖项添加到项目中后，它起作用了

compile group: 'org.apache.camel', name: 'camel-ftp', version: camelVersion
