为什么我无法使用selenium和spring连接到服务器？

Question

我无法在ssh下连接到服务器。

我正在使用spring和selenium框架。

如果我使用putty完成这项任务，那一切都还可以。

属性文件：

ssh.url=srv01
ssh.port=22
ssh.username=q1
ssh.password=q1

任何人都可以知道我的问题。

感谢。

main.xml文件，描述了bean

<bean name="ssh" class="com.db.selenium.SSH" init-method="init">
            <property name="remotePlaybackPath" value="${ssh.playback.path}"/>
            <property name="session" ref="sshSession"/>
</bean>

java class

private void init() {
        log.debug("StrictHostKeyChecking = " + JSch.getConfig("StrictHostKeyChecking"));

        try {
            session.connect(); //exception
        } catch (JSchException e) {
            String msg = "Cannot connect to " + session.getUserName() + "@" + session.getHost();
            log.fatal(msg, e);
            throw new RuntimeException(msg, e);
        }

        if (remotePlaybackPath == null || remotePlaybackPath.length() == 0) {
            String msg = "Empty recording path";
            log.fatal(msg);
            throw new RuntimeException(msg);
        } else if (remotePlaybackPath.charAt(remotePlaybackPath.length() - 1) != '/') {
            remotePlaybackPath += '/';
        }
    }
