javalangClassCastException comhthorizonhtodasmconnectionJschConnection cannot be cast to orgapachecommonspool2PooledObject这是报错代码为 Override public PooledObject wrapObject o SSHConnection ss

出现这个错误是因为sshConnection对象不是PooledObject的实例，所以无法进行强制类型转换。解决这个问题可以通过将sshConnection对象包装成一个DefaultPooledObject对象来解决。下面是一个可能的解决方案示例代码：

@Override
public PooledObject<SSHConnection> wrap(Object o) {
    SSHConnection sshConnection = (SSHConnection) o;
    boolean flag = sshConnection.createConnection();
    if (flag) {
        return new DefaultPooledObject<>(sshConnection);
    } else {
        throw new RuntimeException("create ssh connection failed");
    }
}

这里使用DefaultPooledObject类来包装sshConnection对象，返回一个PooledObject<SSHConnection>对象。这样就可以避免强制类型转换错误
