尝试使用 jsch 和 jdbc 连接到 postgres 数据库会产生 "The connection attempt failed. Caused by: java.io.EOFException"
Trying to connect to postgres database with jsch and jdbc yields "The connection attempt failed. Caused by: java.io.EOFException"
我正在尝试连接到 Amazon EC2 服务器上的 postgres 数据库 运行。我知道服务器配置正确，因为我可以从 pgadmin 访问它并作为 intellij 中的数据源。
我也可以在仅使用 jsch 时从我的程序中连接到服务器 shell，并使用 jdbc 直接连接到另一个数据库，但是一旦我尝试通过 ssh 连接到我的 postgres 实例使用 jsch 隧道我遇到了一个我无法诊断的奇怪错误。:

我用来连接的代码如下：
System.out.println("Connecting...");
session = secConnect.getSesssion();
UserInfo ui = new uInfo();
session.setUserInfo(ui);
session.connect();
session.setPortForwardingL(5432,secConnect.getHost(),5432);
System.out.println("SSH Tunneled");
System.out.println("Opening Database Connection");
Class.forName("org.postgresql.Driver");
Properties props = new Properties();
props.setProperty("user","username");
props.setProperty("password","password");
props.setProperty("loglevel", "2");
connection = DriverManager.getConnection("jdbc:postgresql://localhost:5432/dbname",props);
System.out.println("Connected");
secConnect对象的相关代码在这里：
jsch.addIdentity(chooser.getSelectedFile().getAbsolutePath());
public Session getSesssion() throws JSchException {
return jsch.getSession(user, host, 22);
}
我的 ec2 postgres 服务器配置为 listenaddress = '*' 并且 pg_hba.conf 有行
host all all 0.0.0.0/0 md5
