Snowflake JDBC 如何檢查主機名/服務器的有效性？
[英]Snowflake JDBC How to check hostname / server validity?
問題描述
我正在測試我的 Snowflake JDBC 連接，但遇到了一個問題：如何處理無效的 Snowflake 主機名稱？
例如正確的主機名應該是 123abc.us-east-1 但我輸入 123123.us-east-1
這是代碼：
public static Connection getConnection(connectConfigs sfconfig) {
try {
Class.forName("com.snowflake.client.jdbc.SnowflakeDriver");
} catch (ClassNotFoundException ex) {
System.err.println("Driver not found");
}
try {
// build connection properties
Properties properties = new Properties();
properties.put("user", sfconfig.getSfUser()); // replace "" with your username
properties.put("password", sfconfig.getSfPassword()); // replace "" with your password
properties.put("account", sfconfig.getSfURL()); // replace "" with your account name
properties.put("db", sfconfig.getSfDatabase().toUpperCase()); // replace "" with target database name
properties.put("schema", sfconfig.getSfSchema().toUpperCase()); // replace "" with target schema name
properties.put("loginTimeout", 30);
//properties.put("tracing", "on");
// create a new connection
String connectStr = System.getenv("SF_JDBC_CONNECT_STRING");
// use the default connection string if it is not set in environment
if (connectStr == null) {
connectStr = "jdbc:snowflake://" + sfconfig.getSfURL() + ".snowflakecomputing.com"; // replace accountName with your account name
}
return DriverManager.getConnection(connectStr, properties);
} catch (SQLException e) {
System.err.println("some error here");
}
return null;
}
如果我提供了無效的主機名，所有這些都會打印到控制台：

<body>
<center><h1>403 Forbidden</h1></center>
</body>
</html>
我怎樣才能優雅地處理這個而不是把這個巨大的混亂打印到控制台？
提前謝謝！

將這一行添加到連接屬性解決了我的問題。
properties.put("tracing", "OFF");
