示例1: refreshTypes
import com.impossibl.postgres.api.jdbc.PGConnection; //导入依赖的package包/类
@SneakyThrows
public static void refreshTypes(Connection connection) {
PGConnection conn = getPgConnection(connection);
PGConnectionImpl connImpl = (PGConnectionImpl) conn;
Version serverVersion = connImpl.getServerVersion();
//Load types
String typeSQL = PgType.INSTANCE.getSQL(serverVersion);
pgTypes = connImpl.queryResults(typeSQL, PgType.Row.class);
//Load attributes
String attrsSQL = PgAttribute.INSTANCE.getSQL(serverVersion);
pgAttrs = connImpl.queryResults(attrsSQL, PgAttribute.Row.class);
//Load procs
String procsSQL = PgProc.INSTANCE.getSQL(serverVersion);
pgProcs = connImpl.queryResults(procsSQL, PgProc.Row.class);
}
示例2: startNotificationListener
import com.impossibl.postgres.api.jdbc.PGConnection; //导入依赖的package包/类
@Override
public void startNotificationListener(DBMSSynchronizer dbmsSynchronizer) {
// Disable cleanup output of ThreadedHousekeeper
Logger.getLogger(ThreadedHousekeeper.class.getName()).setLevel(Level.SEVERE);
this.listener = new PostgresSQLNotificationListener(dbmsSynchronizer);
PGDataSource dataSource = new PGDataSource();
dataSource.setHost(connectionProperties.getHost());
dataSource.setPort(connectionProperties.getPort());

dataSource.setUser(connectionProperties.getUser());
dataSource.setPassword(connectionProperties.getPassword());
try {
pgConnection = (PGConnection) dataSource.getConnection();
pgConnection.createStatement().execute("LISTEN jabrefLiveUpdate");
// Do not use `new PostgresSQLNotificationListener(...)` as the object has to exist continuously!
// Otherwise the listener is going to be deleted by GC.
pgConnection.addNotificationListener(listener);
} catch (SQLException e) {
LOGGER.error("SQL Error: ", e);
}
}
示例3: refreshConnectionRegistry
import com.impossibl.postgres.api.jdbc.PGConnection; //导入依赖的package包/类
