您可以查看以下内容：
public static void printSQLException(SQLException ex) { for (Throwable e : ex) { if (e instanceof SQLException) { if (ignoreSQLException( ((SQLException)e). getSQLState()) == false) { e.printStackTrace(System.err); System.err.println("SQLState: " + ((SQLException)e).getSQLState()); System.err.println("Error Code: " + ((SQLException)e).getErrorCode()); System.err.println("Message: " + e.getMessage()); Throwable t = ex.getCause(); while(t != null) { System.out.println("Cause: " + t); t = t.getCause(); } } } }}
