问题描述

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();
                }
            }
        }
    }
}
