Java正規表現式でSQLコード、改行、余計スペースを除去
処理コード1:
public static void main(String[] args) {
String sql = “SELECT * FROM \n" +
" `testdb`.`foo` LIMIT 0, 100″;
String s = “SELECT * FROM `testdb`.`foo` LIMIT 0, 100";
String sql2 = Pattern.compile(" {2,}").matcher(s).replaceAll(" “);
String sql3 = s.replaceAll(" {2,}"," “);
String sql4 = sql.replace('\r’, ' ').replace('\n’, ' ').replaceAll(" {2,}"," “);;
String sql5 = sql.replace('\r’, ' ').replace('\n’, ' ').replaceAll(" {2,}?"," “);;
String sql6 = sql.replace('\r’, ' ').replace('\n’, ' ').replaceAll(" {2,}+"," “);;
System.out.println(sql2);
System.out.println(sql3);
System.out.println(sql4);
System.out.println(sql5);
System.out.println(sql6);
}
処理コード2:
public boolean isAlreadySegmentSQL(String sql) {
return sql.replace('\r’, ' ').replace('\n’, ' ').replaceAll(" {2,}", " “).matches(“(?i).+LIMIT [\\d+ *|\\d *, *\\d+].+");
}
処理コード3:
// regList.put(“(?i)bit\\([2-9]\\)\\z", “byte[]");
// regList.put(“(?i)bit\\(\\d{2,}\\)\\z", “byte[]");
regList.put(“(?i)bit\\((\\d{2,}|[2-9])\\)\\z", “byte[]");
