java - 如何从字符串的动态列表中替换特定单词

Question

如何从包含“ {ts '2017-01-12 16:09:20'} ”的字符串列表中替换“当前时间戳” ，每个字符串的ts值都发生了变化。

eg: //需要将旧时间戳值列表替换为当前时间戳

private void replaceOldTimeStampToCurrentTimeStamp(){
    List<String>sampleString = new ArrayList<String>();
    sampleString.add("VALUES ('CODE','01234','DDC','DDC','',1,'01100',null,null,'Y','SD','PRODUCT','','','',2200,2603,{ts '2017-04-25 14:09:20'},'dba',{ts '2017-04-25 14:09:20'},'dba')");
    sampleString.add("VALUES ('TYPE','NW','New','New','',1,'01100',null,null,'Y','PRODUCT',null,'','',2200,2604,{ts '2017-01-12 16:09:20'},'dba',{ts '2017-01-12 16:09:20'},'dba')");
}

所需的输出：

VALUES('TYPE','NW','New','New','',1,'01100',null,null,'Y','PRODUCT',null,'','',2200,2604 ,当前时间戳,'dba',当前时间戳,'dba')

VALUES('CODE','01234','DDC','DDC','',1,'01100',null,null,'Y','SD','PRODUCT','','',' ',2200,2603,当前时间戳,'dba',当前时间戳,'dba')

你可以尝试这样的事情：

private void replaceOldTimeStampToCurrentTimeStamp(){
    String ts = "current timestamp" //the value you want, a string value
    List<String>sampleString = new ArrayList<String>();
    sampleString.add("VALUES ('CODE','01234','DDC','DDC','',1,'01100',null,null,'Y','SD','PRODUCT','','','',2200,2603,"+ts+",'dba',"+ts+",'dba')");
    sampleString.add("VALUES ('TYPE','NW','New','New','',1,'01100',null,null,'Y','PRODUCT',null,'','',2200,2604,"+ts+",'dba',"+ts+",'dba')");
}
