totalString=totalString.replaceAll(newurl,fileName);
bw.write(totalString);

bw.close();
br.close();

我想从Oralce数据库中取出url 如:http://sss/SjLeaveWord.do?sjid=1&tempNum=1作为值传入,用fileName如:index.html去替换,
怎么不能替换呢

Answer 1

如果totalString=totalString.replaceAll(newurl,fileName);
中的newurl写死了totalString=totalString.replaceAll("http://sss/SjLeaveWord.do?sjid=1&tempNum=1","index.html");
这样就能完成功能
