java - 多个不区分大小写的字符串替换

Question

我想从一个字符串中替换多个不区分大小写的字符串。

我本可以使用: org.apache.commons.lang.StringUtils.replaceEach(text, searchList, replacementList)

但适用于区分大小写的字符串。

是否有类似的方法适用于不区分大小写的字符串？

static String[] old = {"ABHISHEK","Name"};
static String[] nw = {"Abhi","nick name"};
static String s="My name is Abhishek";
System.out.println(StringUtils.replaceEach(s, old, nw));

输出:

My name is Abhishek

预期:

My nick name is Abhi

你可以尝试使用regex存档

例子

String str = "Dang DANG dAng dang";
//replace all dang(ignore case) with Abhiskek
String result = str.replaceAll("(?i)dang", "Abhiskek");
System.out.println("After replacement:" + "   " + result);

结果:

After replacement: Abhiskek Abhiskek Abhiskek Abhiskek

String[] old = {"ABHISHEK","Name"};
String[] nw = {"Abhi","nick name"};
String s="My name is Abhishek";
//make sure old and nw have same size please
for(int i =0; i < old.length; i++) {
    s = s.replaceAll("(?i)"+old[i], nw[i]);
}
System.out.println(s);

结果:

My nick name is Abhi

基本理想:Regex ignore case和 replaceAll()

来自评论@flown(谢谢)你需要使用

str.replaceAll("(?i)" + Pattern.quote(old[i]), nw[i]);

因为正则表达式将一些具有不同含义的特殊字符，例如:. 视为任何单个字符

所以使用 Pattern.quote 就可以做到这一点。
