java - 如何在java中用给定的替换图替换一些单词？

Question

蛋：

String str = "Don't trouble trouble until trouble troubles you"
Map<String,String> replacementMap = new HashMap<String,String>(){{put("trouble","replaceStr");}};

我想要的输出是：

"Don't troubleStr troubleStr until troubleStr troubles you."

场景是我有一个段落，我也有一个关键字数据库，当我在网页中显示该段落时，我想突出显示匹配的关键字并替换链接目标。

  String str = "Don't trouble trouble until trouble troubles you";
    Map<String,String> replacementMap = new HashMap<String, String>(){{put("trouble","replaceStr");}};
    for (Map.Entry<String, String> entry : replacementMap.entrySet()) {
        System.out.println(entry.getKey()); //trouble
        System.out.println(entry.getValue()); // replaceStr
        str = str.replace(entry.getKey(), entry.getValue());
    }
    System.out.println(str);
