java - 在java代码中模板化多行字符串的简单方法

Question

我经常遇到以下情况:我有很长的多行字符串，必须在其中注入(inject)属性 - 例如像模板之类的东西。但我不想在我的项目中包含完整的模板引擎(例如velocity 或freemarker)。

如何以简单的方式完成此操作:

String title = "Princess";
String name  = "Luna";
String community = "Stackoverflow";

String text =
   "Dear " + title + " " + name + "!\n" +  
   "This is a question to " + community + "-Community\n" + 
   "for simple approach how to code with Java multiline Strings?\n" + 
   "Like this one.\n" + 
   "But it must be simple approach without using of Template-Engine-Frameworks!\n" + 
   "\n" + 
   "Thx for ...";

使用 Java 15+:

String title = "Princess";
String name = "Luna";
String community = "Stackoverflow";

String text = """
        Dear %s %s!
        This is a question to %s-Community
        for simple approach how to code with Java multiline Strings?
        """.formatted(title, name, community);
