The #* #的形式作为占位符 is used here to identify the place to be processed.

Use regular processing code:

String content = "#applyCom # has requested settles confirmation for the" #applyType # "item with the number" #applyNo # ". Please log in to the system in time to view processing.   ";  Assemble the data that needs to be replaced, replace the placeholder hashmap<string with the values inside the map, string> map = new hashmap<string, string> ();  Map.put ("applycom", "a");  Map.put ("Applytype", "B");  Map.put ("Applyno", "C");  Pattern Pat = Pattern.compile ("(#[^#]*#)");//define regular Matcher mat = pat.matcher (content);  int i = 0; while (Mat.find ()) {//If there is a match String temp = mat.group (1). ToString (). substring (1, mat.group (1). ToString (). Length ()-1);//  Get placeholders, such as: #applyCom # will get applycom content = Content.replace (Mat.group (1), Map.get (temp)),//Get the value from the map, and replace the placeholder i++; } System.out.println (content);//Print final string
