Java读文件修改默认换行符的实现

public static void testRead(String confPath) throws IOException {
 System.setProperty("line.separator", "/03");
 BufferedReader brConf = new BufferedReader(new InputStreamReader(
   new FileInputStream(confPath), "UTF-8"));
 for (String line = brConf.readLine(); line != null; line = brConf.readLine()) {
  System.out.println(line);
  System.out.println("----------------");
 }
 brConf.close();
}

String testStr = "换行rn换行";
String result = testStr.replaceAll("(\r\n|\n|\n\r)","<br/>");
