    可以考虑用正则表达式截取你想要的字符串，比如像下面这样：
    String str = "2017-02-05 13:16:25.055 INFO [pool-2-thread-1][AutoTaskServiceImpl.java:152] - [HEART|-1265681417649654475|OUT|2017-02-05 13:16:25][{\"dat";
    Pattern p = Pattern.compile("\[HEART\|-\d*");
    Matcher m = p.matcher(str);
    if (m.find()) {
    System.out.println(m.group(0));
    }
