OpenJDK17一些JVM参数变化
由于租用的服务器内存比较小，所以配置了一下网站的JVM参数看下有没有什么优化空间。但是配置后发现启动不了，首先提示下面错误：```UnrecognizedVMoption'PrintGCDateStamps'Error:CouldnotcreatetheJavaVirtualMachine.Error:Afatalexceptionhasoccurred.Programwillexit.```这个是由于`PrintGCDateStamps`配置已经废弃了，所以改为`-Xlog:gc::utctime`。然后还有配置日志的参数也改了：```-Xloggcisdeprecated.Willuse-Xlog:gc:./logs/gc.loginstead.Unrecognizedoption:-JARError:CouldnotcreatetheJavaVirtualMachine.Error:Afatalexceptionhasoccurred.Programwillexit.```这个就比较人性化了，直接提示该使用那个参数替换。还有很多参数都被废弃了：```[0.002s][warning][gc]-XX:+P...

##05月16号星期一天气阴最近广州每天都在下雨，都已经五月中旬了，天气还是非常凉爽的，甚至有一点点微冷。公司现在`996`，确实有点累，以前从来没有加过班。我时常在想，除了上有老，其他的我什么都没有，这么拼干什么。其实每个月有个万把块钱的工资，就已经可以让我过的舒舒服服了，何必呢？回到老家开个小面管，每天蓝天白云、绿水青山、清风明月，悠闲的过着日子不是更加舒适。但是仔细想想，每天上班的生活已经把我调教成了过不了清闲日子的人了，也许真的闲下来只会让我更加心慌吧。不管怎么样到了四十岁，快的话三十五岁我就想过点慢节奏的生活了。生活太快，都来不及体验，挺累的。
