    “字节”再次起跳!内部651页剖析HotSpot 源码手册,GitHub开源

    阿嘴记得2年前开始研究Java虚拟机时,查遍了网上所有的资料,凡是能遇到一点好的关于Java虚拟机的资料,我都会认真读、一遍读不懂没关系,阿嘴都会搬到自己的日志中记录下来,后面就是对这些日志进行分类整理,然后加上我的理解后不断加工,最后内化成自己的东西。现在市面上系统介绍Java虚拟机的书籍非常少,细致全面的书籍更是市场空白,所以我把我这几年的所学写成了这本“深入剖析Java虚拟机源码剖析与实例详解(基础卷)”,本书以通俗易懂的语言详细介绍Java虚拟机HotSpot的源码实现,可以帮助读者系统掌握类的生命周期和垃圾回收等基本组件的相关知识。对于想全面了解HotSpot虚拟机工作原理和源码实现的广大Java程序员来说,本书可谓雪中送炭,值得细读。

    解决MySQL连接问题:Access Denied和SSL警告;MySQL数据库连接失败:Access Denied异常的解决方法;如何在Java应用程序中正确配置MySQL数据库连接

    报错“Connected to the target VM, address: '127.0.0.1:59549', transport: 'socket' Wed Sep 13 16:56:02 CST 2023 WARN: Establishing SSL connection without server's identity verification is not recommended.
