无论什么级别的Java从业者,JVM都是进阶时必须迈过的坎。不管是工作还是面试中,JVM都是必考题。如果不懂JVM的话,薪酬会非常吃亏(近70%的面试者挂在JVM上了)。 | ||

掌握了JVM机制,就等于学会了深层次解决问题的方法。对于Java开发者而言,只有熟悉底层虚拟机的运行机制,才能通过JVM日志深入到字节码的层次去分析排查问题,发现隐性的系统缺陷,进而提升系统性能。 | ||

一些技术人员开发工具用得很熟练,触及JVM问题时却是模棱两可,甚至连内存模型和内存区域,HotSpot和JVM规范,都混淆不清。工作很长时间,在生产时还在用缺省参数来直接启动,以致系统运行时出现性能、稳定性等问题时束手无措,不知该如何追踪排查。久而久之,这对自己的职业成长是极为不利的。 | ||
