1. 在线激活

  安装IntelliJ IDEA版本后,永久激活可参考https://blog.51cto.com/825272560/2350356,亲测有效(@2020.02.22)

 

 

1. 优化JVM参数

  修改 IntelliJ IDEA 2016.1.2/bin/idea.exe.vmoptions【记得备份】文件,如果是x64系统,修改idea64.exe.vmoptions文件中的参数,具体参数如下:

-Xms512m
-Xmx750m
-Xmn264m
-XX:MaxPermSize=350m
-XX:PermSize=128m
-XX:ReservedCodeCacheSize=240m
-Xverify:none
-Xnoclassgc
-XX:+UseParNewGC
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-server
-Dsun.io.useCanonCaches=false
-Dsun.awt.keepWorkingSetOnMinimize=true
-Djava.net.preferIPv4Stack=true
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow

  注:-Xms512m 设置初时的内存大小,提高Java程序的启动速度

    -Xmx750m 设置最大内存数,提高该值,可以减少内存Garage收集的频率,提高程序性能

    -Xverify:none 关闭Java字节码验证,从而加快了类装入的速度,并使得在仅为验证目的而启动的过程中无需装入类,缩短了启动时间

    -XX:+UseParNewGC 使用并行收集算法

    -server 控制内存garage方式,这样你无需在花一到两分钟等待内存garage的收集

    -Dsun.awt.keepWorkingSetOnMinimize=true 可以让IDEA最小化到任务栏时依然保持以占有的内存,当你重新回到IDEA,能够被快速显示,而不是由灰白的界面逐渐显现整个界面,加快回复到原界面的速度。

2.  基本常用设置
