Mac os开发环境备忘

1.查找JDK安装路径

打开终端，输入/usr/libexec/java_home -v 1.8 其中1.8为JDK版本号

localhost:~ mac$ /usr/libexec/java_home -v 1.8
/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home

2.启动visualVM

切换到JDK所在目录的bin目录下，运行./jvisualvm，其他包含的可用命令如下： 

appletviewer jarsigner javafxpackager jcmd  jhat  jmc  jstack  keytool  policytool schemagen unpack200
    extcheck java  javah  jconsole jinfo  jps  jstat  native2ascii rmic  serialver wsgen
