jinfo：Java配置信息工具
功能描述
jinfo（Configuration Info for Java）的作用是实时地查看和调整虚拟机各项参数。 使用jps命令的-v参数 可以查看虚拟机启动时显式指定的参数列表，但如果想知道未被显式指定的参数的系统默认值， 就只能使用jinfo的-flag选项进行查询了 jinfo还可以使用-sysprops选项把虚拟机进程的 System.getProperties（）的内容打印出来。 |
jinfo命令格式
| jinfo [option] pid |
jinfo工具主要选项
| -flag <name> 打印指定name的JVM flag -flag [+|-]<name> 启用或者禁用指定name的JVM flag -flag <name>=<value> 设置指定名称的name flag为给定的值 -flags 打印JVM flags -sysprops 打印Java系统属性 <no option> 不指定任何option，则打印出所有的JVM flags和sysprops -h | -help 打印帮助信息 |
Example
jinfo -flag <name> : 打印指定name的JVM flag
C:\Users\li>jinfo -flag UseConcMarkSweepGC 6160
-XX:+UseConcMarkSweepGCC:\Users\li>jinfo -flag UseG1GC 6160
-XX:-UseG1GCjinfo -flag [+|-] <name>: 启用或者禁用指定name的JVM flag
首先查看进程11712带有的启动参数
C:\Users\li>jps -v
11712 DxhDeliveryWebApplication -XX:+PrintGCDetails -XX:TieredStopAtLevel=1 -Xverify:none -Dspring.output.ansi.enabled=always -javaagent:D:\software\IntelliJ IDEA 2017.1.5\lib\idea_rt.jar=56375:D:\software\IntelliJ IDEA 2017.1.5\bin -Dfile.encoding=UTF-8将PrintGCDetails 打印GC信息去掉，什么都不返回代表已经成功去掉了
jinfo -flag -PrintGCDetails 11712之后查看已经没有了 ，再次添加后又有了
C:\Users\li>jinfo -flag PrintGCDetails 11712
-XX:-PrintGCDetails
C:\Users\li>jinfo -flag +PrintGCDetails 11712
C:\Users\li>jinfo -flag PrintGCDetails 11712
-XX:+PrintGCDetails注意：
1、如果运行过程中，通过jinfo修改了，则修改后的值只能通过jinfo看到，jps是看不到的，jps命令只能看到启动时的jvm参数。
2、很多运行参数是不能调整的，如果出现这种异常，说明不能调整：
C:\Users\li> jinfo -flag SurvivorRatio=7 11712
Exception in thread "main" com.sun.tools.attach.AttachOperationFailedException: flag 'SurvivorRatio' cannot be changed
at sun.tools.attach.WindowsVirtualMachine.execute(WindowsVirtualMachine.java:117)
at sun.tools.attach.HotSpotVirtualMachine.executeCommand(HotSpotVirtualMachine.java:261)
at sun.tools.attach.HotSpotVirtualMachine.setFlag(HotSpotVirtualMachine.java:234)
at sun.tools.jinfo.JInfo.flag(JInfo.java:134)
at sun.tools.jinfo.JInfo.main(JInfo.java:81)-flag <name>=<value>: 设置指定名称的name flag为给定的值
设置指定名称的name flag为给定的值，类似上述异常的操作方式
jinfo -sysprops : 打印java系统属性
C:\Users\li>jinfo -sysprops 11712
