JDK7 +中的OperatingSystemMXBean getProcessCpuTime（） [英] OperatingSystemMXBean getProcessCpuTime() in JDK7+

问题描述

我看到jdk6的代码具有以下OperatingSystemMXBean方法：

  OperatingSystemMXBean osbean = 
（OperatingSystemMXBean）ManagementFactory .getOperatingSystemMXBean（）; 
 
 long prevProcessCpuTime = osbean.getProcessCpuTime（）; 
  

在JDK7文档中似乎没有提及它们。

在jdk7 +的其他地方是否有jdk6方法的等价物？

解决方案

您在API文档中查找错误的位置，它位于7

https://docs.oracle.com/javase/7/docs/jre/ api / management / extension / com / sun / management / OperatingSystemMXBean.html＃getProcessCpuTime％28％29

I see code for jdk6 that has the following OperatingSystemMXBean method :

OperatingSystemMXBean osbean = 
    (OperatingSystemMXBean)      ManagementFactory.getOperatingSystemMXBean();

long prevProcessCpuTime = osbean.getProcessCpuTime();

In the JDK7 docs there appears not to be any mention of them. http://docs.oracle.com/javase/7/docs/api/java/lang/management/OperatingSystemMXBean.html

Are there any equivalents to the jdk6 method elsewhere in the jdk7+ ?

解决方案

You are looking at wrong place in API doc, It is there in 7

https://docs.oracle.com/javase/7/docs/jre/api/management/extension/com/sun/management/OperatingSystemMXBean.html#getProcessCpuTime%28%29
