javaandjvisualvmwith an environment variableTMP=E:\temp.-----------------设置TMP环境变量
下面有三种方法设置环境变量
There are three options to set the environment variable for java:
- In your IDE, go to the project options or launch options and find the ‘Environment‘ entry, then enter
TMP=E:\temp - Open a
cmdprompt, and executeset TMP=E:\tempbefore launching youur java application from the same prompt. - Put the two lines you‘d enter at the cmd prompt in a
.batfile. Optinally addpauseat the end of the bat file to prevent the console window from disappearing in case of a runtime exception or vm crash.
Similarly, for JVisualVM, use one of the last two options.
再点击软件，右键设置以管理者模式打开，ok~
