之前換電腦後安裝jmeter，啟動後有如下報錯，度娘了好多地方，最後終於解決，現將解決方法記錄如下：

解決辦法：
通過echo %PATH% 檢視環境變數
C:\ProgramData\Oracle\Java\javapath;"%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin";
Notice the literal value %JAVA_HOME%\bin. This is caused by:
'PATH' contains reference of other variable
'PATH' is modified without evaluation (e.g. by program)
Solution
Open the environment setting box
Do some modification of the value of PATH (trigger the expansion of variables)（修改環境變數，path中直接設定JAVA的絕對路徑，如C:\Program Files\Java\jre1.8.0_73\bin）
再次檢視環境變數設定
就能識別JAVA的絕對路徑C:\Program Files\Java\jre1.8.0_73\bin;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Common Files\NetSarang
