title: How can I custom AspectJ aop.xml location?
body: <p>I have the same question related to this:
  <a href="https://stackoverflow.com/questions/3736860/aop-xml-name-and-location">aop.xml name and location?</a></p>
  
  <p>In the answers, it says:</p>
  
  <p>use the system property:
  -D org.aspectj.weaver.loadtime.configuration=META-INF/myaop.xml </p>
  
  <p>What does "use the system property" mean?</p>
  
  <p>create a aop.properties file?
  Or, write in the vm option?</p>
