Java uses SPIRNG to monitor CPU usage status ....

First of all.. Using SIGAR, SIGAR use to be aware of whether the distinction is web or local. It is best to copy the DLL file under Web-inf. Because Web-inf will not be compressed ...

 Try {            //If you are running Web-mode: Webapplicationcontext Web =Contextloader.getcurrentwebapplicationcontext (); ServletContext Context=Web.getservletcontext (); LibPath= Context.getrealpath ("Web-inf/c_lib"); } Catch(Noclassdeffounderror err) {//non-web mode//err.printstacktrace ();            Try{LibPath= Urldecoder.decode (sigarutil.class. getClassLoader (). GetResource ("Clib"). GetFile (), "Utf-8"); } Catch(Unsupportedencodingexception ex) {ex.printstacktrace (); }        } Catch(Exception e) {Throw NewRuntimeException ("Exception occurred:" + e.getcause () + ", Reason:" +e.getmessage ()); }

Use @cacheput () to put information into the cache .....

Use @Scheduled execute every second: Put to cache ...

Note: @CachePut method cannot be placed under a class with @Scheduled ... Anyway, I put together a mistake .... The reason is unknown .....
