My  Fancy  New  Web  ApplicaCon  

ApplicaCon  Development  &  TesCng  

•  So  your  building  your  fancy  new  web  applicaCon  –  Is  it  working  the  way  you  expected?  – What  caused  that  failure?  – How  is  the  performance?  – Why  is  it  slow?  – What  the  heck  is  Hibernate  (or  whatever)  doing?  

My  Fancy  New  Web  ApplicaCon  

What  do  you  do  when  it  fails?  

•  Check  the  logs?  – Timestamps  – Session  IDs,  User  IDs  – Log  all  the  parameters  –  UGH?  

•  Run  the  debugger?    – Typically  doesn’t  help  with  performance  

•  And  what  do  you  do  in  QA  and  Performance  TesCng?    When  it  fails?    When  it  is  slow?  

There  has  got  to  be  a  beXer  way!  

•  Spring  Insight!

How  does  it  work?  

•  Spring  Insight  uses  automaCc  code  instrumentaCon  to  monitor  your  applicaCon  

•  It  does  this  by  introspecCng  exisCng  annotaCons  and  interfaces  for  key  aspects  of  your  applicaCon  

•  It  then  uses  AspectJ  AOP  point  cuts  to  monitor  the  code    

•  Runs  in  tc  Server  (Tomcat)  beside  your  web  applicaCon

AnnotaCons  

•  If  you  want  to  monitor  more  aspects  of  your  code  you  can  simply  annotate  the  methods  

Dynamic  Concrete  Aspects  <?xml  version="1.0"  encoding="UTF-­‐8"?>  <aspectj>          <aspects>                <concrete-­‐aspect  name="foo.bar.BazAspect”  extends="com.springsource.insight.collecCon.method.custom.CustomConcreCzedOperaConCollecConAspect">                        <pointcut  name="collecConPoint"    

 expression="execu;on(*  foo.bar.Baz.mySuperDuperMethod(..))"  />                </concrete-­‐aspect>          </aspects>  </aspectj>  

Dynamic  Concrete  Aspects  

•  Instrument  classes  and  methods  that  are  not  covered  by  plugins  or  Insight  annotaCons  

•  Defined  in  AspectJ  XML  configuraCon  •  No  changes  to  source  code  required!  

Spring  Insight  •  AutomaCc  •  No  Coding  &  No  ConfiguraCon  

•  Shows  Errors  •  Shows  Performance  •  Pluggable  •  Answers:  “What  Just  Happened?”  

Wrap  Up  

•  Helps  developers,  QA  Testers,  and  in  Stress  and  Performance  tesCng  to  answer:  “What  Just  Happened?”
