Development tools: IntelliJ idea 15.0.4, MySQL development language: Java-Web main functions: Compound interest calculation, simple interest calculation because the computational framework has not come and made, So the function can only be implemented in the form of simple interface.  3, Division: Cai Sun: Design of the overall framework, code writing Wang Xinming: access to relevant information, collaborative inspection code

The use of Hibernate framework to achieve Data Link summary: Due to time problems, write the test class, the specific page is not ready.    the next pair will implement specific functions.

Test the asset of the user name (surname Zhang)

@Test Public voidTestcatipal () {Session session=NULL; Try {            //Get SessionSession =hibernatefactory.opensession (); List<User> users = Session.createquery ("Select User from user user left join User.assets asset where user.name like '% sheet% '"). Setfirstresult (0). Setmaxresults ( the). List ();  for(User user:users) { for(Asset asset:user.getAssets ()) {System. out. println (User.getname () +" "+ Asset.getcatipal () +" "+ asset.gettype () +" "+asset.getnowdate ()); }            }        }Catch(Exception e) {e.printstacktrace (); //Business Rollback            if(Session! =NULL) session.gettransaction (). rollback (); }finally {            //End of BusinessHibernatefactory.close (session); }    }

Test adding users and assets
