Spring Things management-declarative (AspectJ) annotation implementations (recommended)

1. Table structure and data

2. Jar Package Used

3. Service, DAO layer interface and implementation class:

DAO Interface:

 //  transfer case persistence layer interface   Public  interface   Accountdao { /*  * * @param out: Transfer account * @param money: Transfer Amount  */ public          void  Outmoney (String out  ,double money);     /*  * * @param in: Transfer account * @param money  : Transfer amount  */ public  void  Inmoney (String in  ,double    Money); }

DAO implementation class:

//Transfer case Persistence layer implementation class Public classAccountdaoimpl extends Jdbcdaosupport implements Accountdao {/** * @param out: Transfer account * @param money: Transfer amount*/@Override Public voidOutmoney (String out, Double Money) {String SQL="Update account Set money = Money-? WHERE name =?";  This. Getjdbctemplate (). Update (Sql,money, out); }    /** * @param in: Transfer account * @param money: Amount Transferred*/@Override Public voidInmoney (Stringinch, Double Money) {String SQL="Update account Set money = Money +? WHERE name =?";  This. Getjdbctemplate (). Update (Sql,money,inch); }}

Service Interface:

// transfer case Business layer interface  Public Interface Accountservice {    /* * *     @param    out: Transfer account     * @param in    : Transfer account     * @param    Money: Transfer amount     */ public     void  -In , Double money);}

Service Implementation class:

Using @transactional things annotations, you can use different annotation attributes depending on your needs propagation, isolation, readOnly, rollbackfor, norollbackfor

//Transfer case Business Layer implementation class@Transactional (propagation=propagation.required)//Using annotations for transaction management, using different annotation attributes as required Public classAccountserviceimpl implements Accountservice {//the DAO injected into the transfer@ResourcePrivateAccountdao Accountdao; /** * @param out: Transfer account * @param in: Transfer account * @param money: Transfer amount*/@Override Public voidTransfer (String out, Stringinch, Double Money) {                //put business operations into internal classes----in one thing (with success, same failure)Accountdao.outmoney ( out, Money); inti =1/0;//Anomaly TestingAccountdao.inmoney (inch, Money); }}

4. applicationcontext.xml File configuration:

5. Test class:

//Spring Declarative Way of managing things two test classes: ASPECTJ-based XML configuration@RunWith (Springjunit4classrunner.class) @ContextConfiguration ("Classpath:applicationContext4.xml") Public classSpringDemo4 {//need to inject business layer proxy objects@Resource (name="Accountservice")    PrivateAccountservice Accountservice; @Test Public voidDemo4 () {Accountservice.transfer ("AAA","BBB", 200d); }}
