AspectJ的兩種實現

① 基於xml方式實現：

public

class
myaspect
public
void
myafterretruning
(joinpoint joinpoint)
}

public

inte***ce
userservice

1. 建立實體類 --

>
"userserviceid"
class
="com.itt.c_aspectj_xml.userserviceimpl"
>
<
/bean>
2. 建立切面類--
>
"aspectid"
class
="com.itt.c_aspectj_xml.myaspect"
>
<
/bean>
3. 建立**類--
>
將切面類宣告「切面」， 獲得通知
切入點，expression:為切入點表示式
"" pointcut-ref=
"">
前置通知，method為通知的方法，pointcut-ref為切入點的引用
-->
"aspectid"
>
"myaspectid" expression=
"execution(* com.itt.c_aspectj_xml.userserviceimpl.*(..))"
/>
"mybefore" pointcut-ref=
"myaspectid"
>
<
/aop:before>
"myafterretruning" pointcut-ref=
"myaspectid"
>
<
/aop:after>
<
/aop:aspect>
<
/aop:config>

②基於註解方式:

//切面類

@component
@aspect
public
class
myaspect
@before
(value =
"mypoint()"
)public
void
mybefore
(joinpoint joinpoint)
@after
(value =
"mypoint()"
)public
void
myafterretruning
(joinpoint joinpoint)
}

@service

("userserviceid"
)//指定生成的bean的id
public
class
userserviceimpl
implements
userservice
@override
public string updateuser()
@override
public
void
deleteuser()
}

<

!--掃瞄所有的註解--
>
package
="com.itt.c_aspectj_xml"
>
<
/context:component-scan>
<
!--確定aop註解生效--
>
<
/aop:aspectj-autoproxy>
