AOP

准备

spring-boot项目

• 依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

war项目

• 依赖

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>5.1.5.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.7.3</version>
</dependency>

• application.xml

<beans xmlns:aop="http://www.springframework.org/schema/aop"
	   xsi:schemaLocation="
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
    
    <!--开启aop-->
	<aop:aspectj-autoproxy />

</beans>

使用

• 通过注解

@Aspect
public class MyAop{

    @Pointcut("execution(* com.wl.sb.controller.FirstController.*(..))")
    public void myPointCut(){}
    
    @Around("myPointCut()")
    public Object handlerControllerMethod(ProceedingJoinPoint pjp){
        //执行当前切入点方法
        pjp.proceed();
        //获取当前切入点带包路径
        pjp.getSignature();
    }
}

• 通过配置的方式

<bean id="controllerAop" class="com.wl.aop.ControllerAop" />
<aop:config>
    <aop:aspect id="myAop" ref="controllerAop">
        <aop:pointcut id="target"
                      expression="execution(* com.wl.controller.FirstController.*(..))" />
        <aop:around method="handlerControllerMethod" pointcut-ref="target" />
    </aop:aspect>
</aop:config>
