### 1、目标类 ###

package com.aop;
    
    
    import org.springframework.stereotype.Component;
    
    // 代理目标类
    @Component
    public class BusinessService {
        public void executeBuss() {
            System.out.println("执行业务处理...");
        }
    }

### 2、Aop切面与切点配置类 ###

package com.aop;
    
    import org.aspectj.lang.ProceedingJoinPoint;
    import org.aspectj.lang.annotation.Around;
    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.annotation.Pointcut;
    import org.springframework.stereotype.Component;
    
    /**
     * 切面配置
     */
    @Component
    @Aspect
    public class AspectConfig {
    
        @Pointcut("execution(* com.aop..*(..))")
        private void pointCut() {
        }
    
        /**
         * 环绕通知
         */
        @Around("pointCut()")
        public Object testAround(ProceedingJoinPoint joinPoint) throws Throwable {
            System.out.println("切面_执行业务前打印日志...");
            Object obj = joinPoint.proceed();
            System.out.println("切面_执行业务后打印日志...");
            return obj;
        }
    }

### 3、bean配置config类 ###

package com.aop;
    
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    @ComponentScan(basePackages = "com.aop")
    public class BeansConfig {
    
    }

### 4、测试类\_main方法 ###

package com.aop;
    
    import org.springframework.context.annotation.AnnotationConfigApplicationContext;
    
    
    public class ZAopMainTest {
    
        public static void main(String[] args) {
            // 通过Java配置来实例化Spring容器
            AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(BeansConfig.class);
    
            // 在Spring容器中获取Bean对象
            BusinessService businessService = context.getBean(BusinessService.class);
            businessService.executeBuss();
    
    
            // 销毁该容器
            context.destroy();
        }
    }

### 5、打印结果 ###

> 切面\_执行业务前打印日志...  
> 执行业务处理...  
> 切面\_执行业务后打印日志...

### 6、pom文件参考 ###
