1 业务核心类

编写业务核心类代码：

public class Calculator {
    public int add(int i, int j) {
        System.out.println("add...");
        return i + j;
    }
}

加入到IOC容器：

<bean id="calculator" class="com.service.Calculator" />

2 切面类

编写切面类代码：

public class AspectWork {
    public void workBefore() {
        System.out.println("WorkBefore...");
    }
    public void workAfter() {
        System.out.println("WorkAfter...");
    }
    public void workAfterReturning(Object result) {
        System.out.println("WorkAfterReturning...");
    }
    public void workAfterThrowing(Throwable exception) {
        System.out.println("WorkAfterThrowing...");
    }
    public Object workAround(ProceedingJoinPoint joinPoint) {
        Object result = null;
        try {
            System.out.println("workAround...WorkBefore...");
            result = joinPoint.proceed(joinPoint.getArgs());
            System.out.println("workAround...WorkAfterReturning...");
        } catch (Throwable e) {
            System.out.println("workAround...WorkAfterThrowing...");
            throw new RuntimeException();
        } finally {
            System.out.println("workAround...WorkAfter...");
        }
        return result;
    }
}

加入到IOC容器：

<bean id="aspectWork" class="com.aspect.AspectWork" />

3 通知方法

配置切入点表达式和通知方法：

<aop:config>
    <!-- 配置切入点表达式。 -->
    <aop:pointcut expression="execution(* *.*(..))" id="pointcut" />
    <!-- 配置切面类和优先级。 -->
    <aop:aspect ref="aspectWork" order="12">
        <!-- 配置切面通知方法。 -->
        <aop:before method="workBefore" pointcut-ref="pointcut" />
        <aop:after method="workAfter" pointcut-ref="pointcut" />
        <aop:after-returning method="workAfterReturning" returning="result" pointcut-ref="pointcut" />
        <aop:after-throwing method="workAfterThrowing" throwing="exception" pointcut-ref="pointcut" />
        <!--<aop:around method="workAround" pointcut-ref="pointcut" />-->
    </aop:aspect>
</aop:config>

4 测试类

编写测试类代码：

public class AspectTest {
    ApplicationContext ioc = new ClassPathXmlApplicationContext("application.xml");
    @Test
    public void test() {
        Calculator calculator = ioc.getBean(Calculator.class);
        calculator.add(1, 3);
    }
}
