【sping揭秘】15、afterreturning

@afterreturning

我们同理写几个测试类

package cn.cutter.start.bean;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Component;

@Component
public class AterReturningTestBean {

    private static final Log logger = LogFactory.getLog(AterReturningTestBean.class);

    public void aterReturningTest() {
        logger.info("aterReturningTest sds");
    }

    public int aterReturningTestInt() {
        logger.info("aterReturningTestInt");

        return 666;
    }

}

写几个测试的拦截器

package cn.cutter.start.aop;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;

/**
 *
 * @author xiaof
 *
 */
@Component
@Aspect
public class AterReturningAspect {

    private static final Log logger = LogFactory.getLog(AterReturningAspect.class);

    //execution(* cn.cutter.start.bean.BeofreTestBean.*(..))
    @Pointcut("execution(* cn.cutter.start.bean.AterReturningTestBean.*(..))")
    private void pointCut1() {}

    @AfterReturning(pointcut="pointCut1()", returning="value1")
    public void testReturn1(int value1) {

        logger.info("返回拦截：" + value1);

    }

    @AfterReturning(pointcut="pointCut1()")
    public void testReturn2() {

        logger.info("返回拦截：没有参数");

    }

}

结果：

@Test
    public void testAop4() {
        ApplicationContext ctx = this.before();

        AterReturningTestBean att = (AterReturningTestBean) ctx.getBean("aterReturningTestBean");

//        att.aterReturningTest();

        att.aterReturningTestInt();

    }
