【sping揭秘】15、afterreturning

@afterreturning

我們同理寫幾個測試類

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;
    }
    
}

寫幾個測試的攔截器

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("返回攔截：" + value1);
        
    }
    
    @AfterReturning(pointcut="pointCut1()")
    public void testReturn2() {
        
        logger.info("返回攔截：沒有參數");
        
    }
    
}

結果：

@Test
    public void testAop4() {
        ApplicationContext ctx = this.before();
        
        AterReturningTestBean att = (AterReturningTestBean) ctx.getBean("aterReturningTestBean");
        
//        att.aterReturningTest();
        
        att.aterReturningTestInt();
        
    }
