SpringBoot2 引入 Aop

一步小心就掉进坑里面了：SpringBoot2 引入 Aop 不生效

SpringBoot2.1.3版本

首先，引入依赖

    <!--面向切面-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

　　

配置切面

package com.ddkt365.poster.aspect;

import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.stereotype.Component;

/**
 * 切面类记录请求响应日志
 *
 * @author szliugx@gmail.com
 * @create 2019-05-15 上午00:02
 **/

@Aspect
@Component
@Slf4j
public class ApiLogAspect {

    @Pointcut("execution(public * com.ddkt365.poster.web.controllers..*.*(..))")
    public void log() {
        log.info("before cut1, do something");
    }

    @Before("log()")
    public void doBefore(JoinPoint joinPoint) {
        log.info("before cut2, do something");
    }

    @After("log()")
    public void doAfter() {
        log.info("before cut3, do something");
    }

    @AfterReturning(returning = "object", pointcut = "log()")
    public void doAfterReturning(Object object) {
        log.info("before cut4, do something");
        this.printOptLog();
    }

    /**
     * 打印日志方法
     */
    private void printOptLog() {
        log.info("before cut5, do something");
    }
}

就是这么简单的配置，居然翻车了

因为生效的方法必须为 public 申明，刚好测试的控制器（com.ddkt365.poster.web.controllers包下）里的方法省略掉了 public，就造成了配置正确，却怎样也不生效
