【this调用方法使得aop失效】https://blog.csdn.net/z69183787/article/details/113888646

今天在使用Spring Cache时，调用@CachePut修饰的方法发现并不能存入redis，且没有任何报错，一番学习后发现，是由于this调用被@Sync @Transactional @Cacheable等注解修饰的方法使得AOP失效，导致无法缓存。

        log.info("获取验证码，邮箱: {}", phone);
        return null;
    }


    @Override
    public Result sendMsg(User user, HttpServletRequest request) {

        // 获取手机号
        String phone = user.getPhone();
        if (!StringUtils.isEmpty(phone)) {

            // 生成4位验证码
            String code = ValidateCodeUtils.generateValidateCode(4).toString();
            log.info("验证码: {}", code);

            // 发送邮箱
            mailUtils.sendMail(phone, code);

            // 将验证码存储到 redis中 有效期 3 分钟
            //redisTemplate.opsForValue().set(phone, code, 5, TimeUnit.MINUTES);
            redisSaveCode(phone, code);
            return Result.success(code, null); //正常调用，但并没有缓存，即注解没有生效
        }
        return Result.fail("非法手机号");
    }
}

• 注入ApplicationContext
• 使用 applicationContext.getBean(UserServiceImpl.class).redisSaveCode(phone,code);来取代this调用
