Spring切面编程(AOP)

一、按指定注解切人

@Slf4j
@Aspect
@Component
public class MemberLoginAOPComponent {
    @AfterReturning(value = "@annotation(com.alanchen.annotation.SignMemberLoginLog)", returning = "result")
    public void afterReturning(JoinPoint joinPoint, Object result){
        Result<Oauth2TokenDto> loginResult = (Result<Oauth2TokenDto>) result;
        if (loginResult.getCode() != ResultCode.SUCCESS.getCode() || null == loginResult.getData()) {
            return;
        }
        Object[] objects = joinPoint.getArgs();
        Map<String, Object> mapParam = new HashMap<>();
        if (null != objects) {
            mapParam = BeanUtil.beanToMap(objects[0]);
        }

        Oauth2TokenDto oauth2TokenDto = loginResult.getData();

        // 其他逻辑
    }
}

二、按方法切入

@Component
@Aspect
@Slf4j
public class MicrospotAspect {
    
    @Pointcut(
            "execution(public * com.alanchen.*.controller.*Controller.*(..))" +
                    "|| execution(public * com.alanchen.*.controller.op.BackendMemberCertMerController.*(..))" +
                    "&& !execution(public * com.alanchen.*.controller.ApiLogController.*(..))" +
                    "&& !execution(public * com.alanchen.*.controller.SensitiveWordController.selectList(..))" +
                    "&& !execution(public * com.alanchen.*.controller.SensitiveWordController.test(..))" +
                    "&& !execution(public * com.alanchen.*.*Controller.UserController.*(..))"
    )
    public void aspectCut() {}

    /**
     * 正常执行
     *
     * @param joinPoint 切入点
     * @param result
     * @throws Throwable 异常信息
     */
    @AfterReturning(value = "aspectCut()", returning = "result")
    public void afterReturning(JoinPoint joinPoint, Object result) throws Exception {
        if(result == null){
            return;
        }

        if(result instanceof Result){
            Result<Object> createResult = (Result<Object>) result;
            if(createResult.getCode() !=ResultCode.SUCCESS.getCode()){
                return;
            }
        }else{
            return;
        }

        try{
            ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
            if (null != requestAttributes) {
                HttpServletRequest request = requestAttributes.getRequest();
                String requestUri = request.getRequestURI();
                // 取到参数
            }
        } catch (Exception ex) {
            log.error(ex.getMessage());
        }
    }
}
