lengthuo实战–aop切面编程

1 老套路 条件 配置

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

第二使用讲解

//aop  第一步添加扩展spring-boot-starter-aop
//第二 添加下面类（3个方法追常用） @Before @After @AfterReturning

@Aspect
@Component
public class HttpAspect {

    private final static Logger logger = LoggerFactory.getLogger(HttpAspect.class);

    @Pointcut("execution(public * com.lishuo.demo1.controllers.TestController.*(..))")
    public void log() {
    }

    @Before("log()")
    public void doBefore(JoinPoint joinPoint) {
        ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = servletRequestAttributes.getRequest();
        //请求url
        logger.info("url={}", request.getRequestURL());
        //请求method
        logger.info("method={}", request.getMethod());
        //请求ip
        logger.info("ip={}", request.getRemoteAddr());
        //获取类方法     类名 + 类方法
        logger.info("class_method={}", joinPoint.getSignature().getDeclaringTypeName() +
                "." + joinPoint.getSignature().getName());
        //参数
        logger.info("args={}", joinPoint.getArgs());
    }

    // @After("log()")

    //打印返回的内容
    @AfterReturning(returning = "object", pointcut = "log()")
    public void doAfter(Object object) {
        logger.info("response={}", object.toString());
    }


}
