切面相关注解：
@Aspect : 声明该类为一个注解类
@Pointcut : 定义一个切点
@Before : 在切点之前执行
@After : 在切点之后执行 不管目标方法是否执行成功
@AfterReturning : 切点返回内容后执行代码，可以对切点的返回值进行封装
@AfterThrowing : 切点抛出异常后执行
@Around : 环绕，在切点前后执行代
1.自定义注解：
@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface timingAnnotation {
}
2.切面类
@Aspect
@Component
@Slf4j
public class AspectDemo {
@Pointcut("@annotation(com.wl.demo.demos.aop.timingAnnotation)")
public void pointCut() {
}
@Before("pointCut()")
public void doBefore(JoinPoint joinPoint) {
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
log.info("IP: {}", request.getRemoteAddr());
log.info("URL: {}", request.getRequestURL().toString());
log.info("HTTP Method: {}", request.getMethod());
log.info("Class Method: {}.{}", joinPoint.getSignature().getDeclaringTypeName(), joinPoint.getSignature().getName());
}
@Around("pointCut()")
public Object doAround(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
long startTime = System.currentTimeMillis();
MethodSignature methodSignature = (MethodSignature) proceedingJoinPoint.getSignature();
Object proceed = proceedingJoinPoint.proceed();
long endTime = System.currentTimeMillis();
log.info("[方法耗时]" + methodSignature.getDeclaringTypeName() + "." + methodSignature.getMethod().getName() + " 耗时: " + (endTime - startTime) + "毫秒");
return proceed;
}
@After("pointCut()")
public void doAfter(JoinPoint joinPoint) {
log.info("目标方法执行完之后执行");
}
@AfterThrowing(pointcut = "pointCut()", throwing = "e")
public void doAfterThrow(JoinPoint joinPoint, RuntimeException e) {
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
log.info("HTTP Method: {}", request.getMethod());
log.info("Class Method: {}.{}", joinPoint.getSignature().getDeclaringTypeName(), joinPoint.getSignature().getName());
}
}
注：引入aspect 需要引入jar:
<!--引入aop aspectj-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
<scope>test</scope>
</dependency>
