Java切面的使用，记录请求日志

// 定义一个切面
@Aspect
@Configuration
public class LogRecordAspect {
	
    private static final Logger logger = LoggerFactory.getLogger(LogRecordAspect.class);

    // 定义切入点
    @Pointcut("execution(* com.dome.spring.controller..*.*(..))")
    public void controllerPointcut() {
    }

    // 定义事件触发节点，引用切入点
    @Around("controllerPointcut()")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        RequestAttributes ra = RequestContextHolder.getRequestAttributes();
        ServletRequestAttributes sra = (ServletRequestAttributes) ra;
        HttpServletRequest request = sra.getRequest();
        String url = request.getRequestURL().toString();
        String method = request.getMethod();
        Map<String, String> paramMap = new HashMap<>();
        Enumeration<String> paramNames = request.getParameterNames();
        while (paramNames.hasMoreElements()) {
			String name = paramNames.nextElement();
			String value = request.getParameter(name);
			paramMap.put(name, value);
		}
        logger.info("请求开始===地址:{}", url);
        logger.info("请求开始===类型:{}", method);
        logger.info("请求开始===参数:{}", JSON.toJSONString(paramMap));
        // result的值就是被拦截方法的返回值
        Object result = pjp.proceed();
        logger.info("请求结束===返回值:{}", JSON.toJSONString(result));
        return result;
    }
}
