有时候spring boot项目想要监听controller类的请求记录，可以通过aop方式处理。

## 引入maven依赖 ##

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

## 配置AOP切面配置类 ##

    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.annotation.Before;

    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpSession;
    import java.util.Arrays;

    @Aspect
    @Component
    public class LogAspect {
        private final static Logger logger = LoggerFactory.getLogger(LogAspect.class);
    
        @Pointcut("execution(public * cn.test.controller.*.*(..))")
        public void webLog() {
        }
    
        @Before("webLog()")
        public void deBefore(JoinPoint joinPoint) throws Throwable {
            // 接收到请求，记录请求内容
            ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
            HttpServletRequest request = attributes.getRequest();
            HttpSession session = request.getSession();
            String username = (String) session.getAttribute("username");
            // 记录下请求内容
            logger.info("USERNAME : " + username);
            logger.info("IP : " + request.getRemoteAddr());
            logger.info("URL : " + request.getRequestURL().toString() + " HTTP_METHOD : " + request.getMethod());
            logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
            logger.info("INPUT　ARGS : " + Arrays.toString(joinPoint.getArgs()));
        }
    
        /*@AfterReturning(returning = "ret", pointcut = "webLog()") public void doAfterReturning(Object ret) throws Throwable { // 处理完请求，返回内容 logger.info("方法的返回值 : " + ret); } //后置异常通知 @AfterThrowing("webLog()") public void throwss(JoinPoint jp) { logger.info("方法异常时执行....."); } //后置最终通知,final增强，不管是抛出异常或者正常退出都会执行 @After("webLog()") public void after(JoinPoint jp) { logger.info("方法最后执行....."); } //环绕通知,环绕增强，相当于MethodInterceptor @Around("webLog()") public Object arround(ProceedingJoinPoint pjp) { logger.info("方法环绕start....."); try { Object o = pjp.proceed(); logger.info("方法环绕proceed，结果是 :" + o); return o; } catch (Throwable e) { e.printStackTrace(); return null; } }*/
