在SpringBoot中使用AOP获取HttpServletRequest、HttpSession 内容

POM.xml添加AOP依赖：

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

然后在拦截器类中添加切面代码：

package com.tbms2;
    
    import java.util.Collections;
    import java.util.Enumeration;
    import java.util.HashMap;
    import java.util.Map;
    
    import javax.servlet.http.HttpServletRequest;
    
    import org.aspectj.lang.JoinPoint;
    import org.aspectj.lang.Signature;
    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.annotation.Before;
    import org.aspectj.lang.annotation.Pointcut;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.stereotype.Component;
    import org.springframework.web.context.request.RequestAttributes;
    import org.springframework.web.context.request.RequestContextHolder;
    import com.alibaba.fastjson.JSON;
    
    @Component
    @Aspect
    public class WebControllerAop {
    
        Logger logger = LoggerFactory.getLogger(WebControllerAop.class);
        
        @Pointcut("execution(* com.tbms2.web..*.json*(..))")
        public void executeService(){
            
        }
        
        @Before("executeService()")
        public void doBeforeAdvice(JoinPoint joinPoint) {
            logger.info("==> json方法调用开始...");
            //获取目标方法的参数信息  
            Object[] obj = joinPoint.getArgs();  
            //AOP代理类的信息  
            joinPoint.getThis();  
            //代理的目标对象  
            joinPoint.getTarget();  
            //用的最多 通知的签名  
            Signature signature = joinPoint.getSignature();  
            //代理的是哪一个方法  
            logger.info("==> 代理的是哪一个方法 :"+signature.getName());
            //AOP代理类的名字  
            logger.info("==> AOP代理类的名字:"+signature.getDeclaringTypeName());
            //AOP代理类的类（class）信息  
            signature.getDeclaringType();  
            //获取RequestAttributes  
            RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();  
            //从获取RequestAttributes中获取HttpServletRequest的信息  
            HttpServletRequest request = (HttpServletRequest) requestAttributes.resolveReference(RequestAttributes.REFERENCE_REQUEST);  
            logger.info("==> 请求者的IP："+request.getRemoteAddr());
            //如果要获取Session信息的话，可以这样写：  
            //HttpSession session = (HttpSession) requestAttributes.resolveReference(RequestAttributes.REFERENCE_SESSION);  
            Enumeration<String> enumeration = request.getParameterNames();  
            Map<String,String> parameterMap = new HashMap<String,String>();
            while (enumeration.hasMoreElements()){
                String parameter = enumeration.nextElement();  
                parameterMap.put(parameter,request.getParameter(parameter));  
            }  
            String str = JSON.toJSONString(parameterMap);  
            if(obj.length > 0) {  
                logger.info("==> 请求的参数信息为："+str);
            }
        }
        
    }
