springboot獲取request請求的原始url與post參數

獲取請求的完整url與請求參數，post的body中的數據，最根本的是利用HttpServletRequest ，來獲取信息，然後是可以使用不同的方式，比如aop攔截，spring中已有過濾器類，方便使用

• 使用springboot的aop攔截

import java.util.Enumeration;
import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
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.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

@Aspect
@Component
public class MyAspect {
	private final static Logger logger = LoggerFactory.getLogger(MyAspect.class);

	//這個切點的表達式需要根據自己的項目來寫
	@Pointcut("execution(public * com..*(..))")
	public void log() {
		
	}
	
	@Before("log()")
	public void doBefore(JoinPoint joinPoint) {
		logger.info("aop doBefore..");
		ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
		HttpServletRequest request = attributes.getRequest();
		
		logger.info("url={}",request.getRequestURI());
		logger.info("method={}", request.getMethod());
		logger.info("ip={}", request.getRemoteAddr());
		logger.info("classMethod={}", joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
		Enumeration<String> paramter = request.getParameterNames();
		while (paramter.hasMoreElements()) {
			String str = (String) paramter.nextElement();
			logger.info(str + "={}", request.getParameter(str));
		}
		
	}
	
	@After("log()")
	public void doAfter() {
		logger.info("aop doAfter");
	}
}

• 使用filter攔截器

@Bean
    public Filter loggingFilter(){
        AbstractRequestLoggingFilter f = new AbstractRequestLoggingFilter() {

            @Override
            protected void beforeRequest(HttpServletRequest request, String message) {
                System.out.println("beforeRequest: " +message);

                StringBuilder msg = new StringBuilder();
                ServletRequest copiedRequest = new HttpServletRequestWrapper(request);
                byte[] requestBody;
                try {
                    requestBody = IOUtils.toByteArray(request.getInputStream());
                    msg.append(new String(requestBody));
                } catch (IOException e) {
                    e.printStackTrace();
                }
                System.out.println("msg:"+msg);
            }

            @Override
            protected void afterRequest(HttpServletRequest request, String message) {
                System.out.println("afterRequest: " +message);
            }
        };
        f.setIncludeClientInfo(true);
        f.setIncludePayload(true); // 在afterRequest的message最後會有post的body
        f.setIncludeQueryString(true);
        f.setIncludeHeaders(true);
        f.setMaxPayloadLength(10000);

        f.setBeforeMessagePrefix("BEFORE REQUEST  [>");
        f.setBeforeMessageSuffix("<]\n");
        f.setAfterMessagePrefix("AFTER REQUEST    [>");
        f.setAfterMessageSuffix("<]\n");


        return f;
    }

• 同類的還有CommonsRequestLoggingFilter
  好處：可以快速自定義攔截哪些url在shouldLog方法配置

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CommonsRequestLoggingFilter;
 
import javax.servlet.http.HttpServletRequest;
 
 
@Configuration
public class LoggingFilter extends CommonsRequestLoggingFilter {
 
    private final Logger logger = LoggerFactory.getLogger(LoggingFilter.class);
    private static long beforeTime;
    private static long afterTime;
 
    public MyDeskCalendarLoggingFilter(){
        super.setIncludeClientInfo(false);
        super.setIncludeHeaders(false);
        super.setIncludePayload(true);
        super.setMaxPayloadLength(2000);
        super.setIncludeQueryString(true);
        
    }
 
    @Override
    protected boolean shouldLog(HttpServletRequest request) {
        String requestURI = request.getRequestURI();
        // Checks if request matches /api/calendarCompletionDate
        boolean shouldLog = requestURI.matches("^/api\\/calendarCompletionDate$");
 
        if (shouldLog) {
            long currentUserId = SecurityUtils.getCurrentAccountUserId();
            String method = request.getMethod();
            super.setBeforeMessagePrefix("Before request [" + method + "," + "currentUserId:" + currentUserId + ","); //Default is just Before request
            super.setAfterMessagePrefix("After request [" + method + "," + "currentUserId:" + currentUserId + ",");   //Default is just After request
        }
        return shouldLog;
    }
 
    @Override
    protected void beforeRequest(HttpServletRequest request, String message) {
        beforeTime = System.currentTimeMillis();
        MemoryLogUtil.logUsed("beforeRequest");//only shows at this moment in time
        super.beforeRequest(request, message);
    }
 
    @Override
    protected void afterRequest(HttpServletRequest request, String message) {
        afterTime = System.currentTimeMillis();
        logger.info("afterRequest: Time taken: " + (afterTime-beforeTime) + " in milliseconds");
        MemoryLogUtil.logUsed("afterRequest");//only shows at this moment in time
        super.afterRequest(request, message);
    }
}
