这是为了系统健壮性的一种保证，用filter把每一个请求都打印出来，可以提高调试开发的效率
以下是我配置AOP的方法
在pom.xml里面配置依赖
<![CDATA[
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
]]>
然后建一个过滤器，对我们的请求进行拦截和打印
创建一个文件夹filter类WebLogAspect
<![CDATA[
package com.fish.springboot.mall.filter;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.Arrays;
import javax.servlet.http.HttpServletRequest;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
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;
/**
* 描述： 打印请求和响应信息
*/
@Aspect
@Component
public class WebLogAspect {
private final Logger log = LoggerFactory.getLogger(WebLogAspect.class);
@Pointcut("execution(public * com.fish.springboot.mall.controller.*.*(..)))")
public void webLog() {
}
@Before("webLog()")
public void doBefore(JoinPoint joinPoint) {
//收到请求，记录请求内容
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder
.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
log.info("URL : " + request.getRequestURL().toString());
log.info("HTTP_METHOD :" + request.getMethod());
log.info("IP : " + request.getRemoteAddr());
log.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "."
+ joinPoint.getSignature().getName());
log.info("ARGS : " + Arrays.toString(joinPoint.getArgs()));
}
@AfterReturning(returning = "res", pointcut = "webLog()")
public void doAfterReturning(Object res) throws JsonProcessingException {
//处理完请求，返回内容
log.info("RESPONSE : " + new ObjectMapper().writeValueAsString(res));
}
}
]]>
能打印出来一些日志
这些内容全都能打印到日志里，对以后的排除问题有很大的帮助
