理论和日志的重要不需要重复，各位都明白，企业中甩锅 查询记录 必要的东西，直接贴上代码案例

logback的配置文件（按天存储日志文件）
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="60 seconds" debug="false">
<contextName>logback</contextName>
<!--输出到控制台-->
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<!--按天生成日志-->
<appender name="logFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
<Prudent>true</Prudent>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>
applog/%d{yyyy-MM-dd}/%d{yyyy-MM-dd}.log
</FileNamePattern>

<layout class="ch.qos.logback.classic.PatternLayout">

</appender>
<logger name="com.bootdo" additivity="false">

自定义日志注解类
package com.hw.common;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Log {
String value() default "";
}
用于将日志保存至数据库的配置类
package com.hw.common;
import com.hw.doman.LogDO;
import com.hw.doman.UserDO;
import com.hw.service.LogService;
import com.hw.util.HttpContextUtils;
import com.hw.util.IPUtils;
import com.hw.util.JSONUtils;
import com.hw.util.ShiroUtils;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.lang.reflect.Method;
import java.util.Date;
import javax.servlet.http.HttpServletRequest;
@Aspect
@Component
public class LogAspect {
@Autowired
LogService logService;
@Pointcut("@annotation(com.hw.common.Log)")
public void logPointCut() {
}
@Around("logPointCut()")
public Object around(ProceedingJoinPoint point) throws Throwable {
long beginTime = System.currentTimeMillis();
// 执行方法
Object result = point.proceed();
// 执行时长(毫秒)
long time = System.currentTimeMillis() - beginTime;
//异步保存日志
saveLog(point, time);
return result;
}
void saveLog(ProceedingJoinPoint joinPoint, long time) throws InterruptedException {
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();
LogDO sysLog = new LogDO();
Log syslog = method.getAnnotation(Log.class);
if (syslog != null) {
// 注解上的描述
sysLog.setOperation(syslog.value());
}
// 请求的方法名
String className = joinPoint.getTarget().getClass().getName();
String methodName = signature.getName();
sysLog.setMethod(className + "." + methodName + "()");
// 请求的参数
Object[] args = joinPoint.getArgs();
try {
String params = JSONUtils.beanToJson(args[0]).substring(0, 4999);
sysLog.setParams(params);
} catch (Exception e) {
}
// 获取request
HttpServletRequest request = HttpContextUtils.getHttpServletRequest();
// 设置IP地址
sysLog.setIp(IPUtils.getIpAddr(request));
// 用户名
//
UserDO currUser = ShiroUtils.getUser();
currUser.setUsername("test");
if (null == currUser) {
if (null != sysLog.getParams()) {
sysLog.setUserId(-1L);
sysLog.setUsername(sysLog.getParams());
} else {
sysLog.setUserId(-1L);
sysLog.setUsername("获取用户信息为空");
}
} else {
//
sysLog.setUserId( ShiroUtils.getUserId());
//
sysLog.setUsername(ShiroUtils.getUser().getUsername());
}
sysLog.setTime((int) time);
// 系统当前时间
Date date = new Date();
sysLog.setGmtCreate(date);
// 保存系统日志
logService.save(sysLog);
}
}
将日志信息打印的配置类
package com.hw.common;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Around;
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;
import java.util.Arrays;
import javax.servlet.http.HttpServletRequest;
@Aspect
@Component
public class WebLogAspect {
private static final Logger logger = LoggerFactory.getLogger(WebLogAspect.class);
@Pointcut("execution( * com.hw.controller.*.*(..))")//两个..代表所有子目录，最后括号里的两个..代表所有参数
public void logPointCut() {
}
@Before("logPointCut()")
public void doBefore(JoinPoint joinPoint) throws Throwable {
// 接收到请求，记录请求内容
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
// 记录下请求内容
logger.info("请求地址 : " + request.getRequestURL().toString());
logger.info("HTTP METHOD : " + request.getMethod());
// 获取真实的ip地址
//logger.info("IP : " + IPAddressUtil.getClientIpAddress(request));
logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "."
+ joinPoint.getSignature().getName());
logger.info("参数 : " + Arrays.toString(joinPoint.getArgs()));
// loggger.info("参数 : " + joinPoint.getArgs());
}
@AfterReturning(returning = "ret", pointcut = "logPointCut()")// returning的值和doAfterReturning的参数名一致
public void doAfterReturning(Object ret) throws Throwable {
// 处理完请求，返回内容(返回值太复杂时，打印的是物理存储空间的地址)
logger.debug("返回值 : " + ret);
}
@Around("logPointCut()")
public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
long startTime = System.currentTimeMillis();
Object ob = pjp.proceed();// ob 为方法的返回值
logger.info("耗时 : " + (System.currentTimeMillis() - startTime));
return ob;
}
}
用于测试的controller类
package com.hw.controller;
import com.hw.common.Log;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestController {
@Log("/测试1")
@GetMapping("/test")
public String test() {
return "test";
}
}
完事直接贴上效果图：
日志打印存储
日志文件按天存储
数据库的存储
