2.整合logback

一、logback.xml

<configuration>
    <!--本文主要输出日志为控制台日志，系统日志，sql日志，异常日志-->
    <!-- %m输出的信息,%p日志级别,%t线程名,%d日期,%c类的全名,,,, -->
    <!--控制台-->
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d %p (%file:%line\)- %m%n</pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>

    <!--系统info级别日志-->
    <!--<File> 日志目录，没有会自动创建-->
    <!--<rollingPolicy>日志策略，每天简历一个日志文件，或者当天日志文件超过64MB时-->
    <!--encoder 日志编码及输出格式-->
    <appender name="fileLog"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>log/file/fileLog.log</File>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/file/fileLog.log.%d.%i</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <!-- or whenever the file size reaches 64 MB -->
                <maxFileSize>64 MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
        <encoder>
            <pattern>
                %d %p (%file:%line\)- %m%n
            </pattern>
            <charset>UTF-8</charset>
            <!-- 此处设置字符集 -->
        </encoder>
    </appender>

    <!--sql日志-->
    <appender name="sqlFile"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>log/sql/sqlFile.log</File>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/sql/sqlFile.log.%d.%i</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <!-- or whenever the file size reaches 64 MB -->
                <maxFileSize>64 MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
        <!--对记录事件进行格式化。负责两件事，一是把日志信息转换成字节数组，二是把字节数组写入到输出流。-->
        <encoder>
            <!--用来设置日志的输入格式-->
            <pattern>
                %d %p (%file:%line\)- %m%n
            </pattern>
            <charset>UTF-8</charset>
            <!-- 此处设置字符集 -->
        </encoder>
    </appender>


    <!--异常日志-->
    <appender name="errorFile"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>log/error/errorFile.log</File>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/error/errorFile.%d.log.%i</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <!-- or whenever the file size reaches 64 MB -->
                <maxFileSize>64 MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
        <!--对记录事件进行格式化。负责两件事，一是把日志信息转换成字节数组，二是把字节数组写入到输出流。-->
        <encoder>
            <!--用来设置日志的输入格式-->
            <pattern>
                %d %p (%file:%line\)- %m%n
            </pattern>
            <charset>UTF-8</charset>
            <!-- 此处设置字符集 -->
        </encoder>
        <!--
            日志都在这里 过滤出 error
            使用 try {}catch (Exception e){} 的话异常无法写入日志，可以在catch里用logger.error()方法手动写入日志
            -->
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>
    <!--  日志输出级别 -->
    <!--All\DEBUG\INFO\WARN\ERROR\FATAL\OFF-->
    <!--打印info级别日志，分别在控制台，fileLog，errorFile输出
        异常日志在上面由过滤器过滤出ERROR日志打印
    -->
    <root level="INFO">
        <appender-ref ref="fileLog" />
        <appender-ref ref="console" />
        <appender-ref ref="errorFile" />
    </root>

    <!--打印sql至sqlFile文件日志-->
    <logger name="com.dolphin.mapper" level="DEBUG" additivity="false">
        <appender-ref ref="console" />
        <appender-ref ref="sqlFile" />
    </logger>
</configuration>

二、application.yml

#logback
logging:
  config: classpath:log/logback.xml

三、切面记录所有service方法调用日志

· pom.xml

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-aop -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
            <version>2.3.0.RELEASE</version>
        </dependency>

WebLogAspect

package com.miaoshaProject.aop;

import lombok.extern.slf4j.Slf4j;
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.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

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

/**
 * @Author wangshuo
 * @Date 2022/5/4, 9:32
 * 切面记录日志
 */
@Aspect
@Component
@Slf4j
public class WebLogAspect {

    @Pointcut("execution(public * com.miaoshaProject.service.*.*(..))")
    public void webLog() {
    }

    @Before("webLog()")
    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
        log.info("URL : " + request.getRequestURL().toString());
        //log.info("HTTP_METHOD : " + request.getMethod());
        log.info("IP : " + InetAddress.getLocalHost().getHostAddress());
        Enumeration<String> enu = request.getParameterNames();
        while (enu.hasMoreElements()) {
            String name = (String) enu.nextElement();
            log.info("参数name:{},value:{}", name, request.getParameter(name));
        }
    }

    @AfterReturning(returning = "ret", pointcut = "webLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        // 处理完请求，返回内容
        //log.info("RESPONSE : " + ret);
    }
}

四、单独记录demo

 

 

@Override
    public UserModel getById(Integer id) {

        //调用mapper获取到对应的UserDO
        UserDO userDO = userDOMapper.selectByPrimaryKey(id);
        log.warn("UserServiceImpl --- getById --- selectByPrimaryKey{}",id);
        if (userDO == null) {
            return null;
        }
        //通过用户id获取用户的加密密码信息
        UserPasswordDO userPasswordDO = userPasswordDOMapper.selectByUserId(id);
        return convertFromDataObject(userDO, userPasswordDO);
    }
