记录项目统一配置日志：

copy logback.xml到resources目录下

更改logback.xml要输出的日志文件的名字：

<configuration scan="true" scanPeriod="10 seconds">

    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</Pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>

    <property name="LOG_PATH" value="log"/>

    <!-- 时间滚动输出 level为 INFO 日志 -->
    <appender name="INFO_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>${LOG_PATH}/项目名.log</File>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
            <charset>UTF-8</charset>
        </encoder>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>2</maxHistory>
        </rollingPolicy>
    </appender>

    <!-- 时间滚动输出 level为 ERROR 日志 -->
    <appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
            <charset>UTF-8</charset>

            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>2</maxHistory>
        </rollingPolicy>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
    </appender>

    <logger name="org.springframework.web" level="INFO"/>
    <logger name="org.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor" level="INFO"/>
    <logger name="com.jk" level="DEBUG"/>
    <!--<logger name="org.mybatis">-->
    <!--<level value="TRACE"/>-->
    <!--</logger>-->

    <root level="info">
        <appender-ref ref="INFO_FILE"/>
        <appender-ref ref="ERROR_FILE"/>
        <appender-ref ref="CONSOLE"/>
    </root>

</configuration>

在properties文件中配置日志：

logging.path=*******log  //不重要
logging.config=classpath:logback.xml

到此，日志基本上已配置完成，

在接口中可以手动打印日志：

public static Logger logger = LoggerFactory.getLogger(Utils.class);

logger.info();//在需要记录的地方使用
logger.error();

也可以自动打印日志，主要打印接口的入参和出参：

首先在启动类上加上如下注解：

@ServletComponentScan

copy过滤器及其附属文件：

日志自动打印结果：

可以打印已经配置的发起请求的url和请求参数，以及返回数据。

以上某些文件均由某java大佬编写。

期待指正和补充。
