如上图，每天会生成一个新的日志文件，然后日志进行分类，我这里只对error和info进行分类。
怎么做呢？
首先，在resource目录创建一个新文件，取名logback-spring.xml

在这里插入图片描述


<?xml version="1.0" encoding="UTF-8" ?>
<configuration >
    <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>
                %d - %msg%n
            </pattern>
        </layout>
    </appender>

    <appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>
                ERROR
            </level>
            <onMatch>DENY</onMatch>
            <onMismatch>ACCEPT</onMismatch>
        </filter>
        <encoder>
            <pattern>
                %msg%n
            </pattern>
        </encoder>
        <!--  滚动策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!--   路径-->
            <fileNamePattern>
            /var/log/tomcat/sell/info.%d.log
            </fileNamePattern>
        </rollingPolicy>
    </appender>

    <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>
                ERROR
            </level>
        </filter>
        <encoder>
            <pattern>
                %msg%n
            </pattern>
        </encoder>
        <!--  滚动策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--   路径-->
            <fileNamePattern>
                /var/log/tomcat/sell/error.%d.log
            </fileNamePattern>
        </rollingPolicy>
    </appender>

    <root level="info">
        <appender-ref ref="consoleLog" />
        <appender-ref ref="fileInfoLog" />
        <appender-ref ref="fileErrorLog" />

    </root>
</configuration>

单例测试：


import lombok.Data;
import lombok.extern.slf4j.Slf4j;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
@Slf4j
@Data
public class LoggerTest {

    @Test
    public void test1(){
        String name="laomi";
        String password="123456";
        log.info("debug.....");
        log.info("info.....");
        log.error("error....");
        log.info("name:{}, password:{}",name,password);

    }
}

添加依赖：


 <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <scope>test</scope>
 </dependency>
