按照：error、info、warn进行分类：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxNzg0NDI3NjE_size_16_color_FFFFFF_t_70][]

每个文件里面按日期进行分类：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxNzg0NDI3NjE_size_16_color_FFFFFF_t_70 1][]

其中对应的Maven如下：

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                </plugin>
            </plugins>
        </build>
    
    </project>

最关键的logback-spring.xml如下：

<?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>INFO</level>
                <onMatch>ACCEPT</onMatch>
                <onMismatch>DENY</onMismatch>
            </filter>
            <encoder>
                <pattern>
                    %d - %msg%n
                </pattern>
            </encoder>
            
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <fileNamePattern>D:/logs/info/info.%d.log</fileNamePattern>
            </rollingPolicy>
        </appender>
    
        
        <appender name="fileWarnLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <filter class="ch.qos.logback.classic.filter.LevelFilter">
                <level>WARN</level>
                <onMatch>ACCEPT</onMatch>
                <onMismatch>DENY</onMismatch>
            </filter>
            <encoder>
                <pattern>
                    %d - %msg%n
                </pattern>
            </encoder>
            
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <fileNamePattern>D:/logs/warn/warn.%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>
                    %d - %msg%n
                </pattern>
            </encoder>
            
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <fileNamePattern>D:/logs/error/error.%d.log</fileNamePattern>
            </rollingPolicy>
        </appender>
    
        <root level="info">
            <appender-ref ref="consoleLog"/>
            <appender-ref ref="fileInfoLog"/>
            <appender-ref ref="fileWarnLog"/>
            <appender-ref ref="fileErrorLog"/>
        </root>
    
    </configuration>

调用如下：

package com.example.demo;
    
    import lombok.extern.slf4j.Slf4j;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @Slf4j
    public class controller {
    
        @GetMapping("/test1")
        public String test1(){
    
            log.info("test1");
            return "test1";
        }
    
        @GetMapping("/test2")
        public String test2(){
    
            log.error("test2");
            return "test2";
        }
    
    
        @GetMapping("/test3")
        public String test3(){
    
            log.debug("test3");
            return "test3";
        }
    }
