按照：error、info、warn進行分類：

每個文件里面按日期進行分類：

其中對應(yīng)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"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.10.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.example</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><name>demo</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

最關(guān)鍵的logback-spring.xml如下：

<?xml version="1.0" encoding="UTF-8" ?> <configuration><!--輸出日志格式--><appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender"><layout class="ch.qos.logback.classic.PatternLayout"><pattern>%d - %msg%n</pattern></layout></appender><!--只保存info日志--><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><!--滾動輸出策略--><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><!--路徑--><fileNamePattern>D:/logs/info/info.%d.log</fileNamePattern></rollingPolicy></appender><!--只保存warn日志--><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><!--滾動輸出策略--><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><!--路徑--><fileNamePattern>D:/logs/warn/warn.%d.log</fileNamePattern></rollingPolicy></appender><!--只保存error日志--><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><!--滾動輸出策略--><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><!--路徑--><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>

調(diào)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";} }
