帮助文档：
https://docs.spring.io/spring-boot/docs/2.1.0.BUILD-SNAPSHOT/reference/htmlsingle/#boot-feature-logging
log4j.properties转换logback.xml
https://logback.qos.ch/translator/
https://logback.qos.ch/manual/index.html
转换前代码：
### 设置###
log4j.rootLogger = debug,stdout,D,E
### 输出信息到控制抬 ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
### 输出DEBUG 级别以上的日志到=E://logs/error.log ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = E://logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
### 输出ERROR 级别以上的日志到=E://logs/error.log ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File =E://logs/error.log
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
1.添加pom.xml的依赖
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>top.ytheng</groupId> <artifactId>springboot-demo</artifactId> <version>0.0.1</version> <packaging>jar</packaging> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.5.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!-- 热部署 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> <scope>true</scope> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.2</version> <scope>runtime</scope> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.6</version> </dependency> </dependencies> <build> <!-- 打包的名称 --> <finalName>myspringboot</finalName> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
2.添加lockback-spring.xml配置文件
<?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern> %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n </pattern> </encoder> </appender> <!-- 日志记录器，日期滚动记录 --> <appender name="fileInfoApp" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- 正在记录的日志文件的路径及文件名 --> <!-- <file>${LOG_PATH}/warn/log_warn.log</file> --> <!-- 日志记录器的滚动策略，按日期，按大小记录 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 归档的日志文件的路径，例如今天是2013-12-21日志，当前写的日志文件路径为file节点指定，可以将此文件与file指定文件路径设置为不同路径，从而将当前日志文件或归档日志文件置不同的目录。 而2013-12-21的日志文件在由fileNamePattern指定。%d{yyyy-MM-dd}指定日期格式，%i指定索引 --> <fileNamePattern>app_log/log/log-error-%d{yyyy-MM-dd}.%i.log</fileNamePattern> <!-- 表示只保留最近30天的日志，以防止日志填满整个磁盘空间。--> <maxHistory>30</maxHistory> <!--用来指定日志文件的上限大小，例如设置为1GB的话，那么到了这个值，就会删除旧的日志。--> <totalSizeCap>1GB</totalSizeCap> <!-- 除按日志记录之外，还配置了日志文件不能超过2M，若超过2M，日志文件会以索引0开始，命名日志文件，例如log-error-2013-12-21.0.log --> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>2MB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> <!-- 追加方式记录日志 --> <append>true</append> <!-- 日志文件的格式 --> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <pattern>===%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %logger Line:%-3L - %msg%n</pattern> <charset>utf-8</charset> </encoder> <!-- 此日志文件只记录war级别的 --> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <!-- 只保留error日志 --> <!-- level:debug,info,warn,error --> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <!-- root节点要放到appender之后 --> <root level="INFO"> <appender-ref ref="STDOUT" /> <appender-ref ref="fileInfoApp" /> </root> </configuration>
3.添加控制器
package top.ytheng.demo.controller; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping("/api/v1/log") public class LogController { private Logger logger = LoggerFactory.getLogger(this.getClass()); @GetMapping("/test") public Object test() { logger.debug("this is debug level"); logger.info("this is info level"); logger.warn("this is warn level"); logger.error("this is error level"); return "success"; } }
4.添加启动类
package top.ytheng.demo; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication //等于下面3个 //@SpringBootConfiguration //@EnableAutoConfiguration //@ComponentScan public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
5.右键项目Rum As启动，访问地址
http://localhost:8080/api/v1/log/test
