第一步:pom 文件
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.payease</groupId> <artifactId>sell</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>sell</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.8.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> <!-- ===================== mysql驱动 ======================== --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- ===================== jpa ======================== --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <!-- ===================== @Getter @Setter @Slf4j @Data ======================== --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
第二步:你的测试类
package com.payease; import lombok.extern.slf4j.Slf4j; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner; /** * Created by liuxiaoming on 2017/11/8. */ @RunWith(SpringRunner.class) @SpringBootTest @Slf4j //@Data public class LoggerTest { //private final Logger logger = LoggerFactory.getLogger(LoggerTest.class); @Test public void test1(){ // logger.debug("debug ..."); // logger.info("info ..."); // logger.error("error ..."); //日志中打印变量的使用样例 String name = "liuxiaoming"; String password = "123456"; log.debug("debug ..."); //@Slf4j log.info("info ..."+"name:" + name + " ,password:" + password); //@Slf4j log.error("error ..."+"name:{} ,password:{}",name,password); //@Slf4j } }
第三步:配置文件application.yml文件中的配置
spring: datasource: driver-class-name: com.mysql.jdbc.Driver username: root password: 1234 url: jdbc:mysql://127.0.0.1/sell?characterEncoding=utf-8&useSSL=false jpa: show-sql: true server: context-path: /sell logging: pattern: console: "%d - %msg%n" #日志格式 日期 - 信息 空格 # path: /Users/liuxiaoming/Documents/ideawork/sell_log #日志路径 默认名字spring.log file: /Users/liuxiaoming/Documents/ideawork/sell_log/sell.log #日志文件+路径 level: #日志级别 com.payease.LoggerTest: debug #日志级别指定某个类 也可以步制定类 直接在level: 后面配置
第二种日志的配置方式:
第一步:注释道application.yml中关于日志的配置
第二步:新建logback-spring.xml 日志配置文件
<?xml version="1.0" encoding="UTF-8" ?> <configuration> <!-- 控制台的显示 --> <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern> %d - %msg%n </pattern> </layout> </appender> <!-- 日志文件:fileInfoLog --> <appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- 根据范围来过滤 --> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>DENY</onMatch> <!-- 禁止 --> <onMismatch>ACCEPT</onMismatch> <!-- 接受 --> </filter> <!--滚动--> <encoder> <pattern> %msg%n </pattern> </encoder> <!--滚动策略--> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!--路径--> <fileNamePattern>/Users/liuxiaoming/Documents/ideawork/sell_log/info.%d.log</fileNamePattern> </rollingPolicy> </appender> <!-- 日志文件:fileErrorLog --> <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- 根据范围来过滤 --> <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>/Users/liuxiaoming/Documents/ideawork/sell_log/error.%d.log</fileNamePattern> </rollingPolicy> </appender> <!--日志级别--> <root level="info"> <appender-ref ref="consoleLog" /> <appender-ref ref="fileInfoLog" /> <appender-ref ref="fileErrorLog" /> </root> </configuration>
第三步:启动项目 查看生成了两个配置文件
