springboot 引入logback框架

1、引入jar包

<slf4j.version>1.7.30</slf4j.version>
<logback.version>1.2.3</logback.version>

　　　　　<!-- log4j -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>${logback.version}</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>${logback.version}</version>
        </dependency>

　　

2、引入logback.xml

<?xml version="1.0" encoding="utf-8"?>
<configuration>

    <property name="log_home" value="./" />
    <!-- 服务名称，自行修改成各自的服务名称 -->
    <property name="app.name" value="test-server" />

    <!-- sql -->
    <appender name="FILE-JDBC" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>${log_home}/${app.name}_jdbc.log</File>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%-5level] [%-5thread] [%X{request.url}] %logger{20} - %msg%n</pattern>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>warn</level>
        </filter>
        <append>true</append>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${log_home}/${app.name}_jdbc_%d{yyyy-MM-dd}.log</fileNamePattern>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
    </appender>

    <!-- 控制台输出日志，方便本地测试使用 -->
    <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
        </encoder>
    </appender>

    <!-- 默认日志输出文件，每天生成一个，保留最近30天的日志 -->
    <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${log_home}/logs/${app.name}.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>${log_home}/logs/${app.name}-.%d{yyyy-MM-dd}.log</FileNamePattern>
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
        </encoder>
    </appender>

    <!-- 记录数据源日志 -->
    <appender name="log4jdbc" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${log_home}/logs/${app.name}-log4jdbc.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>${log_home}/logs/${app.name}-log4jdbc-%d{yyyyMMdd}.log</FileNamePattern>
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%-5level] [%-5thread] [%X{request.url}] %logger{20} - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="com.huazhu.workermgmtservice" additivity="false" level="info">
        <appender-ref ref="file" />

        <!-- 控制台输出,本地调试时可打开,正式环境注释掉 -->
        <appender-ref ref="stdout" />
    </logger>

    <!--打印SQL-->
    <logger name="java.sql" level="DEBUG">
        <appender-ref ref="log4jdbc" />
    </logger>
    <logger name="java.sql.Connection" level="DEBUG" >
        <appender-ref ref="log4jdbc" />
    </logger>
    <logger name="java.sql.Statement" level="DEBUG" >
        <appender-ref ref="log4jdbc" />
    </logger>
    <logger name="java.sql.PreparedStatement" level="DEBUG" >
        <appender-ref ref="log4jdbc" />
    </logger>

    <!-- 记录sql执行的时间，可以分析耗时的sql语句 -->
    <logger name="jdbc.sqltiming" additivity="false">
        <appender-ref ref="FILE-JDBC" />
        <!--debug 控制输出方法名，appender中filter过滤debug级别以下的日志 -->
        <level value="debug" />
    </logger>

    <root level="info">
        <!-- 控制台输出,本地调试时可打开,正式环境注释掉 -->
        <appender-ref ref="stdout" />
        <appender-ref ref="log4jdbc" />
    </root>

</configuration>

　　

3、使用

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

private final  static Logger logger = 
 LoggerFactory.getLogger(YfLaborInfoServiceImpl.class);

logger.info("selectListByCardProjectId info yfLaborInfoDto is {},token is {}", yfLaborInfoDto, token);

　　

4、为何使用slf4j和logback
