springboot的log4j配置与logback配置

log4j配置的依赖

<!-- 删除pom.xml文件中所有对日志jar包的引用-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>log4j-over-slf4j</artifactId>
        </dependency>
<!--排除spring boot对[spring-boot-starter-logging]的依赖，并增加依赖包[spring-boot-starter-log4j.jar]-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-log4j</artifactId>
        </dependency>

log4j.properties的配置：

log4j.rootLogger=info,ServerDailyRollingFile,stdout

log4j.appender.ServerDailyRollingFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ServerDailyRollingFile.DatePattern='.'yyyy-MM-dd
log4j.appender.ServerDailyRollingFile.File=D://test/test.log
log4j.appender.ServerDailyRollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.ServerDailyRollingFile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p [%c] - %m%n
log4j.appender.ServerDailyRollingFile.Append=true

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d yyyy-MM-dd HH:mm:ss %p [%c] %m%n

2：logback 的配置：

properties文件：

logging.config=classpath:logback-spring.xml

 第一种：springboot的logback的默认配置base.xml

logback-spring.xml：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include
        resource="org/springframework/boot/logging/logback/base.xml" />                 //引入springboot默认的日志配置

  
    <!-- 将日志写入数据库 -->
    <appender name="DB"
        class="ch.qos.logback.classic.db.DBAppender">
        <connectionSource
            class="ch.qos.logback.core.db.DataSourceConnectionSource">
            <dataSource
                class="com.mchange.v2.c3p0.ComboPooledDataSource">
                <driverClass>oracle.jdbc.driver.OracleDriver</driverClass>
                <jdbcUrl>jdbc:oracle:thin:@192.168.8.4:1521/orcl</jdbcUrl>
                <user>admin</user>
                <password>123456</password>
            </dataSource>
        </connectionSource>
    </appender>

    <appender name="ASYNC_ROLLING_DB" class="ch.qos.logback.classic.AsyncAppender">
        <appender-ref ref="DB"/>
    </appender>

    <root level="INFO">
        <appender-ref ref="ASYNC_ROLLING_DB"/>


    </root>
 </configuration>

第二种：依赖+配置

<properties>
   <java.version>1.8</java.version>
   <docker.image.prefix>demo</docker.image.prefix>
   <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
   <!-- logback用来设置版本号 -->
   <slf4j.version>1.7.25</slf4j.version>
   <logback.version>1.2.3</logback.version>
</properties>

<!-- logback用到的jar包  -->
        <!-- logback start -->
        <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>
        <!-- logback end -->

 

logback-spring.xml

加打印到控制台，的以及<appender-ref ref="STDOUT"/>

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <--<include
        resource="org/springframework/boot/logging/logback/base.xml" />  -->               //引入springboot默认的日志配置

    <!--打印到控制台 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
     <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
             <pattern>
                %date{yyyy-MM-dd HH:mm:ss.SSS} %-5level[%thread]%logger{56}.%method:%L -%msg%n
            </pattern>
        </encoder>
         
    </appender>  

    <!-- 将日志写入数据库 -->
    <appender name="DB"
        class="ch.qos.logback.classic.db.DBAppender">
        <connectionSource
            class="ch.qos.logback.core.db.DataSourceConnectionSource">
            <dataSource
                class="com.mchange.v2.c3p0.ComboPooledDataSource">
                <driverClass>oracle.jdbc.driver.OracleDriver</driverClass>
                <jdbcUrl>jdbc:oracle:thin:@192.168.8.4:1521/orcl</jdbcUrl>
                <user>admin</user>
                <password>123456</password>
            </dataSource>
        </connectionSource>
    </appender>

    <appender name="ASYNC_ROLLING_DB" class="ch.qos.logback.classic.AsyncAppender">
        <appender-ref ref="DB"/>
    </appender>

    <root level="INFO">
        <appender-ref ref="ASYNC_ROLLING_DB"/>

       <appender-ref ref="STDOUT"/>  

    </root>
 </configuration>
