日志输出到文件

1、需要添加依赖:

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-logging</artifactId>

</dependency>

2、配置文件添加以下内容:application.properties

logging.config= classpath:logback.xml

3、在resource加入文件:logback.xml

<configuration scan="true" scanPeriod="10 seconds">

    <include resource="org/springframework/boot/logging/logback/base.xml" />

    <appender name="INFO_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

                <maxFileSize>500MB</maxFileSize>

            </timeBasedFileNamingAndTriggeringPolicy>

            <maxHistory>2</maxHistory>

        </rollingPolicy>

        <layout class="ch.qos.logback.classic.PatternLayout">

    </appender>

            </timeBasedFileNamingAndTriggeringPolicy>

            <maxHistory>2</maxHistory>

        </rollingPolicy>

        <layout class="ch.qos.logback.classic.PatternLayout">

        </layout>

    </appender>

    <root level="INFO">

        <appender-ref ref="INFO_FILE" />

        <appender-ref ref="ERROR_FILE" />

    </root>

</configuration>
