老板下了死命令，要把日志系统切换到Logback (5)

基于我们对 RollingPolicy 的了解，可以把 logback-test.xml 的内容调整为以下内容：

<configuration>
    <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
        <Target>System.out</Target>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
<appender name="D" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <Append>true</Append>
    <File>debug.log</File>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!--            按天轮转 -->
        <fileNamePattern>debug.%d{yyyy-MM-dd}.log</fileNamePattern>
        <!--            保存 30 天的历史记录，最大大小为 30GB -->
        <maxHistory>30</maxHistory>
        <totalSizeCap>3GB</totalSizeCap>
    </rollingPolicy>
    <encoder>
        <pattern>%relative [%thread] %-5level %logger{35} - %msg%n</pattern>
    </encoder>
</appender>
    <appender name="E" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>error.log</File>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--            按天轮转 -->
            <fileNamePattern>error.%d{yyyy-MM-dd}.log</fileNamePattern>
            <!--            保存 30 天的历史记录，最大大小为 30GB -->
            <maxHistory>30</maxHistory>
            <totalSizeCap>3GB</totalSizeCap>
        </rollingPolicy>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n</pattern>
        </encoder>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
    </appender>
    <root level="debug">
        <appender-ref ref="stdout"/>
        <appender-ref ref="D"/>
        <appender-ref ref="E"/>
    </root>
</configuration>

修改 Test 类的内容：

public class Test {
    static Logger logger = LoggerFactory.getLogger(Test.class);
    public static void main(String[] args) {
        logger.debug("logback");
        logger.error("logback");
    }
}
