Java 코드를 사용하여 로그백 구성을 작성하는 방법

public class SecurityLoggerFactory {

    private static final String logPath = "/export/Logs/securityLog/securityLog.log";

     * 设置路径
     * 设置滚动方式
     */

        //loggerContext.reset();

        rollingFileAppender.setContext(loggerContext);
        rollingFileAppender.setAppend(true);
        rollingFileAppender.setName("jdSecurityLogAppender");
        rollingFileAppender.setFile(logPath);

        PatternLayoutEncoder encoder = new PatternLayoutEncoder();
