例子程式：

package org.sample.logback;

import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.core.util.StatusPrinter;
import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class LogbackTest {

    @Test
    public void testLogback() {
        Logger logger = LoggerFactory.getLogger(LogbackTest.class);
        logger.debug(logger.getName()); // 這個logger（記錄器）名字叫org.sample.logback.LogbackTest
        logger.debug("Hello world."); // 一個級別為DEBUG的logging（記錄）語句，並帶有訊息“Hello world”。
        // 不論專案大小，logging語句並不會有什麼改變（總是像上面那樣簡單），只是配置不同！

        /*
        logback的預設配置策略：當未找到預設配置檔案時，
        logback將把ConsoleAppender新增到root logger（根記錄器）.
        PS. appender是一種可以被視為“輸出目的地”的類。所以上
        面這句話言下之意即：console將被作為root logger的輸出目
        的地之一。
         */

        // 列印logback的內部狀態，這依賴於具體的logback類，而不是slf4j API
        // 當然，在出現errors時，logback會自動列印內部狀態而無需開啟
        LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
        StatusPrinter.print(lc); // 啟用“列印logback內部狀態”的模式，並不是只打印一次。這在診斷logback相關問題的時候非常有用！
    }
}
