Spring-Boot預設集成了backlog日誌框架，無需在載入額外的jar包。

只需要在application.properties檔案中新增配置即可(非預設bocklog.xml方式)：

#backlog setting
logging.config=logback.xml  

logback.xml內容如下：

<?xml version="1.0" encoding="UTF-8" ?>
<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <!-- 控制檯設定 -->
 

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- encoder 預設配置為PatternLayoutEncoder -->
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
            </pattern>
        </encoder>
    </appender
 
>


    <!-- * 萬用字元 設定log列印級別 對所有類有效TRACE, DEBUG, INFO, WARN, ERROR, ALL 和 OFF-->
    <root level="DEBUG">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>  

當前僅當只是配置控制檯輸出方式，需要配置File，已經File策略的請觀看博主的該文章介紹。

測試類：

@Controller
@RequestMapping(“test”)
public class TestController {
public static Logger logger = LoggerFactory.getLogger(TestController.class);
@RequestMapping(“”)
public void test() {
logger.debug(“test”);
System.out.println(“呼叫了Test”);
}
}

關於Spring-Boot給出的配置方式如下：

# LOGGING
logging.config= # Location of the logging configuration file. For instance `classpath:logback.xml` for Logback

logging.exception-conversion-word=%wEx # Conversion word used when logging exceptions.

logging.file= # Log file name. For instance `myapp.log`

logging.level.*= # Log levels severity mapping. For instance `logging.level.org.springframework=DEBUG`

logging.path= # Location of the log file. For instance `/var/log`

logging.pattern.console= # Appender pattern for output to the console. Only supported with the default logback setup.

logging.pattern.file= # Appender pattern for output to the file. Only supported with the default logback setup.

logging.pattern.level= # Appender pattern for log level (default %5p). Only supported with the default logback setup.

logging.register-shutdown-hook=false # Register a shutdown hook for the logging system when it is initialized.

有興趣的同學可以去研究下！

PS:最近做一個專案，發現打包成war部署到伺服器上面的時候整合的logback日誌打印不出來。原因logging.config指定的路徑檔案一直識別出來講backlog.xml改名為logback-spring.xml放在resources下面即可。
