logback配置、指定類日志輸出到指定文件夾

1、controller代碼demo

package com.duke.api;

@Controller

public class demo {
private static final Logger logger = LoggerFactory.getLogger(demo.class);

     @RequestMapping("/test")

    public void testDemo(HttpServletRequest request, HttpServletResponse resp){
        String string = request.getParameter("demo");

        logger.info(string);

    }

}

2、logback.xml

指定demo類中的日志信息輸出到自定義文件夾中（/home/server/logs/）

<!--  定義日志存儲的地址 -->

<property name="log_address" value="/home/server/logs" />

<!-- log info start -->
<appender name="demo-info" class="ch.qos.logback.core.rolling.RollingFileAppender">
 <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
 <FileNamePattern>${log_address}/demo-info(自定義日志存儲的文件夾)/demo(文件名).%d{yyyy-MM-dd}.log
 </FileNamePattern>

 </rollingPolicy>

          <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
 <layout class="ch.qos.logback.classic.PatternLayout">
 <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
 </layout>
 </encoder>
 <!--日志文件最大的大小 -->
 <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
 <MaxFileSize>10MB</MaxFileSize>
 </triggeringPolicy>
</appender>

<logger name="com.duke.api.Demo" level="DEBUG">
 <appender-ref ref="demo-info" />

</logger>

這就是指定類輸出日志到指定文件夾的全部配置，當訪問該類的時候

會在服務器/home/server/logs/demo-info/下生成一個日志文件

類似demo.2000-01-01.log的文件
