+    <!--TimeBasedRollingPolicy:最常用的滚动策略，它根据时间来制定滚动策略，既负责滚动也负责出发滚动-->
+    <!--fileNamePattern:必要节点，包含文件名及“%d”转换符，“%d”可以包含一个java.text.SimpleDateFormat指定的时间格式，如：%d{yyyy-MM}。
+如果直接使用 %d，默认格式是 yyyy-MM-dd。RollingFileAppender的file字节点可有可无，通过设置file，可以为活动文件和归档文件指定不同位置，当前日志总是记录到file指定的文件（活动文件），活动文件的名字不会改变；
+如果没设置file，活动文件的名字会根据fileNamePattern 的值，每隔一段时间改变一次。“/”或者“\”会被当做目录分隔符。 -->
+    <!--maxHistory:可选节点，控制保留的归档文件的最大数量，超出数量就删除旧文件。假设设置每个月滚动，且<maxHistory>是6，则只保存最近6个月的文件，删除之前的旧文件。注意，删除旧文件是，那些为了归档而创建的目录也会被删除。-->
+    <!--SizeBasedTriggeringPolicy:查看当前活动文件的大小，如果超过指定大小会告知RollingFileAppender 触发当前活动文件滚动,只有一个节点：maxFileSize：这是活动文件的大小，默认值是10MB。-->
+    <!--prudent:当为true时，不支持FixedWindowRollingPolicy。支持TimeBasedRollingPolicy，但是有两个限制，1不支持也不允许文件压缩，2不能设置file属性，必须留空。 -->
+    <!--triggeringPolicy:告知 RollingFileAppender 合适激活滚动-->
+    <!--FixedWindowRollingPolicy:根据固定窗口算法重命名文件的滚动策略-->
+    <!--有以下子节点：
+　　　　　　　　<minIndex>:窗口索引最小值
+　　　　　　　　<maxIndex>:窗口索引最大值，当用户指定的窗口过大时，会自动将窗口设置为12。
+　　　　　　　　<fileNamePattern>:必须包含“%i”例如，假设最小值和最大值分别为1和2，命名模式为 mylog%i.log,会产生归档文件mylog1.log和mylog2.log。还可以指定文件压缩选项，例如，mylog%i.log.gz 或者 没有log%i.log.zip-->
+    <!--encoder：对记录事件进行格式化。负责两件事，一是把日志信息转换成字节数组，二是把字节数组写入到输出流。-->
+    <!--PatternLayoutEncoder 是唯一有用的且默认的encoder ，有一个<pattern>节点，用来设置日志的输入格式。使用“%”加“转换符”方式，如果要输出“%”，则必须用“\”对“\%”进行转义。-->
+    <!--SocketAppender、SMTPAppender、DBAppender、SyslogAppender、SiftingAppender不常用-->
+    <!--logger:用来设置某一个包或具体的某一个类的日志打印级别、以及指定<appender>,仅有一个name属性，一个可选的level和一个可选的additivity属性-->
+    <!--可以包含零个或多个<appender-ref>元素，标识这个appender将会添加到这个logger-->
+    <!--属性name: 用来指定受此logger约束的某一个包或者具体的某一个类。-->
+    <!--属性level: 用来设置打印级别，大小写无关：TRACE, DEBUG, INFO, WARN, ERROR, ALL和OFF，还有一个特俗值INHERITED或者同义词NULL，代表强制执行上级的级别。 如果未设置此属性，那么当前logger将会继承上级的级别。-->
+    <!--属性additivity: 是否向上级logger传递打印信息。默认是true。同<logger>一样，可以包含零个或多个<appender-ref>元素，标识这个appender将会添加到这个logger。-->
+    <!--root:它也是<logger>元素，但是它是根logger,是所有<logger>的上级。只有一个level属性，因为name已经被命名为"root",且已经是最上级了。-->
