-     * 初始化与配置Logger   Log4j
-     * 日志信息格式中符号所代表的含义
-     * （1）－X号: X信息输出时左对齐。
-     * （2）%p: 输出日志信息优先级，即DEBUG，INFO，WARN，ERROR，FATAL。
-     * （3）%d: 输出日志时间点的日期或时间，默认格式为ISO8601，也可以在其后指定格式，比如：%d{yyy MMM dd HH:mm:ss,SSS}，输出类似：2002年10月18日 22：10：28，921。
-     * （4）%r: 输出自应用启动到输出该log信息耗费的毫秒数。
-     * （5）%c: 输出日志信息所属的类目，通常就是所在类的全名。
-     * （6）%t: 输出产生该日志事件的线程名。
-     * （7）%l: 输出日志事件的发生位置，相当于%C.%M(%F:%L)的组合,包括类目名、发生的线程，以及在代码中的行数。举例：Testlog4.main(TestLog4.java:10)。
-     * （8）%x: 输出和当前线程相关联的NDC(嵌套诊断环境),尤其用到像java servlets这样的多客户多线程的应用中。
-     * （9）%%: 输出一个"%"字符。
-     * （10）%F: 输出日志消息产生时所在的文件名称。
-     * （11）%L: 输出代码中的行号。
-     * （12）%m: 输出代码中指定的消息,产生的日志具体信息。
-     * （13）%n: 输出一个回车换行符，Windows平台为"\r\n"，Unix平台为"\n"输出日志信息换行。
-     * 可以在%与模式字符之间加上修饰符来控制其最小宽度、最大宽度、和文本的对齐方式。如：
-     * (1)%20c：指定输出category的名称，最小的宽度是20，如果category的名称小于20的话，默认的情况下右对齐。
-     * (2)%-20c:指定输出category的名称，最小的宽度是20，如果category的名称小于20的话，"-"号指定左对齐。
-     * (3)%.30c:指定输出category的名称，最大的宽度是30，如果category的名称大于30的话，就会将左边多出的字符截掉，但小于30的话也不会有空格。
-     * (4)%20.30c:如果category的名称小于20就补空格，并且右对齐，如果其名称长于30字符，就从左边交远销出的字符截掉。
