原因：没有加工厂创建方法，即注解标注@PluginFactory的这个方法，必须提供
完整代码如下：

配置文件

Configuration:
  status: warn
  packages: com.***.**.*.log4j
  monitorInterval: 30
  strict: true
  Appenders:
    Console:  #输出到控制台
      name: CONSOLE
      target: SYSTEM_OUT
      filters:
        ScheduleLoggerFilter:
          level: info
          onMatch: ACCEPT
          onMismatch: DENY

注意：

• Console这个appender下的只有第一个filter会生效
• 需要配置扫描路径Configuration.packages，不然扫描不到配置类
