ps:使用tomcat插件，刷新maven後，可以看到tomcat7：

點擊展開：雙擊tomcat7:run，啓動項目

這時候控制檯會出現如下內容，並且項目啓動成功，卻MySimpleJob 類中的方法並無日誌打印：

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

在resources文件夾下，創建log4j.properties文件：

log4j.rootLogger=info, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

然後，再次重啓tomcat，控制檯打印：
