Java Tomcat 8日志文件未显示System.out.Println数据

我在这个虚拟机中安装了ubuntu虚拟机，我安装了Tomcat 8并部署了Java Web应用程序，在这个应用程序中我使用了以下代码

System.out.println（“测试文本”）

但是当我通过
/opt/tomcat/logs/catalina.2016-05-20.log查看我的tomcat日志时
文件中没有像“测试文本”这样的打印。
但是我的应用程序正在成功运行，没有错误

我的
/opt/tomcat/conf/logging.properties

请帮助我解决此问题。
我将尝试java.util.logging；另外，也许我的问题很幼稚，但我必须问：您是否在应用程序的服务器端打印？该文件如何？@Michaël cataline.out文件仅包含以下数据：“/opt/tomcat/bin/catalina.sh:line 401:/usr/java/jdk1.8.0_60/jre/bin/java:没有这样的文件或目录/opt/tomcat/bin/catalina.sh:line 401:/usr/java/jdk1.8.0_60/jre/bin/java:没有这样的文件或目录”@user3441151是否打开了日志文件夹中的所有文件？@Michaël是，但没有包含sysout文本的文件。
