使用idea启动tomcat服务器后，在浏览器打开tomcat首页显示空白页，并提示以下三个错误信息，求解？用tomcat.exe启动tomcat服务器则没有任何问题。
[localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Deploying web application directory [C:\apache-tomcat-8.5.23\webapps\manager]
[localhost-startStop-1] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs.Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
[localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Deployment of web application directory [C:\apache-tomcat-8.5.23\webapps\manager] has finished in [1,112] ms
你这个不是错误，是tomcat的启动日志，代表启动成功了。
楼上说的对，启动成功了。
