Question

我按照说明做了一切，安装了所有环境变量，但它仍然无法启动。当我尝试启动时，这是cmd中的输出：

C:\WINDOWS\system32>%CATALINA_HOME%\bin\startup.bat
Using CATALINA_BASE:   "D:\Tomcat"
Using CATALINA_HOME:   "D:\Tomcat"
Using CATALINA_TMPDIR: "D:\Tomcat\temp"
Using JRE_HOME:        "C:\Program Files\Java\jre1.8.0_131"
Using CLASSPATH:       "D:\Tomcat\bin\bootstrap.jar;D:\Tomcat\bin\tomcat-juli.jar"
C:\WINDOWS\system32>

为蝙蝠打开一个窗口并立即消失。 http://127.0.0.1:8080/上没有任何内容。可能是什么问题呢？ startup.bat的内容：

这很可能是一个重复的问题，但我在快速查找中找到的其他答案都没有包含如何找出自己的根本原因的基本技术，因此我在这里回答：

当startup.bat启动的命令行立即消失时，只需使用catalina.bat run，它将在您当前运行的同一命令行中启动tomcat（当然，这仅适用于命令行），你不能再双击了）。否则将在（立即消失的）新打开的命令行窗口中显示的错误消息将在您当前的命令行中保持可见。

最有可能的是，logs/catalina.out中也会找到相同的内容，您也应该检查该文件。

Tomcat无法启动。我哪里错了？
