免配置环境变量使用Tomcat+设置项目主页路径为http://localhost:8080+修改tomcat端口号

一、免配置jdk JAVA_HOME和tomcat  CATALINA_HOME环境变量使用tomcat

　　众说周知，使用tomcat需要有java环境，一般情况下需要配置jdk和tomcat的路径到windows系统的环境变量中。但是也可以不用配置环境变量，直接编辑tomcat的startup.bat文件即可，下面是TOMCAT安装路径bin目录下的startup.bat中的代码，红色字体就是配置了。

set JAVA_HOME=E:\Program Files\Java\jdk1.8.0_131

rem Guess CATALINA_HOME if not defined
set "CURRENT_DIR=%cd%"

cd ..
set "CATALINA_HOME=%cd%"
cd "%CURRENT_DIR%"
:gotHome
if exist "%CATALINA_HOME%\bin\catalina.bat" goto okHome
echo The CATALINA_HOME environment variable is not defined correctly
echo This environment variable is needed to run this program
goto end
:okHome

set "EXECUTABLE=%CATALINA_HOME%\bin\catalina.bat"

rem Check that target executable exists
if exist "%EXECUTABLE%" goto okExec
echo Cannot find "%EXECUTABLE%"
echo This file is needed to run this program
goto end
:okExec

rem Get remaining unshifted command line arguments and save them in the
set CMD_LINE_ARGS=
:setArgs
if ""%1""=="""" goto doneSetArgs
set CMD_LINE_ARGS=%CMD_LINE_ARGS% %1
shift
goto setArgs
:doneSetArgs

call "%EXECUTABLE%" start %CMD_LINE_ARGS%

:end
pause

二、设置项目主页路径为http://localhost:8080、修改tomcat端口号

　　tomcat文件夹下的conf文件夹下有个server.xml,port后面的数字就是端口号，修改就好了（有三个），如果只是修改访问端口（如：http：//localhost:8080）,只需要修改第二个就可以了。

　　通过添加<Context path="" docBase="E:\Program Files\apache-tomcat-8.0.37\webapps\fire360-3.0" debug="0" reloadable = "true" />这一行，来修改tomcat的主页路径为项目的主页。

<?xml version=‘1.0‘ encoding=‘utf-8‘?>
