免配置環境變量使用Tomcat+設置項目主頁路徑為http://localhost:8080+修改tomcat端口號

一、免配置jdk JAVA_HOME和tomcat  CATALINA_HOME環境變量使用tomcat

　　眾說周知，使用tomcat需要有java環境，一般情況下需要配置jdk和tomcat的路徑到windows系統的環境變量中。但是也可以不用配置環境變量，直接編輯tomcat的startup.bat文件即可，下面是TOMCAT安裝路徑bin目錄下的startup.bat中的代碼，紅色字體就是配置了。其實這種方法適用於其它程序，例如：MAVEN的配置，maven運行也需要JAVA_HOME，可以在maven的bin目錄下的mvn.cmd中做類似的配置即可。

rem ---------當前bat文件目錄的上級--------
set CATALINA_HOME=%~dp0..

rem -----------setclasspath.bat中要用到JAVA_HOME----------
set JAVA_HOME=E:\Program Files\Java\jdk1.8.0_131


rem Guess CATALINA_HOME if not defined
set "CURRENT_DIR=%cd%"
if not "%CATALINA_HOME%" == "" goto gotHome
set "CATALINA_HOME=%CURRENT_DIR%"
if exist "%CATALINA_HOME%\bin\catalina.bat" goto okHome
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、設置項目主頁路徑為http://localhost:8080、修改tomcat端口號

　　tomcat文件夾下的conf文件夾下有個server.xml,port后面的數字就是端口號，修改就好了（有三個），如果只是修改訪問端口（如：http：//localhost:8080）,只需要修改第二個就可以了。

　　通過添加<Context path="" docBase="E:\Program Files\apache-tomcat-8.0.37\webapps\fire360-3.0" debug="0" reloadable = "true" />這一行，來修改tomcat的主頁路徑為項目的主頁。

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