JavaWeb-tomcat安装（Unsupported major.minor version 51.0/startup.bat闪退）

JavaWeb-tomcat安装（Unsupported major.minor version 51.0）

一 启动startup.bat 出错i

今天安装tomcat出错，折腾了一下午，收获了许多，特此分享一下，同时也分享一下自己总结的方法

二 寻错方法

和我一样，大多数出现闪退的时候，百度一下大多数结果都是环境错误，我的环境虽然没有错，但也检查了很久，心很累

if "%OS%" == "Windows_NT" setlocal rem --------------------------------------------------------------------------- rem Start script for the CATALINA Server rem ---------------------------------------------------------------------------

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%   //将start改为run

:end

PAUSE    //末尾加上Pause

可以直接看到自己的错误的信息，进而进行处理

三 错误处理

JAVA_HOME 错误：环境变量错误

Unsupported major.minor version 51.0 错误：jdk版本和tomcat中的class文件版本不对应，解决方式jdk1.6对应tomcat6.xx,应该是一一对应
