1、JDK-环境配置：
JAVA_HOME=D:\Program Files\Java\jdk1.7.0_45
CLASSPATH=.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar
Path=%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;
2、免安装版TOMCAT：
TOMCAT1-环境配置
CATALINA_BASE=D:\Program Files\apache-tomcat-7.0.47
CATALINA_HOME=D:\Program Files\apache-tomcat-7.0.47
Path=%CATALINA_HOME%\lib;%CATALINA_HOME%\bin;
conf下server.xml
Server port=8006 shutdown="SHUTDOWN"；
Connector port=80 protocol="HTTP/1.1"；
Connector port=8009 protocol="AJP/1.3"
TOMCAT2-环境配置
CATALINA_BASE_7M=D:\Program Files\apache-tomcat-7.0.47-8080
CATALINA_HOME_7M=D:\Program Files\apache-tomcat-7.0.47-8080
Path=%CATALINA_HOME_7M%\lib;%CATALINA_HOME_7M%\bin;
bin下catalina.bat、service.bat、shutdown.bat、startup.bat中“CATALINA_BASE”改为“CATALINA_BASE_7M”，“CATALINA_HOME”改为“CATALINA_HOME_7M”
conf下server.xml
Server port=8086 shutdown="SHUTDOWN"；
Connector port=8080 protocol="HTTP/1.1"；
Connector port=8089 protocol="AJP/1.3"
3、不依赖环境变量中，指定jdk：找到bin下的setclasspath.bat文件；在文件的开始出添加如下代码：
set JAVA_HOME=D:\Program Files\Java\jdk1.8.0_60
set JRE_HOME=D:\Program Files\Java\jre1.8.0_60
