JavaWeb environment construction

I want to learn JavaWeb recently. When I was setting up the environment, I found that there are many tutorials on the Internet, but when I build it myself, I still have to look for them one by one. So I want to write down an environment setup that suits me.

1. Jdk environment configuration

(1) Environment variable name: JAVA_HOME

Variable value: D:\Program Files (x86)\Java\jdk1.8.0_121 ( JDK installation path)

(2) Environment variable name: CLASSPATH

Variable value:;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\ tools.jar;

(3) Environment variable name: PATH

Variable value:;%JAVA_HOME%\bin;%JAVA_HOME%\ jre\bin;

2. Tomcat environment configuration

(1) Environment variable name: CATALINA_HOME

Variable value: D:\apache-tomcat-8.0.42-windows -x86\apache-tomcat-8.0.42

(2) Environment variable name: Tomcat_HOME

Variable value: D:\apache-tomcat-8.0.42-windows-x86\apache- tomcat-8.0.42

(3) Environment variable name: CALSSPATH

Variable value:;%CATALINA_HOME%\lib\servlet-api.jar;(If you add jdk configuration, the value of this variable should be:;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\lib\servlet-api.jar;)

(4) Environment variable name: PATH

Variable value:;%CATALINA_HOME%\lib\servlet-api.jar; (This step may be a bit redundant)

3. Maven environment variable configuration

(1) Environment variable name: maven_home

Variable value: D:\apache-maven-3.3 .9-bin\apache-maven-3.3.9

(2) Environment variable name: PATH

Variable value:;%maven_home %\bin;

4. Configuration verification

(1) Enter javac or Java -version

in the jdk cmd console

(2) Tomcat starts the startup command under D:\apache-tomcat-8.0.42-windows-x86\apache-tomcat-8.0.42\bin (if the installation path is different, find your own corresponding one) Location)

## 不 Do not close this window in the browser to enter http: // localhost: 8080/

# ( 3) Maven enter mvn -v

in cmd                                                                                                                                                     -                                                            You can change the value of the Java_Home variable to point to a higher version of JDK
