Java Web Learning-environment building and Java Web getting started

Java Web Learning-environment building and Java Web getting started

Recently, I want to learn about JavaWeb. When setting up an environment, I found that there are many tutorials on the Internet, but I still need to find them one by one when I build my own environment. So I want to write down the appropriate environment.

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 jdk configuration is added, 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. Configure maven Environment Variables

(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 start D: \ apache-tomcat-8.0.42-windows-x86 \ apache-tomcat-8.0.42 \ bin startup command (if the installation path is not the same, find their corresponding location)

Do not close this window and enter http: // localhost: 8080/in the browser/

(3) Input mvn-v in cmd

If an error is reported, the jdk version is too low or does not match. You can change the value of the Java_Home variable to a later JDK version.
