linux下配置JavaWeb开发环境+vscode配置

首先从官方网站下载maven,jdk和tomcat

Jdk,Maven和tomcat环境变量配置

通过之前的一篇文章，开发环境下可以直接讲路径写入/etc/profile，执行以下指令即可

echo '#set Java environment'>>/etc/profile

echo 'export JAVA_HOME=/root/jdk1.8.0_241'>>/etc/profile # 将java的目录改为自己系统上java的目录

echo 'export PATH=$JAVA_HOME/bin:$PATH'>>/etc/profile

echo 'export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar'>>/etc/profile

echo '#set Tomcat environment'>>/etc/profile

echo 'export CATALINA_HOME=/root/apache-tomcat-8.5.53'>>/etc/profile # 将tomcat的目录改为自己系统上tomcat的目录

echo 'export PATH=$JAVA_HOME/bin:$CATALINA_HOME/bin:$PATH'>>/etc/profile

echo 'export CLASSPATH=.:$JAVA_HOME/lib:$CATALINA_HOME/lib'>>/etc/profile

echo '#set Maven environment'>>/etc/profile
