背景
需要做到以下几步：
- 搭建spring boot ,
- 使用spring boot
- 打包spring boot
开始
下载spring boot demo ,链接在
https://start.spring.io/
一个可用的例子
https://start.spring.io/#!type=maven-project&language=java&platformVersion=3.0.0&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo解压
然后下载下来名字叫demo.zip, 然后需要解压
unzip demo.zip 安装maven
maven 是java的一个包管理工具
对于ubuntu 来说 ，使用下面的命令安装maven
sudo apt install maven添加tomcat
pom.xml 添加tomcat相关内容
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>编译成一个fatjar
使用命令 mvn spring-boot:repackage 编译成一个fat-jar
mvn package启动jar包
命令为java -jar ./target/demo-0.0.1-SNAPSHOT.jar
$ java -jar ./target/demo-0.0.1-SNAPSHOT.jar
