Ubuntu下部署Spring Boot 2.7开发环境

部署之前

环境：Ubuntu 20.04

过程参考 Spring 官方文档

Spring Boot Reference Documentation

安装依赖

Spring Boot 2.7.0 requires Java 8 and is compatible up to and including Java 18. Spring Framework 5.3.20 or above is also required.

Explicit build support is provided for the following build tools:

Build Tool Version
Maven 3.5+
Gradle 6.8.x, 6.9.x, and 7.x

JDK

选用了Liberica JDK 11

Liberica Package Repositories | BellSoft Java (bell-sw.com)

首先把它的软件源加进来

1
2
wget -q -O - https://download.bell-sw.com/pki/GPG-KEY-bellsoft | sudo apt-key add -
echo "deb [arch=amd64] https://apt.bell-sw.com/ stable main" | sudo tee /etc/apt/sources.list.d/bellsoft.list

然后更新源，安装

1
2
sudo apt-get update
sudo apt-get install bellsoft-java11

修改环境变量

1
2
3
# JDK
export JAVA_HOME=/usr/lib/jvm/bellsoft-java11-amd64/
export PATH=$PATH:$JAVA_HOME/bin

Maven

Spring Boot is compatible with Apache Maven 3.3 or above

参考 Maven 官网的引导进行

通过 wget 下载

1
wget https://dlcdn.apache.org/maven/maven-3/3.8.5/binaries/apache-maven-3.8.5-bin.tar.gz

解压一下

1
tar xzvf apache-maven-3.8.5-bin.tar.gz

添加环境变量

1
2
# Maven
export PATH=$PATH:~/apache-maven-3.8.5/bin

检查是否配置正确

bakaft@BakaFT-PC:~/apache-maven-3.8.5/bin$ mvn -v
Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)
Maven home: /home/bakaft/apache-maven-3.8.5
Java version: 11.0.15, vendor: BellSoft, runtime: /usr/lib/jvm/bellsoft-java11-amd64
Default locale: en, platform encoding: UTF-8
OS name: "linux", version: "5.10.16.3-microsoft-standard-wsl2", arch: "amd64", family: "unix"

(可选)Spring-CLI

官网的文档推荐使用Spring-CLI进行管理

下载

1
2
wget https://repo.spring.io/release/org/springframework/boot/spring-boot-cli/2.7.0/spring-boot-cli-2.7.0-bin.tar.gz
tar xzvf spring-boot-cli-2.7.0-bin.tar.gz

设置环境变量

1
2
3
# Spring-CLI
export SPRING_HOME=~/spring-2.7.0
export PATH=$PATH:$SPRING_HOME/bin

运行一个最小 Spring Boot 实例

新建一个文件app.groovy，写入：

9
@RestController
class ThisWillActuallyRun {

    @RequestMapping("/")
    String home() {
        "Hello World!"
    }

}

使用 Spring-CLI 运行它

可以看到，这样就启动了一个非常小的 Spring Boot 实例

bakaft@BakaFT-PC:~$ curl http://localhost:8080 -w '\n'
Hello World!

创建一个 Spring Boot 项目

Spring Boot 项目本质上还是一个 Maven(或者 Gradle)项目

编写 pom.xml

创建一个新的文件夹，让 Maven 可以来初始化项目

在这个文件夹里创建pom.xml，并写入如下内容，你可以根据需求更改内容：

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

    <artifactId>spring-boot-demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.0</version>
    </parent>
    <dependencies>
    	<dependency>
        	<groupId>org.springframework.boot</groupId>
        	<artifactId>spring-boot-starter-web</artifactId>
    	</dependency>
    </dependencies>

    <!-- Additional lines to be added here... -->

</project>

这个时候，你就可以将你的这个 Maven 项目导入 IDE 进行开发了，不过接下来继续使用命令行进行

接下来更新 Maven 的依赖树，第一次运行会先下载依赖

1
mvn dependency:tree

在运行一次就可以看到当前项目的依赖树了
