docker部署spring boot，安装jdk17、maven3.8.8详细步骤
安装JDK和Maven
在Docker中部署Spring Boot项目需要先安装JDK和Maven。以下是详细步骤：
1.1 安装 JDK 和 Maven
# 安装 JDK 17（推荐版本）
sudo yum install -y java-17-openjdk-devel# 安装 Maven
sudo yum install -y maven
1.2 验证安装
java -version
# 预期输出：openjdk version "17.0.x"mvn -v
# 预期输出：Apache Maven 3.8.x
1.3 升级jdk到17、升级maven3.8.8
1.3.1 jdk
# 卸载 OpenJDK 8
sudo yum remove -y java-1.8.0-openjdk*# 卸载旧版 Maven
sudo yum remove -y maven# 添加 Red Hat 官方仓库（CentOS 7）
sudo yum install -y https://cdn.azul.com/zulu/bin/zulu-repo-1.0.0-1.noarch.rpm# 安装 Zulu JDK 17（Azure 认证版本）
sudo yum install -y zulu17-jdk# 验证安装
java -version
# 预期输出：openjdk version "17.0.12" 2024-07-16 LTS1.3.2 maven
# 下载 Maven 3.8.8
wget https://archive.apache.org/dist/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz# 如果上述链接失效，可直接使用阿里云镜像
wget https://mirrors.cloud.tencent.com/apache/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz# 确保目标目录存在
sudo mkdir -p /opt# 解压文件（注意文件名需与下载的包名一致）
sudo tar -xzf apache-maven-3.8.8-bin.tar.gz -C /opt/# 编辑环境变量文件
echo 'export MAVEN_HOME=/opt/apache-maven-3.8.8' | sudo tee -a /etc/profile
echo 'export PATH=$MAVEN_HOME/bin:$PATH' | sudo tee -a /etc/profile# 使配置生效
source /etc/profilemvn -v
# 预期输出：
# Apache Maven 3.8.8 (...)
# Maven home: /opt/apache-maven-3.8.8
构建 Spring Boot 项目

# 在项目根目录执行
mvn clean package
编写 Dockerfile
3.1 在项目根目录创建 Dockerfile
# 使用 Eclipse Temurin JDK 17 作为基础镜像
FROM eclipse-temurin:17-jre# 设置工作目录
WORKDIR /app# 将 JAR 文件复制到容器中
COPY wendaoplatform-0.0.1-SNAPSHOT.jar /app/app.jar# 暴露应用程序端口（根据您的应用需要修改）
EXPOSE 1122# 设置容器启动时执行的命令
ENTRYPOINT ["java", "-jar", "app.jar"]
构建 Docker 镜像
# 在项目根目录执行
docker build -t spring-boot-app:latest .
运行 Docker 容器
# 如果之前创建了 wdzm_network，加入该网络
docker run -p 8080:8080 \--network wdzm_network \--name spring-boot-app \-v /root/spring-boot-app/logs:/app/logs \-e SPRING_PROFILES_ACTIVE=prod \-d spring-boot-app:latest
配置 Nginx 反向代理
server {listen 80;server_name 192.168.0.64;# 前端静态文件（已部署的 Vue 项目）root /usr/share/nginx/html/dist;index index.html;location / {try_files $uri $uri/ /index.html;}# 代理 Spring Boot APIlocation /api/ {proxy_pass http://spring-boot-app:8080/; # 使用容器名称proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;}
}
重新加载 Nginx
docker restart nginx
检查容器状态
docker ps | grep spring-boot-app
# 预期输出：0.0.0.0:8080->8080/tcp
