⛵小结
一、需求说明编写一个SpringBoot + Redis 的微服务项目，并提供 hello接口，每访问一次接口，计数器+1
二、效果图
目录说明
docker-compose.yml ：项目的启动文件，配置编排等
Dockerfile：项目上线所需要的依赖，以及启动方式
四、核心源码 ♻️Java依赖与接口依赖文件

接口
HelloController
package com.wanshi.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @author whc
* @date 2022/6/9 10:06
*/
@RestController
public class HelloController {
@Autowired
private StringRedisTemplate redisTemplate;
@GetMapping("/hello")
public String hello() {
Long views = redisTemplate.opsForValue().increment("views");
return "hello, xiaowang, views:" + views;
}
}
配置文件
application.yml
server:
port: 8080
spring:
redis:
host: redis
♨️Docker相关源码
Dockerfile
FROM java:8
COPY *.jar /app.jar
CMD ["--server.port=8080"]
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "/app.jar"]
docker-compose.yml
version: '3.8'
services:
xiwoangapp:
build: .
image: xiaowangapp
depends_on:
- redis
ports:
- "8080:8080"
redis:
image: "redis:3.0.7"
五、部署项目
打包后端项目通过命令
mvn clean package
jar包与配置文件上传至Linux服务器，新建指定文件夹（通过Filezilla上传文件）
执行命令启动
docker-compose up
部署成功后我们查看服务是否启动
docker ps
本机进行访问
curl localhost:8080/hello
以上就是【Bug 终结者】对 【云原生】Docker Compose 进阶 – 部署微服务项目上线 的简单介绍 ，Compose 部署项目，实战练习，进阶！
