Gitee：a7. (JiaBin1) - Gitee.com

1、安装Docker

#1.需要的安装包
yum install -y yum-utils

#2.设置镜像的仓库
yum-config-manager \
	--add-repo \
	http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo		#使用阿里云仓库
	
#更新yum软件包索引
yum makecache fast

#3.安装docker相关的内容
yum install docker-ce docker-ce-cli containerd.io

#4.启动docker
systemctl start docker

#5.查看当前docker版本
docker version

2、安装Docker-Compose

#1、下载
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 这个可能快点！
curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.5/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

#2、授权
sudo chmod +x /usr/local/bin/docker-compose

3、部署SpringBoot + MySQL

1、创建SpringBoot项目，导入以下依赖

• <dependencies>
      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>
      </dependency>
  
      <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-test</artifactId>
          <scope>test</scope>
      </dependency>
  
      <dependency>
          <groupId>org.mybatis.spring.boot</groupId>
          <artifactId>mybatis-spring-boot-starter</artifactId>
          <version>2.2.2</version>
      </dependency>
  
      <dependency>
          <groupId>com.alibaba</groupId>
          <artifactId>fastjson</artifactId>
          <version>1.2.76</version>
      </dependency>
  
      <dependency>
          <groupId>mysql</groupId>
          <artifactId>mysql-connector-java</artifactId>
          <version>5.1.48</version>
      </dependency>
  
      <dependency>
          <groupId>org.projectlombok</groupId>
          <artifactId>lombok</artifactId>
      </dependency>
  </dependencies>

2、搭建基础环境架构

【实体类】

• /**
   * @Author 嘉宾
   * @Data 2022/3/21 14:54
   * @Version 1.0
   */
  @Data
  @AllArgsConstructor
  @NoArgsConstructor
  public class Person {
      private Integer pid;
      private String pname;
      private Integer psex;
  }

【接口】

• /**
   * @Author 嘉宾
   * @Data 2022/3/21 14:55
   * @Version 1.0
   */
  @Mapper
  public interface PersonMapper {
      /**
       * 查询全部信息
        */
      List<Person> findAll();
  }

【mapper映射】

• <?xml version="1.0" encoding="UTF-8" ?>
  <!DOCTYPE mapper
          PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
          "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
  <mapper namespace="com.jiabin.mapper.PersonMapper">
  
      <!--查询全部信息-->
      <select id="findAll" resultType="Person">
          select * from person
      </select>
  
  </mapper>

【service】

• /**
   * @Author 嘉宾
   * @Data 2022/3/21 14:57
   * @Version 1.0
   */
  public interface PersonService {
      /**
       * 查询全部信息
       */
      List<Person> findAll();
  }

【impl】

• /**
   * @Author 嘉宾
   * @Data 2022/3/21 14:57
   * @Version 1.0
   */
  @Service
  public class PersonServiceImpl implements PersonService {
  
      @Autowired
      private PersonMapper personMapper;
  
      @Override
      public List<Person> findAll() {
          return personMapper.findAll();
      }
  }

【controller】

• /**
   * @Author 嘉宾
   * @Data 2022/3/21 14:58
   * @Version 1.0
   */
  @RestController
  @RequestMapping("/person")
  public class PersonController {
  
      @Autowired
      private PersonService personService;
  
      @GetMapping("/findAll")
      public String findAll(){
          List<Person> personList = personService.findAll();
          return personList.toString();
      }
  
      @GetMapping("/hello")
      public String hello(){
          return "<h1 color='red'>Hello.JiaBin!</hello>";
      }
  }

【配置文件】

• spring.datasource.driver-class-name=com.mysql.jdbc.Driver
  #这里填写服务名即可mysqldbserver，无需端口号
  spring.datasource.url=jdbc:mysql://mysqldbserver:3306/sys?useUnicode=true&characterEncoding=utf-8&useSSL=false
  spring.datasource.username=root
  spring.datasource.password=123456
  
  mybatis.mapper-locations=classpath:mapper/*.xml
  mybatis.type-aliases-package=com.jiabin.pojo

3、Dockerfile1

• FROM java:8
  
  VOLUME /vol/development
  
  RUN mkdir -p /vol/development
  
  WORKDIR /vol/development
  
  COPY 这里需要改为自己的jar包.jar /vol/development/app.jar
  
  CMD ["java", "-Xmx200m", "-Djava.security.egd=file:/dev/./urandom","-jar","/vol/development/app.jar"]

4、Dockerfile

• FROM mysql:5.7.17

5、docker-compose.yml

• version : '3'
  services:
    #sql服务
    mysqldbserver:
    	#服务名称
      container_name: mysqldbserver
      #镜像
      image: mysql:5.7.17
      build:
        context: .
        dockerfile: Dockerfile
      #端口
      ports:
        - "3306:3306"
      command: [	#执行多条指令
          'mysqld',
          '--innodb-buffer-pool-size=20M',
          '--character-set-server=utf8',
          '--collation-server=utf8_general_ci',
          '--default-time-zone=+8:00',
          '--lower-case-table-names=1'
      ]
      environment:
        # 数据库
        MYSQL_DATABASE: sys
        # 设置root用户密码
        MYSQL_ROOT_PASSWORD: 123456
    #spring服务
    springappserver:
    	# 服务名称
      container_name: springappserver
      build:
        context: .
        dockerfile: Dockerfile1
      ports:	#端口
        - "8080:8080"
      volumes:	#数据卷
        - /vol/development
      depends_on:
        - mysqldbserver
      links:	#连接sql
        - mysqldbserver

6、将项目打包以及上述三个配置文件统一上传到我们的服务器

• 
• 

7、使用命令docker-compose up部署，通过ip+端口号访问项目即可！
