docker+jib集成springboot+mysql项目

第一步：在 IDE 上快速创建一个 springboot 项目(博主用的是 IDEA)

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- 数据库 ORM 框架 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.10</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        
        <!-- setter/getter 注解 -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>        

项目结构：

 第二步：快速创建一个 UserMsg 的实体类

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import lombok.Getter;
import lombok.Setter;

import javax.persistence.*;
import java.io.Serializable;

/**
 * @author chaoyou
 * @email 
 * @date 2020-8-27 18:51
 * @Description
 * @Reference
 */

@Entity
@Table(name = "user_msg")
@Setter
@Getter
@JsonIgnoreProperties({"handler", "hibernateLazyInitializer"})
public class UserMsg implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @Column
    private String username;
    @Column
    private String password;

    public UserMsg() {
    }

    public UserMsg(String username, String password) {
        this.username = username;
        this.password = password;
    }
}

import lombok.Getter;
import lombok.Setter;

/**
 * @author chaoyou
 * @email 
 * @date 2020-8-27 19:11
 * @Description
 * @Reference
 */
@Setter
@Getter
public class UserMsgForm {
    private String username;
    private String password;
}

第三步：UserMsg 实体类的 dao 层

import com.example.demo.model.UserMsg;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;

import java.io.Serializable;

/**
 * @author chaoyou
 * @email 
 * @date 2020-8-27 18:55
 * @Description
 * @Reference
 */
public interface UserMsgDao extends CrudRepository<UserMsg, Serializable> {
    @Query(value = "select * from user_msg where username = ?1", nativeQuery = true)
    UserMsg getByUsername(String username);

    UserMsg getByUsernameAndPassword(String username, String password);
}

第四步：UserMsg 实体类的 service 层

import com.example.demo.model.UserMsg;

/**
 * @author chaoyou
 * @email 
 * @date 2020-8-27 18:57
 * @Description
 * @Reference
 */
public interface UserMsgService {
    public String save(UserMsg userMsg);
    public Object get(String username);
}

import com.example.demo.dao.UserMsgDao;
import com.example.demo.model.UserMsg;
import com.example.demo.service.UserMsgService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * @author chaoyou
 * @email 
 * @date 2020-8-27 18:58
 * @Description
 * @Reference
 */
@Service
public class UserMsgServiceImpl implements UserMsgService {

    private UserMsgDao dao;
    @Autowired
    public UserMsgServiceImpl(UserMsgDao dao) {
        this.dao = dao;
    }

    @Override
    public String save(UserMsg userMsg) {
        String reuslt = "";
        try {
            UserMsg userMsg1 = dao.getByUsernameAndPassword(userMsg.getUsername(), userMsg.getPassword());
            if (userMsg1 != null){
                return "【username=" + userMsg.getUsername() + ", password=" + userMsg.getPassword() + "】账号信息已经存在！";
            }
            dao.save(new UserMsg(userMsg.getUsername(), userMsg.getPassword()));
            reuslt = "success";
        } catch (Exception e){
            reuslt = "新建账号失败！";
        }
        return reuslt;
    }

    @Override
    public Object get(String username) {
        Object reuslt = "";
        try {
            reuslt = dao.getByUsername(username);
        } catch (Exception e){
            reuslt = "查询账户信息失败！";
        }
        return reuslt;
    }
}

第五步：UserMsg 实体类的 controller 层

import com.example.demo.model.UserMsg;
import com.example.demo.model.form.UserMsgForm;
import com.example.demo.service.UserMsgService;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.util.ObjectUtils;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author chaoyou
 * @email 
 * @date 2020-8-27 19:09
 * @Description
 * @Reference
 */
@RestController
@RequestMapping("/user")
public class UserMsgController {

    @Autowired
    private UserMsgService service;

    @PostMapping(value = "/save", produces = "application/json;charset=utf-8")
    public ResponseEntity save(UserMsgForm userMsgForm){
        String result = "";
        if (ObjectUtils.isEmpty(userMsgForm)){
            result = "账号信息不能为空！";
        } else {
            UserMsg userMsg = new UserMsg();
            BeanUtils.copyProperties(userMsgForm, userMsg, "id");
            result = service.save(userMsg);
        }
        return ResponseEntity.ok(result);
    }

    @GetMapping(value = "/get", produces = "application/json;charset=utf-8")
    public ResponseEntity get(String username){
        Object result = "";
        if (ObjectUtils.isEmpty(username)){
            result = "账号信息不能为空！";
        } else {
            result = service.get(username);
        }
        return ResponseEntity.ok(result);
    }
}

第六步：设置运行环境配置文件

第八步：把项目推送到 Linux 上

 第九步：在 docker 上跑一个 mysql 容器

##搜索 mysql 镜像
——docker search mysql8.0

##拉取 mysql8.0 镜像
——docker pull mysql8.0

##跑 mysql 镜像
——docker run -d -p 3306:3306 --name mysqltest -e MYSQL_ROOT_PASSWORD=123456 docker.io/mysql:8.0

##进入 mysqltest 容器内部
——docker exec -it mysqltest /bin/bash

##查看容器内部ip
——cat /etc/hosts

 第十步：进入项目的配置文件中修改数据库的 ip 地址

#进入application-dev.properties
——cd src/main/resources

#修改 application-dev.properties 信息(把ip换成mysqltest容器的内部ip)
——vi application.properties

第十一步：进入到该项目的 pom.xml 同级目录下

接下来利用 jib 插件对项目进行打包成镜像包(jib-image.tar)，有个前提 Linux 环境有安装 jdk 和 maven(安装参考：https://www.cnblogs.com/chaoyou/p/13572888.html)

#打包命令

[root@localhost demo]# mvn compile jib:buildTar

 打包完成进入 target 目录下就可以看到镜像包( jib-image.tar )

 第十二步：把镜像包( jib-image.tar )推进 docker 镜像库( docker images )

##把镜像包( jib-image.tar )推进 docker 仓库
[root@localhost target]# docker load < jib-image.tar

##把 docker 镜像库中的镜像打包成 tar 镜像包
[root@localhost target]# docker save -o /chaoyou/demo.tar chaoyou/demo:0.0.1-SNAPSHOT

第十三步：跑 chaoyuou/demo 镜像

#跑镜像
——docker run --rm -p 8080:8080 chaoyou/demo:0.0.1-SNAPSHOT
