2.初始dttask-common工程
dttask-common就是一个普通的java jar应用

2.2 初始化数据库相关类,为mybatis-plus做准备
这里Job类、DttaskJob类、DeviceLink类中使用了对象字段,数据库使用了mysql的json字段格式,使用了FastjsonTypeHandler类,具体代码如下:
@Data
@TableName(value = "t_job", autoResultMap = true)
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class Job extends BaseEntity implements Serializable {
@TableField("device_id")
private Long deviceId;
@TableField("device_link_id")
private Long deviceLinkId;
@TableField("link_type")
private Integer linkType;
@TableField(value = "link_spec", typeHandler = FastjsonTypeHandler.class)
private LinkSpec linkSpec;
@TableField(value = "job_spec", typeHandler = FastjsonTypeHandler.class)
private JobSpec jobSpec;
}
3.初始化dttask-server工程

3.2 服务启动类及mybatis、swagger配置类
3.3 验证
启动dttask-server,访问 http://127.0.0.1:9088/doc.html#/home,可看到如下 swagger界面
4. 工程加入git版本控制
工程加入git版本控制,就不在这里截图了,几步操作,不会的人可以网上搜搜,此时代码作为我们的0.1版本
5.数据库脚本
