mybatis-plus-boot-starter 复合主键

在mybatis-plus-boot-starter中，复合主键的配置方式如下所示：[3]
在实体类中，使用@MppMultiId注解来标注复合主键的字段。例如：

@TableName("etl_job")
public class Job implements Serializable {
    private static final long serialVersionUID = 1L;
    
    @MppMultiId // 复合主键
    private String etlSystem;
    
    @MppMultiId // 复合主键
    private String etlJob;
    
    // 其他属性和方法
}

在上述例子中，Job类使用@MppMultiId注解标注了etlSystem和etlJob两个字段作为复合主键。这样配置后，mybatis-plus会根据这两个字段来确定唯一的记录。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
