【项目复盘】springboot项目中使用mybatis-plus进行分页

springboot项目中使用mybatis-plus进行分页

引入依赖

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.1.2</version>
        </dependency>

配置类

@EnableTransactionManagement
@Configuration
public class MybatisPlusConfig {

    @Bean
    public PaginationInterceptor paginationInterceptor(){
        return new PaginationInterceptor();
    }
}

实体类

如：

@TableName("car") 
public class Car implements Serializable {
    @TableId(type = IdType.AUTO)
    private Long id;
    private String carNumber;
    private String carNo;
    private String color;
    private String belongClass;
    private Boolean deleted;
}

@TableName()设置对应的表名
@TableId() 设置主键及主键生成策略
@TableField() 设置属性对应的字段名

持久层

@Mapper
public interface CarDao extends BaseMapper<Car> {

}

@Mapper注册bean
继承mybatis-plus的BaseMapper类

业务层

  IPage<Car> iPage = carDao.selectPage(page, queryWrapper);
  return new Result<IPage<Car>>(20000,"获取成功",iPage);

iPage就是要的数据，格式如下：

 {
		"current": 0,
		"pages": 0,
		"records": [
			{
				"age": 0,
				"id": 0,
				"idcard": "",
				"name": "",
				"remarks": "",
				"sex": 0
			}
		],
		"searchCount": true,
		"size": 0,
		"total": 0
}
