使用mybatis-plus实现分页查询

1. pom.xml导入mybatis-plus插件

       <dependency>
              <groupId>com.baomidou</groupId>
              <artifactId>mybatis-plus-boot-starter</artifactId>  
              <version>3.0.6</version>
      </dependency>

2. 编写config 实现分页插件

    @Configuration
    @MapperScan("mapper")
     public class MybatisPlusConfig {
        @Bean
        public PaginationInterceptor paginationInterceptor() {
          return new PaginationInterceptor();
        }
     }

3. 编写controller(传入pageNo, pageSize)

    IPage<T> iPage = tService.page(new Page<>(pageNo,pageSize));

iPage包括:
{
"records": [], list
"total": 0,总数
"size": 3,pageSize
"current": 1,pageNo
"searchCount": true,
"pages": 0 总页数
}

附:mapper,service结构(如需代码构造器Mybatis-Plus代码构造器)

//mapper
@Mapper
public interface Tmapper extends BaseMapper<T> {
}
//service
public interface TService extends IService<T> {
}
//serviceImpl
@Service
public class TServiceImpl extends ServiceImpl<Tmapper,T> implements TService {
}
