多数据源导致PageHelper失效

@Configuration
public class MyBatisConfiguration {

    private static final Logger logger = LoggerFactory.getLogger(MyBatisConfiguration.class);

    @Bean
    public PageHelper pageHelper() {
        logger.info("注册mybatis分页插件PageHelper");
        PageHelper pageHelper = new PageHelper();
        Properties p = new Properties();
        p.setProperty("offsetAsPageNum", "true");
        p.setProperty("rowBoundsWithCount", "true");
        p.setProperty("reasonable", "true");
        pageHelper.setProperties(p);
        return pageHelper;
    }
}

public class PageHelperUtil {
    @SuppressWarnings("unchecked")
    public static  PagedResult toPagedResult(List datas) {
        PagedResult result = new PagedResult();
        if (datas instanceof Page) {
            @SuppressWarnings("rawtypes")
            Page page = (Page) datas;
            result.setPageNo(page.getPageNum());
            result.setPageSize(page.getPageSize());
            result.setDataList(page.getResult());
            result.setTotal(page.getTotal());
            result.setPages(page.getPages());
        } else {
            result.setPageNo(1);
            result.setPageSize(datas.size());
            result.setDataList(datas);
            result.setTotal(datas.size());
        }
        return result;
    }

    public static  PagedResult toPagedLimitResult(List datas, Integer pageNo, Integer pageSize, long count) {
        PagedResult result = new PagedResult();
        if (CollectionUtils.isEmpty(datas)) {
            result.setPageNo(pageNo);
            result.setPageSize(pageSize);
            result.setDataList(new ArrayList<>());
            result.setTotal(0);
            result.setPages(0);
            result.setReadCount(count);
            return result;
        }

        int pages = datas.size() / pageSize;
        int totalRowNum = datas.size();
        int fromIdx = (pageNo - 1) * pageSize;
        int toIdx = pageNo * pageSize > totalRowNum ? totalRowNum : pageNo * pageSize;
        if (datas.size() % pageSize != 0) {
            pages++;
        }
        if (fromIdx > toIdx) {
            result.setPageNo(pageNo);
            result.setPageSize(pageSize);
            result.setDataList(new ArrayList<>());
            result.setTotal(datas.size());
            result.setPages(pages);
            result.setReadCount(count);
            return result;
        }

        List dataList = datas.subList(fromIdx, toIdx);
        result.setPageNo(pageNo);
        result.setPageSize(pageSize);
        result.setDataList(dataList);
        result.setTotal(datas.size());
        result.setPages(pages);
        result.setReadCount(count);
        return result;
    }

}

PageHelper.startPage(pageNo, pageSize);
List holdCombinedBos = commonPositionMapper.selectHoldCombined();
PagedResult holdCombinedBoPagedResult = PageHelperUtil.toPagedResult(holdCombinedBos);

查询的集合不是Page的实例导致分页失效

 public static  PagedResult toPagedResult(List datas) {
        PagedResult result = new PagedResult();
        if (datas instanceof Page) {
        }else {
            result.setPageNo(1);
            result.setPageSize(datas.size());
            result.setDataList(datas);
            result.setTotal(datas.size());
        }
        return null;
}

使用SqlSessionFactory重新加载pageHelper

 	@Bean(name = "primarySqlSessionFactory")
    @Primary
    public SqlSessionFactory primarySqlSessionFactory(@Qualifier("primaryDataSource") DataSource primaryDataSource)
            throws Exception {
        final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
        sessionFactory.setDataSource(primaryDataSource);
        // 重新加载pageHelper
        sessionFactory.setPlugins(pageHelper());
        sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver()
                .getResources(MAPPER_LOCATION));
        sessionFactory.setConfiguration(globalConfiguration());
        return sessionFactory.getObject();
    }
