jpa查询用法，jpa查询字段开头，jpa查询字段以什么开始

        JPAQueryFactory jpaQueryFactory = new JPAQueryFactory(entityManager);

        QTSscDeptAgPO tSscDeptAgPO = QTSscDeptAgPO.tSscDeptAgPO;
        List<TSscDeptAgPO> fetch = jpaQueryFactory.selectFrom(tSscDeptAgPO)
                .where(tSscDeptAgPO.pwOrgCode.startsWith(Optional.ofNullable(vo.getOrgCode()).orElse("")))
                .fetch();

jpa中limit查询，jpa分页，jpa偏移量

jpaQueryFactory.selectFrom(workTodoPO).where(workTodoPO.workType.eq(
                "project_score").and(workTodoPO.finish.eq("0"))).orderBy(workTodoPO.id.asc()).offset(i).limit(500).fetch();

 jpa分页处理

package com.peony.common.util;

import com.peony.common.entity.PPage;
import com.querydsl.jpa.impl.JPAQuery;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.experimental.Accessors;

import java.util.List;

public class PPageUtil {


    public static <T>  PPageData page(JPAQuery<T> jpaQuery, PPage pPage){
        if(pPage.getPage()==null||pPage.getPage()<=0){
            pPage.setPage(1);
        }
        if(pPage.getPageSize()==null||pPage.getPageSize()<=0){
            pPage.setPageSize(10);
        }
        PPageData pPageData = new PPageData();
        Long l = jpaQuery.fetchCount();
        pPageData.setTotal(l.intValue());
        pPageData.setPage(pPage.getPage());
        List<T> fetch = jpaQuery.offset((long) (pPage.getPage() - 1) *pPage.getPageSize()).limit(pPage.getPageSize()).fetch();
        pPageData.setData(fetch);
        return pPageData;
    }


    @Data
    @Accessors(chain = true)
    public static class PPageData{
        @ApiModelProperty(value = "总条数")
        private int total;

        @ApiModelProperty(value = "当前页")
        private int page;
        @ApiModelProperty(value = "数据")
        private List data;
    }

}

        QWorkTodoPO workTodoPO = QWorkTodoPO.workTodoPO;
        JPAQuery<WorkTodoPO> workTodoPOJPAQuery = jpaQueryFactory.selectFrom(workTodoPO);
        workTodoPOJPAQuery.where(workTodoPO.finish.eq("0"));

        }
