springboot+jpa+mysql的小例子

model/user层

镜像数据库

package com.alphaz.core.pojo.viewmodel.prepay;import javax.persistence.*;
import java.math.BigDecimal;@Entity(name = "tb_prepaybill")
public class PrepayBillModel  {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long enterpriseid;private String ssq;private Integer jzzt;private String billno;private Integer incomeState;private Long xmid;private Integer zsfs;private BigDecimal xssr;private String xssl;private String yjsl;private BigDecimal fbk;private BigDecimal yjzzs;private BigDecimal sjyjzzs;private String bz;public Long getEnterpriseid() {return enterpriseid;}public void setEnterpriseid(Long enterpriseid) {this.enterpriseid = enterpriseid;}public String getSsq() {return ssq;}public void setSsq(String ssq) {this.ssq = ssq;}public Integer getJzzt() {return jzzt;}public void setJzzt(Integer jzzt) {this.jzzt = jzzt;}public String getBillno() {return billno;}public void setBillno(String billno) {this.billno = billno;}public Integer getIncomeState() {return incomeState;}public void setIncomeState(Integer incomeState) {this.incomeState = incomeState;}public Long getXmid() {return xmid;}public void setXmid(Long xmid) {this.xmid = xmid;}public Integer getZsfs() { return zsfs; }public void setZsfs(Integer zsfs) { this.zsfs = zsfs; }public BigDecimal getXssr() { return xssr; }public void setXssr(BigDecimal xssr) { this.xssr = xssr; }public String getXssl() { return xssl; }public void setXssl(String xssl) { this.xssl = xssl; }public String getYjsl() { return yjsl; }public void setYjsl(String yjsl) { this.yjsl = yjsl; }public BigDecimal getFbk() { return fbk; }public void setFbk(BigDecimal fbk) { this.fbk = fbk; }public BigDecimal getYjzzs() { return yjzzs; }public void setYjzzs(BigDecimal yjzzs) { this.yjzzs = yjzzs; }public BigDecimal getSjyjzzs() { return sjyjzzs; }public void setSjyjzzs(BigDecimal sjyjzzs) { this.yjzzs = sjyjzzs; }public String getBz() { return bz; }public void setBz(String bz) { this.bz = bz; }@Overridepublic String toString() {return "PrepayBillModel{" +"enterpriseid=" + enterpriseid +", ssq='" + ssq + '\'' +", jzzt=" + jzzt +", billno='" + billno + '\'' +", incomeState=" + incomeState +", xmid=" + xmid +", zsfs=" + zsfs +", xssr=" + xssr +", xssl='" + xssl + '\'' +", yjsl='" + yjsl + '\'' +", fbk=" + fbk +", yjzzs=" + yjzzs +", sjyjzzs=" + sjyjzzs +", bz='" + bz + '\'' +'}';}
}

Dao层

别忘了继承jpa类（提供一系列数据库操作方法）

package com.alphaz.core.dao;import com.alphaz.core.pojo.viewmodel.prepay.PrepayBillModel;
import org.mapstruct.Mapper;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;import java.util.List;@Mapperpublic interface PrepayBillDAO extends JpaRepository<PrepayBillModel,Integer> {List<PrepayBillModel> getPrepayBillModelsByXmid(String xmid);List<PrepayBillModel> getPrepayBillModelsBySsq(String ssq);List<PrepayBillModel> getPrepayBillModelsByBillno(String billno);@Query("select b from tb_prepaybill b where b.xmid=:xmid and b.ssq=:ssq")List<PrepayBillModel> getPrepayBillModelsByXmidAndSsq(String xmid,String ssq);@Query("select b from tb_prepaybill b where b.xmid=:xmid and b.ssq=:ssq")List<PrepayBillModel> getPrepayBillModelsByBillnoAndSsq(String billno,String ssq);@Query("select b from tb_prepaybill b where b.xmid=:xmid and b.ssq=:ssq")List<PrepayBillModel> getPrepayBillModelsByBillnoAndXmid(String billno,String xmid);@Query("select b from tb_prepaybill b where b.xmid=:xmid and b.ssq=:ssq")List<PrepayBillModel> getPrepayBillModelsByBillnoAndXmidaAndSsq(String billno,String xmid,String ssq);}

service层

package com.alphaz.core.service;import com.alphaz.core.dao.PrepayBillDAO;import com.alphaz.core.pojo.viewmodel.prepay.PrepayBillModel;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Service;import java.util.List;@Servicepublic class PrepayBillService {@AutowiredPrepayBillDAO prepayBillDAO ;public void addprepaybill(PrepayBillModel prepayBillModel) {prepayBillDAO.save(prepayBillModel);}public Page<PrepayBillModel> getPrepayBillModelByPage(Pageable pageable) {return prepayBillDAO.findAll(pageable);}public List<PrepayBillModel> getPrepayBillModelsByXmid(String xmid){return prepayBillDAO.getPrepayBillModelsByXmid(xmid);}public List<PrepayBillModel> getPrepayBillModelsBySsq(String ssq){return prepayBillDAO.getPrepayBillModelsBySsq(ssq);}public List<PrepayBillModel> getPrepayBillModelsByXmidAndSsq(String xmid,String ssq){return prepayBillDAO.getPrepayBillModelsByXmidAndSsq(xmid,ssq);}public List<PrepayBillModel> getPrepayBillModelsByBillnoAndSsq(String billno,String ssq){return prepayBillDAO.getPrepayBillModelsByBillnoAndSsq(billno,ssq);}public List<PrepayBillModel> getPrepayBillModelsByBillnoAndXmid(String billno,String xmid){return prepayBillDAO.getPrepayBillModelsByBillnoAndXmid(billno,xmid);}public List<PrepayBillModel> getPrepayBillModelsByBillnoAndXmidaAndSsq(String billno,String xmid,String ssq){return prepayBillDAO.getPrepayBillModelsByBillnoAndXmidaAndSsq(billno,xmid,ssq);}}

controller层

package com.alphaz.app.controller;import com.alphaz.core.pojo.viewmodel.prepay.PrepayBillModel;
import com.alphaz.core.service.PrepayBillService;
import com.alphaz.core.utils.redis.RedisUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import javax.annotation.Resource;
import java.util.List;@RestController
@RequestMapping("/prepay")
public class prepayBillController {@ResourcePrepayBillService prepayBillService;@Autowiredprivate RedisUtil redisUtil;@GetMapping("/findAll")public void findAll(){PageRequest pageable = PageRequest.of(2,3);Page<PrepayBillModel> page =prepayBillService.getPrepayBillModelByPage(pageable);System.out.println("总页数："+page.getTotalPages());System.out.println("总记录数："+page.getTotalElements());System.out.println("查询结果："+page.getContent());System.out.println("当前页数："+page.getNumber()+1);System.out.println("当前页记录数："+page.getNumberOfElements());System.out.println("每页记录数："+page.getSize());}@GetMapping("/search")public void search(){List<PrepayBillModel> bs1 = prepayBillService.getPrepayBillModelsByBillnoAndSsq("1","712");}@GetMapping("/save")public void save(){PrepayBillModel prepayBillModel=new PrepayBillModel();prepayBillModel.setBillno("22");prepayBillService.addprepaybill(prepayBillModel);}
}
