1.准备好底层实现
1-1、页面返回结果类 PageResult
package com.cm.aps.page;
import java.util.List;
public class PageResult {
/**
* 当前页码
*/
private int pageNum;
/**
* 每页数量
*/
private int pageSize;
/**
* 记录总数
*/
private long totalSize;
/**
* 页码总数
*/
private int totalPages;
/**
* 分页数据
*/
private List<?> content;
public int getPageNum() {
return pageNum;
}
public void setPageNum(int pageNum) {
this.pageNum = pageNum;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public long getTotalSize() {
return totalSize;
}
public void setTotalSize(long totalSize) {
this.totalSize = totalSize;
}
public int getTotalPages() {
return totalPages;
}
public void setTotalPages(int totalPages) {
this.totalPages = totalPages;
}
public List<?> getContent() {
return content;
}
public void setContent(List<?> content) {
this.content = content;
}
}
1-2.页面控制类 PageRequest
package com.cm.aps.page;
import java.util.HashMap;
import java.util.Map;
public class PageRequest {
/**
* 当前页码
*/
private int pageNum;
/**
* 每页数量
*/
private int pageSize;
public int getPageNum() {
return pageNum;
}
public void setPageNum(int pageNum) {
this.pageNum = pageNum;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
}
1-3、页面操作类
package com.cm.aps.page;
import com.github.pagehelper.PageInfo;
public class PageUtils {
public static PageResult getPageResult(PageRequest pageRequest, PageInfo<?> pageInfo) {
PageResult pageResult = new PageResult();
pageResult.setPageNum(pageInfo.getPageNum());
pageResult.setPageSize(pageInfo.getPageSize());
pageResult.setTotalSize(pageInfo.getTotal());
pageResult.setTotalPages(pageInfo.getPages());
pageResult.setContent(pageInfo.getList());
return pageResult;
}
}
2.修改服务接口
package com.cm.aps.service;
import com.cm.aps.model.S_apscode;
import com.cm.aps.page.PageRequest;
import com.cm.aps.page.PageResult;
import java.util.List;
public interface S_apscodeService extends CurdService {
//根据制程代号查询制程
S_apscode findbycode(String code);
//查询全部
List<S_apscode> findAll();
//根据代号删除
int deletebycode(String code);
//添加
int insert(S_apscode s_apscode);
//更新
int update(S_apscode s_apscode);
//分页
PageResult findPage(PageRequest pageRequest);
}
3.修改服务类
package com.cm.aps.service.impl;
import com.cm.aps.dao.S_apscodeMapper;
import com.cm.aps.model.S_apscode;
import com.cm.aps.page.PageRequest;
import com.cm.aps.page.PageResult;
import com.cm.aps.page.PageUtils;
import com.cm.aps.service.S_apscodeService;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import org.apache.ibatis.annotations.Param;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class S_apscodeServiceimpl implements S_apscodeService {
@Autowired
private S_apscodeMapper s_apscodeMapper;
@Override
public S_apscode findbycode(String code) {
return s_apscodeMapper.findbycode(code);
}
@Override
public List<S_apscode> findAll() {
return s_apscodeMapper.findAll();
}
@Override
public int deletebycode(String code) {
return s_apscodeMapper.deletebycode(code);
}
@Override
public int insert(@Param(value = "s_apscode") S_apscode s_apscode) {
return s_apscodeMapper.insert(s_apscode);
}
@Override
public int update(S_apscode s_apscode) {
return s_apscodeMapper.update(s_apscode);
}
@Override
public PageResult findPage(PageRequest pageRequest) {
return PageUtils.getPageResult(pageRequest, getPageInfo(pageRequest));
}
private PageInfo<S_apscode> getPageInfo(PageRequest pageRequest) {
int pageNum = pageRequest.getPageNum();
int pageSize = pageRequest.getPageSize();
PageHelper.startPage(pageNum, pageSize);
List<S_apscode> sysMenus = s_apscodeMapper.selectPage();
return new PageInfo<S_apscode>(sysMenus);
}
@Override
public int save(Object record) {
S_apscode recordCopy=(S_apscode)record;
if((recordCopy.getId()==null)){
//INSERT
return insert(recordCopy);
}else{
return s_apscodeMapper.updateById(recordCopy);
}
}
@Override
public int delete(Object record) {
return 0;
}
@Override
public int delete(List records) {
return 0;
}
@Override
public Object findById(Long id) {
return null;
}
}
4.修改映射接口
package com.cm.aps.dao;
import com.cm.aps.model.S_apscode;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface S_apscodeMapper {
//根据制程代号查询制程
S_apscode findbycode(String code);
//查询全部
List<S_apscode> findAll();
//新增
int insert(@Param(value = "s_apscode")S_apscode s_apscode);
//删除
int deletebycode(String code);
//修改
int updateById(@Param(value = "s_apscode")S_apscode s_apscode);
int update(@Param(value = "s_apscode")S_apscode s_apscode);
//分页
List<S_apscode> selectPage();
}
5.添加外部接口
package com.cm.aps.controller;
import com.cm.aps.model.S_apscode;
import com.cm.aps.page.PageRequest;
import com.cm.aps.service.S_apscodeService;
import com.cm.aps.util.HttpResult;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
@RestController
@RequestMapping("Apscode")
@CrossOrigin
public class S_apscodeController {
@Autowired
private S_apscodeService s_apscodeService;
@GetMapping(value="/findByapscode")
public Object findbycode(@RequestParam String code) {
return s_apscodeService.findbycode(code);}
@GetMapping(value="/findAll")
public Object findAll() {
return s_apscodeService.findAll();
}
@PostMapping(value="/delete")
public Object deletebycode(@RequestParam(value = "code") String code){
return s_apscodeService.deletebycode(code);}
@PostMapping(value="/insert")
public Object insert(@RequestBody(required = true) S_apscode s_apscode){
return s_apscodeService.insert(s_apscode);};
@PostMapping(value="/findPage")
public Object findPage(@RequestBody PageRequest pageQuery) {
return s_apscodeService.findPage(pageQuery);
}
@PostMapping(value="/update")
public Object update(@RequestBody(required = true) S_apscode s_apscode){
return s_apscodeService.update(s_apscode);};
}
6.测试
