Springboot集成mybatis plus时的分页使用
1.添加架包
com.baomidou.mybatis-plus
2.配置文件

单表分页
Java代码
public static void testPageListUser() {
Page page = new Page(1,10);
Map params=new HashMap();
condition.put("name", "测试");
//String name="测试";
List lstUser = userDao.selectUserList(page,params);
} 在人人框架中使用
单表不用写sql
package com.ziyun.erp.modules.member.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.HashMap;
import java.util.Map;
import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.baomidou.mybatisplus.plugins.Page;
import com.baomidou.mybatisplus.service.impl.ServiceImpl;
import io.renren.common.utils.PageUtils;
import io.renren.common.utils.Query;
import com.ziyun.erp.modules.member.dao.ConfigMemberLevelDao;
import com.ziyun.erp.modules.member.entity.ConfigMemberLevelEntity;
import com.ziyun.erp.modules.member.service.ConfigMemberLevelService;
import org.springframework.transaction.annotation.Transactional;
@Service("configMemberLevelService")
public class ConfigMemberLevelServiceImpl extends ServiceImpl implements ConfigMemberLevelService {
@Autowired
private ConfigMemberLevelDao configMemberLevelDao;
@Override
public PageUtils queryPage(Map params) {
Page page = this.selectPage(
new Query(params).getPage(),
new EntityWrapper()
);
return new PageUtils(page);
} 多表查询分页需自己写sql
ServiceImpl
package com.ziyun.erp.modules.member.service.impl;
import com.ziyun.erp.common.utils.MD5;
import com.ziyun.erp.modules.member.dao.*;
import com.ziyun.erp.modules.member.entity.*;
import io.renren.common.exception.RRException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.math.BigDecimal;
import java.util.List;
import java.util.Map;
import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.baomidou.mybatisplus.plugins.Page;
import com.baomidou.mybatisplus.service.impl.ServiceImpl;
import io.renren.common.utils.PageUtils;
import io.renren.common.utils.Query;
import com.ziyun.erp.modules.member.service.UserBaseInfoService;
import org.springframework.transaction.annotation.Transactional;
@Service("userBaseInfoService")
public class UserBaseInfoServiceImpl extends ServiceImpl implements UserBaseInfoService {
@Autowired
private UserBaseInfoDao userBaseInfoDao;
@Autowired
private UserWalletDao userWalletDao;
@Autowired
private UserAdvanceDao userAdvanceDao;
@Autowired
private UserCreditDao userCreditDao;
@Autowired
private UserPointDao userPointDao;
@Autowired
private UserMemberLevelDao userMemberLevelDao;
@Autowired
private UserLoginAccountDao userLoginAccountDao;
@Override
public PageUtils selectAllList(Map params) {
Page page = new Page<>();
page.setCurrent(Integer.valueOf(params.get("page").toString()));
page.setSize(Integer.valueOf(params.get("limit").toString()));
List list = userBaseInfoDao.getAllUserInfo(page,params);
page.setRecords(list);
return new PageUtils(page);
} Dao层方法的参数传入Pagination page即可
List getAllUserInfo(Pagination page,Map map); Xml
