今天蠢了一上午才弄出這玩意，話不多說上代碼！

package com.sie.demo.config; import com.baomidou.mybatisplus.annotation.DbType;import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration; /** * @author liaozhifeng * @date 2021/7/31 11:14 * @Version 1.0 */@Configuration@ConditionalOnClass(value = {PaginationInterceptor.class})public class MybatisPlusConfig { // 最新版 @Bean public MybatisPlusInterceptor mybatisPlusInterceptor() {MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();//數據庫的配置DbType.ORACLE 根據自己的數據庫選擇interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.ORACLE));return interceptor; }}2、service層的代碼

package com.sie.demo.service.impl; import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;import com.baomidou.mybatisplus.core.metadata.IPage;import com.baomidou.mybatisplus.extension.plugins.pagination.Page;import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;import com.sie.demo.entity.Users;import com.sie.demo.entity.vo.PageUserVo;import com.sie.demo.mapper.UserMapper;import com.sie.demo.service.UserService;import lombok.extern.slf4j.Slf4j;import org.springframework.stereotype.Service;import org.springframework.util.DigestUtils; import javax.annotation.Resource; import javax.servlet.http.HttpSession;import java.util.List; /** * @author liaozhifeng * @date 2021/7/27 14:03 * @Version 1.0 */@Service@Slf4jpublic class UserServiceImpl extends ServiceImpl<UserMapper, Users> implements UserService { @Resource UserMapper userMapper; /** * 分頁查詢用戶 * @param currentPage * @param pageSize * @return */ @Override public PageUserVo selectAll(long currentPage, long pageSize) {IPage<Users> userPage = new Page<>(currentPage, pageSize);//參數一是當前頁，參數二是每頁個數IPage<Users> iPage = userMapper.selectPage(userPage, null);List<Users> list = iPage.getRecords();Long total = iPage.getTotal();PageUserVo pageUserVo = new PageUserVo(list, total);return pageUserVo; }}3、controller層 RetResult是我自己定義的一個統一返回的泛型對象

package com.sie.demo.controller; import com.baomidou.mybatisplus.core.conditions.Wrapper;import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;import com.baomidou.mybatisplus.core.metadata.IPage;import com.baomidou.mybatisplus.extension.conditions.query.QueryChainWrapper;import com.baomidou.mybatisplus.extension.plugins.pagination.Page;import com.sie.demo.entity.RetCode;import com.sie.demo.entity.RetResponse;import com.sie.demo.entity.RetResult;import com.sie.demo.entity.Users; import com.sie.demo.entity.vo.PageUserVo;import com.sie.demo.service.impl.UserServiceImpl;import com.sie.demo.util.TokenUtil;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.*; import javax.annotation.Resource;import javax.servlet.http.HttpSession;import java.util.List; @Controller@RestController@RequestMapping('user')@Slf4jpublic class UserController { @Autowired UserServiceImpl userService; /** * * * @param currentPage * @param pageSize * @return */ @GetMapping('selectAll') public RetResult<PageUserVo> selectAll(long currentPage, long pageSize) {log.info(currentPage+pageSize+'=========================');PageUserVo pageUserVo = userService.selectAll(currentPage,pageSize);return RetResponse.makeOKRsp(pageUserVo); }}
