创建MyBatisPlus配置类

package com.yootk.provider.config;import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
public class MyBatisPlusConfig { // MybatisPlus配置类@Beanpublic MybatisPlusInterceptor getMybatisPlusInterceptor() {MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();	// 拦截器interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL)); 	// 分页处理return interceptor;}
}

创建IDeptDAO数据接口

package com.yootk.provider.dao;import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.yootk.provider.vo.Dept;
import org.apache.ibatis.annotations.Mapper;@Mapper
public interface IDeptDAO extends BaseMapper<Dept> { // DAO接口开发完成
}

在生产端需要提供有业务接口的实现子类

@Service
public class DeptServiceImpl implements IDeptService {@Autowiredprivate IDeptDAO deptDAO;@Overridepublic Map<String, Object> split(int currentPage, int lineSize, String column, String keyword) {QueryWrapper<Dept> wrapper = new QueryWrapper<>();wrapper.like(column, keyword); // 设置模糊查询操作int count = this.deptDAO.selectCount(wrapper); // 统计个数// 实现数据的查询处理IPage<Dept> page = this.deptDAO.selectPage(new Page<>(currentPage, lineSize, count), wrapper);Map<String, Object> map = new HashMap<>(); // 包装返回结果map.put("allDepts", page.getRecords()); //数据记录map.put("allRecorders", page.getTotal());  //总数map.put("allPages", page.getPages());  //页数return map;}
}
