1.链接数据库
2.详细配置
生成方式
文件生成目录配置
生成注解、方法配置
File-Settings设置选项中配置:接口后缀名,设置为Dao 则生成的即可名为MytestDao ;Mapper则为MyTestMapper
3.生成后的代码
提示:这里我建的表名为mytest 生成的规则是首字母大写,如果想要达到MyTest这种效果,则在建表示已下划线分割即可 my_test ——> MyTest
1.接口—Mytest
package com.zds.tbl.dao;
import com.zds.tbl.po.Mytest;
import com.zds.tbl.po.MytestExample;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface MytestDao {
/**
* 根据条件查询总数
* @param example
* @return
*/
long countByExample(MytestExample example);
/**
* 根据条件进行删除
* @param example 可以组装条件
* @return
*/
int deleteByExample(MytestExample example);
/**
* delete by primary key 根据主键进行删除
* @param id primaryKey
* @return deleteCount
*/
int deleteByPrimaryKey(Integer id);
/**
* 全量插入实体类字段值到表中
* insert record to table
* @param record the record
* @return insert count
*/
int insert(Mytest record);
/**
*主键或唯一索引在现有表中已经存在,则会执行更新操作
* @param record
* @return
*/
int insertOrUpdate(Mytest record);
/**
* 主键或唯一索引在现有表中已经存在,则会执行更新操作
* 选择性的插入或者更新,如果字段值!=null则进行更新或者插入
* @param record
* @return
*/
int insertOrUpdateSelective(Mytest record);
/**
* 选择性的插入,如果字段值!=null则插入
* insert record to table selective
* @param record the record
* @return insert count
*/
int insertSelective(Mytest record);
/**
* 根据条件进行查询
* @param example
* @return
*/
List<Mytest> selectByExample(MytestExample example);
/**
* 根据主键进行查询
* select by primary key
* @param id primary key
* @return object by primary key
*/
Mytest selectByPrimaryKey(Integer id);
/**
* 根据条件进行更新
* @param record 实体,字段值!=null的进行更新
* @param example 更新条件
* @return
*/
int updateByExampleSelective(@Param("record") Mytest record, @Param("example") MytestExample example);
/**
* 根据条件全量表更新
* @param record 实体,全量表更新即使字段值为null也会进行更新
* @param example 更新条件
* @return
*/
int updateByExample(@Param("record") Mytest record, @Param("example") MytestExample example);
/**
* 根据主键进行选择性更新
* update record selective
* @param record the updated record
* @return update count
*/
int updateByPrimaryKeySelective(Mytest record);
/**
* 根据主键进行表全量更新
* update record
* @param record the updated record
* @return update count
*/
int updateByPrimaryKey(Mytest record);
/**
* 根据主键集,批量全表更新
* @param list
* @return
*/
int updateBatch(List<Mytest> list);
/**
* 根据主键集,选择性批量更新
* @param list 字段值!=null的进行更新
* @return
*/
int updateBatchSelective(List<Mytest> list);
/**
* 批量插入
* @param list
* @return
*/
int batchInsert(@Param("list") List<Mytest> list);
}
2.实体—Mytest

import lombok.AllArgsConstructor;

import lombok.Data;
import lombok.NoArgsConstructor;
@ApiModel(value="com-zds-tbl-po-Mytest")
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Mytest {

@ApiModelProperty(value="id")
private Integer id;
/**

@ApiModelProperty(value="名称")
