一、简介

在使用mybatis时我们需要重复的去创建pojo类、mapper文件以及dao类并且需要配置它们之间的依赖关系，比较麻烦且做了大量的重复工作，mybatis官方也发现了这个问题，

因此给我们提供了mybatis generator工具来帮我们自动创建pojo类、mapper文件以及dao类并且会帮我们配置好它们的依赖关系

mybatis-geneator是一款mybatis自动代码生成工具，可以通过配置，快速生成mapper和xml文件以及部分dao service controller简单的增删改查，极大的提高了我们的开发效率。

二、maven需要的主要依赖(由于使用springboot模块化开发,依赖太多，不一一列举)

 <dependency>

        <groupId>org.mybatis.generator</groupId>

     <artifactId>mybatis-generator-core</artifactId>

        <version>1.3.5</version>

      </dependency>

<plugin>

           <groupId>org.mybatis.generator</groupId>

           <artifactId>mybatis-generator-maven-plugin</artifactId>

           <version>1.3.2</version>

           <executions>

              <execution>

                 <id>Generate MyBatis Files</id>

                 <goals>

                    <goal>generate</goal>

                 </goals>

                 <phase>generate</phase>

                 <configuration>

                    <verbose>true</verbose>

                    <overwrite>true</overwrite>

                 </configuration>

              </execution>

           </executions>

 

三、generator.properties配置文件(本案例数据库只有一个表)

# generator.controller.module 可以设置为空，为空不生成代码 generator.controller.module=project-web # generator.service.module 可以设置为空，为空不生成代码 generator.service.module=project-service # generator.dao.module 不允许为空 generator.dao.module=project-dao generator.controller.package.prefix=edu.nf.project generator.service.package.prefix=edu.nf.project generator.dao.package.prefix=edu.nf.project generator.table.prefix=city_ generator.table.list= generator.database=weather generator.jdbc.driver=com.mysql.cj.jdbc.Driver generator.jdbc.url=jdbc:mysql://localhost:3306/weather?useSSL=false&useUnicode=true&characterEncoding=utf8&tinyInt1isBit=false&serverTimezone=UTC generator.jdbc.username=root generator.jdbc.password=root

四、生成器(Generator)

/** * 代码生成类 * * @author ywb */
public class Generator { private static String CONTROLLER_MODULE = PropertiesFileUtil.getInstance("generator").get("generator.controller.module"); private static String SERVICE_MODULE = PropertiesFileUtil.getInstance("generator").get("generator.service.module"); private static String DAO_MODULE = PropertiesFileUtil.getInstance("generator").get("generator.dao.module"); private static String CONTROLLER_PACKAGE_PREFIX = PropertiesFileUtil.getInstance("generator").get("generator.controller.package.prefix"); private static String SERVICE_PACKAGE_PREFIX = PropertiesFileUtil.getInstance("generator").get("generator.service.package.prefix"); private static String DAO_PACKAGE_PREFIX = PropertiesFileUtil.getInstance("generator").get("generator.dao.package.prefix"); private static String TABLE_PREFIX = PropertiesFileUtil.getInstance("generator").get("generator.table.prefix"); private static String TABLE_LIST = PropertiesFileUtil.getInstance("generator").get("generator.table.list"); private static String DATABASE = PropertiesFileUtil.getInstance("generator").get("generator.database"); private static String JDBC_DRIVER = PropertiesFileUtil.getInstance("generator").get("generator.jdbc.driver"); private static String JDBC_URL = PropertiesFileUtil.getInstance("generator").get("generator.jdbc.url"); private static String JDBC_USERNAME = PropertiesFileUtil.getInstance("generator").get("generator.jdbc.username"); private static String JDBC_PASSWORD = PropertiesFileUtil.getInstance("generator").get("generator.jdbc.password"); /** * 需要insert后返回主键的表配置，key:表名,value:主键名 */
    private static Map<String, String> LAST_INSERT_ID_TABLES = new HashMap<>();/** * 自动代码生成 */
    public static void main(String[] args) throws Exception { MybatisGeneratorUtil.generator(JDBC_DRIVER, JDBC_URL, JDBC_USERNAME, JDBC_PASSWORD, CONTROLLER_MODULE, SERVICE_MODULE, DAO_MODULE, DATABASE, TABLE_PREFIX, TABLE_LIST, CONTROLLER_PACKAGE_PREFIX, SERVICE_PACKAGE_PREFIX, DAO_PACKAGE_PREFIX, LAST_INSERT_ID_TABLES); }

五、自动生成出来的mapper

package edu.nf.project.mapper; import edu.nf.project.model.CityInfo; import edu.nf.project.model.CityInfoExample; import java.util.List; import org.apache.ibatis.annotations.Param; public interface CityInfoMapper { long countByExample(CityInfoExample example); int deleteByExample(CityInfoExample example); int deleteByPrimaryKey(Integer cityId); int insert(CityInfo record); int insertSelective(CityInfo record); List<CityInfo> selectByExample(CityInfoExample example); CityInfo selectByPrimaryKey(Integer cityId); int updateByExampleSelective(@Param("record") CityInfo record, @Param("example") CityInfoExample example); int updateByExample(@Param("record") CityInfo record, @Param("example") CityInfoExample example); int updateByPrimaryKeySelective(CityInfo record); int updateByPrimaryKey(CityInfo record); }

五、自动生成出来的Model

package edu.nf.project.model; import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; import java.io.Serializable; import org.springframework.format.annotation.DateTimeFormat; /** * * city_info * * @mbg.generated */
public class CityInfo implements Serializable { /** * 城市编号 * * city_info.city_id */ @ApiModelProperty(value = "城市编号") private Integer cityId; /** * 城市名称 * * city_info.city_name */ @ApiModelProperty(value = "城市名称") private String cityName; /** * 城市编码 * * city_info.city_code */ @ApiModelProperty(value = "城市编码") private String cityCode; /** * 省份 * * city_info.province */ @ApiModelProperty(value = "省份") private String province; private static final long serialVersionUID = 1L; public Integer getCityId() { return cityId; } public void setCityId(Integer cityId) { this.cityId = cityId; } public String getCityName() { return cityName; } public void setCityName(String cityName) { this.cityName = cityName == null ? null : cityName.trim(); } public String getCityCode() { return cityCode; } public void setCityCode(String cityCode) { this.cityCode = cityCode == null ? null : cityCode.trim(); } public String getProvince() { return province; } public void setProvince(String province) { this.province = province == null ? null : province.trim(); } @Override public String toString() { StringBuilder sb = new StringBuilder(); sb.append(getClass().getSimpleName()); sb.append(" ["); sb.append("Hash = ").append(hashCode()); sb.append(", cityId=").append(cityId); sb.append(", cityName=").append(cityName); sb.append(", cityCode=").append(cityCode); sb.append(", province=").append(province); sb.append("]"); return sb.toString(); } @Override public boolean equals(Object that) { if (this == that) { return true; } if (that == null) { return false; } if (getClass() != that.getClass()) { return false; } CityInfo other = (CityInfo) that; return (this.getCityId() == null ? other.getCityId() == null : this.getCityId().equals(other.getCityId())) && (this.getCityName() == null ? other.getCityName() == null : this.getCityName().equals(other.getCityName())) && (this.getCityCode() == null ? other.getCityCode() == null : this.getCityCode().equals(other.getCityCode())) && (this.getProvince() == null ? other.getProvince() == null : this.getProvince().equals(other.getProvince())); } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + ((getCityId() == null) ? 0 : getCityId().hashCode()); result = prime * result + ((getCityName() == null) ? 0 : getCityName().hashCode()); result = prime * result + ((getCityCode() == null) ? 0 : getCityCode().hashCode()); result = prime * result + ((getProvince() == null) ? 0 : getProvince().hashCode()); return result; } }

六、自动生成XML文件

<?xml version="1.0" encoding="UTF-8"?>

</mapper>

七、以及service dao controller(这里只复制controller)

package edu.nf.project.controller; import com.wang.common.base.BaseController; import com.wang.common.model.base.result.DataResult; import com.wang.common.uitl.IdGenerator; import com.wang.common.model.page.PageInfoResult; import com.wang.common.model.page.PageParam; import edu.nf.project.model.CityInfo; import edu.nf.project.model.CityInfoExample; import edu.nf.project.service.CityInfoService; import com.github.pagehelper.PageInfo; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import io.swagger.annotations.Api; import io.swagger.annotations.ApiOperation; import org.apache.shiro.authz.annotation.RequiresPermissions; import org.springframework.web.bind.annotation.*; import javax.annotation.Resource; import java.util.List; /** * controller * Created by Administrator on 2019-06-20T11:55:04.44. * * @author Administrator */ @RestController @ResponseBody @RequestMapping(value = "/cityInfo") @Api(value = "控制器", description = "管理") public class CityInfoController extends BaseController { private static final Logger LOGGER = LoggerFactory.getLogger(CityInfoController.class); @Resource private CityInfoService cityInfoService; /** * 列表 * * @param pageParam 分页参数 * @return DataResult */ @GetMapping(value = "/list") @ApiOperation(value = "列表") public PageInfoResult<CityInfo> list(PageParam pageParam) { CityInfoExample cityInfoExample = new CityInfoExample(); List<CityInfo> cityInfoList = cityInfoService.selectByExampleForStartPage(cityInfoExample, pageParam.getPageNum(), pageParam.getPageSize()); long total = cityInfoService.countByExample(cityInfoExample); return new PageInfoResult<>(cityInfoList, total); } /** * 添加 * * @param cityInfo 数据 * @return DataResult */ @PostMapping(value = "/add") @ApiOperation(value = "添加") @RequiresPermissions("cityInfo:add") public DataResult add(@RequestBody CityInfo cityInfo) { cityInfo.setCityId((int)(IdGenerator.getId())); cityInfoService.insertSelective(cityInfo); return new DataResult("success", "保存成功"); } /** * 删除 * * @param id 主键 * @return DataResult */ @GetMapping(value = "/delete") @ApiOperation(value = "删除") @RequiresPermissions("cityInfo:delete") public DataResult delete(Long id) { cityInfoService.deleteByPrimaryKey(id); return new DataResult("success", "删除成功"); } /** * 修改 * * @param cityInfo 数据 * @return DataResult */ @PostMapping(value = "/update") @ApiOperation(value = "修改") @RequiresPermissions("cityInfo:update") public DataResult update(@RequestBody CityInfo cityInfo) { CityInfoExample cityInfoExample = new CityInfoExample(); cityInfoExample.createCriteria().andCityIdEqualTo(cityInfo.getCityId()); cityInfoService.updateByExampleSelective(cityInfo, cityInfoExample); return new DataResult("success", "修改成功"); } /** * 详情 * * @param id 主键 * @return DataResult */ @GetMapping(value = "/detail") @ApiOperation(value = "详情") @RequiresPermissions("cityInfo:detail") public DataResult<CityInfo> detail(Long id) { CityInfo cityInfo = cityInfoService.selectByPrimaryKey(id); return new DataResult<>(cityInfo); } }

 八、配图(本案例用springboot 项目构建，模块化开发)
