mybatis-geneator

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简单的增删改查以及简单的vue+element ui前端页面，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)

<!-- Velocity视图所需jar -->
        <dependency>
            <groupId>org.apache.velocity</groupId>

        </dependency>

              </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、生成模块代码工具类(并生成简单的Vue页面)

public class MybatisGeneratorUtil {
    public MybatisGeneratorUtil() {
    }
 
    public static void generator(String jdbcDriver, String jdbcUrl, String jdbcUsername, String jdbcPassword, String controllerModule, String serviceModule, String daoModule, String database, String tablePrefix, String tableList, String controllerPackagePrefix, String servicePackagePrefix, String daoPackagePrefix, Map<String, String> lastInsertIdTables) throws Exception {

五、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);
    }

六、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);

/**

 */
@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
     *

    @GetMapping(value = "/list")

        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);

    }
 
    /**

     *

    @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");
    }
 
    /**

    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

    @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);
    }
 
}

九：生成标准的vue页面和vue.js文件

// api
// Created by Administrator on 2019-06-20T10:55:15.236.
import request from '@/utils/requestJson'
 
// 查找数据
export const listApi = params => {
  return request.get('/cityInfo/list', { params: params })
}
// 添加数据
export const addApi = params => {
  return request.post('/cityInfo/add', params)
}
// 修改数据
export const updateApi = params => {
  return request.post('/cityInfo/update', params)
}
// 删除数据
export const deleteApi = params => {
  return request.get('/cityInfo/delete', { params: params })
}
// 详细数据
export const detailApi = params => {
  return request.get('/cityInfo/detail', { params: params })
}

// 编辑
