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 -->

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=

七、自动生成XML文件
<?xml version="1.0" encoding="UTF-8"?>

八、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;

/**

*
* @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);
}
/**

*
* @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");
}
/**

*/
@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);
}
}
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
// Created by Administrator on 2019-06-20T10:55:15.236.

十、配图(本案例用springboot 项目构建，模块化开发)
