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;

*/
@ApiModelProperty(value = "城市名称")

/**

*/
@ApiModelProperty(value = "城市编码")
private String cityCode;
/**

*
* city_info.province
*/
@ApiModelProperty(value = "省份")
private String province;
private static final long serialVersionUID = 1L;
public Integer getCityId() {

public void setCityId(Integer cityId) {

}

}
public String getProvince() {

}

}
@Override

sb.append("]");
return sb.toString();
}
@Override
public boolean equals(Object that) {
if (this == that) {
return true;
}

}
if (getClass() != that.getClass()) {

}
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()))

}
@Override
