mybatis
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"?>
