第十四篇:SpringBoot2.x整合MyBatisGenerator
在这里简单介绍一下如何整合Mybatis自动生成代码的插件MybatisGenerator
引入插件
需要在pom.xml文件中的
org.mybatis.generator
mybatis-generator-maven-plugin
1.3.5
mysql
mysql-connector-java
5.1.28
runtime
src/main/resources/generatorConfig.xml
true
引入依赖后右侧的maven project侧边栏中的Plugins选项会多出一个mybatis-generator

设置配置文件
接下来在resources文件夹中创建一个generatorConfig.xml文件用于自动构建代码的配置
运行插件
配置就结束了，最后运行一下，这里找到在Maven Project的mybatis-generator:generator选项，双击运行

UserMapper.java
package priv.gabriel.dao;
import java.util.List;
import org.apache.ibatis.annotations.Param;
import priv.gabriel.model.User;
import priv.gabriel.model.UserExample;
public interface UserMapper {
long countByExample(UserExample example);
int deleteByExample(UserExample example);
int deleteByPrimaryKey(Integer id);
int insert(User record);
int insertSelective(User record);
List selectByExample(UserExample example);
User selectByPrimaryKey(Integer id);
int updateByExampleSelective(@Param("record") User record, @Param("example") UserExample example);
int updateByExample(@Param("record") User record, @Param("example") UserExample example);
int updateByPrimaryKeySelective(User record);

}
可以看到已经帮我们生产了关于CRUD的绝大代码，再结合之前的通用mapper就可以解决绝大部分的问题啦
