MyBatis-generator+maven完成mybatis例子
一.generatorconfig.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<context id="mysqlgenerator" targetRuntime="MyBatis3">
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/ygy"
userId="root"
password="***" />
<!--targetProject 后面跟的是model放的位置 targetPackage放的包名-->
<javaModelGenerator targetPackage="com.nomico271.model" targetProject="src" />
<sqlMapGenerator targetPackage="com.nomico271.mapper" targetProject="src" />
<javaClientGenerator type="XMLMAPPER" targetPackage="com.nomico271.mapper" targetProject="src" />
<table tableName="ygy1"/>
</context>
</generatorConfiguration>
二.pox.xml文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

完成上面的配置 然后打开maven-->plugins--->mybatis-generator--->mybatis-generator:generate
运行mybatis-generator:generate完成自动生成所需要的文件
三.添加数据到数据库中
import com.nomico271.model.Ygy1;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import java.io.IOException;
import java.io.Reader;
public class main {
static Reader reader;
static SqlSession session;
public static void main(String[] args) {
try {
reader= Resources.getResourceAsReader("ygy.xml");
} catch (IOException e) {
e.printStackTrace();
}
finally {
SqlSessionFactory sqlSessionFactory=new SqlSessionFactoryBuilder().build(reader);
session=sqlSessionFactory.openSession();
Ygy1 ygy1=new Ygy1();
ygy1.setId(3);
ygy1.setName("sdhuaik");
session.insert("insert",ygy1);
session.commit();
session.close();
}
}
}
运行程序显示 说明添加成功(其他删,改,查相似)
