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 後面跟的是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">

        </dependencies>
        <configuration>
          <overwrite>true</overwrite>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

完成上面的配置  然後打開maven-->plugins--->mybatis-generator--->mybatis-generator:generate
運行mybatis-generator:generate完成自動生成所需要的文件

三.添加數據到數據庫中

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();
        }
    }
}
運行程序顯示 說明添加成功（其他刪，改，查相似）
