MyBatis框架

MyBatis第一步创建Maven

不用模板

 

 

 

 修改id软件的添加maven插件

 

 添加依赖

 

 其中所有内容改为

<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">

    <artifactId>mybatistest</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>

            <version>3.5.2</version>

        <dependency>

            <!--               <scope>test</scope>-->
            <scope>compile</scope>
        </dependency>
    </dependencies>
    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>

</project>

之后打开Navicat for MySQL
新建连接
name：xxx
密码:1234

右键空白区域新建数据库 数据库名mybatis 字符集utf8 utf-8 排序规则utf8_general

再选择查询→新建查询

 

 查询代码

use mybatis;
create table users(
uid int primary key auto_increment,
uname varchar(20) not null,
uage int not null
);
insert into users(uid,uname,uage) values(null,'张三',20),(null,'李四',18);
