MyBatis环境搭建
1、1.pom.xml中引入MyBatis核心依赖
在pom.xml中引入相关依赖
<?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">
<modelVersion>4.0.0</modelVersion>
<!--项目配置-->
<groupId>com.qf</groupId>
<artifactId>hello-mybatis</artifactId>
<version>1.0-SNAPSHOT</version>
<!--依赖-->
<dependencies>
<!--MyBatis核心依赖-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.4.6</version>
</dependency>
<!--MySql驱动依赖-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.47</version>
</dependency>
</dependencies>
</project>
2、2.创建MyBatis配置文件
创建并配置mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<!--MyBatis配置-->
<configuration>
<!--JDBC环境配置、选中默认环境-->
<environments default="MySqlDB">
<!--MySql数据库环境配置-->
<environment id="MySqlDB">
<!--事务管理-->
<transactionManager type="JDBC"/>
<!--连接池-->
<dataSource type="org.apache.ibatis.datasource.pooled.PooledDataSourceFactory">
<property name="driver" value="com.mysql.jdbc.Driver"/>
<!-- &转义& -->
<property name="url" value="jdbc:mysql://localhost:3306/x?useUnicode=true&characterEncoding=utf-8"/>
<property name="username" value="xxx"/>
<property name="password" value="xxx"/>
</dataSource>
</environment>
</environments>
<!--Mapper注册-->
<mappers>
<!--注册Mapper文件的所在位置-->
<mapper resource="xxxMapper.xml"/>
</mappers>
</configuration>
