Spring 整合 Mybatis

• 使用纯注解开发：17. 纯注解开发

一、原始 MyBatis 使用

1. MyBatis 程序核心对象

2. 整合 MyBatis

二、Spring + MyBatis

1. 配置 pom 坐标

<dependencies>
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-context</artifactId>
		<version>5.0.13.RELEASE</version>
		<scope>compile</scope>
	</dependency>
	 <!-- druid 连接池 -->
	<dependency>
		<groupId>com.alibaba</groupId>
		<artifactId>druid</artifactId>
		<version>1.2.16</version>
	</dependency>
	<!-- mysql 连接驱动 -->
	<dependency>
		<groupId>mysql</groupId>
		<artifactId>mysql-connector-java</artifactId>
		<version>5.1.46</version>
	</dependency>
	<!-- spring-jdbc， 版本与 spring-context 版本一致-->
	<dependency>
		<groupId>org.springframework</groupId>
		<artifactId>spring-jdbc</artifactId>
		<version>5.0.13.RELEASE</version>
	</dependency>
	<!-- mybatis -->
	<dependency>
		<groupId>org.mybatis</groupId>
		<artifactId>mybatis</artifactId>
		<version>3.5.13</version>
	</dependency>
	<!-- spring 整合 mybatis  -->
	<dependency>
		<groupId>org.mybatis</groupId>
		<artifactId>mybatis-spring</artifactId>
		<version>1.3.0</version>
	</dependency>
</dependencies>

2. 增加 Mybatis 配置类

MybatisConfig.java

public class MyBatisConfig {
	@Bean
	public SqlSessionFactoryBean sqlSessionFactory(DataSource dataSource) {
		SqlSessionFactoryBean ssfb = new SqlSessionFactoryBean();
		// 扫描类型别名的包： <typeAliases>
		ssfb.setTypeAliasesPackage("cn.pangcy.domain");
		ssfb.setDataSource(dataSource);
		return ssfb;
	}

	@Bean
	public MapperScannerConfigurer mapoerScannerConfigurer() {
		MapperScannerConfigurer msc = new MapperScannerConfigurer();
		// 扫描映射包： <mappers>
		msc.setBasePackage("cn.pangcy.dao");
		return msc;
	}
}

3. SpringConfig

@Configuration
@ComponentScan("cn.pangcy")
// 注意一定要有 Jdbc 连接池的配置类
@Import({JdbcConfig.class, MybatisConfig.class})
public class SpringConfig {}
