【Spring教程12】Spring框架实战：Spring整合Mybatis全面深入详解

@Configuration
public class MyBatisConfig {
 
    @Bean
    public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dataSource);
        // 可以设置更多的MyBatis全局配置 like 'mapperLocations' and 'configLocation'
        return sqlSessionFactoryBean.getObject();
    }
 
    @Bean
    public DataSource dataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/myapp");
        dataSource.setUsername("root");
        dataSource.setPassword("password");
        return dataSource;
    }
 
    @Bean
    public MapperScannerConfigurer mapperScannerConfigurer() {
        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
        mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
        mapperScannerConfigurer.setBasePackage("com.myapp.mapper");
        return mapperScannerConfigurer;
    }
}

这个配置类展示了如何在Spring中配置MyBatis的SqlSessionFactory、DataSource以及自动扫描Mapper接口。这是一个基本的配置模板，可以根据实际情况进行调整和扩展。
