MyBatis官方文档索引

mybatis的官方文档写得挺详细的，确很难找到入口，整理了一下；

• mybatis官网文档 | mybatis中文文档
• mybatis-spring文档 | mybatis-spring中文文档
• mybatis-spring-boot-autoconfigure文档

最原始的用法

1String resource = "org/mybatis/example/mybatis-config.xml";
2InputStream inputStream = Resources.getResourceAsStream(resource);
3SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
4
5SqlSession session = sqlSessionFactory.openSession();
6try {
7  BlogMapper mapper = session.getMapper(BlogMapper.class);
8  Blog blog = mapper.selectBlog(101);
9} finally {
10  session.close();
11}

结合Spring的用法

1<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
2  <property name="dataSource" ref="dataSource" />
3</bean>
4<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
5  <property name="basePackage" value="org.mybatis.spring.sample.mapper" />
6</bean>

结合了spring-boot的用法

自动检查DataSource,自动扫描查找带@Mapper注解的Mapper类，酸酸爽爽。
