小弟写的一个Demo，mybatis和Spring-Boot整合

很简单的....

@Configuration
@EnableTransactionManagement
@MapperScan("com.*.*.mapper")
public class DataBaseConfig {

	private final Logger log = LoggerFactory.getLogger(DataBaseConfig.class);

	@Bean
	@Primary
	@ConfigurationProperties(prefix = "datasource.primary")
	public DataSource dataSource() {
		log.debug("Configuring Datasource");
		return new DruidDataSource();
	}

	@Bean
	public PlatformTransactionManager txManager() {
		return new DataSourceTransactionManager(dataSource());
	}

	@Bean
	public SqlSessionFactory sqlSessionFactoryBean() throws Exception {

		SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
		sqlSessionFactoryBean.setDataSource(dataSource());

		PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();

		sqlSessionFactoryBean.setMapperLocations(resolver
				.getResources("classpath:/mapper/*.xml"));
		return sqlSessionFactoryBean.getObject();
	}

}

？？

mapper注入不就行了
