基于mapperScan 的多数据源

@Configuration
//指定mapper所在的包路径
@MapperScan(basePackages = "com.backstage.base.car",sqlSessionFactoryRef = "carSqlSessionFactory")
public class CarDataSourceConfig {
//    @Primary
    @Bean(name = "carDataSource")
　　//在properties中添加数据源信息
    @ConfigurationProperties("spring.datasource.car")
    public DataSource masterDataSource(){
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "carSqlSessionFactory")
    public SqlSessionFactory sqlSessionFactory(@Qualifier("carDataSource") DataSource dataSource) throws Exception {
        SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
        sessionFactoryBean.setDataSource(dataSource);

        sessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver()
                .getResources("classpath*:com.backstage.base.car/*.xml"));
        return sessionFactoryBean.getObject();
    }
}
