如何使用spring执行sql文件

application.properties 配置好

spring.datasource.url=jdbc:mysql://localhost:3306/demo
spring.datasource.username=root
spring.datasource.password=

pom.xml 加上这俩

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-jdbc</artifactId>
		</dependency>
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<scope>runtime</scope>
		</dependency>

Main.java

@Slf4j
@Component
public class Main implements CommandLineRunner {

    @Autowired
    DataSource dataSource;

    @Override
    public void run(String... args) throws Exception {
        val a = new FileSystemResource("a.sql");
        val b = new FileSystemResource("b.sql");
        val resourceDatabasePopulator = new ResourceDatabasePopulator();
        resourceDatabasePopulator.addScripts(a, b);
        resourceDatabasePopulator.execute(dataSource);
    }
}

其中 a.sql b.sql 存在当前项目根目录
主要就是用 resourceDatabasePopulator 这个类
