Spring Boot中自动执行sql脚本的实现

CREATE TABLE IF NOT EXISTS people(
  persion_id BIGINT NOT NULL AUTO_INCREMENT,
  first_name VARCHAR(20),
  last_name VARCHAR(20),
  PRIMARY KEY (persion_id)
);

import org.springframework.jdbc.datasource.init.DatabasePopulator;

public class BatchTaskDataSourceInitializer {
  /**

   */
  @Value("classpath:schema-all.sql")
  private Resource businessScript;

   * @return
   */
  @Bean
  public DataSourceInitializer dataSourceInitializer(final DataSource dataSource) {
    final DataSourceInitializer initializer = new DataSourceInitializer();
    // 设置数据源
    initializer.setDataSource(dataSource);

  }
}
