我使用的是mysql数据库。我的数据库大小为552 MB。当我运行我的项目时，它需要超过5分钟。如果我使用100 MB以下/小数据库，那么它运行速度很快。我该如何先运行我的项目。感谢。

你可以去Hikari Connection Pool.Return Hikari DataSource对象。示例代码如下：

import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;


@Bean
public DataSource dataSource() {
    // In classpath from spring-boot-starter-web
    final Properties props = new Properties();
    props.put("driverClassName", "com.mysql.jdbc.Driver");
    props.put("jdbcUrl", "jdbc:mysql://localhost:3306/master?createDatabaseIfNotExist=false");
    props.put("username", "root");
    props.put("password", "mysql");
    HikariConfig hc = new HikariConfig(props);
    HikariDataSource ds = new HikariDataSource(hc);
    return ds;
}

我怎样才能快速运行我的项目？
