我用mysql數據庫我database.properties文件。我的數據庫大小爲552 MB。當我運行我的項目需要5分鐘以上。如果我使用100 MB以下/小型數據庫，那麼它運行得很快。我怎樣才能運行我的項目。 謝謝。

你可以去下面阿光連接Pool.Return阿光數據源object.Sample代碼：

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; 
}
