Java框架如何处理数据库重连机制？

import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.jdbc.datasource.DriverManagerDataSource;

import javax.sql.DataSource;
import java.sql.SQLException;

@Configuration
public class DatabaseConfiguration {

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUrl("jdbc:mysql://localhost:3306/mydatabase");
        dataSource.setUsername("root");
        dataSource.setPassword("password");

        // 设置重连策略
        dataSource.setConnectionInitSqls("SELECT 1");
        dataSource.setValidationQuery("SELECT 1");
        dataSource.setMaxWait(30000);
        dataSource.setMaxIdleTime(60);
        dataSource.setMinIdle(2);

        return dataSource;
    }

    @Bean
    public DataSourceTransactionManager transactionManager(@Qualifier("dataSource") DataSource dataSource) {
        return new DataSourceTransactionManager(dataSource);
    }
}
