如何在IoC容器外部进行简单的Spring JDBC事务？

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.DefaultTransactionDefinition;
import org.springframework.transaction.support.TransactionCallback;
import org.springframework.transaction.support.TransactionTemplate;

public class TransactionExample {

    public static void main(String[] args) {
        // 创建DataSource实例
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/test");
        dataSource.setUsername("username");
        dataSource.setPassword("password");

        // 创建JdbcTemplate实例
        JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);

        // 创建PlatformTransactionManager实例
        PlatformTransactionManager transactionManager = new DataSourceTransactionManager(dataSource);

        // 创建TransactionTemplate实例
        TransactionTemplate transactionTemplate = new TransactionTemplate(transactionManager);

        // 执行事务操作
        transactionTemplate.execute(new TransactionCallback<Void>() {
            @Override
            public Void doInTransaction(TransactionStatus status) {
                // 执行SQL语句
                jdbcTemplate.update("INSERT INTO users (name, age) VALUES (?, ?)", "Tom", 20);
                jdbcTemplate.update("INSERT INTO users (name, age) VALUES (?, ?)", "Jerry", 25);

                // 如果需要回滚事务，可以调用status.setRollbackOnly()方法
                // status.setRollbackOnly();

                return null;
            }
        });
    }
}
