Spring Framework与JDBC

Spring与JDBC的整合

工程结构

Java代码

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;

public class Main {
    public static void main(String[] args) {
        // 1.获取Spring容器
        ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
        // 2.根据id获取bean对象
        JdbcTemplate jdbcTemplate = (JdbcTemplate) ac.getBean("jdbcTemplate");
        // 3.执行操作
        jdbcTemplate.execute("insert into info(name) values('小明')");
    }
}
