spring框架学习记录 4 jdbcTemplate搭建

项目结构

jdbcTemplate.xml

db.properties

#连接mysql数据库配置
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/jdbc_test
jdbc.username=root
jdbc.password=password

Main.java

package jdbcTemplate.test;

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

import java.util.List;
import java.util.Map;

public class Main {
    public static void main(String[] args) {
        System.out.println("jdbcTemplate");
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("jdbcTemplate.xml");
        JdbcTemplate jdbcTemplateBean = applicationContext.getBean("jdbcTemplate", JdbcTemplate.class);
        System.out.println("......start......");
        List> list = jdbcTemplateBean.queryForList("select * from tb_user");
        for (Map map : list) {
            System.out.println(map.toString());
        }
    }
}
