测试代码

public class JdbcTest {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("applicationContext.xml");
        JdbcTemplate jdbcTemplate = (JdbcTemplate) app.getBean("jdbcTemplate");
        List<Map<String, Object>> maps = jdbcTemplate.queryForList("select * from user_01");
        System.out.println(maps);
    }
}

报错

 Could not load properties; nested exception is java.io.FileNotFoundException: class path resource [druid.properties] cannot be opened because it does not exist

重新编译一下然后再启动

我去，我重新创建了一个properties文件。内容相同，没想到就加载成功了。。。。。。。
