oj开发备忘

数据库相关

先贴一段裸的数据库连接.

DriverManagerDataSource dataSource=new DriverManagerDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/test");
dataSource.setUsername("root");
dataSource.setPassword("");
  
JdbcTemplate jdbcTemplate=new JdbcTemplate(dataSource);
jdbcTemplate.execute("create table test(id int primary key,name varchar(32))");
