Dbutils 连接数据库

用了JDBC后接着学习Dbutils连接数据库

1.添加驱动包

Class.forName("oracle.jdbc.driver.OracleDriver");

2.获取数据库连接

Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@fwwb-439:1521:home", "scott", "tiger");

3.DButils连接

QueryRunner runner = new QueryRunner();

4.执行SQL 

List<Emp> list = runner.query(conn,"select * from emp",new BeanListHandler<Emp>(Emp.class));

循环遍历
for(int i=0;i<list.size();i++){

Emp emp = list.get(i);

System.out.println(emp.getEmpno()+","+emp.getEname()+","+emp.getJob()+","+emp.getSal());

}
