java建立临时数据源DataSource

package com.***.***.util;

import java.sql.SQLException;
import javax.sql.DataSource;
import org.apache.commons.dbcp.BasicDataSource;
/*
 * 获得数据源DataSource,临时用,不需要启动容器
 */
public class DataSourceConn extends BasicDataSource {

 public DataSource getDataSource() {
  DataSource ds = null;

  super.setDriverClassName("com.mysql.jdbc.Driver");

//数据库是testdb1 
  super.setUrl("jdbc:mysql://localhost:3306/testdb1?useUnicode=true&characterEncoding=UTF-8");
  super.setUsername("root");
  super.setPassword("123456");
  try {
   ds = super.createDataSource();
  } catch (SQLException e) {
   e.printStackTrace();
  }
  return ds;
 }
}

 

使用数据源：

public class Test {
 static DataSourceConn tds = new DataSourceConn();
 private static SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(tds.getDataSource());

 /**
  * @param args
  * @throws IOException
  * @throws ParseException
  */
 public static void main(String[] args) throws IOException{
  // TODO Auto-generated method stub
  
  
  List list = (List)jdbcTemplate.queryForList("select * from table1");
  

  //以下是业务数据处理
  
 }

}
