java 连接oracle 字符集_Java连接Oracle数据库，编码格式转换

学习东西不忘记下笔记：

dbhelper类，各种数据库都合适。

public classDBHelper {

//mysql数据库//public static final String url = "jdbc:mysql://127.0.0.1:3306/test";//public static final String name = "com.mysql.jdbc.Driver";//public static final String user = "root";//public static final String password = "******";

//Oracle数据库

public static final String url = "jdbc:oracle:thin:@127.0.0.1:1521:test";public static final String name = "oracle.jdbc.driver.OracleDriver";public static final String user = "test";public static final String password = "1";public Connection conn = null;public PreparedStatement pst = null;publicDBHelper(String sql) {try{

Class.forName(name);//指定连接类型

conn = DriverManager.getConnection(url, user, password);//获取连接

pst = conn.prepareStatement(sql)
