java当中JDBC当中JNDI用来查找dataSource的例子

[学习笔记]

8.JNDI用来查找dataSource的例子：

import javax.naming.InitialContext;
import javax.naming.Context;

import com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource;

import java.util.Properties;
import net.sourceforge.jtds.jdbcx.*;
public class ClassPut {
public static void main(String a[]) {
try {
/* JtdsDataSource dataSource=new JtdsDataSource();
dataSource.setServerName("localhost");
dataSource.setDatabaseName("NorthWind");
dataSource.setUser("sa");
dataSource.setPassword("1234");
*/
MysqlConnectionPoolDataSource ds = new MysqlConnectionPoolDataSource();
ds.setURL("jdbc:mysql://localhost:3306/test");
ds.setUser("root");
ds.setPassword("1234");


Properties prop = new Properties();
prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.fscontext.RefFSContextFactory");

Context ctx=new InitialContext(prop);
/*here the following statement writes a file .bindings under the f Disk. because this project is under the f disk.*/
ctx.rebind("abc",ds);

} catch (Exception e) {
e.printStackTrace();
}
}
}
上面的程序只是存入硬盘，想查找出来得用下面的程序：

import javax.naming.InitialContext;
import javax.naming.Context;

import com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource;

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
import net.sourceforge.jtds.jdbcx.*;
public class ClassGet {
public static void main(String a[]) {

try {
Properties prop = new Properties();
prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.fscontext.RefFSContextFactory");
Context ctx=new InitialContext(prop);
