temp.java

这是个利用J2EE编写的如何利用java语言进行与数据库MySQL连接的程序

import java.util.Iterator;
import java.util.List;

import dao.UserDAO;
import po.UserPO;

		upo.setEmail("taotao");
		upo.setAddress("taotao");
		UserDAO dao = new UserDAO();
		if(dao.logonOff(upo)) {
			System.out.println("success");
		}*/
		UserDAO dao = new UserDAO();
		List l = dao.showUser();
		if(l!=null&&l.size()>0) {
			Iterator i = l.iterator();
			while(i.hasNext()) {
