JS如何实现数据库数据更新

1、首先创建News，然后实现其中方法package cn.hpu.model;public class News { private int id; private String title; private String context;public int getId() {return id;}

3、public String getContext() {return context;}public void setContext(String context) {this.context = context;} }然后创建操作接口package cn.hpu.service;import cn.hpu.model.News;

5、import cn.hpu.model.News;import cn.hpu.util.DBO;public class NewsMaImpl implements NewsMa{public List<News> getNews() {// TODO Auto-generated method stubreturn null;}public boolean add(News news) {return true;} }

7、创建登陆页面并实现验证。此处省略 实现添加的时候别忘了接口add里面的public boolean add(News news) {// TODO Auto-generated method stubboolean flag=false;Connection conn=null;PreparedStatement pst =null;try {
