上面这个错误是我引入了一个动画jquery-2.1.4.min.js引入可能有问题但是不耽误程序，动画还能动就没有管它
先说基本的操作数据库的连接在util包下创建了DBO类
package cn.edu.hpu.util;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class DBO {
static String url="jdbc:mysql://localhost:3306/dl";
static String user="root";
static String password="123";
static{
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static Connection getConnection() {
Connection conn=null;
try {
conn=DriverManager.getConnection(url, user, password);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return conn;
}
public static void close(Statement st,ResultSet rs,Connection conn) {
try {
if(st!=null) {
st.close();
}
if(rs!=null) {
rs.close();
}
if(conn!=null) {
conn.close();
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void close(PreparedStatement pst,Connection conn) {
try {
if(pst!=null) {
pst.close();
}
if(conn!=null) {
conn.close();
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
以及验证码的servlet
package cn.edu.hpu.servlet;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.util.Random;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class PicCodeGenerator extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
BufferedImage bi=new BufferedImage(68,22,BufferedImage.TYPE_INT_BGR);
Graphics g=bi.getGraphics();
Color color=new Color(224,205,19);
g.setColor(color);
g.fillRect(0, 0, 68,22);
char [] c="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".toCharArray();
Random random= new Random();
int len=c.length;
int temp;
StringBuffer sb=new StringBuffer(4);
for(int i = 0 ; i<4 ; i++){
char index = c[(int)(0+Math.random()*c.length)];
Font font = new Font("幼圆",Font.BOLD,25);
Color clo = new Color(random.nextInt(255));
g.setFont(font);
g.setColor(clo);
g.drawString(index+"",i*15,18);
g.setColor(new Color(random.nextInt(150),random.nextInt(220),random.nextInt(180)));
sb.append(index);
}
for(int i=0;i<5;i++) {
g.drawLine(random.nextInt(68),random.nextInt(22),random.nextInt(68), random.nextInt(22));
}
request.getSession().setAttribute("piccode", sb.toString());
ImageIO.write(bi, "JPG", response.getOutputStream());
}
}
以及分页的一些类
package cn.edu.hpu.dao;
import java.util.List;
public class PageBean {
private int pc;
private int ps;
private int tr;
private String url;
private List beanlist;
public int getTp() {

return tr%ps==0?tp:tp+1;
}
public int getPc() {
return pc;
}
public void setPc(int pc) {
this.pc = pc;
}
public int getPs() {
return ps;
}
public void setPs(int ps) {
this.ps = ps;
}
public int getTr() {
return tr;
}
public void setTr(int tr) {
this.tr = tr;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public List getBeanlist() {
return beanlist;
}
public void setBeanlist(List beanlist) {
this.beanlist = beanlist;
}
}
package cn.edu.hpu.dao;
import cn.edu.hpu.domain.Student;
public interface StudentDao {
//分页的实现
public PageBean findByPageBean(int pc);
}

/**

*/
int ps =10;
try {
conn = DBO.getConnection();
st = (Statement) conn.createStatement();
/**
* 2.tr 通过查询数据库
*/
int tr = 0;
String sql = "SELECT COUNT(*) FROM student";
rs = st.executeQuery(sql);
while(rs.next()){
tr = rs.getInt("count(*)");//count并不是数据库里的列名，默认为列名
//rs.getInt(1);
}
/**
* 3. 数据集合
* SELECT * FROM t_user LIMIT 0,3
*
* 1 ： 当前页第一条记录的下标 begin （pc-1）*ps
* 2 ： 每页查询的记录数 ps
*/
List list = new ArrayList();
int begin = (pc-1)*ps;
sql = "SELECT * FROM student LIMIT "+ begin +","+ps;
rs = st.executeQuery(sql);
//遍历结果集
while(rs.next()){
Student student = new Student();
student.setId(rs.getInt("id"));
student.setName(rs.getString("name"));
student.setPassword(rs.getString("password"));
student.setAddress(rs.getString("address"));
student.setBirthday(rs.getString("birthday"));
student.setGender(rs.getString("gender"));
student.setSid(rs.getString("sid"));
//将遍历产生的对象，添加到数据集合中
list.add(student);
}
//生成PageBean对象
PageBean pageBean = new PageBean();
pageBean.setPc(pc);
pageBean.setPs(ps);
pageBean.setTr(tr);
pageBean.setBeanlist(list);
return pageBean;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
package cn.edu.hpu.servlet;

}
由于学生查询时不能看到其他学生的密码，所以在创建一个servelt
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import cn.edu.hpu.dao.PageBean;
import cn.edu.hpu.domain.Student;
import cn.edu.hpu.service.StudentService;
public class StudentServlet1 extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
StudentService studentService = new StudentService();
//获取请求路径
//http://localhost:8080/PageBeanDemon/StudentServlet?null&pc=6
//http://localhost:8080/PageBeanDemon/
//${pageContext.request.contextPath }/StudentServlet?null&pc=${pb.pc -1}
String uri = request.getRequestURI()+"?"+request.getQueryString();
int index=uri.indexOf("StudentServlet");
if(index==-1) {
uri="http://localhost:8080/student/StudentServlet?null";
}
index = uri.lastIndexOf("&pc=");
if(index != -1 ){
uri = uri.substring(0,index);
}
//获取当前页页码
int pc = 1;
String param = request.getParameter("pc");
if(param != null && !param.trim().isEmpty()){
//将string类型强制转化为Int类型
pc = Integer.parseInt(param);
}
PageBean pageBean = studentService.findByPageBean(pc);
//pageBean.setPc(pc);
pageBean.setUrl(uri);
/*
List list = pageBean.getBeanlist();
1.
for(int i=0; i
//将数据放到Request域
request.setAttribute("pb", pageBean);
//转发
request.getRequestDispatcher("s.jsp").forward(request, response);
}
}
我的学生管理系统分为两个部分老师和学生 先说老师吧
一 老师可以对学生进行增删改查和查看学生的所有信息
1创建一个老师类 不需要太多变量用户名密码即可以及相应的get set方法
package cn.edu.hpu.domain;
public class Teacher {
private int id;
private String username;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
2.这里写老师的登录注册的接口
package cn.edu.hpu.dao;
import cn.edu.hpu.domain.Teacher;
public interface TeacherManager {
public Teacher CheckLoding(String name,String password);
public boolean Register(Teacher teacher);
}
以及接口的实现类
package cn.edu.hpu.daoimpl;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import cn.edu.hpu.dao.TeacherManager;
import cn.edu.hpu.domain.Teacher;
import cn.edu.hpu.util.DBO;
public class TeacherManagerImpl implements TeacherManager {
@Override
public Teacher CheckLoding(String name, String password) {
// TODO Auto-generated method stub
Teacher teacher=null;
Connection conn=null;
Statement st=null;
ResultSet rs=null;
String sql="select * from teacher";
conn=DBO.getConnection();
try {
st=conn.createStatement();
rs=st.executeQuery(sql);
while(rs.next()) {
String nm=rs.getString("username");
String psd=rs.getString("password");
if(nm.equals(name)&& psd.equals(password)) {
teacher=new Teacher();
teacher.setUsername(nm);
teacher.setPassword(psd);
}
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return teacher;
}
@Override
public boolean Register(Teacher teacher) {
// TODO Auto-generated method stub
boolean flag=false;
String sql="insert into teacher(username,password) values(?,?)";
Connection conn=null;
PreparedStatement pst=null;
conn=DBO.getConnection();
try {
pst=conn.prepareStatement(sql);
pst.setString(1,teacher.getUsername());
pst.setString(2, teacher.getPassword());
pst.executeUpdate();
flag=true;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return flag;
}
}
3建立老师的登录jsp
