本文實例為大家分享了JSP學生信息管理系統源碼，JSP+Servlet+Javabean+JDBC+MySQL，供大家參考，具體內容如下
1.service層，進行數據庫操作
package com.service;/** * 負責學生信息的所有數據庫操作，增刪改查 */import java.sql.Connection;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.sql.SQLException;import java.util.ArrayList;import java.util.List; import com.model.stuInfo; public class stuInfoService { private Connection conn; private PreparedStatement pstmt;//執行sql語句 public stuInfoService() { conn = new com.conn.conn().getCon(); } public boolean addStu(stuInfo stu) {//插入學生數據 try { pstmt = conn.prepareStatement("insert into studentinfo" + "(Nickname,truename,sex,birthday,major,course,interest,remark) " + "values(?,?,?,?,?,?,?,?)"); pstmt.setString(1, stu.getNickname()); pstmt.setString(2, stu.getTruename()); pstmt.setByte(3, stu.getSex()); pstmt.setString(4, stu.getbirthday()); pstmt.setString(5, stu.getmajor()); pstmt.setString(6, stu.getcourses()); pstmt.setString(7, stu.getinterests()); pstmt.setString(8, stu.getremark()); pstmt.executeUpdate(); return true; } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); return false; } }//查詢所喲學生信息 public List<stuInfo> queryAllStu() {//查詢學生數據 List<stuInfo> stus = new ArrayList<stuInfo>();//每一個學生的信息作為list集合的每一個元素存儲在list集合中 try { pstmt = conn.prepareStatement("select * from studentinfo"); ResultSet rs = pstmt.executeQuery(); while (rs.next()) { stuInfo stu = new stuInfo(); stu.setId(rs.getInt(1)); stu.setNickname(rs.getString(2)); stu.setTruename(rs.getString(3)); stu.setSex(rs.getByte(4)); if (rs.getDate(5) != null) stu.setbirthday(rs.getDate(5).toString()); stu.setmajor(rs.getString(6)); if (rs.getString(7) != null) stu.setcourse(rs.getString(7).split("&")); if (rs.getString(8) != null) stu.setinterest(rs.getString(8).split("&")); stu.setremark(rs.getString(9)); stus.add(stu); } return stus; } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); return null; } }//查詢單個學生信息 public stuInfo queryStubyID(int id) { // List stus = new ArrayList(); try { pstmt = conn .prepareStatement("select * from studentinfo where id=?"); pstmt.setInt(1, id); ResultSet rs = pstmt.executeQuery(); if (rs.next()) { stuInfo stu = new stuInfo(); stu.setId(rs.getInt(1)); stu.setNickname(rs.getString(2)); stu.setTruename(rs.getString(3)); stu.setSex(rs.getByte(4)); if (rs.getDate(5) != null) stu.setbirthday(rs.getDate(5).toString()); stu.setmajor(rs.getString(6)); if (rs.getString(7) != null) stu.setcourse(rs.getString(7).split("&")); if (rs.getString(8) != null) stu.setinterest(rs.getString(8).split("&")); stu.setremark(rs.getString(9)); // stus.add(stu); return stu; } return null; } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); return null; } } //更新學生信息 public boolean updateStu(stuInfo stu) { try { pstmt = conn .prepareStatement("update studentinfo set Nickname=? , truename=? , sex=? ,birthday=? ," + " major=? ,course=? , interest=?, remark=? where id=?"); pstmt.setString(1, stu.getNickname()); pstmt.setString(2, stu.getTruename()); pstmt.setByte(3, stu.getSex()); pstmt.setString(4, stu.getbirthday()); pstmt.setString(5, stu.getmajor()); pstmt.setString(6, stu.getcourses()); pstmt.setString(7, stu.getinterests()); pstmt.setString(8, stu.getremark()); pstmt.setInt(9, stu.getId()); pstmt.executeUpdate(); return true; } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); return false; } } //刪除學生信息 public Boolean deleteStu(int id) { try { pstmt = conn.prepareStatement("delete from studentinfo where id=?"); pstmt.setInt(1, id); pstmt.executeUpdate(); return true; } catch (Exception e) { e.getStackTrace(); return false; } }} 2.InputStuInfoServlet，添加學生信息的Servlet
package com.servlet; import java.io.IOException;import java.io.PrintWriter;import java.util.Date; import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse; import com.model.stuInfo;import com.service.stuInfoService; public class inputStuInfoServlet extends HttpServlet { /** * Constructor of the object. */ public inputStuInfoServlet() { super(); } /** * Destruction of the servlet. <br> */ public void destroy() { super.destroy(); // Just puts "destroy" string in log // Put your code here } /** * The doGet method of the servlet. <br> * * This method is called when a form has its tag value method equals to get. * * @param request the request send by the client to the server * @param response the response send by the server to the client * @throws ServletException if an error occurred * @throws IOException if an error occurred */ public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doPost(request, response); } /** * The doPost method of the servlet. <br> * * This method is called when a form has its tag value method equals to post. * * @param request the request send by the client to the server * @param response the response send by the server to the client * @throws ServletException if an error occurred * @throws IOException if an error occurred */ public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("utf-8");//get到表單所有的控件的值 String nickname=request.getParameter("nickname"); String truename=request.getParameter("truename"); byte sex=Byte.parseByte(request.getParameter("sex")); String birthday=request.getParameter("birthday"); String major=request.getParameter("major"); System.out.println(major); //String course=request.getParameter("course"); String courses[]=request.getParameterValues("course"); String interests[]=request.getParameterValues("interest"); String remark=request.getParameter("remark"); //放到Javabean中暫時保存 stuInfo stu=new stuInfo(); stu.setNickname(nickname); stu.setTruename(truename); stu.setbirthday(birthday); if(birthday.equals("")) stu.setbirthday(null); if(courses!=null) stu.setcourse(courses); if(interests!=null) stu.setinterest(interests); stu.setremark(remark); stu.setmajor(major); stu.setSex(sex); if(new stuInfoService().addStu(stu))//插入學生數據的方法 response.sendRedirect("../inputStuInfo_success.jsp"); else response.sendRedirect("../inputStuInfo.jsp");//插入數據庫失敗則返回初始輸入頁面 } /** * Initialization of the servlet. <br> * * @throws ServletException if an error occurs */ public void init() throws ServletException { // Put your code here } } 3.stuInfo，保存學生信息的Javabean
package com.model;//Javabean相當于是一個中間件，用于類與類之間，各層之間的中轉數據的一個中轉站public class stuInfo { private int id; private String nickname; private String truename; private byte sex; private String birthday; private String major; private String[] course = { "" }; private String courses = ""; private String[] interest = { "" }; private String interests = ""; private String remark; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getNickname() { return nickname; } public void setNickname(String nickname) { this.nickname = nickname; } public String getTruename() { return truename; } public void setTruename(String truename) { this.truename = truename; } public byte getSex() { return sex; } public void setSex(byte sex) { this.sex = sex; } public String getbirthday() { return birthday; } public void setbirthday(String birthday) { this.birthday = birthday; } public String getmajor() { return major; } public void setmajor(String major) { this.major = major; } public String[] getcourse() { return course; } public void setcourse(String[] course) { this.course = course; } public String getcourses() { if(course!=null) {courses=""; for(int i=0;i<course.length;i++) courses+=course[i]+"&"; } courses=courses.substring(0,courses.length()-1); return courses; } public void setcourses(String courses) { this.courses = courses; } public String[] getinterest() { return interest; } public void setinterest(String[] interest) { this.interest = interest; } public String getinterests() { if(interest!=null) {interests=""; for(int i=0;i<interest.length;i++) interests+=interest[i]+"&"; } interests=interests.substring(0,interests.length()-1); return interests; } public void setinterests(String interests) { this.interests = interests; } public String getremark() { return remark; } public void setremark(String remark) { this.remark = remark; }} 4.DB connect 類
package com.conn; import java.sql.Connection;import java.sql.DriverManager; public class conn { public Connection getCon() { try { Class.forName("com.mysql.jdbc.Driver"); String url = "jdbc:mysql://localhost/Stu_info_System?useUnicode=true&characterEncoding=utf-8"; String user = "root"; String password = "root"; Connection conn = DriverManager.getConnection(url, user, password); System.out.println(conn.getMetaData().getURL()); return conn; } catch (Exception e) { e.printStackTrace(); return null; } } }
