學生成績管理系統/學生信息管理系統
接畢業設計 + vx: likeyou9525
基於ssm框架開發的，使用Eclipse，連接MySQL數據庫，存儲學生的身份信息、成績、課程信息，管理員的身份信息。
部分效果圖在最下面。
一、數據庫環境搭建
創建user表
CREATE TABLE `user` (
`name` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`password` varchar(20) DEFAULT NULL,
PRIMARY KEY (`name`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
創建student表
CREATE TABLE `student` (
`studentId` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`studentName` varchar(40) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`studentSex` varchar(4) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`studentAge` varchar(2) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT '',
`studentBifthday` date DEFAULT NULL,
`studentDept` varchar(40) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`studentMajor` varchar(40) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`studentClassId` varchar(40) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`studentCellPhone` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`studentpad` varchar(20) DEFAULT '123456',
PRIMARY KEY (`studentId`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
創建score表
CREATE TABLE `score` (
`id` int NOT NULL AUTO_INCREMENT,
`studentId` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '學號',
`courseId` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '課程號',
`score` varchar(20) NOT NULL COMMENT '成績',
PRIMARY KEY (`id`,`studentId`,`courseId`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=173 DEFAULT CHARSET=utf8;
創建course表
CREATE TABLE `course` (
`id` int NOT NULL AUTO_INCREMENT,
`courseId` varchar(10) NOT NULL COMMENT '課程號',
`courseName` varchar(60) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '課程名',
`schoolYear` varchar(255) NOT NULL COMMENT '學年',
`creditHour` varchar(5) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '學分',
`teacher` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '任課老師',
PRIMARY KEY (`id`,`courseId`,`courseName`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=34 DEFAULT CHARSET=utf8;
二、ssm框架搭建
引入Spring框架所需要的包，Mybatis框架所需要的包，Mybatis與Spring整合的中間包，數據源驅動包，DBCP數據源和連接池需要的包，Spring MVC框架所需要的包。
在項目的src目錄下創建log4j.properties文件
# Global logging configuration
log4j.rootLogger=ERROR, stdout
# MyBatis logging configuration...
log4j.logger.com.itheima=DEBUG
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
在src目錄下創建db.properties 文件。編寫數據庫相關屬性和對應值。
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/studentinfo?serverTimezone=UTC
jdbc.username=root
jdbc.password=123456
jdbc.maxTotal=30
jdbc.maxIdle=10
jdbc.initialSize=5
在src目錄下，創建Spring的配置文件applicationContext.xml

創建service包

分頁
在src目錄下創建com.chen.untils包，並創建PageBean類。
package com.chen.untils;
import java.util.List;
public class PageBean<T> {
private int currPage;//當前頁數
private int pageSize;//每頁顯示的記錄數
private int totalCount;//總記錄數
private int totalPage;//總頁數
private String id;
private List<T> lists;//每頁的顯示的數據
public PageBean() {
super();
}
public int getCurrPage() {
return currPage;
}
public void setCurrPage(int currPage) {
this.currPage = currPage;
}
public int getPageSize() {
return pageSize;
}
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
public int getTotalCount() {
return totalCount;
}
public void setTotalCount(int totalCount) {
this.totalCount = totalCount;
}
public int getTotalPage() {
return totalPage;
}
public void setTotalPage(int totalPage) {
this.totalPage = totalPage;
}
public List<T> getLists() {
return lists;
}
public void setLists(List<T> lists) {
this.lists = lists;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
三、前端jsp頁面編碼
在WebContent目錄下，創建名為jsp的文件夾，然后在文件中創建如下頁面。
登錄頁面（ login.jsp ）
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<head>
<meta charset="utf-8">
<title>登陸頁面</title>
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/css/stylelogin.css">
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/css/iconfont.css">
<script language="JavaScript">
window.onload=init;
function init() {
var pop = "${requestScope.msg}";
if(pop != ""){
alert(pop);
}
}
</script>
</head>
<body>
<div id="maxbox">
<h3>學生成績管理系統</h3>

四、效果圖
管理員登錄效果圖
五、總結
該學生成績管理系統總體說來基本完成了增刪改查，登錄分為學生登錄和學生管理員登錄，學生登錄只能查看自己的個人信息、成績信息、課程信息和修改自己的登錄密碼。學生管理員登錄可以對學生信息、課程信息和成績信息進行增刪改查。數據庫的設計方面，建有學生表、管理員表、課程表、成績表。
剛拿到選題的時候，自己還是有蠻多想法的，但是在一步步實踐中放棄了，因為自己學到的技術有限，還不足以讓我能做出一個功能很豐富的系統，這恰好是我學習的動力，爭取下次做出一個功能完整的系統。在此也特別感謝王佩同學不厭其煩的為我解決一個一個又一個的問題。
