發(fā)布時間：2023/12/14 windows 31 豆豆

生活随笔收集整理的這篇文章主要介紹了毕业设计：基于SSM框架的学生实习管理系统小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

系統(tǒng)設(shè)計

主要功能點(diǎn)

? 高校實(shí)習(xí)管理系統(tǒng)主要解決各大高校學(xué)生暑假實(shí)習(xí)/寒假實(shí)習(xí)等過程管理難的問題，提升學(xué)校、老師和學(xué)生、企業(yè)之間的聯(lián)系，避免學(xué)生因?qū)嵙?xí)任務(wù)而感到為難，解決學(xué)校和老師無法實(shí)時感知到學(xué)生的實(shí)習(xí)情況，無法了解到學(xué)生的實(shí)習(xí)過程，無法對實(shí)習(xí)結(jié)果進(jìn)行評分等問題，提升企業(yè)和學(xué)校的溝通，及時發(fā)現(xiàn)學(xué)生存在的問題，優(yōu)化實(shí)習(xí)安排，更好的幫助學(xué)生盡快的融入社會。

? 高校實(shí)習(xí)管理系統(tǒng)的主要需求是提供給學(xué)生以及老師管理學(xué)生實(shí)習(xí)過程的系統(tǒng)，方便師生管理自己的實(shí)習(xí)計劃，目前系統(tǒng)分為教師、企業(yè)以及學(xué)生三種角色，以及固定的管理員角色。其中教師負(fù)責(zé)制定和發(fā)布學(xué)習(xí)計劃，發(fā)布學(xué)習(xí)任務(wù)或者管理學(xué)生的日記等，評價學(xué)生的實(shí)習(xí)情況以及查看統(tǒng)計分析。企業(yè)負(fù)責(zé)根據(jù)教師發(fā)布的學(xué)習(xí)計劃，提供相應(yīng)的實(shí)習(xí)崗位供學(xué)生選擇，也可以對學(xué)生的崗位實(shí)習(xí)情況進(jìn)行評價。學(xué)生負(fù)責(zé)選擇適合自己的學(xué)習(xí)計劃以及學(xué)習(xí)崗位，并按時填寫完成情況和周報等。管理員角色負(fù)責(zé)管理用戶信息、角色信息、角色權(quán)限、學(xué)生管理，教師信息管理、企業(yè)信息管理等等。

主要功能如下：

擬解決的主要問題

前端展示分類合理，內(nèi)容實(shí)用，主題突出；后臺服務(wù)設(shè)計思路清晰，通用性強(qiáng)。

分類規(guī)則標(biāo)準(zhǔn)，數(shù)據(jù)接口設(shè)計通用。

后臺數(shù)據(jù)可以快速檢索。進(jìn)行查詢、增加、刪除、修改、統(tǒng)計等操作。

系統(tǒng)安全包含用戶安全，數(shù)據(jù)安全，驗(yàn)證技術(shù)可靠合理通用，對具體操作分角色分權(quán)限，保證數(shù)據(jù)的安全可靠。

技術(shù)實(shí)現(xiàn)

涉及的主要技術(shù)點(diǎn)

基于SSM思想實(shí)現(xiàn)的SpringBoot框架，用于提供web服務(wù)，SpringBoot是在SpringMvc的基礎(chǔ)上提出了約定大于配置的思想，以約定的形式省去了SpringMvc的許多配置項(xiàng)，這些配置項(xiàng)可以以約定好的名稱以類似插件的方式接入到系統(tǒng)中。

MyBatis框架，MyBatis 是一款優(yōu)秀的持久層框架，它支持定制化 SQL、存儲過程以及高級映射。MyBatis 避免了幾乎所有的 JDBC 代碼和手動設(shè)置參數(shù)以及獲取結(jié)果集。MyBatis 可以使用簡單的 XML 或注解來配置和映射原生信息，將接口和 Java 的 POJOs(Plain Ordinary Java Object,普通的 Java對象)映射成數(shù)據(jù)庫中的記錄。

Mysql數(shù)據(jù)庫，MySQL 是最流行的關(guān)系型數(shù)據(jù)庫管理系統(tǒng)，在 WEB 應(yīng)用方面 MySQL 是最好的 RDBMS(Relational Database Management System：關(guān)系數(shù)據(jù)庫管理系統(tǒng))應(yīng)用軟件之一

Shiro框架，Apache Shiro是一個強(qiáng)大且易用的Java安全框架,執(zhí)行身份驗(yàn)證、授權(quán)、密碼和會話管理。使用Shiro的易于理解的API,您可以快速、輕松地獲得任何應(yīng)用程序,從最小的移動應(yīng)用程序到最大的網(wǎng)絡(luò)和企業(yè)應(yīng)用程序。

Redis緩存數(shù)據(jù)庫，Redis 是一個開源的使用 ANSI C 語言編寫、遵守 BSD 協(xié)議、支持網(wǎng)絡(luò)、可基于內(nèi)存、分布式、可選持久性的鍵值對(Key-Value)存儲數(shù)據(jù)庫，并提供多種語言的 API。Redis 通常被稱為數(shù)據(jù)結(jié)構(gòu)服務(wù)器，因?yàn)橹?#xff08;value）可以是字符串(String)、哈希(Hash)、列表(list)、集合(sets)和有序集合(sorted sets)等類型。

Layui框架，一個優(yōu)秀的前端UI框架，可以幫你快速建立增刪改查等基礎(chǔ)前端架構(gòu)，https://layuion.com/

Jquery，Jquery是一個快速、簡潔的JavaScript框架，是繼Prototype之后又一個優(yōu)秀的JavaScript代碼庫（框架）于2006年1月由[John Resig](https://baike.baidu.com/item/John Resig/6336344)發(fā)布。jQuery設(shè)計的宗旨是“write Less，Do More”，即倡導(dǎo)寫更少的代碼，做更多的事情。它封裝JavaScript常用的功能代碼，提供一種簡便的JavaScript設(shè)計模式，優(yōu)化HTML文檔操作、事件處理、動畫設(shè)計和Ajax交互。

ECharts，ECharts是一款基于JavaScript的數(shù)據(jù)可視化圖表庫，提供直觀，生動，可交互，可個性化定制的數(shù)據(jù)可視化圖表。ECharts最初由百度團(tuán)隊開源，并于2018年初捐贈給Apache基金會，成為ASF孵化級項(xiàng)目

設(shè)計思路

本系統(tǒng)按照角色劃分為管理員、學(xué)生、教師、企業(yè)，教師角色負(fù)責(zé)管理實(shí)習(xí)計劃，企業(yè)負(fù)責(zé)管理實(shí)習(xí)崗位，學(xué)生角色可以選擇實(shí)習(xí)計劃、實(shí)習(xí)崗位等加入，并且填寫相關(guān)的任務(wù)反饋，管理員角色負(fù)責(zé)查看整體的統(tǒng)計分析，對整體學(xué)生的實(shí)習(xí)過程進(jìn)行管理。

代碼實(shí)現(xiàn)

本系統(tǒng)采用Java語言編寫，主要是基于Mvc的架構(gòu)模式實(shí)現(xiàn)，按照模塊可以劃分為控制層、服務(wù)層、持久層三大塊

控制層

控制層主要是基于Springboot提供Web接口，本系統(tǒng)所有數(shù)據(jù)接口均采用JSON的方式進(jìn)行數(shù)據(jù)交互，頁面映射采用ModelAndView的方式處理，只映射頁面不傳遞數(shù)據(jù)，命名方式也是按照業(yè)務(wù)劃分的，比如實(shí)習(xí)計劃管理對應(yīng)的控制層代碼文件命名為PlanController

控制層代碼如下所示，控制層會按照統(tǒng)一的狀態(tài)碼返回信息，遵循Http狀態(tài)碼的規(guī)則，默認(rèn)200為正常請求，異常請求會返回msg作為提示信息。部分代碼實(shí)現(xiàn)如下所示

服務(wù)層

服務(wù)層提供具體業(yè)務(wù)功能的實(shí)現(xiàn)，比如學(xué)院管理，查詢學(xué)院信息進(jìn)行分頁處理時，可能要先查詢總數(shù)，然后按照總數(shù)和每頁數(shù)量進(jìn)行分頁查詢所需的數(shù)據(jù)，在服務(wù)層會對控制層的請求和操作數(shù)據(jù)庫的多次動作進(jìn)行包裝，例如查詢出某條數(shù)據(jù)，但該數(shù)據(jù)中信息需要進(jìn)行編碼-顯示名稱的轉(zhuǎn)化時（如數(shù)據(jù)庫存儲的性別數(shù)據(jù)是0和1，頁面上顯示需要展示成男和女），命名方式也是按照業(yè)務(wù)劃分的，服務(wù)層部分代碼如下所示

持久層

持久層負(fù)責(zé)與數(shù)據(jù)庫交互，mybatis正是在這一層發(fā)揮其作用，通過其ORM框架的能力連接起java代碼和數(shù)據(jù)庫SQL執(zhí)行，示例代碼如下
