毕业设计：基于SSM框架的学生实习管理系统

系统设计

主要功能点

高校实习管理系统主要解决各大高校学生暑假实习/寒假实习等过程管理难的问题，提升学校、老师和学生、企业之间的联系，避免学生因实习任务而感到为难，解决学校和老师无法实时感知到学生的实习情况，无法了解到学生的实习过程，无法对实习结果进行评分等问题，提升企业和学校的沟通，及时发现学生存在的问题，优化实习安排，更好的帮助学生尽快的融入社会。

高校实习管理系统的主要需求是提供给学生以及老师管理学生实习过程的系统，方便师生管理自己的实习计划，目前系统分为教师、企业以及学生三种角色，以及固定的管理员角色。其中教师负责制定和发布学习计划，发布学习任务或者管理学生的日记等，评价学生的实习情况以及查看统计分析。企业负责根据教师发布的学习计划，提供相应的实习岗位供学生选择，也可以对学生的岗位实习情况进行评价。学生负责选择适合自己的学习计划以及学习岗位，并按时填写完成情况和周报等。管理员角色负责管理用户信息、角色信息、角色权限、学生管理，教师信息管理、企业信息管理等等。

主要功能如下：

企业角色功能模块
- 注册：注册企业账户

登录：登录企业账户
- 查看实习计划：查看教师发布的实习计划
实习岗位管理：对实习岗位进行新增，修改，删除，查询操作。
- 实习任务管理：对实习任务进行新增，修改，删除，查询操作。
任务完成情况管理：可以查看任务完成情况，并予以评价。

教师角色功能模块

分类规则标准，数据接口设计通用。
后台数据可以快速检索。进行查询、增加、删除、修改、统计等操作。
系统安全包含用户安全，数据安全，验证技术可靠合理通用，对具体操作分角色分权限，保证数据的安全可靠。

技术实现

涉及的主要技术点

基于SSM思想实现的SpringBoot框架，用于提供web服务，SpringBoot是在SpringMvc的基础上提出了约定大于配置的思想，以约定的形式省去了SpringMvc的许多配置项，这些配置项可以以约定好的名称以类似插件的方式接入到系统中。
MyBatis框架，MyBatis 是一款优秀的持久层框架，它支持定制化 SQL、存储过程以及高级映射。MyBatis 避免了几乎所有的 JDBC 代码和手动设置参数以及获取结果集。MyBatis 可以使用简单的 XML 或注解来配置和映射原生信息，将接口和 Java 的 POJOs(Plain Ordinary Java Object,普通的 Java对象)映射成数据库中的记录。
Mysql数据库，MySQL 是最流行的关系型数据库管理系统，在 WEB 应用方面 MySQL 是最好的 RDBMS(Relational Database Management System：关系数据库管理系统)应用软件之一
Shiro框架，Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理。使用Shiro的易于理解的API,您可以快速、轻松地获得任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序。
Redis缓存数据库，Redis 是一个开源的使用 ANSI C 语言编写、遵守 BSD 协议、支持网络、可基于内存、分布式、可选持久性的键值对(Key-Value)存储数据库，并提供多种语言的 API。Redis 通常被称为数据结构服务器，因为值（value）可以是字符串(String)、哈希(Hash)、列表(list)、集合(sets)和有序集合(sorted sets)等类型。
Layui框架，一个优秀的前端UI框架，可以帮你快速建立增删改查等基础前端架构，https://layuion.com/
Jquery，Jquery是一个快速、简洁的JavaScript框架，是继Prototype之后又一个优秀的JavaScript代码库（框架）于2006年1月由[John Resig](https://baike.baidu.com/item/John Resig/6336344)发布。jQuery设计的宗旨是“write Less，Do More”，即倡导写更少的代码，做更多的事情。它封装JavaScript常用的功能代码，提供一种简便的JavaScript设计模式，优化HTML文档操作、事件处理、动画设计和Ajax交互。
ECharts，ECharts是一款基于JavaScript的数据可视化图表库，提供直观，生动，可交互，可个性化定制的数据可视化图表。ECharts最初由百度团队开源，并于2018年初捐赠给Apache基金会，成为ASF孵化级项目

设计思路

本系统按照角色划分为管理员、学生、教师、企业，教师角色负责管理实习计划，企业负责管理实习岗位，学生角色可以选择实习计划、实习岗位等加入，并且填写相关的任务反馈，管理员角色负责查看整体的统计分析，对整体学生的实习过程进行管理。

代码实现

本系统采用Java语言编写，主要是基于Mvc的架构模式实现，按照模块可以划分为控制层、服务层、持久层三大块

控制层

控制层主要是基于Springboot提供Web接口，本系统所有数据接口均采用JSON的方式进行数据交互，页面映射采用ModelAndView的方式处理，只映射页面不传递数据，命名方式也是按照业务划分的，比如实习计划管理对应的控制层代码文件命名为PlanController

控制层代码如下所示，控制层会按照统一的状态码返回信息，遵循Http状态码的规则，默认200为正常请求，异常请求会返回msg作为提示信息。部分代码实现如下所示

服务层

服务层提供具体业务功能的实现，比如学院管理，查询学院信息进行分页处理时，可能要先查询总数，然后按照总数和每页数量进行分页查询所需的数据，在服务层会对控制层的请求和操作数据库的多次动作进行包装，例如查询出某条数据，但该数据中信息需要进行编码-显示名称的转化时（如数据库存储的性别数据是0和1，页面上显示需要展示成男和女），命名方式也是按照业务划分的，服务层部分代码如下所示

持久层

持久层负责与数据库交互，mybatis正是在这一层发挥其作用，通过其ORM框架的能力连接起java代码和数据库SQL执行，示例代码如下

package com.crk.shixiguanli.dao;import com.crk.shixiguanli.entity.Plan;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;import java.util.HashMap;
import java.util.List;@Repository
