【JavaWeb】将普通项目变成ssm项目 01_java

最近学习完ssm框架就打算拿之前做过的老的学生成绩管理系统来练练手。

目标

导入ssm整合的所有jar包
在项目里打好ssm框架
创建好需要的配置文件
建立数据库
在项目组创建需要的持久化类

导入ssm整合的所有jar包

将如图所示的所有jar包放入WEB-INF/lib文件夹下

在项目里打好ssm框架

com.stuos.controller:放控制层代码
com.stuos.dao:放dao层代码
com.stuos.po:放持久化类
com.stuos.service:放服务层接口代码
com.stuos.service.impl:放服务层的接口实现类
config:放配置文件

创建好需要的配置文件

applicationContext.xml（spring的配置文件）

建立数据库

使用之前系统数据库的sql文件重建数据库
这里使用navicat

在项目组创建需要的持久化类

根据数据库创建持久化类

课程类

package com.stuos.po;
/*
 * 课程类
 * 
 * */
public class Course {
	
	private String courseId;//课程号
	private String courseName;//课程名称
	private String teaId;//授课教师
	
	public Course() {
		
	}
	public Course(String id,String name,String teaid) {
		this.courseId = id;
		this.courseName = name;
		this.teaId = teaid;
	}
	public String getCourseId() {
		return courseId;
	}
	public void setCourseId(String courseId) {
		this.courseId = courseId;
	}
	public String getCourseName() {
		return courseName;
	}
	public void setCourseName(String courseName) {
		this.courseName = courseName;
	}
	public String getTeaId() {
		return teaId;
	}
	public void setTeaId(String teaId) {
		this.teaId = teaId;
	}
	
}

修改成绩类

package com.stuos.po;
/*
 * 修改成绩请求类
 * 
 * */
public class ModifyScore {

	private int Id;//申请序号，主键
	private String teaId;//申请老师
	private String stuId;//修改的学生的学号
	private String courseId;//修改的课程号
	private int newScore;//新分数
	private int flag1;//秘书处理结果
	private int flag2;//专业负责人处理结果
	
	public ModifyScore() {
		
	}
	public ModifyScore(String teaid,String stuid,String courseid,int newscore) {
		this.teaId = teaid;
		this.stuId = stuid;
		this.courseId = courseid;
		this.newScore = newscore;
		this.flag1 = 0;
		this.flag2 = 0;
	}
	public int getId() {
		return Id;
	}
	public void setId(int id) {
		Id = id;
	}
	public String getTeaId() {
		return teaId;
	}
	public void setTeaId(String teaId) {
		this.teaId = teaId;
	}
	public String getStuId() {
		return stuId;
	}
	public void setStuId(String stuId) {
		this.stuId = stuId;
	}
	public String getCourseId() {
		return courseId;
	}
	public void setCourseId(String courseId) {
		this.courseId = courseId;
	}
	public int getNewScore() {
		return newScore;
	}
	public void setNewScore(int newScore) {
		this.newScore = newScore;
	}
	public int getFlag1() {
		return flag1;
	}
	public void setFlag1(int flag1) {
		this.flag1 = flag1;
	}
	public int getFlag2() {
		return flag2;
	}
	public void setFlag2(int flag2) {
		this.flag2 = flag2;
	}
	
}

成绩类

package com.stuos.po;
/*
 * 成绩类
 * 
 * */
public class Score {
	
	private int Id;//列表序号，主键
	private String stuId;//学生学号
	private String courseId;//课程号
	private int score;//学生成绩
	
	public Score() {
		
	}
	public Score(String stuid,String courseid,int s) {
		this.stuId = stuid;
		this.courseId = courseid;
		this.score = s;
	}
	public int getId() {
		return Id;
	}
	public void setId(int id) {
		Id = id;
	}
	public String getStuId() {
		return stuId;
	}
	public void setStuId(String stuId) {
		this.stuId = stuId;
	}
	public String getCourseId() {
		return courseId;
	}
	public void setCourseId(String courseId) {
		this.courseId = courseId;
	}
	public int getScore() {
		return score;
	}
	public void setScore(int score) {
		this.score = score;
	}
	
}

用户类

package com.stuos.po;



/*
 * 用户类
 * 
 * */
public class User {
	private String userId;//用户身份标识符：1为管理员，2为专业负责人，3为班主任，4为教师，5为辅导员，6为秘书，7为学生
	private String userAcc;//用户账号
	private String userPwd;//用户密码
	private String userName;//用户姓名
	private int userAge;//用户年龄
	private String userSex;//用户性别


	public User(String id,String acc,String pwd) {//可以直接赋值的构造函数
		this.userId = id;
		this.userAcc = acc;
		this.userPwd = pwd;
		this.userName = "";
		this.userAge = 0;
		this.userSex = "";
	}
	public User() {
		
	}
	
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public int getUserAge() {
		return userAge;
	}
	public void setUserAge(int userAge) {
		this.userAge = userAge;
	}
	public String getUserSex() {
		return userSex;
	}
	public void setUserSex(String userSex) {
		this.userSex = userSex;
	}
	public String getUserId() {
		return userId;
	}
	public void setUserId(String userId) {
		this.userId = userId;
	}
	public String getUserAcc() {
		return userAcc;
	}
	public void setUserAcc(String userAcc) {
		this.userAcc = userAcc;
	}
	public String getUserPwd() {
		return userPwd;
	}
	public void setUserPwd(String userPwd) {
		this.userPwd = userPwd;
	}
	
	
	
}
