Java学生管理系统项目案例

分代码如下

package com.student.util;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DbUtil {
private String dbUrl="jdbc:mysql://localhost:3306/db_student";
private String user="root";
private String password="123456";
private String jdbcName="com.mysql.jdbc.Driver";
public Connection getCon() throws Exception{
Class.forName(jdbcName);
Connection con=DriverManager.getConnection(dbUrl, user, password);
return con;
}
public void close(Connection con)throws Exception{
if(con!=null){
con.close();
}
}
public static void main(String[] args){
Connection con=null;
try {
con = new DbUtil().getCon();
System.out.println(con);
} catch (Exception e) {
e.printStackTrace();
}finally{
if(con!=null){
try {
con.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}
}

package com.student.model;

public class Student {
private int id;
private String studentnumber;
private String name;
private String birthday;
private String nativeplace;
private int classid;
private String studentremark;

public Student() {
super();
}

public Student(String studentnumber, String name, String birthday,
String nativeplace, int classid, String studentremark) {
super();
this.studentnumber = studentnumber;
this.name = name;
this.birthday = birthday;
this.nativeplace = nativeplace;
this.classid = classid;
this.studentremark = studentremark;
}

public Student(int id, String studentnumber, String name, String birthday,
String nativeplace, int classid, String studentremark) {
super();
this.id = id;
this.studentnumber = studentnumber;
this.name = name;
this.birthday = birthday;
this.nativeplace = nativeplace;
this.classid = classid;
this.studentremark = studentremark;
}

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public String getStudentnumber() {
return studentnumber;
}

public void setStudentnumber(String studentnumber) {
this.studentnumber = studentnumber;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getBirthday() {
return birthday;
}

public void setBirthday(String birthday) {
this.birthday = birthday;
}

public String getNativeplace() {
return nativeplace;
}

public void setNativeplace(String nativeplace) {
this.nativeplace = nativeplace;
}

public int getClassid() {
return classid;
}

public void setClassid(int classid) {
this.classid = classid;
}

public String getStudentremark() {
return studentremark;
}

public void setStudentremark(String studentremark) {
this.studentremark = studentremark;
}

}
