Java综合课设：公园管理系统的简单实现 Java + MySQL + Swing

写了蛮久的综合课设大作业，今天分享一下下，我们需要创建的是一个maven项目，该作业使用到了 Java + MySQL + GUI 实现，具体可见下面。

一、展示：

登陆界面：

主界面：

添加界面：

修改界面：

二、目录：

创建的maven项目初始样子：

创建好包、类之后：

三、代码:

Tourist：

packageClass;//游客类publicclassTourist{String id;String name;String age;String gender;String sort;String inTime;String outTime;publicTourist(String id,String name,String age,String gender,String sort,String inTime,String outTime){this.id = id;this.name = name;this.age = age;this.gender = gender;this.sort = sort;this.inTime = inTime;this.outTime = outTime;}publicTourist(String name,String age,String gender,String sort,String inTime,String outTime){this.id = id;this.name = name;this.age = age;this.gender = gender;this.sort = sort;this.inTime = inTime;this.outTime = outTime;}publicStringgetId(){return id;}publicStringgetName(){return name;}publicStringgetAge(){return age;}publicStringgetGender(){return gender;}publicStringgetSort(){return sort;}publicStringgetInTime(){return inTime;}publicStringgetOutTime(){return outTime;}}

AddView ：

        touristOperate =newTouristOperate(this);

        nameLab.setPreferredSize(newDimension(80,30));
        jPanel.add(nameLab);
        nameTxt.setPreferredSize(newDimension(200,30));

        r.setHorizontalAlignment(JLabel.CENTER);setDefaultRenderer(Object.class,r);}}

**LoginView：登录面板里面右上角有一个小图标，是通过

URL url = LoginView.class.getClassLoader().getResource("qq.jpg")

实现的，图片我没给，可以选择自己喜欢的一张拖进resources 包下，然后更改对应路径名就可以了。**
