JavaFX简单音乐播放器

最近用javaFX写了一个音乐播放器，用swing感觉自定义界面太麻烦了所以用了 javaFX 因为时间关系我就只学了自定义界面和音乐的触发事件，小白一枚写的代码可能会不规范。请大家谅解

然后用到了数据库的方式存放歌曲的地址，因为我这个萌新还没有学用网络爬取歌曲，所以歌曲存放在本地

哇，我一直以为//# java这个才是标题搞了好久一直提示我请勿使用默认标题搞了好久才知道
这个才是标题（捂脸）

下面是效果图

下面是代码

代码变量初始化

public class Main extends Application{public static void main(String[] args) {launch(args);
}Music_Dao music_Dao =new Music_Dao();//这个是dao层下的包等会调用数据库时用到的
Media media;
MediaPlayer mediaPlayer;
HashMap<Integer, String> hashMap_song;
help help_method;
ObservableList<String> observableList;//一个存放歌曲地址的一个集合
int flage=0;//歌曲列表的索引
//用来拖动
double x=0;//定义一个x用来存放鼠标在窗口的当前x轴位置
double y=0;//定义一个y用来存放鼠标在窗口的当前y轴位置
boolean max_is=true;//用来判断当前窗口是否是最大化状态 true：是  false：否
boolean is_play=true;//判断一个歌曲是否真正播放
boolean is_mouse=false;//用来判断鼠标是否在进度条上
Label setbackgroud;//用来存放播放时用的模糊图片
Slider slider;//以下是歌曲的信息  名字、演唱者、歌曲类型、歌曲图片
Label song_name;
Label song_songer;
Label song_type;
Label song_image;

下面是重写Application类中的 start()方法

下面是一些重复的代码我就把它装在方法里面了

public void getsongname() throws SQLException {//使用数据库添加数据List<Music_Bean> list_music=music_Dao.select();for(Music_Bean music:list_music) {observableList.add(music.getName());}
}
//查询数据库的歌曲列表 并放进list 里面
public void get_song_map() throws SQLException {List<Music_Bean> list_music=music_Dao.select();for(Music_Bean music:list_music) {System.out.println(music.getId()-1+" "+music.getUrl());hashMap_song.put(music.getId()-1, music.getUrl());}System.out.println(hashMap_song);
}
//用来加载歌曲的信息，歌曲的image\name\type\time
public void SliderListener() {mediaPlayer.setOnPlaying(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubslider.setMin(0.0);slider.setMax(mediaPlayer.getTotalDuration().toSeconds());mediaPlayer.currentTimeProperty().addListener(new ChangeListener<Duration>() {@Overridepublic void changed(ObservableValue<? extends Duration> observable, Duration oldValue,Duration newValue) {// TODO Auto-generated method stubif(is_mouse==false)slider.setValue(newValue.toSeconds());}});ObservableMap<String, Object> map =media.getMetadata();Image  songimage=(Image)map.get("image");ImageView songimageview=new ImageView(songimage);songimageview.setFitWidth(347/2);songimageview.setFitHeight(350/2);song_image.setGraphic(songimageview);song_name.setText(map.get("title").toString());song_name.setFont(new Font("Microsoft Yahei",25));song_name.setStyle("-fx-font-weight: bold;");song_name.setTextFill(Paint.valueOf("#962aec"));song_songer.setText("演唱者："+map.get("artist").toString());song_songer.setFont(new Font("STHeiti", 15));song_songer.setTextFill(Paint.valueOf("#dd8fe5"));song_type.setText("歌曲类型："+map.get("genre").toString());song_type.setFont(new Font("STHeiti", 15));song_type.setTextFill(Paint.valueOf("#dd8fe5"));}});
}
public void SetbackgroudAndsongImage() {Image setbackgound=new Image("image/背景副.png");setbackgroud.setGraphic(new ImageView(setbackgound));
}
}

以上就是主界面的全部代码了

下面是数据库的连接工具类

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;public class Dbhelper {private static final String DRIVERNAME="com.mysql.jdbc.Driver";
private static final String URL="jdbc:mysql://localhost:3306/music_library";
private static final String USERNAME="root";
private static final String PASSWORD="123456";
static {try {Class.forName(DRIVERNAME);} catch (ClassNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();}
}
public static Connection getconnetion() throws SQLException {return DriverManager.getConnection(URL,USERNAME,PASSWORD);
}
public static void close(ResultSet result,PreparedStatement ps,Connection conn) throws SQLException {if(result!=null)result.close();if(ps!=null)ps.close();if(conn!=null)conn.close();
}
}

在调用数据库的连接类得到数据库中的歌曲名字与地址

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;import bean.Music_Bean;
import utils.Dbhelper;public class Music_Dao {//查询public List<Music_Bean> select() throws SQLException{Connection conn=Dbhelper.getconnetion();String sql="SELECT * FROM music";PreparedStatement ps=conn.prepareStatement(sql);ResultSet result=ps.executeQuery();List<Music_Bean> list=new ArrayList<Music_Bean>();while(result.next()) {Music_Bean music=new Music_Bean();music.setId(result.getInt(1));music.setName(result.getString(2));music.setUrl(result.getString(3));list.add(music);}return list;}
}

Music_Bean类

public class Music_Bean {private int id;
private String name;
public String getName() {return name;
}
public void setName(String name) {this.name = name;
}
private String url;
public int getId() {return id;
}
public void setId(int id) {this.id = id;
}
public String getUrl() {return url;
}
public void setUrl(String url) {this.url = url;
}
}

然后这是我自己建立的包

存放歌曲的包

以上就是这个项目的全部代码了
做的不好的地方请各位大神指出，后期我还会对这个播放器添加一下功能
