更改springboot启动方式
让App类继承AbstractJavaFxApplicationSupport，注意main方法。
public class App extends AbstractJavaFxApplicationSupport{
public static void main(String[] args) {
launch(args);
}
@Bean
public Gson gson() {
return new Gson();
}
@Override
public void start(Stage stage) throws IOException {
stage.setTitle(R.title);
BorderPane root = new BorderPane();
VBox vBox = new VBox();
HBox hBox = new HBox();
Label label = new Label();
label.setText(R.sysTitle+"已经启动");
label.setTextFill(Paint.valueOf("Green"));
Label labelUrl = new Label();
String port = getBaseCfgFromProperties();
String labelUrlStr = "127.0.0.1:"+port;
labelUrl.setOnMouseClicked(event -> {
CommonUtil.openUrl(labelUrlStr);
});
labelUrl.setText(labelUrlStr);
labelUrl.setTextFill(Paint.valueOf("Red"));
labelUrl.setStyle("-fx-background-color: #7ee;");
hBox.getChildren().addAll(label,labelUrl);
hBox.setAlignment(Pos.BASELINE_CENTER);
hBox.setPrefHeight(25);
hBox.setSpacing(5);
//---------------------------
HBox hBox1 = new HBox();
Label label1 = new Label();
label1.setText(R.readme);
label1.setTextFill(Paint.valueOf("Gray"));
hBox1.getChildren().add(label1);
hBox1.setAlignment(Pos.BASELINE_CENTER);
hBox1.setPrefHeight(25);
//---------------------------
vBox.getChildren().addAll(hBox,hBox1);
root.setCenter(vBox);
stage.setScene(new Scene(root,300,50));
Image icon = new Image(R.ICON, 32, 32, false, false);
stage.getIcons().add(icon);
MySystemTray.getInstance(stage);
stage.show();
}
public static String getBaseCfgFromProperties() throws IOException {
InputStream props = App.class.getClassLoader().getResourceAsStream("application.properties");
Properties properties = new Properties();
properties.load(props);
return (String) properties.get("server.port");
}
}

通过托盘直接使用默认浏览器打开默认网页
这样做可以直接让用户看到程序界面，很利好那些对软件不太数据的用户。
public class CommonUtil {
public static void openUrl(String url){
try {
String stmt = "start explorer http://"+url;
String[] command = {"cmd", "/c", stmt};
Runtime runtime = Runtime.getRuntime();
runtime.exec(command);
} catch (IOException e) {
e.printStackTrace();
}
}
}
辅助控制程序增加系统消息推送功能
通过托盘退出程序效果。只找到awt与系统交互的工具类，如下图所示。

import javax.imageio.ImageIO;
import java.awt.*;
import java.io.IOException;
import java.io.InputStream;
