（四）创建基于maven的javaFX+springboot项目，用户界面与后台逻辑分离方式

下面来介绍创建maven的javafx+springboot项目，基于用户界面与后天逻辑分离的方式，用户界面使用fxml文件来常见，类似于jsp，可以引入css文件修饰界面

maven依赖

        <dependency>
            <groupid>org.springframework.boot</groupid>
            <artifactid>spring-boot-starter-actuator</artifactid>
            <version>${spring.boot.version}</version>
        </dependency>
        <dependency>
            <groupid>org.springframework.boot</groupid>
            <artifactid>spring-boot-starter</artifactid>
            <version>${spring.boot.version}</version>
        </dependency>
        <dependency>
            <groupid>de.roskenet</groupid>
            <artifactid>springboot-javafx-support</artifactid>
            <version>${springboot-javafx-support.version}</version>
        </dependency>    

• 创建login.fxml文件，将文件放入resources下，因为springboot默认加载的资源为resources

<?xml version="1.0" encoding="utf-8"?>

<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.text.*?>

<anchorpane id="anchorpane" maxheight="-infinity" maxwidth="-infinity" minheight="-infinity" minwidth="-infinity"
            prefheight="588.0" prefwidth="802.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2"
            fx:controller="com.dome.controller.logincontroller">
  <children>
    <hbox layoutx="122.0" layouty="108.0" prefheight="372.0" prefwidth="526.0">
      <children>
        <label alignment="center" contentdisplay="center" prefheight="30.0" prefwidth="70.0" text="用户名" textalignment="left">
          <font>
            <font size="18.0" fx:id="x1" />
          </font>
          <hbox.margin>
            <insets bottom="10.0" left="50.0" right="10.0" top="100.0" />
          </hbox.margin>
        </label>
        <textfield fx:id="username" id="username" prefheight="30.0" prefwidth="200.0">
          <hbox.margin>
            <insets bottom="10.0" right="10.0" top="100.0" />
          </hbox.margin>
        </textfield>
        <label alignment="center" contentdisplay="center" font="$x1" prefheight="30.0" prefwidth="70.0" text="密  码" textalignment="left">
          <hbox.margin>
            <insets bottom="10.0" left="-290.0" top="140.0" />
          </hbox.margin>
        </label>
        <textfield fx:id="password" id="password" prefheight="30.0" prefwidth="200.0">
          <hbox.margin>
            <insets bottom="10.0" left="10.0" right="10.0" top="140.0" />
          </hbox.margin>
        </textfield>
        <button id="region" contentdisplay="center" font="$x1" minheight="28.0" mnemonicparsing="false" opacity="0.79" prefheight="35.0" prefwidth="75.0" text="注册" textalignment="center">
          <hbox.margin>
            <insets bottom="10.0" left="-240.0" top="200.0" />
          </hbox.margin>
        </button>
        <button id="login" font="$x1" minheight="28.0" mnemonicparsing="false" opacity="0.79" prefheight="35.0" prefwidth="75.0"
                text="登录" onaction="#btnclick" >
          <hbox.margin>
            <insets bottom="10.0" left="60.0" top="200.0" />
          </hbox.margin>
        </button>
      </children>
    </hbox>
  </children>
</anchorpane>

• 创建loginfxml类，指定fxml文件的路径，及引入fxml文件所需的样式

import de.felixroske.jfxsupport.abstractfxmlview;
import de.felixroske.jfxsupport.fxmlview;

@fxmlview(value = "/static/fxml/login.fxml", css = {"/static/style/login.css"},title = "用户登录")
public class loginfxml extends abstractfxmlview {

}

可以来了解下fxmlview的参数

@component
@retention(retentionpolicy.runtime)
public @interface fxmlview {
    string value() default "";

    string[] css() default {};

    string bundle() default "";

    string title() default "";

    string stagestyle() default "utility";
}

• 创建logincontroller，与用户界面进行交互

import com.dome.maincontroller;
import com.dome.domain.student;
import com.dome.service.istudentservice;
import com.dome.view.loginfxml;
import de.felixroske.jfxsupport.fxmlcontroller;
import javafx.event.actionevent;
import javafx.fxml.initializable;
import javafx.fxml.fxml;
import javafx.scene.control.button;
import javafx.scene.control.textfield;
import org.springframework.beans.factory.annotation.autowired;

import java.net.url;
import java.util.list;
import java.util.resourcebundle;

@fxmlcontroller
public class logincontroller implements initializable {

    @fxml
    private button button;
    @fxml
    private textfield username;

    @autowired
    private istudentservice studentservice;

    private resourcebundle resourcebundle;

    @override
    public void initialize(url location, resourcebundle resources) {
        resourcebundle = resources;
    }

    @fxml
    public void btnclick(actionevent actionevent) {
        list<student> students = studentservice.listall();
        username.settext("helloworld");
    }

    @fxml
    public void btnloginclick(actionevent actionevent) {
        maincontroller.showview(loginfxml.class);
    }

}

• 创建main方法，启动项目

import com.dome.view.exportclassentityfxml;
import com.dome.view.loginfxml;
import de.felixroske.jfxsupport.abstractjavafxapplicationsupport;
import javafx.stage.stage;
import org.springframework.boot.autoconfigure.springbootapplication;
import org.springframework.context.annotation.componentscan;

/**
 * maven构建javafx+springboot项目启动类
 */
@componentscan({"com.dome.view","com.dome.controller","com.dome.service"})
@springbootapplication
public class maincontroller extends abstractjavafxapplicationsupport {

    public static void main(string[] args) {
        launch(maincontroller.class, exportclassentityfxml.class, args);
    }

    @override
    public void start(stage stage) throws exception {
        super.start(stage);
        stage.settitle("用户登录");
        //窗口最大化显示
//        rectangle2d primaryscreenbounds = screen.getprimary().getvisualbounds();
//        stage.setx(primaryscreenbounds.getminx());
//        stage.sety(primaryscreenbounds.getminy());
//        stage.setwidth(primaryscreenbounds.getwidth());
//        stage.setheight(primaryscreenbounds.getheight());
//        stage.setmaximized(true);//设置窗口最大化
//        stage.setfullscreen(true);//全屏显示，esc退出
//        stage.setalwaysontop(true);//始终显示在其他窗口之上
    }
}

其中componentscan用来设置扫描包的中的类。

最后项目结构入下：
