SpringBoot整合JavaFx（⼗三）
SpringBoot整合JavaFx（⼗三）
在Java中，基本上万物可springboot… 整合了spring全家桶，你可以很⽅便整合它的⽣态框架。
JavaFx也能整合springboot，下⾯我就演⽰javafx+springboot操作数据库吧，学习了下⾯的⽅式，针对其他main⼯程也适⽤。整合过程主要分三步：
1、引⼊springboot依赖
2、配置
3、加载fxml时注⼊bean
特别注意第三点，使⽤javafx提供的控制器⼯⼚能轻松注⼊。开发模式类似MVC，只不过视图变成了fxml。
⼀、配置
⽤IDEA初始化⼀个springboot项⽬，，Maven依赖如下
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="/POM/4.0.0"xsi="/2001/XMLSchema-instance"

配置application.properties
spring.main.web-application-type=none
spring.main.allow-bean-definition-overriding=true
# 应⽤名称
spring.application.name=springboot-javafx-demo
# 数据库驱动：
spring.datasource.sql.cj.jdbc.Driver
# 数据源名称
spring.datasource.name=defaultDataSource
# 数据库连接地址
spring.datasource.url=jdbc:mysql://localhost:3306/test?serverTimezone=UTC # 数据库⽤户名&密码：
spring.datasource.username=root
spring.datasource.password=123456
⼆、编写启动类
import Application;
import FXMLLoader;
import Scene;
import VBox;
import Stage;
import Callback;
import SpringApplication;
import SpringBootApplication;
import ConfigurableApplicationContext;
import URL;
@SpringBootApplication
public class SpringbootJavafxDemoApplication extends Application {
// 任何地⽅都可以通过这个applicationContext获取springboot的上下⽂
public static ConfigurableApplicationContext applicationContext;
private static String[] args;
@Override
public void start(Stage primaryStage)throws Exception {
URL resource =getClass().getResource("/fxml/login.fxml");
if(resource ==null){
throw new Exception();
}
// 加载 fxml 下⾯的逻辑可以单独封装
FXMLLoader loader =new FXMLLoader(resource);
loader.setControllerFactory(new Callback<Class<?>, Object>(){
@Override
public Object call(Class<?> param){
// 控制器⼯⼚提供bean注⼊，此处的缺点是不能根据bean名字注⼊，只能通过class类型注⼊bean
/
/ 解决⽅案：
// 1、Bean("Bean Name", Bean.class);
// 2、@Autowired private ApplicationContext applicationContext;
// Object bean_name = Bean("bean Name", Bean.class);
Bean(param);
}
});
// 加载
VBox root = loader.load();
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
public static void main(String[] args){
SpringbootJavafxDemoApplication.args = args;
launch(args);
}
@Override
public void init()throws Exception {
// 启动springboot
applicationContext = SpringApplication.run(SpringbootJavafxDemoApplication.class, args);
}
@Override
public void stop()throws Exception {
// 关闭springboot
applicationContext.stop();
}
}
/fxml/login.fxml内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<?import l.*?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.VBox?>
<?import Font?>
<VBox maxHeight="-Infinity"maxWidth="-Infinity"minHeight="-Infinity"minWidth="-Infinity"prefHeight="330.0"
controller="ller.LoginController"
prefWidth="430.0"xmlns="javafx/javafx/11"fx="javafx/fxml/1">
<AnchorPane prefHeight="330.0"prefWidth="430.0">
<children>
<Label layoutX="99.0"layoutY="183.0"text="账号：">
<font>
<Font size="14.0"/>
</font>
</Label>
<Label layoutX="99.0"layoutY="217.0"text="密码：">
<font>
<Font size="14.0"/>
</font>
</Label>
<Button id="loginButton"layoutX="97.0"layoutY="270.0"mnemonicParsing="false"prefHeight="35.0"prefWidth="236.0"
text="登录"textAlignment="CENTER"textFill="WHITE">
<font>
<Font size="14.0"/>
</font>
</Button>
<CheckBox layoutX="98.0"layoutY="243.0"mnemonicParsing="false"text="⾃动登录"textFill="#a6a6a6"/>
<CheckBox layoutX="188.0"layoutY="243.0"mnemonicParsing="false"text="记住密码"textFill="#a6a6a6"/>
<Label layoutX="277.0"layoutY="242.0"text="回密码"textFill="#a6a6a6">
<font>
<Font size="14.0"/>
</font>
</Label>
<TextField layoutX="146.0"layoutY="183.0"prefHeight="23.0"prefWidth="182.0"/>
<PasswordField layoutX="146.0"layoutY="216.0"prefHeight="23.0"prefWidth="182.0"/>
</children>
</AnchorPane>
</VBox>
编写⼀个controller触发按钮事件
