springBoot+javafx+mybatis搭建框架

利用springboot创建一个以javafx为前端页面展示，用mybatis作为沟通数据库的项目。
本例子只完成登录功能。
1.创建目录

Application：javafx程序主入口
Controller：前端页面控制层
mapper:mybatis 查询接口和xml
pojo:实体类
view:javafx视图
application.properties: 配置文件

2.导入pom文件

导入javafx

		UTF-8
		zh_CN
		1.8
		${java.version}
		2.1.1.RELEASE
		2.1.7
	

			org.springframework.boot
			spring-boot-starter-actuator
			${spring.boot.version}
		
		
			org.springframework.boot
			spring-boot-starter
			${spring.boot.version}
			
				
					org.springframework.boot
					spring-boot-starter-logging
				
			
		
		
			org.springframework.boot
			spring-boot-starter-log4j2
			${spring.boot.version}
		
		
		
			de.roskenet
			springboot-javafx-support
			${springboot-javafx-support.version}
		

导入数据库驱动

	
		
			mysql
			mysql-connector-java
			5.1.45
		
		
		
			org.mybatis.spring.boot
			mybatis-spring-boot-starter
			1.1.1
		

3.建表并添加一条语句

-- ----------------------------
-- Table structure for `login_user_info`
-- ----------------------------
DROP TABLE IF EXISTS `login_user_info`;
CREATE TABLE `login_user_info` (
  `userId` varchar(20) NOT NULL COMMENT '用户id',
  `loginName` varchar(20) NOT NULL COMMENT '用户名',
  `userName` varchar(20) NOT NULL COMMENT '真实姓名',
  `password` varchar(20) NOT NULL COMMENT '登录密码',
  `accountType` varchar(20) NOT NULL COMMENT '账号类型',
  `creatDate` datetime DEFAULT NULL COMMENT '创建时间',
  PRIMARY KEY (`userId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO login_user_info VALUES (‘1c98af14-7027-40a2-’, ‘11’, ‘张三’, ‘1’, ‘管理员’, ‘2019-03-23 13:36:00’);
4.配置文件

spring.datasource.url=jdbc:mysql://localhost:3306/hand?useUnicode=true&characterEncoding=utf8
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.username=
spring.datasource.password=

5.编写pojo

public class LoginUserInfo {
    private String userId;
    private String loginName;
    private String password;
    private String userName;
    private String accountType;
    private String creatDate;

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getLoginName() {
        return loginName;
    }

    public void setLoginName(String loginName) {
        this.loginName = loginName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getAccountType() {
        return accountType;
    }

    public void setAccountType(String accountType) {
        this.accountType = accountType;
    }

    public String getCreatDate() {
        return creatDate;
    }

    public void setCreatDate(String creatDate) {
        this.creatDate = creatDate;
    }
}

6.编写查询接口和对应xml

package mapper;
public interface queryMapper {
      public LoginUserInfo queryLoginInfo(@Param("loginName") String loginName , @Param("password")String password);
    public Integer queryLoginInfoByLoginName(@Param("loginName") String loginName);
}

    
        SELECT
          *
          from login_user_info
          WHERE
          1=1
          
             and loginName = #{name}
          
          
             and password = #{password}
          
    

    
        select
        Count(1) from login_user_info where loginName
        =#{loginName}
    
   

namespace:对应接口的全类名

7.编写fxml前端页面

fx:id：唯一标识 fx:controller：控制层

8.编写Controller

package controller;

import de.felixroske.jfxsupport.FXMLController;
import de.felixroske.jfxsupport.GUIState;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.geometry.Pos;
import javafx.scene.Parent;
import javafx.scene.control.Alert;
import javafx.scene.control.Label;
import javafx.scene.control.PasswordField;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.HBox;
import mapper.QueryMapper;
import org.springframework.beans.factory.annotation.Autowired;
import pojo.LoginUserInfo;

import java.net.URL;
import java.util.ResourceBundle;
@FXMLController
public class LoginController implements Initializable {
    @FXML
    private GridPane login;
    @FXML
    private TextField userName;
    @FXML
    private PasswordField passwordField;
    @Autowired
    private QueryMapper query;

    public void initialize(URL location, ResourceBundle resources) {

    }

    /**
     * 登录
     *
     */
    @FXML
    private void handleSubmitButtonAction(){
        String userNameStr = userName.getText().trim();
        String passwordStr = passwordField.getText().trim();
        Alert alert = new Alert(Alert.AlertType.INFORMATION);
        alert.setHeaderText(null);

        String str = "";
        if (userNameStr == null && passwordStr == null) {
            str = "用户名和密码不能为空！";
        } else if (userNameStr == null) {
            str = "用户名不能为空！";
        } else if (userNameStr == null) {
            str = "密码不能为空！";
        }
        if (str != null) {
            alert.setContentText(str);
            alert.showAndWait();
            return;
        }
        int num = query.queryLoginInfoByLoginName(userNameStr);
        if (num < 1) {
            alert.setContentText("用户名错误，请检查用户名！");
            alert.showAndWait();
            return;
        } else {
            LoginUserInfo info = checkLogin(userNameStr, passwordStr);
            // 登录
            if (info != null) {
                GUIState.getScene().setRoot(successpage());
                GUIState.getStage().setWidth(1000);
                GUIState.getStage().setHeight(700);
                GUIState.getStage().setX(150);
                GUIState.getStage().setY(50);
                GUIState.getStage().setResizable(true);

            } else {
                alert.setContentText("请输入正确的密码！");
                alert.showAndWait();
            }
        }

    }

    public Parent successpage(){
        HBox hbox = new HBox();
        Label label = new Label("登录成功");
        hbox.getChildren().add(label);
        hbox.setAlignment(Pos.CENTER);
        return hbox;
    }
    /**
     * 判断账号和密码是否正确
     */
    private LoginUserInfo checkLogin(String userName, String password) {
        return query.queryLoginInfo(userName, password);
    }
}

9.编写view

package view;

import de.felixroske.jfxsupport.AbstractFxmlView;
import de.felixroske.jfxsupport.FXMLView;

@FXMLView(fxml = "路径\LayoutPage_login.fxml")
public class LayoutView extends AbstractFxmlView {
}

10.编写程序主入口

package Application;

import de.felixroske.jfxsupport.AbstractJavaFxApplicationSupport;
import javafx.application.Application;
import javafx.stage.Stage;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import view.LayoutView;
@SpringBootApplication
@MapperScan("main.**")
public class Main extends AbstractJavaFxApplicationSupport{

    public static void main(String[] args) {

        launch(Main.class , LayoutView.class ,args);
    }


}
