IDEA 链接Mysql数据库并执行查询操作的完整代码

1、先写个 Mysql 的链接设置页面

package com.wretchant.fredis.menu.mysql;

import com.intellij.notification.NotificationType;
import com.intellij.openapi.actionSystem.AnAction;
import com.intellij.openapi.actionSystem.AnActionEvent;
import com.wretchant.fredis.gui.dialog.TableDialog;
import com.wretchant.fredis.util.NotifyUtils;
import com.wretchant.fredis.util.PropertiesUtils;
import org.jetbrains.annotations.NotNull;

import javax.swing.*;
import java.util.Map;
import java.util.Properties;

public class MysqlConfig extends AnAction {

    @Override
    public void actionPerformed(@NotNull AnActionEvent event) {

        Properties properties = PropertiesUtils.readFromSystem();
        if (properties != null) {
            TableDialog.TableField build = TableDialog.TableField.build(properties.stringPropertyNames());
            TableDialog dialog = new TableDialog("Mysql 连接配置", build);
            for (int i = 0; i < dialog.getLabels().size(); i++) {
                JLabel label = dialog.getLabels().get(i);
                JTextField textField = dialog.getInputs().get(i);
                String property = properties.getProperty(label.getText());
                textField.setText(property);
            }
            dialog.show();
            if (dialog.isOK()) {
                Map valueMap = dialog.getValueMap();
                valueMap.forEach(properties::setProperty);
                PropertiesUtils.write2System(properties);
            }
        } else {
            NotifyUtils.notifyUser(event.getProject(), "读取配置文件失败，配置文件不存在", NotificationType.ERROR);
        }
    }
