如何使用 Electron 通过 JDBC 连接到 MySQL 数据库

Question

So I've been tinkering (fresh out of college) with creating a DB app via Electron as practice. I've successfully created a Java-only program that uses JDBC to connect to an MySQL database, but now I have to integrate that with an Electron GUI somehow and frankly I have no idea how to proceed.

Most things I've searched explain that connecting to a database via JavaScript is possible though completely not recommended due to the security issues, so I'd like to do this as securely as possible.

Would anyone know how to run Java within an Electron application to connect to a database, or is there some other method I'm overlooking that makes this seemingly Sisyphean task more simple?

Sorry for the possible ignorance here, still learning the ins and outs of different frameworks and such. Any help is appreciated.

Answer 1

You should use node.js to access mysql. I find some example as below to be helpful to you. Pls see here https://ourcodeworld.com/articles/read/259/how-to-connect-to-a-mysql-database-in-electron-framework

To avoid link page unavailable, I pasted code here:

var mysql = require('mysql');

// Add the credentials to access your database
var connection = mysql.createConnection({
    host     : 'localhost',
    user     : 'root',
    password : null, // or the original password : 'apaswword'
    database : 'ourcodeworld-database'
});

// connect to mysql
connection.connect(function(err) {
    // in case of error
    if(err){
        console.log(err.code);
        console.log(err.fatal);
    }
});

// Perform a query
$query = 'SELECT * FROM `myTableName` LIMIT 10';

connection.query($query, function(err, rows, fields) {
    if(err){
        console.log("An error ocurred performing the query.");
        console.log(err);
        return;
    }

    console.log("Query succesfully executed", rows);
});

// Close the connection
connection.end(function(){
    // The connection has been closed
});

If you want your application more secure, you can follow these solution.

** solution 1: package your electron into exe file. so db connection info can not be seen by others. You can find more suggestion in this site.

** solution 2: You can build an independent service to process mysql DB using node.js or Java(Spring). Then using restful in https to access service to obtain info from DB. It is secure too
