springboot mysql connection security

php editor Baicao will take you to delve into the issues regarding SpringBoot and MySQL connection security in Java. During the development process, it is crucial to ensure the security of database connections, especially when it comes to the storage and transmission of sensitive data. This article will share some best practices and common problem solutions on how to ensure connection security when SpringBoot integrates MySQL, to help developers better improve the security and stability of the system.

Question content

I used Springboot to build a Java web project and configured the MySQL database connection username and password in the application.yml file, but this is not secure enough. Is there any other secure way to configure user passwords for MySQL databases?

I hope to get a secure way to configure MySQL database user password, plain text cannot be used in the code

Solution

You can take advantage of the jasypt library, which provides a convenience Mechanism of encryption properties. The following is an example of how to configure jasypt using spring boot:

1. Add the jasypt dependency to the project's pom.xml (maven):

<dependency>
<groupid>com.github.ulisesbocchio</groupid>
<artifactid>jasypt-spring-boot-starter</artifactid>
<version>3.0.3</version>
</dependency>

2. Configure the encryption password in application.yml:

jasypt:
  encryptor:
   password: your_encryption_password # this should be kept secret elsewhere

3. Encrypt your mysql database password using jasypt cli tool or any other method supported by jasypt. For example, if your original password was a clear text password, it might look like this after encryption:

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/your_db
    username: your_user
    password: ENC(encryptedPassword) # Replace 'encryptedPassword' with the actual encrypted value

4. Now, when spring boot starts, jasypt will automatically decrypt the encrypted properties.
