springboot mysql connection security

I used Springboot to build a Javaweb 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 password for MySQL database? I'm hoping to get a secure way to configure a MySQL database user password without using clear text in the code

Is there any solution to perform the same/similar database operations simultaneously via multiple threads?

Using Java, SpringBoot and Hibernate, is there a way to allow multiple threads to perform a given operation simultaneously without causing deadlocks or stale data exceptions. For example, suppose an automation tool logs in twice at the same time, which results in one of the following scenarios: Deadlock because two threads (requests) update user records at the same time, e.g. storing the date/time of the user's last login. Stale data exception because one thread updated the user before another thread's transaction completed. This could be solved by adding synchronization on the user ID, but such a thing would have to be done everywhere, resulting in potential performance penalties and making the codebase more bloated and difficult to maintain. Alternatively, we can adjust the isolation level (maybe

Java Spring Boot Security Privilege Management Tips: Control Who Can Do What

SpringBootSecurity is a very popular Java framework that helps developers easily implement application security. springBootSecurity provides a rich set of features, including user authentication, authorization, cross-site request forgery (CSRF) protection, and more. In SpringBootSecurity, permission management is a very important task. It controls what users can do within the application. SpringBootSecurity provides two main permission management mechanisms: role-based permission management (RBAC) and expression-based permission management. Role-based access management (RBAC) RBAC is an

Java Spring Boot Security performance optimization: make your system fly

1. Code optimization to avoid using too many security annotations: In Controller and Service, try to reduce the use of @PreAuthorize and @PostAuthorize and other annotations. These annotations will increase the execution time of the code. Optimize query statements: When using springDataJPA, optimizing query statements can reduce database query time, thereby improving system performance. Caching security information: Caching some commonly used security information can reduce the number of database accesses and improve the system's response speed. 2. Use indexes for database optimization: Creating indexes on tables that are frequently queried can significantly improve the query speed of the database. Clean logs and temporary tables regularly: Clean logs and temporary tables regularly
