How can I prevent SQL injection in my Spring Boot application?

To prevent SQL injection in Spring Boot, use prepared statements and parameterized queries.

Can you give me an example of using prepared statements?

Sure! Instead of concatenating SQL strings, use the JdbcTemplate with placeholders like this: jdbcTemplate.query("SELECT * FROM users WHERE id = ?", new Object[]{userId});.

What about using JPA or Hibernate?

JPA and Hibernate automatically use parameterized queries, so as long as you use their methods, you're safe from SQL injection.

Are there any other security measures I should consider?

Yes, consider using input validation, escaping user inputs, and implementing proper authentication and authorization.
