🦉 Deserialization of Untrusted Data

[snykcareem]

The upgrade from Spring Boot 2.6.6 to 3.0.0 is a major version change with significant breaking changes that require mandatory code and environment modifications.

Key Breaking Changes:

• Java 17 Baseline: Spring Boot 3.0 requires Java 17 as the minimum version. Applications must be running on JDK 17 or later.
• Jakarta EE 9/10 Migration: This is the most impactful change. Spring Boot 3.0 has migrated from Java EE to Jakarta EE. This requires changing all javax.* package imports to their new jakarta.* equivalents across the entire codebase. For example, javax.servlet.http.HttpServletRequest becomes jakarta.servlet.http.HttpServletRequest.
• Dependency Upgrades: This release is built on Spring Framework 6.0 and includes major version bumps for most core dependencies, including Spring Security 6.0, Spring Data 2022.0, and Hibernate 6.1. These transitive upgrades introduce their own breaking changes.
• Spring Security 6.0: WebSecurityConfigurerAdapter has been removed. Security configuration must be rewritten using a component-based approach, typically by defining a SecurityFilterChain bean.
• Configuration Properties: Numerous configuration properties have been renamed or removed. For example, server.max.http.header.size is now server.max-http-request-header-size.

Recommendation:
This is a high-effort migration. It is strongly recommended to first upgrade to the latest Spring Boot 2.7.x release to resolve deprecations before moving to 3.0. Utilize tools like the spring-boot-properties-migrator module and OpenRewrite recipes to automate parts of the migration, particularly for package renames and property changes.
