Moving from Spring Framework 6 to 7 is not just a version-number change: the Java 17 floor remains, but Spring 7 sets a Jakarta EE 11 baseline and removes or changes several contracts that applications and libraries may rely on. Start by identifying your exact 6.x version, then check your JDK, container and dependencies before auditing source code, deprecations, null-safety and tests. Spring Framework 7.0’s upgrade notes are specifically written for upgrades from 6.2; applications on earlier 6.x releases need to account for intervening changes as well.
What should you check before upgrading?
Use the Spring Framework project’s version guidance and the Spring Framework 7.0 Release Notes as your baseline, then verify every integration against the versions your application actually uses. Spring’s stated compatibility requirements do not guarantee that a particular application, third-party library or deployment platform will work without changes.
| Area | Spring 6.2 context | Spring 7.x baseline or guidance | Upgrade implication |
|---|---|---|---|
| Java | JDK 17–25 | JDK 17–25+; JDK 25 or higher is recommended for production. The project says it fully tests and supports LTS releases 17, 21 and 25. | Java 21 or 25 is not a mandatory minimum. Check the project’s current support policy as well as your runtime, compiler settings, build plugins and CI images. (Spring Framework version guidance) |
| Jakarta EE and Servlet | Jakarta EE 9–10; Servlet 6.0 is a common EE 10 baseline. | Jakarta EE 11 baseline, with early EE 12 support; Servlet 6.1. The 7.0 release notes cite Tomcat 11.0 and Jetty 12.1. | Confirm that application, container-provided and transitive APIs resolve to Jakarta versions, and test on the intended production container. (Version guidance; Spring Framework 7.0 Release Notes) |
| Persistence | JPA 3.1 is a common EE 10 baseline. | JPA 3.2; the release notes mention Hibernate ORM 7.1 and 7.2. | Check the provider, persistence-unit bootstrapping and any custom persistence integration. (Version guidance; Spring Framework 7.0 Release Notes) |
| Validation | Bean Validation 3.0 is a common EE 10 baseline. | Bean Validation 3.1; the release notes mention Hibernate Validator 9.0 and 9.1. | Verify the validation provider and parameter-name compilation settings. (Version guidance; Spring Framework 7.0 Release Notes) |
| Kotlin, tests and networking | Verify the versions used by your application. | The 7.0 release notes list Kotlin 2.2, JUnit 6 and Netty 4.2. | Check build plugins and test dependencies as well as runtime libraries; validate each integration’s compatibility separately. (Spring Framework 7.0 Release Notes) |
| Native images | Verify the setup used by your application. | The 7.0 release notes specify GraalVM 25 and its exact reachability metadata format. | If you build native images, check both the GraalVM version and metadata format used in your build. (Spring Framework 7.0 Release Notes) |
As of the Spring project’s version guidance available in October 2026, 7.0.x is the current production line and 7.1.x is scheduled for November 2026. The same guidance stated that open-source support for 6.2 ends in June 2026, while commercial long-term options remain available. Check the project’s current release and support guidance before making a maintenance decision; release schedules and support terms can change.

Check annotation imports and logging dependencies
Spring Framework 7 no longer supports javax.annotation and javax.inject annotations. If your code uses annotations such as @Resource, @PostConstruct or @Inject from those packages, migrate the imports and dependencies to jakarta.annotation and jakarta.inject where appropriate. This is a targeted annotation migration; it does not mean every package beginning with javax should be changed indiscriminately.
#1 Best Overall
Spring 7 also removes the spring-jcl module in favor of Apache Commons Logging 1.3.0. The change is transparent for most applications because spring-jcl was generally brought in transitively, and logging API calls ordinarily do not need rewriting. Inspect your dependency graph and any explicit module or exclusion configuration rather than assuming a source-code change is required.
Audit code that treats HttpHeaders as a MultiValueMap
In Spring Framework 7.0, HttpHeaders no longer implements the MultiValueMap contract. The Spring Framework 7.0 Release Notes state: “This class no longer extends the MultiValueMap contract.” The statement refers specifically to HttpHeaders. The release also removes several methods; fallback methods such as asMultiValueMap are deprecated immediately.
Search application code and internal libraries for assignments, parameters, casts, adapters or overloads that depend on an HttpHeaders value being a MultiValueMap. Update the affected boundary to use the supported HttpHeaders API or an explicit adapter appropriate to the code’s needs. Compile against Spring 7 to expose method-level changes that a search for the interface relationship alone may miss.
Review custom JPA bootstrapping and JMS destination resolution
- Custom persistence-unit setup:
MutablePersistenceUnitInfono longer directly implements the standardPersistenceUnitInfointerface. If your application customizes persistence bootstrapping, review the Spring release notes’SpringPersistenceUnitInfoadapter guidance and test the custom path. - JMS: the default destination resolver now caches
Session-resolvedQueueandTopicinstances. Only if your application requires a fresh resolution on every call, configureDynamicDestinationResolverand verify the behavior.
Which Spring 7 deprecations need a migration plan?
A deprecation is a signal to inventory use and review replacement guidance, not proof that the feature has already been removed. The Spring Framework 7.0 Release Notes mark the following APIs, integrations or configuration styles as deprecated:
Rank #3
- Spring MVC’s
<mvc:*>XML configuration namespace - JUnit 4 Spring TestContext support
- Jackson 2.x support
- Spring MVC
PathMatcheruse and theHandlerMappingIntrospectorSPI - Document and feed view packages and types
<lang:*>XML configuration and BeanShell scripting- Kotlin script templating support
- Spring nullness annotations using JSR 305 semantics, in favor of JSpecify
RestTemplatein the reference documentation
The release notes say there are no plans yet to remove the MVC XML namespace. They describe formal @Deprecated marking for RestTemplate as planned for 7.1, Jackson 2 auto-detection disablement as planned for 7.1, and complete Jackson 2 removal as planned for 7.2. These are plans stated in the 7.0 notes, not guarantees; check current release notes before setting a migration deadline. Prioritize based on whether your code uses the feature, whether its ecosystem remains compatible and any published removal plan.
How can null-safety and test behavior affect an upgrade?
Check Java and Kotlin nullability interpretation
Spring is moving from JSR 305 nullability semantics to JSpecify. That transition can change how Kotlin interprets nullability in Spring APIs and can affect some Java nullability checks or consumers of custom null annotations. Audit your own annotations and downstream use of Spring APIs, then run the compiler and static checks used by your project against the target versions. Treat warnings as a cue to verify the intended contract, not as proof that every warning indicates a runtime defect.
Test the SpringExtension context change
SpringExtension now uses a test-method-scoped extension context. Custom TestExecutionListener implementations may need to obtain the test class with testContext.getTestInstance().getClass() rather than testContext.getTestClass(). The release notes also document @SpringExtensionConfig(useTestClassScopedExtensionContext = true) as a compatibility option for affected nested test hierarchies. Exercise custom listeners and nested tests, and use that option only where the old class-scoped behavior is needed.

- Record your starting point. Note the exact Spring Framework 6 minor version, modules and dependency-management setup. Spring 7.0’s upgrade notes begin from 6.2, so teams on earlier 6.x versions should review intervening changes too.
- Confirm the Java and build baseline. Check local and production JDKs, compiler flags, build plugins and CI images against the project’s current version guidance.
- Validate the Jakarta EE and container layer. Confirm Servlet 6.1 availability and Jakarta API resolution in the target deployment environment; test on the actual intended container, not only with mocks.
- Check ecosystem dependencies. Review persistence and validation providers, Kotlin and JUnit dependencies, Netty integrations and native-image tooling where used. The version table above gives the release-note baselines; check each project integration’s compatibility independently.
- Search source and dependency configuration for removed contracts. Look for
javax.annotation,javax.inject, explicitspring-jcldependencies or exclusions, removedHttpHeadersmethods, and places that passHttpHeadersas aMultiValueMap. Search custom persistence bootstrapping forMutablePersistenceUnitInfouse. - Inventory relevant deprecations. Search for the deprecated APIs and configuration styles listed above, record where each is used, and consult current replacement guidance. Separate work that is needed to compile or run on 7.0 from work planned for later removal.
- Run nullability and test checks. Compile Java and Kotlin consumers with the target dependencies; test nested test hierarchies, custom listeners and test configurations that rely on Spring’s test extension.
- Run application-level integration tests on the target stack. Cover routing, serialization, persistence and deployment with the new libraries and container. Add focused coverage for servlet mocks, custom persistence bootstrapping or JMS resolution only where your application uses those paths.
Use the Spring Framework 7.0 Release Notes’ “Upgrading From Spring Framework 6.2” section and the project’s version guidance to validate the baseline. They provide a migration starting point, not an application-specific compatibility guarantee.
