Before upgrading, confirm your exact 6.x starting point, check Jakarta EE and library compatibility, search for affected APIs, then test against the actual target runtime and container. Spring’s 7.0 upgrade notes are framed around moving from 6.2; projects on earlier 6.x releases must account for intermediate changes as well.
What must be ready for Spring Framework 7?
Java 21 or 25 is not a hard minimum: Java 17 remains supported. The Spring Framework version guidance lists JDK 17–25+ for 7.x, says the project fully tests and supports LTS releases 17, 21, and 25, and recommends JDK 25 or newer for production. Verify the current support policy for your deployment before choosing a runtime.

The larger platform change is Jakarta EE 11. That affects APIs supplied by your servlet container and persistence, validation, and other libraries—not just Spring dependencies. The following are the baselines and ecosystem versions identified in the Spring Framework 7.0 release notes; they are not a guarantee that every integration in an individual application is compatible.

| Area | Spring 6.2 context | Spring 7 target | What to verify |
|---|---|---|---|
| Java | JDK 17–25 | JDK 17–25+; JDK 25+ recommended for production by Spring’s version guidance | Runtime, compiler level, build plugins, CI images, and current support policy. |
| Jakarta EE and Servlet | EE 9–10; Servlet 6.0 is a common EE 10 baseline | EE 11 baseline; Servlet 6.1 | Container and transitive APIs resolve to Jakarta versions. Spring’s 7.0 notes cite Tomcat 11.0 and Jetty 12.1 for Servlet 6.1. |
| Persistence | JPA 3.1 is a common EE 10 baseline | JPA 3.2; Hibernate ORM 7.1/7.2 are noted | Provider version, persistence-unit bootstrapping, and custom persistence code. |
| Validation | Bean Validation 3.0 is a common EE 10 baseline | Bean Validation 3.1; Hibernate Validator 9.0/9.1 are noted | Provider compatibility and parameter-name compiler settings. |
| Kotlin, tests, networking, native image | Verify the versions used by your 6.x project | Kotlin 2.2, JUnit 6, Netty 4.2, and GraalVM 25 with the exact reachability metadata format are listed | Build plugins and test dependencies as well as runtime libraries; verify each integration separately. |
These figures come from Spring Framework’s 7.0 release notes and version guidance. A passing dependency-resolution step alone does not establish that a provider, container, or application integration works at runtime.

Which changes can break source code or runtime behavior?
Annotation packages and logging dependencies
Spring Framework 7 no longer supports the javax.annotation and javax.inject annotations named in the release notes, including @Resource, @PostConstruct, and @Inject. Where these are used, migrate the imports and dependencies to their Jakarta counterparts, such as jakarta.annotation and jakarta.inject. This is not a reason to mechanically replace every javax.* reference: identify the specific APIs and dependencies your application uses.
The spring-jcl module is removed in favor of Apache Commons Logging 1.3.0. Spring’s notes say this should be transparent for most applications because the module was generally pulled in transitively and logging calls do not need to change. Check dependency management, exclusions, and packaging for code or libraries that explicitly expect the module rather than rewriting logging calls by default.
HttpHeaders no longer has the old MultiValueMap relationship
In Spring Framework 7.0, HttpHeaders no longer implements MultiValueMap. The release notes put it directly: “This class no longer extends the MultiValueMap contract.” Several methods were removed, and fallback methods such as asMultiValueMap are deprecated. Search for assignments, method parameters, casts, overload selection, and adapters that treat an HttpHeaders instance as a MultiValueMap; update the affected code to use the supported HttpHeaders API or an explicit adapter appropriate to the use case.

Spring test extension context scope
SpringExtension now uses a test-method-scoped extension context. Custom TestExecutionListener implementations that relied on testContext.getTestClass() may need to obtain the class through testContext.getTestInstance().getClass(). The release notes also document @SpringExtensionConfig(useTestClassScopedExtensionContext = true) as a compatibility option for affected nested test hierarchies. Exercise custom listeners and nested tests rather than assuming they behave as before.
Conditional persistence and JMS changes
- Custom JPA bootstrapping:
MutablePersistenceUnitInfono longer directly implements the standardPersistenceUnitInfointerface. If your code customizes persistence-unit bootstrapping, follow the release-note direction toSpringPersistenceUnitInfoand its adapter method. - JMS destinations: the default resolver now caches Session-resolved Queue and Topic instances. If your application requires fresh resolution on every call, configure
DynamicDestinationResolveras directed in the release notes.
Which Spring 7 APIs are deprecated, and how urgent are they?
Deprecation is a signal to inventory usage and plan a migration; it does not mean every item is removed in 7.0. Spring Framework 7.0 release notes identify the following deprecations. Check the current release notes and replacement guidance for your exact version before scheduling work, because stated future plans can change.
| Area | 7.0 status and planning note |
|---|---|
| RestTemplate | Deprecated in reference documentation in 7.0; formal @Deprecated marking was planned for 7.1 in the notes. |
| Spring MVC XML namespace | <mvc:*> configuration is deprecated. The notes say there are no plans yet to remove it. |
| Spring MVC routing and SPI | MVC PathMatcher use and the HandlerMappingIntrospector SPI are deprecated. |
| Testing | JUnit 4 Spring TestContext support is deprecated; the notes list JUnit 6 as an ecosystem minimum. |
| Serialization and views | Jackson 2.x support and document/feed view packages and types are deprecated. The notes planned to disable Jackson 2 auto-detection in 7.1 and complete removal in 7.2. |
| Other integrations | Kotlin script templating support, <lang:*> XML configuration, and BeanShell scripting are deprecated. |
| Nullness annotations | Spring’s nullness annotations using JSR 305 semantics are deprecated in favor of JSpecify. |
Treat planned release milestones as plans recorded in the 7.0 notes, not guarantees. For each deprecated feature you actually use, establish whether it is required, identify a supported replacement or an acceptable interim position, and confirm the removal schedule against current documentation.

- Pin down the starting point. Record the exact Spring Framework 6 minor and patch versions, modules, dependency-management source, and any Spring integrations. The 7.0 upgrade notes specifically address upgrading from 6.2. If you are on an earlier 6.x version, review changes introduced between your starting version and 6.2 as well as the 7.0 changes.
- Choose and validate the runtime baseline. Check Java runtime and compiler settings, compiler flags, build plugins, and CI images together. Decide whether the project’s production runtime meets the current Spring support policy; Java 17 remains the floor, while the version guidance recommends JDK 25 or newer for production on 7.x.
- Prove the Jakarta EE and container path. Confirm the target container supports Servlet 6.1 and that APIs supplied transitively or by the container use Jakarta namespaces and compatible versions. Run deployment tests on the intended production container, not only servlet mocks.
- Audit the dependency graph. Compare actual resolved versions with the 7.0 release-note minimums for Servlet, JPA, Bean Validation, Kotlin, JUnit, Netty, and—if building native images—GraalVM and reachability metadata. Check the relevant provider and integration documentation; a listed minimum does not certify every third-party combination.
- Search application and test code for removed contracts. Search source, tests, build files, and custom integration modules for
javax.annotation,javax.inject,spring-jcl, andHttpHeadersusages that depend onMultiValueMap. Review each match in context, then update imports, dependencies, or code contracts as needed. - Inventory deprecations by actual usage. Search for the deprecated features listed above and record where they are configured or called. Prioritize features with replacement work or stated removal plans, while distinguishing deprecated support from APIs removed in 7.0.
- Run a null-safety pass. Review Java and Kotlin consumers of Spring APIs, custom null annotations, compiler checks, and Kotlin nullability interpretation. Spring’s move from JSR 305 semantics to JSpecify can change how consumers interpret nullability; fix resulting warnings or errors deliberately rather than suppressing them wholesale.
- Target focused regression tests. If used by the application, test SpringExtension behavior, nested test hierarchies, custom test listeners, servlet mocks, custom persistence-unit bootstrapping, and JMS destination resolution. Include tests for custom code that adapts or wraps affected Spring APIs.
- Exercise end-to-end behavior on the target stack. Test routing, serialization, persistence, validation, and deployment with the intended container and upgraded libraries. Use integration tests where mocks cannot establish container or provider behavior, then verify the packaged application in the same kind of environment used for production.
- Make the upgrade-versus-delay decision against support dates. Spring’s version guidance identifies 7.0.x as the current production line and recommends upgrading to its latest 7.0.x release when possible; it states that open-source support for 6.2 ends in June 2026, with commercial long-term options available. Since those are time-sensitive statements and June 2026 has passed, check the current support policy and your applicable support arrangement before deciding to delay.
Keep a record of the starting versions, resolved dependency tree, code searches, test results, and any accepted deprecations. That turns the upgrade into a reviewable compatibility decision rather than a single framework-version change.
