AntiPattern

Servlet/Maven Version Mismatch

spring-misconfig-version-and-servlet-mapping

Build and runtime misconfigurations break Spring Boot apps when dependency versions don’t match available artifacts or when servlet mappings and matcher servlet paths are ambiguous, causing missing classes, failed resolution, and requests landing on the wrong handler. All versions and mappings must align.

MATCHESSolution

Instead of `io.sentry:sentry-spring` one has to use `io.sentry:sentry-spring-boot-starter` — in the dependencies. Tension: remove the following from the code. Outcome: I've just tested in my actual project, and logged errors are still sent to Sentry correctly.

MATCHESSolution

I found a solution: — spring-boot-maven-plugin. Tension: all the options above are ignored by `maven-surefire-plugin`. Outcome: org.apache.maven.plugins maven-surefire-plugin 60.

MATCHESSolution

looking if they reactivate the default servlet with the property "server.servlet.register-default-servlet=true" — in spring boot. Tension: there are no web.xml files in the resulting jar.

MATCHESSolution

The only version supported right now is Jetty 12. — If you need support for the old `javax.servlet` namespace. Tension: Jetty 8 was EOL back in 2014. Outcome: use the `ee8` environment in Jetty 12.

MATCHESSolution

The issue was fixed in it — You can always override the dependency by specifying the version to be greater than 32.0.1. Outcome: Add the dependency in your pom.xml.

MATCHESSolution

For each MvcRequestMatcher, call MvcRequestMatcher#setServletPath to indicate the servlet path. Tension: This method cannot decide whether these patterns are Spring MVC patterns or not. Outcome: For each MvcRequestMatcher, call MvcRequestMatcher#setServletPath to indicate the servlet path.

MATCHESSolution

Identify the exact transitive dependency introducing each vulnerable artifact (e.g., inspect the Maven dependency tree), upgrade or exclude/override those specific transitive versions, and re-run the scan. Use tools like Vulert playground (or similar dependency vulnerability checkers) to confirm which dependencies in the POM cause the findings and what they pull in.

MATCHESSolution

Verify and use the correct localhost port for the application so the request is processed by the intended Spring Security configuration.

MATCHESSolution

Spring Boot 4 introduced some major changes where, by default, it uses Jackson 3 instead of Jackson 2. Outcome: making it a more suitable candidate over the no-arg counterpart.

MATCHESSolution

`spring-boot-starter-aop` has been renamed to `spring-boot-starter-aspectj` — Replace that in your pom.xml. Outcome: it will run fine.

MATCHESSolution

Use a stable 3.x version or a proper `4.0.x-SNAPSHOT` — `start.spring.io` shows Spring Boot 4.x SNAPSHOTs. Tension: using `4.0.0` (without `-SNAPSHOT`) in the parent POM breaks dependency management. Outcome: with the Spring snapshot repository configured.

MATCHESSolution

Spring Boot 4. Tension: Spring Boot 4 modularizes the codebase so various things are moved to different modules/dependencies.

MATCHESSolution

But you can try this workaround solution to see if this works: — spring-cloud-gcp-starter-secretmanager 7.3.2. Tension: enforce Spring Cloud GCP 7.x to use Spring Cloud Context 5.0.0. Outcome: which uses Spring Boot 4.0.0 starters.

MATCHESSolution

Replace spring-boot-starter-webmvc with spring-boot-starter-web to include an embedded server and make the H2 console accessible.

MATCHESSolution

If you see 2 versions of JPA — Spring Boot 3.3.x pulling in Spring Data JPA 3.3.x but another library in your project bringing an older Spring Data JPA. Tension: then remove the older version. Outcome: remove the older version.

MATCHESSolution

Change `source` & `target` from 8 to 24 — Tell IntelliJ to synchronize the POM. Do a Maven `clean`. Run your app. Tension: modules are not supported in -source 8.

MATCHESSolution

ctx.setParentLoaderPriority(false);. Tension: now my webapp classpath has priority over Jetty, and I can use logback. Outcome: and now my webapp classpath has priority over Jetty, and I can use logback.

MATCHESSolution

Add slf4j-bom 2.0.9 and log4j-slf4j2-impl 2.21.1 as a bridge for future SLF4J users

MATCHESSolution

Disabling the restart function didn't work for me — spring-boot-devtools which has a restart function. Tension: the restart class loader couldn't find the classes. Outcome: I simply removed devtools from Maven.

MATCHESSolution

you need to add the corresponding repository to your `pom.xml` — To resolve the issue. Tension: it kicks an error saying it can't find the artifact in the jboss-ga-repository. Outcome: After adding this, try running `mvn clean install` again, and it should work.

MATCHESSolution

Use a JAR-in-JAR packaging approach (e.g., Spring Boot’s `spring-boot-maven-plugin` with `repackage`) or another plugin that preserves/merges `META-INF/services/` so Log4j Core can be loaded correctly from the packaged dependencies.

MATCHESSolution

Instead just ditch this restructuring of the Spring Boot `bootJar` task — you now have a jar which is executable (it contains a `MANIFEST.MF` with all the proper entries). Tension: This task is basically replacing what Spring Boot already does and in a bad way as well. Outcome: let it do its thing instead of trying to be smarter.

MATCHESSolution

Version of java source and target that you want maven compiler plugin to support.

MATCHESSolution

If you meant to use the Spring Boot support — you can remove the `io.opentelemetry` dependencies, use the actuator starter. Tension: this behavior difference is called out in the Spring Boot docs. Outcome: refer to the Spring Boot docs.

MATCHESSolution

Also you should not need the plugin at the end. Tension: wrong dependency artifactId lombok-maven-plugin.

MATCHESSolution

Align all Spring Boot/Spring Security/Authorization Server dependency versions (e.g., upgrade the Spring Boot plugin to the same version and remove hardcoded version overrides), and prefer using org.springframework.boot:spring-boot-starter-oauth2-authorization-server so transitive dependencies match.

MATCHESSolution

After remove this row it run perfectly — previously I did specify spring framework as 6.1.14. Tension: conflict between dependency that include in 3.4.x. Outcome: it run perfectly.

MATCHESSolution

You will need to add `maven-processor-plugin` to `the pom.xml` — To ensure the generated classes are created before compilation. Tension: This plugin runs annotation processors like those required for Lombok and Hibernate JPA model generation during the generate-sources phase. Outcome: To ensure the generated classes are created before compilation.

MATCHESSolution

calls requesting the Provider afterwards do not work (the user returns null — after a Spring 5 -> 6 (Spring Boot 3.3.4) migration. Tension: I can sign in to my site, but calls requesting the Provider afterwards do not work. Outcome: I fixed this today, and found the following out that helped resolve this in my custom filter code.

MATCHESSolution

Only javax usage inside Jakarta EE is affected by modification restrictions. — Apache Commons IO uses javax.imageio. Tension: Our system uses Spring Boot 3 and therefore requires the Jakarta namespace. Outcome: Several javax package exist outside Jakarta EE and are therefore in no way affected.
