From Hottest to Obsolete: A Critical Review of 13 Java Web Frameworks

Evaluation dimensions

Six objective criteria are used to compare Java web frameworks: performance (throughput, latency, resource usage), ecosystem maturity (community activity, documentation, third‑party library support), learning curve (initial difficulty, conceptual complexity), development efficiency (code volume, speed, maintenance cost), enterprise adoption (market share, large‑company usage), and innovation (technical novelty, architectural ideas).

Dominant tier – Spring Boot

Reason : Azul “State of Java 2025” reports a 42 % usage rate among microservice frameworks, the highest share.

Advantages : Convention‑over‑configuration, auto‑configuration, full Spring Cloud stack, extensive documentation, easy hiring.

Applicable scenarios : Enterprise applications, microservice architectures, any situation demanding stability.

Objective data : 79 k+ GitHub stars, 150 650 Stack Overflow tags.

High‑Performance tier

Quarkus

Reason : Cloud‑native framework with native GraalVM support, delivering the fastest cold‑start and smallest memory footprint.

Advantages : Native image generation, cold‑start 0.049 s (native) vs 1.909 s (Spring Boot JVM), max RSS 70.5 MB vs 388.9 MB (≈ 82 % reduction), developer experience close to Spring Boot.

Applicable scenarios : Kubernetes, serverless, microservices, performance‑critical workloads.

Micronaut

Reason : Compile‑time dependency injection eliminates reflection overhead.

Advantages : Startup 0.656 s (JVM) vs 1.909 s (Spring Boot JVM) – about 2.9× faster; max RSS 253.2 MB vs 388.9 MB (≈ 35 % reduction); GraalVM native image support; reactive‑friendly.

Applicable scenarios : Microservices, cloud‑native, performance‑sensitive applications.

Vert.x

Reason : Asynchronous, non‑blocking core makes it a champion for high‑concurrency workloads.

Advantages : Event‑driven, Reactor pattern, extreme throughput, multi‑language support.

Applicable scenarios : Real‑time systems, WebSocket services, IoT, any high‑throughput use case.

Objective data : Consistently appears in the TechEmpower Framework Benchmarks (e.g., vertx/, vertx-web/ entries).

Niche but solid tier

Helidon

Reason : Oracle‑backed MicroProfile implementation, lightweight microservice framework.

Advantages : Modular design, reactive support, GraalVM native image, well‑structured documentation.

Applicable scenarios : Microservices, cloud‑native, teams preferring standards.

Javalin

Reason : Minimalist framework that works equally well with Kotlin and Java.

Advantages : Gentle learning curve, concise code, decent performance, suited for small projects.

Applicable scenarios : RESTful APIs, prototypes, teaching projects.

Positioning : Similar to Node.js Express but with a smaller ecosystem.

Dropwizard

Reason : Veteran microservice framework integrating Jetty, Jersey, Jackson, etc.

Advantages : Out‑of‑the‑box, ops‑friendly (built‑in metrics), stable and reliable.

Applicable scenarios : RESTful services, projects needing rapid launch.

Current status : Once prominent, now squeezed by Spring Boot and newer entrants.

Legacy or declining tier

Play Framework

Reason : Scala/Java dual stack, reactive architecture, but low visibility in the Java ecosystem.

Advantages : Asynchronous, hot‑reload, REST‑friendly.

Disadvantages : Steep learning curve, community less active than Scala circles, few Java users.

Grails

Reason : Full‑stack framework based on Groovy, convention‑over‑configuration.

Advantages : Rapid development, great for quick prototypes.

Disadvantages : Groovy is niche, performance average, low enterprise adoption.

Apache Wicket

Reason : Component‑based, object‑oriented web framework.

Advantages : No need for JavaScript, fits traditional Java developers.

Disadvantages : Front‑end/back‑end separation is outdated, scarce learning resources.

Struts 2

Reason : Former heavyweight, now legacy.

Disadvantages : Frequent security vulnerabilities, outdated architecture, stagnant community.

Current status : Maintained only for legacy systems; new projects should avoid.

JSF (JavaServer Faces)

Reason : Part of the Java EE standard but poor developer experience.

Disadvantages : Bulky, low development efficiency, tight front‑back coupling.

Native Servlet + JSP

Reason : Raw technology stack, hand‑crafted.

Disadvantages : Requires writing everything manually, extremely low productivity, hard to maintain.

Conclusion – Tiered view

Based on the six dimensions, the frameworks are grouped into four tiers:

Dominant : Spring Boot

High‑Performance : Quarkus, Micronaut, Vert.x

Niche but solid : Helidon, Javalin, Dropwizard

Legacy / declining : Play Framework, Grails, Apache Wicket, Struts 2, JSF, native Servlet + JSP

This classification helps practitioners select the framework that best matches their specific scenario, balancing performance, ecosystem maturity, learning effort, development efficiency, enterprise adoption, and innovation.
