Spring Boot 4 comes out in November 2025! With this in mind, lLet’s at least look at some of my favorite features together. Jakarta EE 11<\/strong> is the new baseline. We’ve retained a Java 17<\/strong> baseline but strongly<\/em> encourage a Java 25 posture whenever possible. We’ve moved the baseline to GraalVM 25<\/strong> for native images and updated our Kotlin<\/strong> support to Kotlin 2.2. The new generation of projects assumes the new Jackson 3<\/strong>. We’ve introduced JSpecify nullability<\/strong> annotations across the portfolio to finally eliminate Tony Hoare’s $1 billion dollar mistake \u2013 null references. Spring Boot 4 has decomposed the autoconfiguration artifact into smaller, more modular autoconfigurations<\/strong>.<\/p>\n\n\n\nOne of my favorite new features is API versioning<\/strong>. Here’s a Spring MVC controller with two endpoints, each designated a particular version, the default version of which we can specify with spring.mvc.apiversion.default=1.1<\/code>.<\/p>\n\n\n\n@RestController\n\nclass DogsController {\n\n\u00a0\u00a0\u00a0\u00a0...\n\n\u00a0\u00a0\u00a0\u00a0@GetMapping(value = \"\/dogs\",version=\"1.0\")\n\n\u00a0\u00a0\u00a0\u00a0Collection<Map<String, Object>> dogsClassic() {\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0...\u00a0\n\n\u00a0\u00a0\u00a0\u00a0}\n\n\u00a0\u00a0\u00a0\u00a0@GetMapping(value = \"\/dogs\", version = \"1.1\")\n\n\u00a0\u00a0\u00a0\u00a0Collection<Dog> dogs() {\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0...\u00a0\n\n\u00a0\u00a0\u00a0\u00a0}\n\n}<\/pre>\n\n\n\nI also love the new easy-mode declarative HTTP clients. Let’s build a client to talk to the Cat Facts API and then activate it using @ImportHttpServices(CatFacts.class)<\/code>:<\/p>\n\n\n\nrecord CatFact(@JsonProperty(\"fact_number\") int factNumber, String fact) { }\n\nrecord CatFactsResponse(Collection<CatFact> facts) { }\n\ninterface CatFacts {\n\n\u00a0\u00a0\u00a0\u00a0@GetExchange(\"https:\/\/www.catfacts.net\/api\")\n\n\u00a0\u00a0\u00a0\u00a0CatFactsResponse facts();\n\n}<\/pre>\n\n\n\nWe built a simple client, and it should work, but what if the service is down? In this case, we can enable resilient methods<\/strong> with Spring’s new @EnableResilientMethods<\/code> annotation. This gives us two new features: @ConcurrencyLimit <\/code>and @Retryable<\/code> (and the related RetryTemplate).<\/p>\n\n\n\n...\n\n\u00a0\u00a0\u00a0\u00a0@ConcurrencyLimit(10)\n\n\u00a0\u00a0\u00a0\u00a0@Retryable(maxAttempts = 4, includes = BadException.class)\n\n\u00a0\u00a0\u00a0\u00a0@GetMapping(\"\/facts\")\n\n\u00a0\u00a0\u00a0\u00a0Collection<CatFact> facts()\u00a0 throws Exception {\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0...\n\n\u00a0\u00a0\u00a0\u00a0}\n\n\u00a0\u00a0\u00a0\u00a0...<\/pre>\n\n\n\n <\/p>\n\n\n\n
Spring Framework 7 brings BeanRegistrar<\/code> configuration, which is a more dynamic alternative to Java configuration that can be used in conjunction with Java configuration and component scanning with the usual @Import<\/code> annotation.<\/p>\n\n\n\nclass MyBeanRegistrar implements BeanRegistrar {\n\n\u00a0\u00a0\u00a0\u00a0@Override\n\n\u00a0\u00a0\u00a0\u00a0public void register(BeanRegistry registry, Environment env) {\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0registry.registerBean(Runner.class);\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0registry.registerBean(Runner.class, spec -> spec\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0.description(\"description\")\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0.supplier(supplierContext -> new Runner(\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0supplierContext.bean(DogRepository.class), supplierContext.beanProvider(CatFacts.class)\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0.getIfUnique())\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0));\n\n\u00a0\u00a0\u00a0\u00a0}\n\n}<\/pre>\n\n\n\nSpring Security brings with it a lot of nice new features. Two of my favorites are multi-factor auth, allowing you to require that multiple authentication factors be present, and Customizer<HttpSecurity><\/code> beans for additive changes to the HttpSecurity<\/code> configuration.<\/p>\n\n\n\n@EnableGlobalMultiFactorAuthentication(\n\n\u00a0\u00a0\u00a0\u00a0authorities = { FactorGrantedAuthority.PASSWORD_AUTHORITY, FactorGrantedAuthority.OTT_AUTHORITY })\n\n@Configuration\n\nclass SecurityConfiguration {\n\n\u00a0\u00a0\u00a0\u00a0@Bean\n\n\u00a0\u00a0\u00a0\u00a0Customizer<HttpSecurity> httpSecurityCustomizer() {\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0return httpSecurity -> httpSecurity\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0.webAuthn(w -> ... )\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0.oneTimeTokenLogin(ott -> ... );\n\n\u00a0\u00a0\u00a0\u00a0}\n\n}<\/pre>\n\n\n\nThe code is here for your reference<\/a>.
