Spring Framework 7.1 Release Notes
This is a preview page for Spring Framework 7.1.0, scheduled for November 2026.
This new generation raises its minimum requirements for the following:
- Jackson 3.1 for LTS support
- Hibernate ORM 7.3 support; runtime compatibility with Hibernate ORM 7.1 and 7.2 is retained for the time being.
We noticed that the JAXB message converter can consume a lot of CPU resources at runtime, even if XML isn't being used by the application. The "jakarta.xml.bind:jakarta.xml.bind-api" dependency is very common in Servlet applications and is often auto-detected by HttpMessageConverters as a valid choice.
As of Framework 7.1, HttpMessageConverters will not auto-detect JAXB converters for server applications. RestTemplate and RestClient will still detect it, because the CPU overhead there is less important.
You can bring back this converter in your server application with the following configuration:
@Configuration(proxyBeanMethods = false)
class JaxbConverterConfiguration implements WebMvcConfigurer {
@Override
public void configureMessageConverters(HttpMessageConverters.ServerBuilder builder) {
builder.withXmlConverter(new Jaxb2RootElementHttpMessageConverter());
}
}- The
AllEncompassingFormHttpMessageConverteris deprecated in favor of the newMultipartHttpMessageConverter. It is not configured by default anymore in HTTP clients and server applications.
Before Spring Framework 7.1, Multipart payloads could be read/written in Spring MVC applications with the Servlet Multipart Resolver support. RestTemplate and RestClient could send Multipart requests thanks to the FormHttpMessageConverter. This means HTTP clients could not read multipart responses and you couldn't thoroughly test your Multipart endpoints with RestTestClient.
As of 7.1, Spring Framework now dedicates FormHttpMessageConverter to URL encoded forms and ships a new MultipartHttpMessageConverter that can write and read Multipart payloads.
Check out in the reference documentation how RestClient can parse Multipart responses as MultiValueMap and how you can use RestTestClient to test your Multipart server endpoints.
