Spring Cloud 2021.0.1 Release: New Features, Module Versions, and Compatibility

Hello everyone, I'm Chen (the author).

While browsing the Spring Cloud official documentation, I discovered that the Spring Cloud 2021.0.1 documentation has already been released, which made me feel the pressure of keeping up with the rapid updates.

Since the Maven repository has been updated, the dependency management snippet is as follows:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>2021.0.1</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

Module-Specific Updates

1. Spring Cloud Gateway

Added a new route predicate to check the allowed values of the X-Forwarded-For header.

Allows configuring the order of HandlerMapping in the Gateway; by default, HandlerMapping has priority, but it can be changed as needed.

2. Spring Cloud OpenFeign

Supports configuring the read timeout parameter readTimeout for OkHttpClient connections.

Improved FeignAutoconfiguration so that OAuth2FeignRequestInterceptor can include an AccessTokenProvider with load‑balancing interceptor.

3. Spring Cloud Sleuth

Fixed several obscure bugs (details can be found in the GitHub milestone).
