A Comprehensive Guide to Context Path Configuration in Spring Web and Spring WebFlux

Introduction

Team is working on spring boot version upgrade to 3.x and java to java 17. We noticed a few changes required for Context Path. The context path plays a crucial role in web applications, serving as the prefix to all URLs within the application. Configuring the context path correctly is essential, especially in scenarios where multiple applications are deployed on the same server. In this guide, we'll explore how to configure the context path in both Spring Web and Spring WebFlux applications.

Configuring Context Path in Spring Web

In a traditional Spring Web application, configuring the context path can be done through application properties or XML configuration.

server.servlet.context-path=/myapp

Configuring Base Path in Spring WebFlux

In Spring WebFlux, you can indeed configure the base path directly using the spring.webflux.base-path property in the application.properties file. This property specifies the base path under which all WebFlux endpoints will be mapped.

Example application.properties:

spring.webflux.base-path=/myapp

This simple configuration effectively sets the context path for the Spring WebFlux application.

Conclusion

Configuring the context path is essential for maintaining a well-organized and structured web application. Whether you're using Spring Web or Spring WebFlux, the process of configuring the context path is straightforward and can be done through properties or programmatic configuration. By following the guidelines outlined in this guide, you can ensure that your applications are correctly configured and easily accessible under the desired context path.
