This article delves into how to precisely control the execution order of Filters in Spring Boot applications, particularly ensuring that custom Filters (such as MDC Filter) run after the Spring Security Filter. By analyzing the default registration mechanism of Spring Security Filters, it reveals the limitations when using @Order annotation or FilterRegistrationBean to set order. The article details the solution of explicitly registering the Spring Security Filter and setting its order, with complete code examples. Additionally, it briefly covers improvements in Spring Boot 1.2 and later, as well as methods for relative order control using HttpSecurity, providing comprehensive technical guidance for developers.

This article provides an in-depth analysis of the common 'Error creating bean with name \'securityFilterChainRegistration\'' error encountered when integrating Spring Security into Spring Boot projects. Through a detailed case study, it explores the root causes, including improper dependency management, configuration conflicts, and proxy class access exceptions. Based on the best-practice answer, the article systematically proposes solutions such as using Spring Boot Starter dependencies, optimizing security configuration classes, removing redundant annotations, and adjusting bean definition order. With code examples and configuration adjustments, it explains how to avoid version incompatibilities and auto-configuration conflicts to ensure correct initialization of the security filter chain. Finally, it summarizes key points for maintaining Spring Security stability in microservices architecture, offering a comprehensive troubleshooting and repair guide for developers.
