The actuator\/configprops<\/strong> endpoint is a specialized diagnostic tool provided by Spring Boot Actuator<\/a>. Its primary purpose is to expose a comprehensive report of all beans annotated with @ConfigurationProperties<\/a> within the ApplicationContext<\/a>. This allows developers to inspect the hierarchical structure of configuration data as it is perceived by the Spring Framework<\/a> at runtime.<\/p> When a request is made to this endpoint, it returns a JSON object containing details about the configured prefixes, the actual property values, and the underlying bean names. This is particularly useful for debugging issues related to Externalized Configuration<\/a>, where values might be overridden by environment variables, system properties, or profile-specific files. To ensure security, Spring Boot<\/a> automatically sanitizes sensitive information such as passwords, keys, and tokens in the output, a feature that can be further refined using Spring Security<\/a> configurations.<\/p> The structure of the response typically groups properties by their prefix, providing a clear mapping of how application.properties<\/code> or application.yml<\/a> entries are bound to Java objects. For more information on implementation and customization, refer to the Official Spring Boot Actuator API Documentation<\/a> and the community guides on Baeldung<\/a>.<\/p>Related Resources<\/h3>
