This endpoint provides a comprehensive view of the configuration properties currently active in a <a href=\"..\/Spring-Boot\/\">Spring Boot<\/a> application. It aggregates data from various sources, including <a href=\"..\/Java\/\">Java<\/a> System Properties, OS environment variables, and configuration files like <code>application.properties<\/code> or <code>application.yml<\/code>.<\/p><p>As detailed in the <a href=\"https:\/\/docs.spring.io\/spring-boot\/docs\/current\/reference\/html\/actuator.html#actuator.endpoints.env\">Spring Boot Reference Documentation<\/a>, the endpoint is instrumental for debugging configuration hierarchy issues. It lists each <a href=\"..\/PropertySource\/\">PropertySource<\/a> in order of precedence, allowing developers to see which source is providing a specific value. To maintain security, <a href=\"..\/Spring-Boot\/\">Spring Boot<\/a> automatically sanitizes sensitive keys such as passwords, secrets, or API tokens, replacing their values with asterisks.<\/p><p>In addition to viewing the entire environment, users can query specific properties by appending the property name to the URL path. This <a href=\"..\/REST-API\/\">REST API<\/a> functionality is frequently utilized in <a href=\"..\/DevOps\/\">DevOps<\/a> pipelines and automated monitoring tools to verify deployment settings across different environments. Integration with tools like <a href=\"..\/Spring-Cloud-Config\/\">Spring-Cloud-Config<\/a> further extends its utility by displaying properties fetched from centralized configuration servers alongside local overrides.<\/p><ul><li><a href=\"..\/actuator-health\/\">actuator\/health<\/a><\/li><li><a href=\"..\/actuator-configprops\/\">actuator\/configprops<\/a><\/li><li><a href=\"..\/actuator-metrics\/\">actuator\/metrics<\/a><\/li><li><a href=\"..\/Spring-Cloud-Config\/\">Spring-Cloud-Config<\/a><\/li><\/ul><\/section>",
