## File purpose

The default Spring Boot application properties file. Controls application parameters and start-up modes.

## File location

The file is located in the folder **cvarc-application\src\main\resources**.

## File values

The file uses the YAML language to define properties in a hierarchical structure. When loaded into the application, the properties follow the default dot
notation.

The indentation levels used in the following table mirror the file itself.

<table><thead><tr><th>Key</th><th>Value</th><th>Description</th></tr></thead><tbody><tr><td>spring:</td><td /><td /></tr><tr><td> profiles:</td><td /><td /></tr><tr><td> default:</td><td><code>"local,local-content"</code></td><td>Default Spring profiles.</td></tr><tr><td>server:</td><td /><td>Subsection for application server properties.</td></tr><tr><td> port:</td><td><code>9090</code></td><td>The port used for the application external services.</td></tr><tr><td> servlet:</td><td /><td>Servlet configuration.</td></tr><tr><td> context-path:</td><td><code>"/cvarc-application"</code></td><td>The context path of the application.</td></tr><tr><td>management:</td><td /><td>Subsection for Spring Actuator application management.</td></tr><tr><td> endpoints:</td><td /><td>Actuator endpoints.</td></tr><tr><td> web:</td><td /><td>Web endpoints.</td></tr><tr><td> exposure:</td><td /><td>Exposed endpoints.</td></tr><tr><td> include:</td><td><code>"\*"</code></td><td>The endpoint IDs to include.</td></tr><tr><td>springdoc:</td><td /><td /></tr><tr><td> swagger-ui</td><td /><td /></tr><tr><td> enabled</td><td><code>false</code></td><td>Enable/disable the Swagger UI.
