Spring 2.7.0 WebFlux App Context Path is Not woking - spring-boot

Question

i am learning Spring web Flux And i want to access to my API but I got 404 even i specify
the path like this spring.webflux.base-path=/tsa/rest in my application.properties.
here is my config :
spring.webflux.base-path=/tsa/rest
server.port=8181
And this is my POM file. i generated my project via Spring initializer with the latest versions :
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.0</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.tsa</groupId>
<artifactId>tsa-api</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>tsa-api</name>
<description>Backend API</description>
<properties>
<java.version>17</java.version>
</properties>

<build>

<artifactId>spring-boot-maven-plugin</artifactId>

does anyone have any idea why the base-path is not working in my project? should I decrease my spring boot version? if yes what is the good version.
Thanks in advance.
