Spring Boot MongoDB Atlas: "An SRV host name '${env.MONGO_CLUSTER}' was provided that does not contain at least three parts"

I’m trying to connect my Spring Boot application to MongoDB Atlas, but I’m encountering the following error:

Caused by: java.lang.IllegalArgumentException: An SRV host name ‘${env.MONGO_CLUSTER}’ was provided that does not contain at least three parts. It must contain a hostname, domain name and a top level domain.
My application.properties file:

spring.application.name=movies
spring.data.mongodb.database=${env.MONGO_DATABASE}
spring.data.mongodb.uri=mongodb+srv://${env.MONGO_USER}:${env.MONGO_PASSWORD}@${env.MONGO_CLUSTER}

My .env file:

MONGO_USER=myUsername
MONGO_PASSWORD=Otek15767%2AGIRL2
MONGO_DATABASE=moviesdb
MONGO_CLUSTER=cluster0.mongodb.net

I have encoded the special character (*) in my password as %2A. However, I’m still encountering the SRV hostname error.

My dependencies in pom.xml:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>

          <artifactId>spring-dotenv</artifactId>
        <version>4.0.0</version>
    </dependency>
</dependencies>

What I’ve Tried:
Verified the Connection String:

Copied the connection string from MongoDB Atlas.
Replaced placeholders with the environment variables.
Encoded Special Characters:

Encoded the * in the password as %2A.
Validated Environment Variables:

Confirmed that MONGO_CLUSTER is set to cluster0.mongodb.net.
Restarted the Application:

Ensured the application picks up the latest .env values.

How do I resolve this

    Managed to resolve it by removing the env in application properties and having:

    spring.application.name=movies
spring.data.mongodb.database=${MONGO_DATABASE}
spring.data.mongodb.uri=mongodb+srv://${MONGO_USER}:${MONGO_PASSWORD}@${MONGO_CLUSTER}

    Try bypassing the application properties by adding the following directly to .env

    spring_data_mongodb_database=moviesdb
spring_data_mongodburi=mongodb+srv://myUsername:Otek15767*[email protected]

    This uses the Spring Boot mechanism for picking up application.properties values from env vars
