JHipster and mongodb : Error creating bean with name 'mongobee'

Question

I am rather new to JHipster and I followed their instructions in order to create a new app. The app was created, imported into STS as a Maven project and I updated it.

However as soon as I try to start it via the Boot Dashboard I get this output :

I tried to create a similar project but without a Mongodb and it worked.

Answer 1

This was able to solve my problem:

"Answered my own question...removing the @Bean definition from public Mongobee mongobee(...) in DatabaseConfiguration.java seems to do the trick. Haven't done any thorough testing, but the apps starts and I can create new users."

Answer 2

After creating a new JHipster project with MongoDb I had the same error.

Before running mvnw (on Windows) I forgot to run the MongoDb itself.

So running mongod.exe in the new command prompt, and then running mvnw solved the issue for me.

Answer 3

This error means that there was an error connecting to your database, it confirms this in your stacktrace:

Timed out after 30000 ms while waiting for a server

Please double check your database configuration in the application-dev.properties or application-dev.yml file under src/main/resources/config/.

Depending on whether you use YAML or JSON as the property definition file, double check the database configuration:

YAML:

spring:
    data:
        mongodb:
            host: <your_host_address>
            port: <your_port>
            database: <database_name>

JSON:

spring.data.mongodb.host=<your_host_address>
spring.data.mongodb.port=<your_port>
spring.data.mongodb.database=<database_name>
