I have seen below syntax in a few configs but I cannot find reference or documentation for this anywhere.
spring:
datasource:
username: FILE(/etc/usernames....)
How does this work? Why not use file: instead of FILE(. Also, any reference would be great.

I am on learning stage of Spring Cloud & using spring version 2.4.3 and spring-cloud-version
2020.0.1 and I created two property file
application.yml
spring:
application:
name: cloud-server
server:
port: 8888
bootstrap.yml
spring:
cloud:
config:
server:
git:
uri: https://github.com/************/insurance-config-server
default-label: main
but still I got following error
***************************
APPLICATION FAILED TO START
***************************
Description:
Invalid config server configuration.
Action:
If you are using the git profile, you need to set a Git URI in your configuration. If you are using a native profile and have spring.cloud.config.server.bootstrap=true, you need to use a composite configuration.
How to solve this kind of error?
Did you have a bootstrap.yml file?
I had the same problem. My project did not have a bootstrap.yml, but I specified a dev activity file in the IDEA startup configuration, which caused the same error as you did. The error could not be found bootstrap.yml on startup. After deleting dev in IDEA startup configuration, it can start normally.
If you are following the example in the book you referenced then I will suggest you move this
spring:
cloud:
config:
server:
git:
uri: https://github.com/************/insurance-config-server
default-label: main
to application.yml
That is what I did and it worked for me
I have a new MongoDB, that means there's no user, password and/or an authentication database.
Translating this to a .properties file, this should be:
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
...and for .yaml/.yml:
spring:
data:
mongodb:
host: localhost
port: 27017
Now let's suppose I want to use environment variables instead, if they're set, like this:
spring:
data:
mongodb:
host: ${MONGODB_HOST:localhost}
port: ${MONGODB_PORT:27017}
Everything until now works as expected.
What I want to achieve is the same for the spring.data.mongodb.user, spring.data.mongodb.password and spring.data.mongodb.authentication-database properties. I've tried doing the same technique for these properties, but in case they're not found in the environment, an exception is thrown, like this:
spring:
data:
mongodb:
host: ${MONGODB_HOST:localhost}
port: ${MONGODB_PORT:27017}
username: ${MONGODB_USERNAME}
password: ${MONGODB_PASSWORD}
authentication-database: ${MONGODB_AUTHENTICATION_DATABASE}
I have even tried setting empty/blank valuesm like ${MONGODB_USERNAME:}, ${MONGODB_USERNAME:''} and ${MONGODB_USERNAME:""}.
How do I get to achieve this? Is it even possible?
I've not tried this, but Spring boot should be able to pickup environment variables and use them as properties without having to put them in the yaml file. For example if you name a OS environment variable SPRING_DATA_MONGODB_USERNAME the value should show up in the spring property spring.data.mongodb.username. This would allow you to specify the username property only when you require it.
The other way to do this is to use externalised config. If you are booting your application from a fat jar, an application.yml outside the jar in the same directory can add in your additional properties:
spring:
data:
mongodb:
username: fred
password: password
without affecting the properties specified in the application.yml provided inside the jar.
There's a long ordered list of where spring-boot looks for properties documented here.
I need some help to consume another .yml file that complement the original one in the application. Then I have a file filled by me(dev) however some configuration(as database infos) should be inserted by our clients.
The one which is in the application(application.yml) have general configs, the other on path C:\Users\Public\ datasource.yml have:
spring:
datasource:
platform: postgres
driverClassName: org.postgresql.Driver
url: jdbc:postgresql://localhost:5432/mydb
username: foo
password: bar
Has anyone done this before?
configure the below annotation at your main configuration class
#PropertySource("classpath:datasource.yml")
I have:
spring.datasource.driverClassName = com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?serverTimezone=Europe/Madrid
spring.datasource.username=root
spring.datasource.password=secret
spring.jpa.hibernate.ddl-auto=update
and It works fine.
But when I try to do it this way:
spring:
datasource:
driverClassName: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/test?serverTimezone=Europe/Madrid
username: root
password: secret
jpa:
hibernate:
ddl-auto: update
It fails with:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
I assume it is a silly syntax error, but I can't notice where it is.
If you are going to use the YAML syntax, you need to specify it by changing the name of the file from application.properties to application.yml.
YML is very sensitive. Make sure you:
Use spaces instead of tabs
Use the proper extension: application.yml
See this: https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-external-config-yaml
I'm using spring-cloud-config in my Spring Boot project and I don't understand how to interpolate environment variables.
For example I have MYSQL_PASSWORD variable set in the config server (as environment variable) and I want to get it from other clients, without redefining the variable inside all of them. This is my config:
service.yml (in config-server)
spring:
datasource:
url: jdbc:mysql://mysql:3306/${MYSQL_DATABASE}?autoReconnect=true&useSSL=false
username: ${MYSQL_USER}
password: ${MYSQL_PASSWORD}
bootstrap.yml (into the client)
spring:
application:
name: event-service
cloud:
config:
uri: http://config-service:8888
fail-fast: true
If I start my services with this configuration, placeholder ${MYSQL_***} is not interpolated and I cannot connect to the database obviously.
What I have to do to make it work is to define environment variables like MYSQL_*** also in the client.
This is weird for me as I want config-server to be the central repository for everything. Do you have any advice?
I suggest you try to replace ${MYSQL_USER} and ${MYSQL_PASSWORD} with ${mysql.user} and ${mysql.password} - that way you'll be relying on Spring Boot's default property replacement.
Although I'm not sure that configuration server supports what you're trying to use, I've never tried a similar use case, please write back with a solution if the approach I suggested didn't work :)
