Spring Cloud Config Server with Database backend

I am trying to create a Spring Cloud Config Server that gets its Configurations from a database and not from the default git-repo.

Every time I try to run my Config Server Application I get this Error:

Execution failed for task ':config-server:applications:config-server:bootRun'.
> Process 'command 'C:\Program Files\choco\openjdk-jdk-11\latest\bin\java.exe'' finished with non-zero exit value 1

From the Server itself comes this message (reformatted for better reading):

[ERROR agnostics.LoggingFailureAnalysisReporter : 
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.
[main||||||| - |]]

My application.yaml has this part in it:

spring:
  application:
    name: my-services-api
  datasource:
    url: jdbc:h2:mem:testdb
    driver-class-name: org.h2.Driver
    platform: h2
    hikari:
      connection-timeout: 5000
      maximum-pool-size: 10
  cloud:
    config:
      server:
        jdbc:
          sql: SELECT KEY, VALUE from MY_PROPERTIES where APPLICATION=? and PROFILE=? and LABEL=?
          order: 1
  h2:
    console:
      enabled: true

As you can see, there is no spring.cloud.config.server.bootstrap=true so I don't know what it wants me to do.
I also don't want to use a git profile, so the Action doesn't help me at all.

Does someone know, how I can fix this issue? Thanks

Update: I added spring.cloud.config.server.git.uri and changed the order of jdbc to 1 and of git to 2.
After that it kind of worked but I still have the issue, that it won't read the configurations from the database
I started from scratch, did the same thing and then it worked fine

I was trying to debug your issue and I have following settings and could successfully start the server as well as query the API.

The main class

@EnableConfigServer
@SpringBootApplication
public class ConfigserverApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigserverApplication.class, args);
    }

}

#bootstrap.yml
spring:
  application:
    name: my-services-api
  datasource:
    url: jdbc:h2:mem:testdb
    driver-class-name: org.h2.Driver
    platform: h2
    hikari:
      connection-timeout: 5000
      maximum-pool-size: 10
  profiles:
    active: jdbc
  cloud:
    config:
      server:
        jdbc:
          sql: "SELECT properties.key, properties.value from properties where application=? and profile=? and label=?"
          order: 1
  h2:
    console:
      enabled: true

Also I have put the schema.sql and data.sql into classpath ( resources folder of maven project) so that they autopopulate the data into embedded h2 database.

#schema.sql

DROP TABLE IF EXISTS PROPERTIES;
    
CREATE TABLE PROPERTIES (
  id INT AUTO_INCREMENT  PRIMARY KEY,
  APPLICATION VARCHAR(25) NOT NULL,
  PROFILE VARCHAR(25) NOT NULL,
  LABEL VARCHAR(25) DEFAULT NULL,
  KEY VARCHAR(25) NOT NULL,
  VALUE VARCHAR(200) NOT NULL   
);
    
#data.sql
    
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.1', 'prop1', 'val11');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.1', 'prop2', 'val12');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.1', 'prop3', 'val13');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.0', 'prop1', 'val21');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.0', 'prop2', 'val22');
INSERT INTO PROPERTIES( APPLICATION, PROFILE, LABEL, KEY, VALUE) 
values('myapp', 'MYCLIENT', '1.0', 'prop3', 'val23');

And I could successfully start and query the Config server
