Я попал в проводную ситуацию,
, где я не могу получить конфигурацию источника данных с сервера конфигурации
@SpringBootApplication
@EnableConfigServer
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
Ниже приведен мой yml, который находится в моей файловой системе и называется это как demo-services-development.yml
spring:
datasource:
url: jdbc:mysql://localhost:3306/genesys?useSSL=false
username: root
password: Durairaj90
driver-class-name: com.mysql.jdbc.Driver
jpa:
properties:
hibernate:
dialect: org.hibernate.dialect.MySQL5Dialect
после этого я попытался получить доступ к своему серверу конфигурации из chrome http://localhost: 8888 / demo-services / development
Он возвращает конфиги источника данных как json, как показано ниже
{"name":"demo-services","profiles":["development"],"label":null,"version":null,"state":null,"propertySources":[{"name":"file:///C:/Users/USHA RAJESH/config-repo/demo-services-development.yml","source":{"spring.datasource.url":"jdbc:mysql://localhost:3306/genesys?useSSL=false","spring.datasource.username":"root","spring.datasource.password":"Durairaj90","spring.datasource.driver-class-name":"com.mysql.jdbc.Driver","spring.jpa.properties.hibernate.dialect":"org.hibernate.dialect.MySQL5Dialect"}}]}
Теперь я настроил этот сервер конфигурации для своих микросервисов с помощью следующих вещей: xml

Ниже мое приложение application.properties
spring.application.name=demo-services
spring.profiles.active=development
spring.cloud.config.uri=http://localhost:8888
Ниже мое основное занятие
@SpringBootApplication
public class DemoServiceApplication {
public static void main(String[] args) {
SpringApplication.run(DemoServiceApplication.class, args);
}
}
При запуске приложения я получаю исключение ниже

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
Пожалуйста, помогите мне избавиться от этого.
