Проблемы в решении заполнителей в bootstrap.properties после обновления до Springboot 2

Question

Пружинная зависимость:

     <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

Зависимость Spring-cloud:

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.M8</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

bootstrap.properties:

spring.cloud.config.failFast=true
spring.profiles.active=${ACTIVE_PROFILES:dev}
spring.cloud.config.uri=${CLOUD_CONFIG_URL:http://domainname/cloud-config}
spring.cloud.config.username=${CLOUD_CONFIG_USERNAME}
spring.cloud.config.password=${CLOUD_CONFIG_PASSWORD}

Answer 1

Понял это:

spring.cloud.config.username=${CLOUD_CONFIG_USERNAME}
spring.cloud.config.password=${CLOUD_CONFIG_PASSWORD}

должен быть изменен на -

spring.cloud.config.username=${CLOUD_CONFIG_USERNAME:}
spring.cloud.config.password=${CLOUD_CONFIG_PASSWORD:}

Обратите внимание на двоеточие в конце. Это раньше работало, хотя.
