解决办法：

1、在本地安装Postgres数据库；

2、修改Spring Cloud Config Server 服务端 Postgres数据库连接配置文件licensingservice-dev.yml，如下所示：


spring.jpa.database: "POSTGRESQL"
spring.datasource.platform:  "postgres"
spring.jpa.show-sql: "false"
spring.database.driverClassName: "org.postgresql.Driver"
# spring.datasource.url: "jdbc:postgresql://database:5432/eagle_eye_dev"
spring.datasource.url: "jdbc:postgresql://localhost:5432/eagle_eye_dev"
# spring.datasource.username: "postgres_dev"
spring.datasource.username: "postgres"
# spring.datasource.password: "{cipher}d495ce8603af958b2526967648aa9620b7e834c4eaff66014aa805450736e119"
spring.datasource.password: "{cipher}2c644c00b51dbdd03116edd77be62774fc94b3c646f1c553015102680e1d1868"
spring.datasource.testWhileIdle: "true"
spring.datasource.validationQuery: "SELECT 1"
spring.jpa.properties.hibernate.dialect: "org.hibernate.dialect.PostgreSQLDialect"
redis.server: "redis"
redis.port: "6379"
signing.key: "345345fsdfsf5345"

3、修改Spring Cloud Config Server 服务端属性配置文件application.yml，如下所示：


#
#   This is the core configuration for a configuration service.  I have two examples here:
#
#       -  A configuration service which completelty loads the configuration for the services
#          from the local file server of the config service.  This should only be used for
#          demonstration purposes or for a small application with a limited number of services.
#
#       -  A configuraton service that uses a git-based repository to read the files from

4、修改Spring Cloud Config Server 服务端属性配置文件bootstrap.yml，如下所示：


spring:
  application:
    name: configserver
encrypt:
  key: IMSYMMETRIC

5、修改Spring Cloud Config Client 客户端属性配置文件bootstrap.yml，如下所示：


spring:
  application:
    name: licensingservice
  profiles:
    active:
      dev
  cloud:
    config:
      uri: http://localhost:8888

6、访问http://localhost:8888/licensingservice/dev，返回结果如下所示：
