PostgreSQL 驱动程序不接受 URL
PostgreSQL driver not accepting URL
我正在使用 Spring Boot 构建一个 rest api，我想连接到 Heroku 应用程序上的 Postgresql 数据库，但是在尝试 运行 该程序。

是不是定义数据源的语法错误url？
这是我的 application.properties:
spring.datasource.url=http://localhost:5432
spring.datasource.platform=POSTGRESQL
spring.datasource.driver-class-name=org.postgresql.Driver
还有其他人对此有疑问吗？
尝试像这样定义您的 spring.datasource.url：（将数据库名称替换为您的数据库名称。）
spring.datasource.url=jdbc:postgresql://localhost:5432/<database name>
这是您必须定义的PostgreSQL application.properties，请将dbname替换为您的数据库名称，将username替换为您的数据库用户名，将password替换为您的密码。
spring.datasource.url=jdbc:postgresql://localhost:5432/dbname
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.platform=postgres
spring.datasource.driver-class-name=org.postgresql.Driver
