大家好，我第一次尝试使用SpringBoot时遇到了这个错误，异常消息对我来说没有任何意义，错误消息如下：
2022-10-03 22:27:15.801 ERROR 22836 --- [ main] com.zaxxer.hikari.pool.HikariPool : HikariPool-1 - Exception during pool initialization.
org.postgresql.util.PSQLException: ��������: ���ݿ� "db_name" ������

And my application.properties is like this:
server.port=5432
spring.datasource.url=jdbc:postgresql://localhost:5432/db_name
spring.datasource.username=postgres
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgresSQLDialect
spring.jpa.properties.hibernate.format_sql=true

您有相同的端口，因为PostgreSQL使用的是端口5432，server.port是为了安装Spring运行的端口，您可以将server.port更改为另一个端口，例如：80,8080，...您应该将此行添加到配置中以加载PostgreSQL驱动程序
最后一行应改为：
