Question

spring-boot和cockroachDB出现问题。在我的本地计算机上运行cockraochDB和spring-boot。春季启动一开始，我就会例外。蟑螂在不安全的模式下运行。

application.yaml：

spring:
  datasource:
    url: jdbc:postgresql:localhost:26257/mydb?sslmode=disable
    username: myuser
    password: 
  jpa:
      properties:
         hibernate.dialect: org.hibernate.dialect.PostgreSQL94Dialect
      show-sql: true
      database-platform: org.hibernate.dialect.PostgreSQL94Dialect
      hibernate:
         ddl-auto: create

pom.xml部分：

我创建了两个用户。一种没有密码，另一种没有密码的是cockroachDB上的数据库“ mydb”。两者都不起作用。在spring.datasource.url中的网址上附加“？sslmode = disable”也无效。

没有密码的异常：

org.postgresql.util.PSQLException: The server requested password-based authentication, but no password was provided.

密码异常：

Caused by: org.postgresql.util.PSQLException: FATAL: password authentication failed for user "myuser"

感谢您的帮助

您必须在数据源URL中的postgressql之后使用://。

您的数据源网址应为

jdbc:postgresql://localhost:26257/mydb?sslmode=disable
