在 Spring boot 应用程序中使用 PostgreSql 时出错 - 无法从数据库获取连接：设置 SSL 连接时发生错误

Question

我在我的 Macos 上使用 homebrew 安装了 PostgreSql-12。它运行良好并且能够在 PgAdmin 中使用，但在 java Spring boot 应用程序中使用数据库时抛出以下错误

Caused by: org.flywaydb.core.internal.exception.FlywaySqlException: Unable to obtain connection from database: An error occurred while setting up the SSL connection.
SQL State  : 08P01
Error Code : 0
Message    : An error occurred while setting up the SSL connection.

我尝试过的 - 在 postgresql.conf 中禁用 ssl = off

下面是pg_hba.conf文件-

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     trust
host    replication     all             127.0.0.1/32            trust
host    replication     all             ::1/128                 trust

重现步骤 -

1. 使用brew安装postgresql -brew install postgresql@12
2. Spring 数据源中使用的数据源 url -
   jdbc:postgresql://localhost:5432/test_db?reWriteBatchedInserts=true
3. 应用程序运行因 SSL 错误而失败

堆栈跟踪 -

SQL State  : 08P01
Error Code : 0
Message    : An error occurred while setting up the SSL connection.

如有任何帮助，我们将不胜感激。

Answer 1

我面临的问题并不明显。当我调试 Spring Boot 应用程序时，我发现以下异常被包装到 FlywaySqlException-

org.postgresql.util.PSQLException: Protocol error. Session setup failed

我刚刚将端口从 5432 更改为 5434，并且成功了。

从中得到帮助 - org.postgresql.util.PSQLException：协议错误。会话设置失败
