我创建了自己的证书并配置了postgresql.conf文件：
...
#authentication_timeout = 1min # 1s-600s
ssl = true # (change requires restart)
ssl_ciphers = 'HIGH:MEDIUM:+3DES:!aNULL' # allowed SSL ciphers
# (change requires restart)
#ssl_prefer_server_ciphers = on # (change requires restart)
#ssl_ecdh_curve = 'prime256v1' # (change requires restart)
ssl_cert_file = '/etc/ssl/certs/company/database/certificate' # (change requires restart)
ssl_key_file = '/etc/ssl/certs/company/database/key' # (change requires restart)
ssl_ca_file = '/usr/share/ca-certificates/company/ca/certificate' # (change requires restart)
#ssl_crl_file = '' # (change requires restart)
#password_encryption = on
#db_user_namespace = off
#row_security = on
...
然后,我允许服务器连接到数据库pg_hba.conf：
...
hostssl postgres postgres XXX.XXX.XXX.XXX/0 md5
...
因此,我可以通过psql命令行连接到它：
psql (9.5.3)
SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES256-GCM-SHA384, bits: 256, compression: off)
Type "help" for help.
postgres=#
但是,当我尝试通过java应用程序打开与数据库的连接时,即使我向信任库提供了包含我的数据库证书的东西,也始终无法获得与它的连接：
mvn package -Djavax.net.ssl.trustStore=/opt/app/truststore -Djavax.net.ssl.trustStorePassword=changeit
例外：

通过psql,一切似乎都可以正常运行,而不是与我的应用程序一起运行.
有什么建议吗？
编辑：
我的props.properties文件：
uatDb.user=postgres
uatDb.password=password
uatDb.driverClass=org.postgresql.Driver
uatDb.jdbcUrl=jdbc:postgresql://<server_name>:1234/uat?ssl=true
uatDb.port=5443
uatDb.name=uat
uatDb.host=<server_name>
解决方法:
我相信也需要密钥库.由于ssl = true应该为您的自签名证书要求一个私钥.我还将添加“ nonValidating SSLFactory”设置
?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory
另外,您的server_name：1234的端口设置与5432不匹配.
“ parseUrl”是一个空错误,可能是JDBC URL中某个变量的设置不正确.
