问题
I am trying to connect my Spring Boot application to a PostGresSql database. But every time I get error in setting up SSL connection error.
My application.properties file is given below:-
server.port=8443
spring.datasource.url=jdbc:postgresql://localhost:5432/testdb
spring.datasource.username=postgres
spring.datasource.password=1234
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.dbcp2.test-while-idle=true
server.ssl.key-alias=selfsigned_localhost_sslserver
server.ssl.key-password=changeit
server.ssl.key-store=ssl-server.jks
server.ssl.key-store-provider=SUN
server.ssl.key-store-type=JKS
The ssl-server.jks file is in src/main/resources folder. I am ading the console mesage below:-

回答1:
try with below in your application.properties
spring.datasource.url=jdbc:postgresql://localhost:5432/testdb?sslMode=disable
OR
spring.datasource.url=jdbc:postgresql://localhost:5432/testdb?useSSL=false
Update your settings to below and should work, if not works then convert your jks to p12 file and use p12 format with keyStoreType=PKCS12
server.ssl.enabled=true
server.port=8443
server.ssl.key-store=classpath:ssl-server.jks
server.ssl.keyStoreType=JKS
server.ssl.key-store-password=*********
server.ssl.key-password=************
回答2:
You can disable ssl using following configuration:
server.ssl.enabled=false
Also, key store password setting is missing from your configuration:
server.ssl.key-store-password=changeit
回答3:
For me worked the same as @kj007 mentioned, but "sslmode" instead of "sslMode". Detailed about using SSL together with PostgreSQL.
spring.datasource.url=jdbc:postgresql://localhost:5432/testdb?sslmode=disable
回答4:
Probably you don't need SSL connection for you local environment. I mean without SSL config your connection to Postgres should work. Additionally you can check following link https://stackoverflow.com/a/19627306/10367907
回答5:
I have used the command line to forward the localport to the ssl server.
Ssh -L 5432:localhost:60901 gateway-username@gateway-ip
Then type the password of gateway.
Then in application.properties file
spring.datasource.platform=postgres
spring.datasource.url=jdbc:postgresql://localhost:5432/database_name
spring.datasource.username=username
spring.datasource.password=password
spring.jpa.show-sql=true
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
