I have generated an spring boot + angular application . imported entities with jdl. working properly with h2 . I am newbie and want to use mysql.I have configured datasource in application-dev.yml with following code.
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/blogdb?useUnicode=true&characterEncoding=utf8&useSSL=false
username: name
password:pass
h2:
console:
enabled: false
hikari:
data-source-properties:
cachePrepStmts: true
prepStmtCacheSize: 250
prepStmtCacheSqlLimit: 2048
useServerPrepStmts: true
jpa:
database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
database: mysql

Answer 1

This is not an answer but I needed more space than in comments.
I have generated an app using your .yo-rc.json file and jhipster 4.10.2, it works fine. I also have the Class-Path manifest warning but it's harmless and the application works.

So, I guess you're not pasting the real error.
What exactly is the symptom?

Answer 2

Try to create a new jhipster application, and choose Mysql at the creation moment. It takes few minutes, and you can check and compare.

Answer 3

Normally in application-dev.yml spacing is considered so in password to be
yours,
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/blogdb?useUnicode=true&characterEncoding=utf8&useSSL=false
username: name
password:pass
what to be done is,
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/blogdb?useUnicode=true&characterEncoding=utf8&useSSL=false
username: name
password: pass
just check it out

I had the same error if you are using docker, so replace localhost to your docker IP
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://192.168.99.100:3306/library
username: root
