回答1:

this error maybe have lots of reason but after setup jHipster-API-gateway and Jhipster-Microservice locally in your machine change the username and password of your MySql database. so you must first open your mysql cli with the root username and type in the terminal this command:

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';

this command will create a new user for your local machine. remember to change the "newuser" and "password" to whatever you want to use. after that you must give the full privilege to your user so type this command in terminal :

GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost';

remember to change the "newuser" to whatever you set in the previous command.

in the API gateway application open this file:

src/main/resource/config/application-dev.yml

and change this line:

    type: com.zaxxer.hikari.HikariDataSource
    url: jdbc:mysql://localhost:3306/JhipsterStarteruseUnicode=true&characterEncoding=utf8&useSSL=false&useLegacyDatetimeCode=false&serverTimezone=UTC&createDatabaseIfNotExist=true
username: root
password:

to this :

    type: com.zaxxer.hikari.HikariDataSource
    url: jdbc:mysql://localhost:3306/JhipsterStarter?useUnicode=true&characterEncoding=utf8&useSSL=false&useLegacyDatetimeCode=false&serverTimezone=UTC&createDatabaseIfNotExist=true
username: newuser
password: password
