[FIXED] jdbc4.MySQLSyntaxErrorException: Unknown database

Issue

I am trying to connect my project to MySQL but I keep getting an error I am not familiar with and everything seems to be correct , This is spring boot Multi Modular Project MY main class - Module admin-rest

@EntityScan(basePackages = {"com.valentine.domain"})
@SpringBootApplication(scanBasePackages = {"com.valentine.adminportal", "com.valentine.service", "com.valentine.utility"})
@EnableJpaRepositories("com.valentine.repository")
@EnableTransactionManagement
@EnableAspectJAutoProxy(proxyTargetClass = true)
public class AdminPortalApplication {

    public static void main(String[] args) {
        SpringApplication.run(AdminPortalApplication.class, args);
    }

application.properties

spring.jpa.hibernate.format_sql=true

spring.datasource.url=jdbc:mysql://localhost:3306/bookstoredb
spring.datasource.username=root
spring.datasource.password=user
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.platform=mysql

spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1


spring.jpa.properties.hbm2ddl=update

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

spring.jpa.properties.hibernate.hbm2ddl.auto=update

spring.jpa.hibernate.ddl-auto=create
}

And my domain models are in another module called domain as you can see from my Entity scan in Main class

Errors and Exception

Thu Jan 18 02:28:05 MSK 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

Solution

Based on this line:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown database 'bookstoredb'

Looks like your database name was incorrect. Did you already double checked it? How did you create your database? You might want also to check the configuration of mysql on your XAMPP or whatever local server you use.
