Caused by: java.lang.RuntimeException: Driver com.mysql.cj.jdbc.Driver claims to not accept jdbcUrl

Question

无法弄清楚导致问题的原因。

我的 application.properties 文件

    spring.datasource.url = "jdbc:mysql://localhost:3306/Medical_Tracking?useSSL=false"
    spring.datasource.username=root
    spring.datasource.password=root
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
    spring.jpa.show-sql=true
    spring.jpa.hibernate.ddl-auto=update
    spring.jpa.generate-ddl=true

快速帮助表示赞赏

Answer 1

your config spring.datasource.url should not use "", use spring.datasource.url = jdbc:mysql://localhost:3306/Medical_Tracking?useSSL=false instead

Answer 2

尝试在 applications.properties 文件中进行以下更改：

代替

 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

和

spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
