maven-spring-boot试图连接到mysql

我正在尝试将我的web应用程序连接到mysql。spring boot没有检测到数据库，但是可以连接到服务器。有没有人能把我引向正确的方向，这样它就能检测出模式。使用@entity注解，它应该在数据库中自动创建一个表作为“user”。它还应该说，在控制台“数据库可用”，我曾试图寻找网上，但没有结果。任何帮助都将不胜感激！

这是我的application.properties

  1. spring.datasource.url=jdbc:mysql://localhost:3306/espersdb
  2. spring.datasource.username=root
  3. spring.datasource.password=password
  4. spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
  5. spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
  6. spring.jpa.hibernate.ddl-auto=none

这是我的控制台

我已经想出了答案：我必须申报 spring.jpa.generate-ddl=true 在应用程序属性中也是如此。这样就可以用正确的列正确地创建指定的表

请在url中附加一些属性（如果要自动生成数据库）

  1. spring.datasource.url=jdbc:mysql://localhost:3306/espersdb?createDatabaseIfNotExist=true   
  3. spring.jpa.hibernate.ddl-auto=update
  5. @Entity
  6. @Data
  7. @NoArgsConstructor
  8. @AllArgsConstructor
  9. @Table(name="User")    // missing in your code
  10. public class User {
  11. //blah blah
  12. }
