无法从实体Spring Boot生成表

Question

// class Application
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;

@EntityScan("sb.entity")
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

// class Entity
package sb.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name = "category")
public class CategoryEntity {
    
    @Column(name = "name")
    private String name;
    
    @Column(name = "code")
    private String code;

}

// application.properties
server.port=8081

spring.datasource.url = jdbc:mysql://localhost:3306/springboot_database
spring.datasource.username = root
spring.datasource.password = hoa123456
spring.jpa.hibernate.ddl-auto = create-drop 

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

这是控制台：我搜索了overstack，但我只是添加了spring-boot-starter-data-jpa。

请确保您已将应用程序类包正确放置在包下。例如，如果您的application.java（它有main）在com.sb下，那么sb.java实体类应该在com.sb包下。

com.sb-->application.java

com.sb.enity-->CategoryEntity.java
