实体类是

import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;


@Entity
public class Employee {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    private String name;
    private String phone;

}

属性文件是

我该如何解决这个问题？

Answer 1

我发现你的项目在我这边运行良好，你可能会尝试在你这边工作。

尝试更改为＜code＞spring.datasource.drivercassname=com.mysql.jdbc.Driver

从主类中删除@ComponentScan（），然后将@SpringBootApplication留在那里。

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