在Springboot中开始，下面的包找不到。我已经添加了两个依赖项，单击Maven并重新加载项目，并尝试重建项目，但仍然没有成功。可能是一个简单的修复。

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class ExampleEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
}

下面是我的pom.xml：

        <dependency>
