我挣扎了3天以来与以下问题。我即将在大学里为我的班级做一个项目，使用Sping Boot ，JPA和h2数据库作为一个活动网站。
现在唯一的问题是，我似乎无法摆脱这个错误，以便能够自动创建我的表...
这里是我的文件概述：
NewEvent.java实体）

package com.projekt.projekt;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "Event", schema="EVENT")
public class NewEvent {

u/Id
u/GeneratedValue(strategy = GenerationType.IDENTITY)
public Long eventID;
u/Column(name = "id")
private String cid;
u/Column(name = "title")
private String ctitle;
u/Column(name = "location")
private String clocation;
u/Column(name = "email")
private String cemail;
u/Column(name = "phone")
private String cphone;
u/Column(name = "date")
private String cdate;
u/Column(name = "time")
private String ctime;
u/Column(name = "description")
private String cdescription;
u/Column(name = "test")
private String test;

private String title;
private String location;
private String email;
private String phone;
private java.sql.Date date;
private java.sql.Time time;
private String description;

public Long getEventID() {
return eventID;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getLocation() {
return location;
}
public void setLocation(String location) {
this.location = location;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public java.sql.Date getDate() {
return date;
}
public void setDate(java.sql.Date date) {
this.date = date;
}
public java.sql.Time getTime() {
return time;
}
public void setTime(java.sql.Time time) {
this.time = time;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}

}

NewEventRepository.java repository）：

package com.projekt.projekt;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

u/Repository
public interface NewEventRepository extends JpaRepository<NewEvent, Long> {
// Add custom query methods if needed
}

ProjektApplication.java(Application File):

Sping Boot JPA不是一个托管类型的错误让我无法继续我的项目，你现在基本上可以忽略php，因为它不会被使用，也不会被删除，因为我的小组做了它。
我会很高兴，如果任何人都可以帮助我摆脱这个错误“不受管理的类型”不知何故，我觉得如果尝试了几乎每一个教程和resources我发现。我会很高兴，如果任何人都可以帮助我摆脱这个错误“不受管理的类型”不知何故，我觉得如果尝试了几乎每一个教程和resources我发现。
我试着折射，改变进口，从头开始设置新的，遵循教程，给它新的名字，三重检查包。下面是我现在得到的一个错误消息示例：

Caused by: java.lang.IllegalArgumentException: Not a managed type: class com.projekt.projekt.NewEvent
