Spring Boot JPA @Entity 未定义为 bean

Question

我无法运行我的 Spring Boot 应用程序，因为 JPA 存在问题。但我无法找到问题并解决它。我搜索了几个堆栈溢出主题的解决方案，但没有一个解决方案对我有帮助。我定义了以下模型：

package xyz.blackmonster.window.models;

import java.util.List;

import javax.persistence.CascadeType;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.FetchType;

import javax.persistence.GeneratedValue;

import javax.persistence.Id;

import javax.persistence.OneToMany;

import javax.persistence.OneToOne;

import org.hibernate.annotations.GenericGenerator;

/**

 * Window order

 */

@Entity

public class Order {

    @Id

    @GeneratedValue(generator = "system-uuid")

    @GenericGenerator(name = "system-uuid", strategy = "uuid2")

    private String uuid;

    @OneToMany(fetch = FetchType.EAGER, mappedBy = "order", cascade = CascadeType.ALL)

    private List<Window> windows;

    @OneToOne(fetch = FetchType.EAGER, mappedBy = "order", cascade = CascadeType.ALL)

    private Service service;

    @OneToOne(fetch = FetchType.EAGER, mappedBy = "order", cascade = CascadeType.ALL)

    private Cost cost;

    @Column(name = "email")

    private String email;

    public String getUuid() {

        return uuid;

    }

    public void setUuid(String uuid) {

        this.uuid = uuid;

    }

    public List<Window> getWindows() {

        return windows;

    }

    public void setWindows(List<Window> windows) {

        this.windows = windows;

    }

    public Service getService() {

        return service;

    }

    public void setService(Service service) {

        this.service = service;

    }

    public Cost getCost() {

        return cost;

    }

    public void setCost(Cost cost) {

        this.cost = cost;

    }

    public String getEmail() {

        return email;

    }

    public void setEmail(String email) {

        this.email = email;

    }

}

如您所见，实体使用了正确的导入 (javax.persistence.Entity)。我指出这一点，因为这是我遇到的解决方案之一。
