hibernate - JPA @Embedded 注释在 netbeans 中标记为错误

Question

在 NETBEANS 中

错误显示在第2行：

 @Embedded    
    public SchoolDetails getSchoolDetails() {
    return schoolDetails;
     }

基本属性只能是以下类型：Java 原始类型、原始类型的包装器、String、java.math.BigInteger、java.math.BigDecimal、java.util.Date、java.util.Calendar、java.sql.Date 、java.sql.Time、java.sql.TimeStamp、byte[]、Byte[]、char[]、Character[]、枚举或任何可序列化类型。嵌入

请注意，类如下

package com.chapter3;

import java.io.Serializable;
import javax.persistence.Embedded;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;


@Entity
public class School  {

    private int schoolId;
    private String schooleName;
    private SchoolDetails schoolDetails;

    @Embedded    
    public SchoolDetails getSchoolDetails() {
        return schoolDetails;
    }

    public void setSchoolDetails(SchoolDetails schoolDetails) {
        this.schoolDetails = schoolDetails;
    }

    @Id
    @GeneratedValue
    public int getSchoolId() {
        return schoolId;
    }

    public void setSchoolId(int schoolId) {
        this.schoolId = schoolId;
    }

    public String getSchooleName() {
        return schooleName;
    }

    public void setSchooleName(String schooleName) {
        this.schooleName = schooleName;
    }
}

package com.chapter3;

import javax.persistence.Embeddable;

@Embeddable
public class SchoolDetails {

    private String schoolAddress;
    private boolean isPublicSchool;
    private int studentCount;

    public boolean isIsPublicSchool() {
        return isPublicSchool;
    }

    public void setIsPublicSchool(boolean isPublicSchool) {
        this.isPublicSchool = isPublicSchool;
    }

    public String getSchoolAddress() {
        return schoolAddress;
    }

    public void setSchoolAddress(String schoolAddress) {
        this.schoolAddress = schoolAddress;
    }

    public int getStudentCount() {
        return studentCount;
    }

    public void setStudentCount(int studentCount) {
        this.studentCount = studentCount;
    }
}

问题是netbeans中的一个错误

网豆问题

并且我必须实现可序列化接口的解决方案并且错误消失了。
