我在saving object

实际上这个assocClassSubjectPKId在我的实体类中是整数，即使它的要求类似于（期望的类型= java.lang.Integer）

请查看我的实体类

@Entity
@Table(name = "assoc_class_subject", catalog = "campus_guru_01")
public class AssocClassSubject implements java.io.Serializable {

    private AssocClassSubjectId id;
    private MasterCampusClass masterCampusClass;
    private MasterSubject masterSubject;
    private Integer assocClassSubjectPKId;




    public AssocClassSubject() {
    }


    public AssocClassSubject(AssocClassSubjectId id, MasterCampusClass masterCampusClass, MasterSubject masterSubject) {
        this.id = id;
        this.masterCampusClass = masterCampusClass;
        this.masterSubject = masterSubject;
    }

    @EmbeddedId

    @AttributeOverrides({ @AttributeOverride(name = "classId", column = @Column(name = "class_id", nullable = false)),
            @AttributeOverride(name = "subjectId", column = @Column(name = "subject_id", nullable = false)),
            @AttributeOverride(name = "subjectOrder", column = @Column(name = "subject_order")),
            @AttributeOverride(name = "subjectExclude", column = @Column(name = "subject_exclude", length = 45)) })




    @Id 
    @GeneratedValue(strategy = IDENTITY)  

    @Column(name = "class_subject_mapping_id", unique = true, nullable = false)

    public Integer getAssocClassSubjectPKId() {
    return assocClassSubjectPKId;
}
    public void setAssocClassSubjectPKId(Integer assocClassSubjectPKId) {
        this.assocClassSubjectPKId = assocClassSubjectPKId;
    }


    public AssocClassSubjectId getId() {
        return this.id;
    }

    public void setId(AssocClassSubjectId id) {
        this.id = id;
    }

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "class_id", nullable = false, insertable = false, updatable = false)
    public MasterCampusClass getMasterCampusClass() {
        return this.masterCampusClass;
    }

    public void setMasterCampusClass(MasterCampusClass masterCampusClass) {
        this.masterCampusClass = masterCampusClass;
    }

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "subject_id", nullable = false, insertable = false, updatable = false)
    public MasterSubject getMasterSubject() {  
        return this.masterSubject;
    }

    public void setMasterSubject(MasterSubject masterSubject) {
        this.masterSubject = masterSubject;
    }

}

为什么它甚至是整数给出这个例外？

我做错了什么？无法追踪它。请帮帮我。

谢谢你！

修改

任何人都可以告诉这一行究竟是什么意思

IllegalArgumentException occurred while calling setter for property [com.rasvek.cg.entity.AssocClassSubject.assocClassSubjectPKId(expected type = java.lang.Integer)]; target = [com.rasvek.cg.entity.AssocClassSubject@1aeba13], property value = [POST_INSERT_INDICATOR]

我通过改变实体类来解决它
