NPE in Hibernate 4

时间：2014-08-20 22:34:44

标签： spring hibernate hibernate-mapping spring-orm

我们正在将所有第三方库升级到最新版本，主要与Spring 4和Hibernate 4相关。修复所有编译问题后，我遇到了Jboss 4.2.3中的部署问题。当我调试Hibernate代码时，我想出了异常的位置。但不确定为什么会导致NPE。

当referenceEntity.getKey（）为org.hibernate.cfg.Ejb3JoinColumn.java中的以下对象返回null时，会发生异常。这适用于Hibernate 3.3.0和Spring 3.2.2 

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToOne;
import javax.persistence.Table;

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;


@Entity
@Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@Table(name = "lk_mc_instrument_type")
public class MCInstrumentType {

    @Id
    @OneToOne(mappedBy = "instrumentType" )
    @JoinColumn(name="mc_instrument_type_code" )
    private String code;

    private String description;

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getDescription() {
        return description;

    public void setDescription(String description) {

    }

    public String toString(){

尝试从referencedColumnName

中删除EarlyCloseInstrument 
    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn (name = "INSTRUMENT_TYPE_CODE", updatable = false, insertable = false)
    private MCInstrumentType instrumentType;
