“调用getter of”发生IllegalArgumentException异常。同时运行SINGLE_TABLE继承策略的条件

本文介绍了“调用getter of”发生IllegalArgumentException异常。同时运行SINGLE_TABLE继承策略的条件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在尝试使用hibernate Criteria从数据库中列出对象时出现此错误，该标准使用简单的限制进行了修饰

  Criteria criteria = session。个createCriteria（Licence.class）; 
 criteria.add（Restrictions.eq（gym，gym.getId（）））; 
列表< License> list = criteria.list（）;

我有两个类： License 与健身房的关联。这两个类扩展了 DataModel ，它用于管理关于数据编辑的信息（创建和判断，谁和何时）。同样重要的是这两个类有 @Inheritance（strategy = InheritanceType.SINGLE_TABLE）。

我做错了什么？
解决方案
尝试使用
  criteria.add（Restrictions.eq（gym，gym））; 
  
即您将 gym 作为 criteria.add 而不是的第二个参数。gym.getId（）。
 
I have this error while trying to list objects from database with hibernate Criteria decorated with simple Restrictions
Criteria criteria = session.createCriteria(Licence.class);
criteria.add(Restrictions.eq("gym", gym.getId()));
List<Licence> list = criteria.list();

I have two classes: Licence which has an association to Gym. Those two classes are extending DataModel which is for managing information about data edition - (creation and etition, who and when). What is also important that those two classes have @Inheritance(strategy = InheritanceType.SINGLE_TABLE).
Licence
@Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
public class Licence extends DataModel implements Serializable {

    private Gym gym;
    private String licenceType;
    private String keyCode;
    private Date expireDate;
    private ELicenceExpiry expired;

    public Licence() {
    }

    @ManyToOne
    @JoinColumn(name="gym_id")
    public Gym getGym() {
        return gym;
    }

    public void setGym(Gym gym) {
        this.gym = gym;
    }

    @Column(name = "licence_type")
    public String getLicenceType() {
        return licenceType;
    }

    public void setLicenceType(String licenceType) {
        this.licenceType = licenceType;
    }

    @Column(name = "key_code")
    public String getKeyCode() {
        return keyCode;
    }

    public void setKeyCode(String keyCode) {
        this.keyCode = keyCode;
    }

    @Column(name = "expire_date")
    public Date getExpireDate() {
        return expireDate;
    }

    public void setExpireDate(Date expireDate) {
        this.expireDate = expireDate;
    }

    @Column(name = "expired")
    @Enumerated(EnumType.ORDINAL)
    public ELicenceExpiry getExpired() {
        return expired;
    }
    public void setExpired(ELicenceExpiry expired) {
        this.expired = expired;
    }
}

Gym
@Entity
@Inheritance(strategy= InheritanceType.SINGLE_TABLE)
public class Gym extends DataModel implements Serializable{

    private String shortName;
    private String name;
    private String nip; 
    private String street;
    private String postCode;
    private String localization;
    private String telephone;

    public Gym(){};

    @Column(name="short_name")
    public String getShortName() {
        return shortName;
    }
    public void setShortName(String shortName) {
        this.shortName = shortName;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getNip() {
        return nip;
    }
    public void setNip(String nip) {
        this.nip = nip;
    }
    public String getStreet() {
        return street;
    }
    public void setStreet(String street) {
        this.street = street;
    }
    @Column(name="post_code")
    public String getPostCode() {
        return postCode;
    }
    public void setPostCode(String postCode) {
        this.postCode = postCode;
    }
    public String getLocalization() {
        return localization;
    }
    public void setLocalization(String localization) {
        this.localization = localization;
    }
    public String getTelephone() {
        return telephone;
    }
    public void setTelephone(String telephone) {
        this.telephone = telephone;
    }
}

DataModel
@MappedSuperclass
public abstract class DataModel implements Serializable{
    protected Long id;
    protected String editor;
    protected Date editDate;
    protected Time editTime;
    protected int dataState;

    @GeneratedValue
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getEditor() {
        return editor;
    }
    public void setEditor(String editor) {
        this.editor = editor;
    }
    @Column(name="edit_date")
    public Date getEditDate() {
        return editDate;
    }
    public void setEditDate(Date editDate) {
         this.editDate = editDate;
    }
    @Column(name="edit_time")

         return dataState;
    }
    public void setDataState(int dataState) {
        this.dataState = dataState;
    }
 }

What I am doing wrong?
 解决方案 
Try to use
criteria.add(Restrictions.eq("gym", gym));

i.e. you put gym as second argument of criteria.add instead of gym.getId().
