Spring hibernate映射

Question

最近，我在一個基於spring + hibernate的項目中工作。我有兩個實體（ProspectMaster，ProspectWorkshopMap），ProspectMaster與ProspectWorkshopMap有兩個很多的關係，當我添加一個Prospect時，我得到以下錯誤

javax.validation.UnexpectedTypeException：沒有驗證器可以找到類型：java.lang。整數

波紋管是我的代碼

@Entity 
public class ProspectMaster { 
    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private int              prospectID; 

    private String             companyName; 

    @OneToMany(fetch = FetchType.LAZY, cascade=CascadeType.ALL) 
    @JoinColumn(name="prospectID") 
    private Set<ProspectWorkshopMap> prospectWorkshopMap   = new HashSet<ProspectWorkshopMap>(0); 



    public Set<ProspectWorkshopMap> getProspectWorkshopMap() { 
     return prospectWorkshopMap; 
    } 

    public void setProspectWorkshopMap(Set<ProspectWorkshopMap> prospectWorkshopMap) { 
     this.prospectWorkshopMap = prospectWorkshopMap; 
    } 




    public String getCompanyName() { 
     return companyName; 
    } 

    public void setCompanyName(String companyName) { 
     this.companyName           = companyName; 
    } 

} 

和另一

@Entity 
public class ProspectWorkshopMap { 
    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private int               prospectWorkshopID; 


    @Column(columnDefinition = "int default 0") 
    private int               iPadProspectWorkshopID; 


    @OneToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "prospectCreatedFromID") 
    private ProspectCreatedFromRef          prospectCreatedFromRef; 



    private String              address; 

    @Length(max = 50) 
    private String              email; 

    private String              deviceID; 

    @Length(max = 20)

     this.address             = address; 
    } 

    public String getEmail() { 
     return email; 
    } 

    public void setEmail(String email) { 
     this.email              = email; 
    } 

    public String getDeviceID() { 
     return deviceID; 
    } 

    public void setDeviceID(String deviceID) { 
     this.deviceID             = deviceID; 
    } 

    public int getDirectNumber() { 
     return directNumber; 
    }

     this.directNumber            = directNumber; 
    } 

    public int getIsMainWorkshop() {

    } 

    public void setIsMainWorkshop(int isMainWorkshop) { 
     this.isMainWorkshop            = isMainWorkshop; 
    } 

    public Date getCreatedDate() { 
     return createdDate; 
    } 

    public void setCreatedDate(Date createdDate) { 
     this.createdDate            = createdDate; 
    } 

    public Date getUpdatedDate() { 
     return updatedDate; 
    } 

    public void setUpdatedDate(Date updatedDate) { 
     this.updatedDate            = updatedDate; 
    } 

    public int getCreatedBy() { 
     return createdBy; 
    } 

    public void setCreatedBy(int createdBy) { 
     this.createdBy             = createdBy; 
    } 

    public int getUpdatedBy() { 
     return updatedBy; 
    } 

    public void setUpdatedBy(int updatedBy) { 
     this.updatedBy             = updatedBy; 
    } 

    public int getIsDeleted() {

    } 

    public void setIsDeleted(int isDeleted) {

    } 

    /**

    */ 
    public long getUtcCreatedDateTimestamp() { 
     return utcCreatedDateTimestamp; 
    } 

    /**

    */ 
    public void setUtcUpdatedDateTimestamp(long utcUpdatedDateTimestamp) { 
     this.utcUpdatedDateTimestamp = utcUpdatedDateTimestamp; 
    } 
} 

救我做

ProspectMaster prospect= new ProspectMaster(); 
     prospect.setCompanyName("Randem IT"); 
     ProspectWorkshopMap prospectWorkshopMap = new ProspectWorkshopMap(); 
     prospectWorkshopMap.setAddress("sydneyaustralia"); 
     prospectWorkshopMap.setCreatedBy(1); 
     prospectWorkshopMap.setUpdatedBy(1); 
     prospectWorkshopMap.setDirectNumber(1234567890); 
     prospectWorkshopMap.setEmail("testwork0007@gmail.com"); 
     prospectWorkshopMap.setIsMainWorkshop(1); 
     prospectWorkshopMap.setUtcCreatedDateTimestamp(122335); 
     prospectWorkshopMap.setUtcUpdatedDateTimestamp(86998989); 
     ProspectCreatedFromRef proRef= new ProspectCreatedFromRef(); 
     proRef.setProspectCreatedFromID(1); 
     prospect.getProspectWorkshopMap().add(prospectWorkshopMap); 
SessionFactory. getCurrentSession().saveOrUpdate(prospect); 

我犯錯了嗎？任何人都可以請幫忙。有沒有映射問題？

註釋@Length用於驗證字符串。在你的代碼中，你使用它作爲int字段。例如，使用@Max來驗證您的數值。
