找不到類型驗證器：java.lang.Long：沒有驗證器可以找到的類型：java.lang.Long

我有一個對象類，除了Id以外沒有必需的字段。這裏是代碼：找不到類型驗證器：java.lang.Long：沒有驗證器可以找到的類型：java.lang.Long

Entity 
@XmlRootElement 
@Table(name = "T_HOST_SPEC") 
@Cacheable(false) 
@NamedQueries({ 
    @NamedQuery(name = HostSpec.FIND_ALL, query = "SELECT m FROM HostSpec m") 
    ,@NamedQuery(name = HostSpec.FIND_BY_IP_CONTEXT_PATH_PORT, query = "SELECT m FROM HostSpec m WHERE m.ip = :ip AND m.contextPath =:contextPath AND m.port =:port ")}) 
public class HostSpec extends AbstractEntity { 



    @Id 
    @SequenceGenerator(name = "HOST_SPEC_SEQUENCE_GENERATOR", sequenceName = "HOST_SPEC_SEQ", initialValue = 1, allocationSize = 1) 
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "HOST_SPEC_SEQUENCE_GENERATOR") 
    @XmlElement(name = "id") 
    @NotNull 
    @Column(name = "ID", nullable = false) 
    private Long id; 

    @Size(max =200) 
    @Column(name = "APP_NAME",length = 25) 
    @XmlElement(name = "APP_NAME") 
    private String appName; 

    @Size(max =1000) 
    @Column(name = "APP_SERVER_INFO",length = 25) 
    @XmlElement(name = "APP_SERVER_INFO") 
    private String serverInfo; 

    @Size(max =100) 
    @Column(name = "CONTEXT_PATH",length = 25) 
    @XmlElement(name = "CONTEXT_PATH") 
    private String contextPath; 

    @Size(max =255) 
    @Column(name = "BUILD_DATE",length = 25) 
    @XmlElement(name = "BUILD_DATE") 
    private String buildDate; 

    @Size(max =4000) 
    @Column(name = "DESCRIPTION",length = 25) 
    @XmlElement(name = "DESCRIPTION") 
    private String description; 


    @Size(max =50) 
    @Column(name = "IP",length = 25) 
    @XmlElement(name = "IP") 
    private String ip; 

    @Size(max =200) 
    @Column(name = "MODULE_NAME",length = 25) 
    @XmlElement(name = "MODULE_NAME") 
    private String moduleName; 

    @Size(max =100) 
    @Column(name = "NAME",length = 25) 
    @XmlElement(name = "NAME") 
    private String name; 

    @Size(max = 10) 
    @XmlElement(name = "PORT") 
    @Column(name = "PORT") 
    private Long port; 

    @Size(max =20) 
    @Column(name = "PROTOCOL",length = 25) 
    @XmlElement(name = "PROTOCOL") 
    private String protocol; 


    @Size(max = 10) 
    @XmlElement(name = "VERSION_CODE") 
    @Column(name = "VERSION_CODE") 
    private Long versionCode; 

    @Size(max =100) 
    @Column(name = "VERSION_NAME",length = 25) 
    @XmlElement(name = "VERSION_NAME") 
    private String versionName; 

    @Size(max =100) 
    @Column(name = "VIRTUAL_SERVER_NAME",length = 25) 
    @XmlElement(name = "VIRTUAL_SERVER_NAME") 
    private String serverName; 

//getters & setters

，當我嘗試運行它，這個例外是拋出： javax.validation.UnexpectedTypeException：HV000030：沒有驗證可以爲類型中找到：java.lang.Long中請幫助

您可以嘗試從屬性'port'和'versionCode'中刪除'@Size（max = 10）'？ –

@ArnaudDenoyelle - 非常感謝。這解決了我的問題 –

好吧，我爲未來的谷歌搜索答案然後。 –

@Size不適用於Long型（在這種情況下，您應該使用@Max）。

因此，則應該與相應的@Max註釋的字段port和versionCode

取代@Size(max = 10)據的Javadoc，@Size可以在以下類型一起使用：

字符串（字符串長度evaludated）
藏品（收藏尺寸被評估）
地圖（地圖尺寸被評估）
陣列（評估陣列長度）
空元素被視爲有效。
