Hibernate搜索4.5 Alpha 1無法在java.lang.Byte中猜出FieldBridge爲id

我在將EAR項目部署到Wildfly 8 beta1時遇到問題。該項目使用Hibernate Search 4.5 Alpha 1.有一些實體索引。該項目生成良好，但部署時引發異常：無法在java.lang.Byte中猜出FieldBridge作爲id。我嘗試禁用所有hibernate搜索註釋，但仍然出現異常。接縫是一個錯誤。有什麼建議麼？Hibernate搜索4.5 Alpha 1無法在java.lang.Byte中猜出FieldBridge爲id

這是再現異常實體的例子：

@Entity 
@Table(name = "flow") 
public class Flow implements java.io.Serializable { 

private static final long serialVersionUID = 3556704047257784867L; 
private Byte id; 
private String name; 
private String description; 

public Flow() { 
} 

public Flow(String name) { 
    this.name = name; 
} 

public Flow(String name, String description) { 
    this.name = name; 
    this.description = description; 
} 

@Id 
@GeneratedValue(strategy = IDENTITY) 
@Column(name = "id", unique = true, nullable = false) 
public Byte getId() { 
    return this.id; 
} 

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

@Column(name = "name", nullable = false, length = 60) 
@NotNull 
@Length(max = 60) 
public String getName() { 
    return this.name; 
} 

public void setName(String name) { 
    this.name = name; 
} 

@Column(name = "description", length = 400) 
@Length(max = 400) 
public String getDescription() { 
    return this.description; 
} 

public void setDescription(String description) { 
    this.description = description; 
}

}

如果ID從字節改爲短工作正常。 Byte沒有內置的橋接。也許這是相關的，但主要問題是爲什麼如果我沒有hibernate搜索註釋，hibernate搜索正在尋找橋樑？

也許這個錯誤是有關：https://hibernate.atlassian.net/browse/HSEARCH-1447 – Tvori

你能請附上沒有實體的HSEARCH -1447錯誤？如果沒有觸發問題的映射實體的例子，我認爲我無法修復它。 – Sanne

我編輯了這個問題並添加了一個拋出異常的實體。 – Tvori

一個快速的解決方法 - 可以創建一個ByteBridge：

public class ByteBridge extends NumberBridge implements Serializable { 
public Object stringToObject(String stringValue) { 
    if (StringHelper.isEmpty(stringValue)) return null; 
    return Byte.valueOf(stringValue); 
} 
}

，然後添加批註實體：

@FieldBridge(impl=....)

我嘗試定製FieldBridge路線，但原來Hibernate Search的字節轉換字段添加到FieldBridge之前的Integer對象。這意味着只需添加正常IntegerBridge工作解決該問題：

@FieldBridge(impl = IntegerBridge.class)
