为什么BlazeDS不能序列化一些字段？

我使用Flex 3.5，BlazeDS 3.2.0.3978和EJB3作为后端。有两个RPC对于这个问题很重要。第一次调用将获得ThirdParty对象的列表，这工作正常。第二次调用发生在用户点击ThirdParty时，该对象的细节（懒惰集合）被检索。大多数字段序列化后返回一个对象。我说得最多，因为出于某种原因，4个布尔字段没有被序列化，并且默认情况下通过flex被置于false。为什么BlazeDS不能序列化一些字段？

这里是java bean的：

 
package com.rekencentra.svc.cfos.model.security; 


@Entity 
@Table(
    name = "AUTH_THP", 
    uniqueConstraints = { 
     @UniqueConstraint(columnNames={"THP_ID", "OTH_THP_ID"}) 
    } 
) 
@NamedQueries({ 
    @NamedQuery(
     name="allAuthorizationsForThp", 
     query="SELECT DISTINCT c FROM AuthorisationThirdParty c " + 
       " LEFT JOIN FETCH c.otherThirdParty thp" + 
       " LEFT JOIN FETCH thp.goodRegulation" + 
       " WHERE c.thirdParty.id = :id" + 
       " AND c.authValidFrom = sysdate()" 
      )} 
) 

@SequenceGenerator(name="seqSerialId", sequenceName="SEQ_AUTH_THP") 
public class AuthorisationThirdParty extends BusinessObject { 

    private static final long serialVersionUID = -4187381385945255374L; 

    @ManyToOne(fetch=FetchType.LAZY, cascade = {CascadeType.REFRESH}) 
    @JoinColumn(name="THP_ID", nullable=false) 
    private ThirdParty thirdParty; 

    @ManyToOne(fetch=FetchType.EAGER, cascade = {CascadeType.REFRESH}) 
    @JoinColumn(name="OTH_THP_ID", nullable=false) 
    private ThirdParty otherThirdParty; 

    @Column(name="ICT_F", nullable=false) 
    private Boolean authForTemplates; 

    @Column(name="ICN_F", nullable=false) 
    private Boolean authForConsignments; 

    @Column(name="SC_F", nullable=false) 
    private Boolean authForSalesContracts; 

    @Column(name="PC_F", nullable=false) 
    private Boolean authForPurchaseContracts; 

    @Column(name="FROM_DATE", nullable=true) 
    @Temporal(TemporalType.DATE) 
    private Date authValidFrom; 

    @Column(name="UNTIL_DATE", nullable=true) 
    @Temporal(TemporalType.DATE) 
    private Date authValidTo; 

    public ThirdParty getThirdParty() { 
     return thirdParty; 
    } 

    public void setThirdParty(ThirdParty thirdParty) { 
     this.thirdParty = thirdParty; 
    } 

    public ThirdParty getOtherThirdParty() { 
     return otherThirdParty; 
    } 

    public void setOtherThirdParty(ThirdParty otherThirdParty) { 
     this.otherThirdParty = otherThirdParty; 
    } 

    public Date getAuthValidFrom() { 
     return authValidFrom; 
    } 

    public void setAuthValidFrom(Date authValidFrom) { 
     this.authValidFrom = authValidFrom; 
    } 

    public Date getAuthValidTo() { 
     return authValidTo; 
    } 

    public void setAuthValidTo(Date authValidTo) { 
     this.authValidTo = authValidTo; 
    } 

    public void setAuthForTemplates(Boolean authForTemplates) { 
     this.authForTemplates = authForTemplates; 
    } 

    public boolean isAuthForTemplates() { 
      return authForTemplates; 
    } 

    public void setAuthForConsignments(Boolean authForConsignments) { 
     this.authForConsignments = authForConsignments; 
    } 

    public boolean isAuthForConsignments() { 
     return authForConsignments; 
    } 

    public void setAuthForSalesContracts(Boolean authForSalesContracts) { 
     this.authForSalesContracts = authForSalesContracts; 
    } 

    public boolean isAuthForSalesContracts() { 
     return authForSalesContracts; 
    } 

    public void setAuthForPurchaseContracts(Boolean authForPurchaseContracts) { 
     this.authForPurchaseContracts = authForPurchaseContracts; 
    } 

    public boolean isAuthForPurchaseContracts() { 
     return authForPurchaseContracts; 
    } 
}

和相应的Flex类：

 
package com.rekencentra.ifb.cfos.model.dto.security 
{ 
    [Bindable] 
    [ExcludeClass] 
    internal class AuthorisationThirdPartyBase extends BusinessObject 
    { 
     public var thirdParty:ThirdParty; 
     public var otherThirdParty:ThirdParty; 
     public var authForTemplates:Boolean; // missing ser. 
     public var authForConsignments:Boolean; //missing ser. 
     public var authForSalesContracts:Boolean; //missing ser. 
     public var authForPurchaseContracts:Boolean; //missing ser. 
     public var authValidFrom:Date; 
     public var authValidTo:Date; 
    } 
} 

package com.rekencentra.ifb.cfos.model.dto.security 
{ 
    [Bindable] 
    [RemoteClass(alias="com.rekencentra.svc.cfos.model.security.AuthorisationThirdParty")] 
    public class AuthorisationThirdParty extends AuthorisationThirdPartyBase 
    { 
    } 
}

注：我已经离开了为了方便import语句。

我已经设置blazeDS日志记录调试和所有领域，但这些布尔值显示在输出中。接下来，我尝试了一下序列化过程，但在那里迷路很容易。

你的java类没有getters为缺少的字段。如果序列化程序要通过，则需要获取字段。

很好，这个固定它。我认为布尔的getter可以是遵循javabean规范的isXXX。 – joeriMJ 2010-09-07 10:27:44

我一直认为使用公有字段而不是getter和setter的数据传输对象是序列化到BlazeDS的更直接的方式。诚然，复制所有字段会导致性能下降，但不会让数据访问层泄漏到表示层中，并且乍一看看字段名称中的不匹配值得投资。 – weltraumpirat 2012-11-26 07:14:09

也许'is'-Methods未被识别？你应该尝试在'get'-Methods中重命名它们。

public void setAuthForConsignments(Boolean authForConsignments) { 
     this.authForConsignments = authForConsignments; 
    } 

    public boolean isAuthForConsignments() { 
     return authForConsignments; 
    } 
}

你可以尝试改变setter为原始布尔值吗？类型不一致：getter中的primitive和setter中的wrapper。

即使私有变量设置为包装布尔值，它也应该将getter和setter都设置为原始布尔值。

但对于其他类型的情况，您应该使用get和set配对 - 包括字符串。
