Question

我正在使用Flex 3.5，BlazeDS 3.2.0.3978和EJB3作为后端。有两个RPC对问题很重要。第一个调用将获得ThirdParty对象的列表，这很好。第二个调用发生在用户单击ThirdParty时，将检索此对象（延迟集合）的详细信息。返回单个对象，其中大多数字段已序列化。我说的最多，因为出于某种原因，4个布尔字段没有被序列化，默认情况下会通过flex设置为false。

这是java bean：

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;
    }
}

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 
    {
    }
}

注意：为方便起见，我省略了import语句。

我已将blazeDS日志设置为调试和所有字段，但输出中显示了这些布尔值。接下来，我尝试逐步完成序列化过程，但很容易迷失在那里。

Answer 1

您的java类没有缺少字段的getter。如果要传递字段，则序列化程序需要获取字段。

Answer 2

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

    public boolean isAuthForConsignments() {
        return authForConsignments;
    }
 }

您可以尝试将setter更改为原始布尔值吗？类型是不一致的：getter中的原语和setter中的包装器。

即使私有var设置为包装器布尔值，它也应该同时将getter和setter设置为原始布尔值。

但是对于其他类型的情况，你应该使用get和set配对 - 包括字符串。

Answer 3

也许'是' - 方法无法识别？您应该尝试在'get'-Methods中重命名它们。

为什么BlazeDS没有序列化某些字段？
