java - Castor:如何映射 Java 层次结构

Question

我在映射层次结构时遇到了 Java-Castor 问题。感谢您抽出时间。

我有这个 XML 文件:

<RESULT>
  <RESULTCODE>OK</RESULTCODE>
  <ERRORS />
  <COMPANIES>
    <COMPANY VD="107795641" NAME="COMPANYA"
    RATING="" CIF="ABCD3435" ID="7671" NUM="0" />
    <COMPANY VD="102167561" NAME="COMPANYB"
    RATING="" CIF="ABCD1234" ID="6642" NUM="1" />
  </COMPANIES>
</RESULT>

这个 Java 层次结构:

public class RentedWSResult 
{
    private boolean success;

    private List<RentedWSResultError> errors;
}

public class GetCompaniesRentedWSResult extends RentedWSResult 
{
    private List<RentedCompany> rentedCompanies;
}

还有这些 Castor 映射:

<mapping>
    <class name="RentedWSResult">
    <map-to xml="RESULT" />
    <field name="success" type="string" handler="BooleanStringHandler">
        <bind-xml name="RESULTCODE" />
    </field>
    <field name="errors" type="RentedWSResultError" collection="arraylist"> 
        <bind-xml name="ERROR" location="ERRORS" />
    </field>
    </class>
</mapping>

<mapping>
    <include href="RentedWSResultMarshallConfig.xml"/>
    <class name="GetCompaniesRentedWSResult" >
    <field name="rentedCompanies" type="RentedCompany" collection="arraylist">
        <bind-xml name="COMPANY" location="COMPANIES" />
    </field>
    </class>
</mapping>

它不起作用，出现此错误:

Unable to find FieldDescriptor for 'COMPANIES' in ClassDescriptor of RESULT

映射文件中的类之间没有关系。

根据您提供的信息，我整理了一个有效的映射。它假定您的 RentedWSResult 是其他元素的容器类。

<mapping>
    <include href="GetCompaniesRentedWSResultBinding.xml"/>

    <class name="RentedWSResult">
        <map-to xml="RESULT" />
        <field name="success" type="string">
            <bind-xml name="RESULTCODE" />
        </field>

        <field name="rentedCompanies" type="GetCompaniesRentedWSResult"> 
            <bind-xml name="COMPANIES" />
        </field>
    </class>

 </mapping>

<mapping>
    <class name="GetCompaniesRentedWSResult" >
        <field name="rentedCompanies" type="RentedCompany" collection="arraylist">
            <bind-xml name="COMPANY" />
        </field>
    </class>

    <class name="RentedCompany" >
    <field name="vd" type="string">
            <bind-xml name="vd" node="attribute" />
        </field>

        <field name="name" type="string">
            <bind-xml name="name" node="attribute"/>
        </field>

        <field name="rating" type="string">
            <bind-xml name="rating" node="attribute"/>
        </field>

    </class>
</mapping>
