Question

我有以下java代码：

public class SomeType{
    private String firstName;
    private java.util.Date dob;
    private Long someID;
    private Double firstAmount;
    private Double secondAmount;
    private java.util.Date beginDate;
    private java.util.Date endDate;
    // setters and getters
}

对于上面的代码，以下是xml代码，它正常工作。

    <xs:complexType name = "SomeType">
           <xs:sequence>
              <xs:element name = "firstName" type = "xsd:String"/>
              <xs:element name = "dob" type = "xsd:date"/>
              <xs:element name = "someID" type = "xsd:long"/>
              <xs:element name = "firstAmount" type = "xsd:double"/>
              <xs:element name = "secondAmount" type = "xsd:double"/>
              <xs:element name = "beginDate" type = "xsd:date"/>
              <xs:element name = "endDate" type = "xsd:date"/>
           </xs:sequence>
        </xs:complexType>

现在我在java代码中添加了以下字段：

List<Object[]> records = new ArrayList<Object[]>();

我从数据库中选择4个值（列），即“firstAmount”，“secondAmount”，“beginDate”和“endDate”，query.list（）返回List<Object[]>（即元组有4列）。我正在“记录”（字段）中存储所有数据（在类型转换和迭代对象[]列表之后）。考虑到我们必须将此Field传递给架构中的其他层，如何为此Field（List<Object[]＆gt;记录）编写xsd代码。

提前谢谢。

Answer 1

据我了解，您需要更换这部分XSD

<xs:element name = "firstAmount" type = "xsd:double"/>
<xs:element name = "secondAmount" type = "xsd:double"/>
<xs:element name = "beginDate" type = "xsd:date"/>
<xs:element name = "endDate" type = "xsd:date"/>

具有如下的复杂类型

  <xs:element name="records">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="field" maxOccurs="unbounded" minOccurs="0">
          <xs:complexType>
            <xs:sequence>
              <xs:element name = "firstAmount" type = "xsd:double"/>
              <xs:element name = "secondAmount" type = "xsd:double"/>
              <xs:element name = "beginDate" type = "xsd:date"/>
              <xs:element name = "endDate" type = "xsd:date"/>
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

Answer 2

<xs:complexType name = "SomeType">
       <xs:sequence>
          <xs:element name = "firstName" type = "xsd:String"/>
          <xs:element name = "dob" type = "xsd:date"/>
          <xs:element name = "someID" type = "xsd:long"/>
          <xs:element name = "firstAmount" type = "xsd:double"/>
          <xs:element name = "secondAmount" type = "xsd:double"/>
          <xs:element name = "beginDate" type = "xsd:date"/>
          <xs:element name = "endDate" type = "xsd:date"/>
          <xs:element name = "records" type = "recordsType"/>
       </xs:sequence>
    </xs:complexType>
    <xs:complexType name = "recordsType">
     <xs:sequence>
      <xs:element name = "record" type = "recordType" minOccurs="0" maxOccurs="unbounded"/><!-- a list or 0 or any number of records -->
     </xs:sequence>
    </xs:complexType>
    <xs:complexType name = "recordType">
     <!-- write the internal structure of your record element -->
    </xs:complexType>
