我正在尝试使用 Jaxb 从 xml 请求中创建一个 Java 对象，但我对 jaxb 的有限了解阻碍了我的发展。我以前做过这个，但它是简单的 XML 文档，只使用基本元素，如
<RootElement>
<Bookname>Moby Dick</Bookname>
<BookCode>1</BookCode>
</RootElement>
但是现在我有一个更复杂的 xml 文件，如果能帮助我开始创建这个对象，我将不胜感激。我想我将不得不使用某种列表以及@Xmlattribute，但现在我很困惑。任何帮助将不胜感激!我希望我不只是想得太多了。示例 XML 如下所示:
<?xml version="1.0"?>
<CRMMessage language="en_US" currency="USD" >
<RequestSource name="Testsource" version="2" />
<RequestCode>GetTest</RequestCode>
<DataSet>
<DataSetColumns>
<DSColumn name="Column1" />
<DSColumn name="Column2" />
</DataSetColumns>
<Rows>
<Row>
<Col>John</Col>
<Col>Doe</Col>
</Row>
</Rows>
</DataSet>
</CRMMessage>
最佳答案
我已经为您提供了一个快速模式，这可能不是您所需要的，因为我无法从示例数据中判断它是否允许多个或某些元素等:
<xs:schema version="1.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:element name="CRMMessage">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="1" name="RequestSource">
<xs:complexType>
<xs:attribute name="Testsource" type="xs:string"/>
<xs:attribute name="version" type="xs:integer"/>
</xs:complexType>
</xs:element>
<xs:element minOccurs="1" maxOccurs="1" name="RequestCode" type="xs:string"/>
<xs:element minOccurs="1" maxOccurs="1" name="DataSet">
<xs:complexType>
<xs:all>
<xs:element minOccurs="1" maxOccurs="1" name="DataSetColumns">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="unbounded" name="DSColumn">
<xs:complexType>
<xs:attribute name="name" type="xs:string"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element minOccurs="1" maxOccurs="1" name="Rows">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="unbounded" name="Row">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="unbounded" name="Col" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:all>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="language" type="xs:string"/>
<xs:attribute name="currency" type="xs:string"/>
</xs:complexType>
</xs:element>
</xs:schema>
您应该能够以此为起点。
然后我通过 maven 插件使用 xjc 将其编译成一个类，并在我的 pom 中使用以下内容:
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.8.2</version>
<executions>
<execution>
<id>bind-crm</id>
<configuration>
<schemaDirectory>src/main/resources/</schemaDirectory>
<generatePackage>com.my.package.crm</generatePackage>
<forceRegenerate>true</forceRegenerate>
</configuration>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
</plugin>
这给了我以下代码:
