java - JAXB 内部元素被忽略

Question

我正在使用 JAXB 处理一些 XML。我不明白为什么我无法访问此标签的内部元素。

XML 片段:

<binary>
    <route>
        <payload source="SomeService" version="1.2"><![CDATA[ACAA8f///...snip...AAAAAGGAAAARAFR]]>
        </payload>
    </route>
</binary>

由此我生成了一个 XSD:

 <xsd:element name="binary">
      <xsd:complexType>
        <xsd:sequence>
          <xsd:element name="route">
            <xsd:complexType>
              <xsd:sequence>
                <xsd:element name="payload">
                  <xsd:complexType>
                    <xsd:attribute name="source" type="xsd:string" />
                    <xsd:attribute name="version" type="xsd:string" />
                  </xsd:complexType>
                </xsd:element>
              </xsd:sequence>
            </xsd:complexType>
          </xsd:element>
        </xsd:sequence>
      </xsd:complexType>
    </xsd:element>

我正在使用 maven-jaxb2-plugin 并且一切正常:

<build>
    <plugins>
      <plugin>
        <inherited>true</inherited>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.6</source>
          <target>1.6</target>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.jvnet.jaxb2.maven2</groupId>
        <artifactId>maven-jaxb2-plugin</artifactId>
        <executions>
          <execution>
            <goals>
              <goal>generate</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
</build>

在我的对象上，我有 getSource() 和 getVersion() 方法，但没有 getValue() 或类似的方法。我从根本上错过了什么吗？尝试以这种方式访问​​内部元素数据不正确吗？

编辑:包含生成的 Java 代码

Answer 1

payload 元素的架构定义应如下所示，以获取您正在查找的 JAXB 类。您将需要修复从 XML 文档生成 XML 架构的方式。

<element name="payload">
    <complexType>
        <simpleContent>
            <extension base="string">
                <xsd:attribute name="source" type="xsd:string" />
                <xsd:attribute name="version" type="xsd:string" />
            </extension>
        </simpleContent>
    </complexType>
</element>
