问题解决
将XmlElementRef注释更改为@XmlElementRef(name=“Option”,type=Option.class,required=false)后,将@XmlRootElement(name=“Option”)添加到选项中。班
更新:
根据laune的建议,我添加了两个类(Options和Option),并修改了GuimopProperties类,如下所示
@XmlAccessorType(XmlAccessType.FIELD)
public class GuiMOProperties
{
@XmlElement(name="Grouping")
private boolean grouping;
@XmlElement(name="Type")
private String type;
@XmlElement(name="Regex")
private String regex;
@XmlElement(name="DisplayName")
private String displayName;
@XmlElement(name="Options")
private Options options;
@XmlElement(name="Mask")
private String mask;
@XmlElement(name="DefaultValue")
private String defaultValue;
}
但当我必须新建一个JAXBContext实例时,出现了一些异常,如下所示:
JAXBContext jaxbContext = JAXBContext.newInstance(GuiMOProperties.class);

我为JAXB解析定义了一个类,如下所示:
@XmlAccessorType(XmlAccessType.FIELD)
public class GuiMOProperties
{
@XmlElement(name="Grouping")
private boolean grouping;
@XmlElement(name="Type")
private String type;
@XmlElement(name="Regex")
private String regex;
@XmlElement(name="DisplayName")
private String displayName;
@XmlElement(name="Options")
@XmlJavaTypeAdapter(OptionsAdapter.class)
private GuiMOOption options;
@XmlElement(name="Mask")
private String mask;
@XmlElement(name="DefaultValue")
private String defaultValue;
}
我必须对xml字符串进行如下解析:
<VolumeUpKey>
<Type/>
<Regex/>
<DisplayName/>
<Options>testOptions</Options>
<Mask/>
<DefaultValue/>
</VolumeUpKey>
<SSID>
<Type/>
<Regex/>
<DisplayName/>
<Options>
<Option name="1" value="1"></Option>
<Option name="2" value="2"></Option>
<Option name="3" value="3"></Option>
<Option name="4" value="4"></Option>
</Options>
<Mask/>
<DefaultValue/>
</SSID>
在我的OptionAdapter的解组方法中。类中,第一个选项元素工作正常,有一个字符串“testOptions”输入。但是,第二个one Options元素没有。输入参数将是\n\t\t\t\t,但不是字符串
选择适配器。分类如下
public class OptionsAdapter extends XmlAdapter<String, GuiMOOption>
{
@Override
public GuiMOOption unmarshal(String v) throws Exception
{
try
{
System.out.println("unmarshal string : " + v);
} catch (Exception e)
{
// TODO: handle exception
}
return null;
}
@Override
public String marshal(GuiMOOption v) throws Exception
{
// TODO Auto-generated method stub
return null;
}
}
任何帮助都很感激。
混合内容并不十分简单,尽管JAXB可以在没有适配器的情况下处理它。
您可以将选项字段的类型定义为选项(而不是GUIMOOption):
@XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "Options", propOrder = { "content" }) public class Options { @XmlElementRef(name = "field", type = JAXBElement.class, required = false) @XmlMixed protected List content; public List getContent() { if (content == null) { content = new ArrayList(); } return this.content; } }
该列表将包含JAXBElement类型的元素
@XmlAccessorType(XmlAccessType.FIELD)
public class Option {
@XmlAttribute
protected String name;
@XmlAttribute
protected String value;
//...
}
您必须迭代该列表,以了解您使用的是第一个XML表单还是第二个XML表单。在第一种情况下,只有一个字符串。在第二种情况下,包装的选项对象之间可能存在空白字符串。
当我使用JAXB时,出现了一些问题。 我将实体转换为xml字符串,一切正常。 但当我将xml字符串转换回实体时,一些信息丢失了(它们都具有相同的类型)。 在实体中:
错误中的SOAP WSDL URL是Spring Boot应用程序中的另一个web服务。试图理解为什么这会出现在错误中。 UnmarshalException:意外元素(URI:“”,local:“message”)。需要的元素是<{http://soap_wsdl_url}jaxb_pojo_name>
问题内容: 想象以下情况:我们从某个外部工具收到一个xml文件。最近,在此xml中,节点名称中或它们的richcontent标记中可能有一些转义的字符,如以下示例所示(简化): 在使用JAXB解组文件后,那些逃脱的字符将不被转义。不幸的是,我需要他们保持原样,这意味着逃脱了。有什么方法可以避免在解组时将这些字符转义? 使用JAXB甚至有可能实现这一目标,还是我们甚至必须考虑更改为其他xml阅读器A
问题内容: 我有一个使用Jaxb进行XML <->转换的应用程序,并使用maven-jaxb2-plugin自动生成了类。 在我模式的某个深处,我可以输入“ ANY” xml。 更新:这更好地描述了我的架构。一些已知的XML包装了一个完全未知的部分(“ any”部分)。 这样(通过jaxb)映射到这样的内部类。 当我解组整个结构时,这没问题。“任何对象”将呈现到org.apache.xerces.
问题内容: 如何使用下面的代码解组XML字符串并将其映射到下面的JAXB对象? 问题答案: 要传递XML内容,您需要将内容包装在中,然后将其解组:
我必须在JAXB中将xml解析为字符串对象。但是如何为这个xml创建对象 Country.xml 为了解析这个xml,我创建了一个类来映射对象,它创建对象并在控制台中打印出来。却不知道自己做错了什么。 当我运行程序时,我会得到 com . sun . XML . internal . bind . v2 . runtime . illegalanotationexception:illegalan
