提问by Sharmistha Sinha
Hi I need to create an XML from JAVA using Hymanson-dataformat XMLMapper. The XML should be like
嗨，我需要使用 Hymanson-dataformat XMLMapper 从 JAVA 创建一个 XML。XML 应该像
<Customer>
<id>1</id>
<name>Mighty Pulpo</name>
<addresses>
<city>austin</city>
<state>TX</state>
</addresses>
<addresses>
<city>Hong Kong</city>
<state>Hong Kong</state>
</addresses>
</Customer>
But I get it always like with an extra "< addresses> < /addresses>" tag.
但我总是喜欢使用额外的“<addresses> </addresses>”标签。
<Customer>
<id>1</id>
<name>Mighty Pulpo</name>
<addresses>
<addresses>
<city>austin</city>
<state>TX</state>
</addresses>
<addresses>
<city>Hong Kong</city>
<state>Hong Kong</state>
</addresses>
<addresses>
</Customer>
I am using below code to create XML
我使用下面的代码来创建 XML
JaxbAnnotationModule jaxbAnnotationModule = new JaxbAnnotationModule();
XmlMapper mapper = new XmlMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
mapper.registerModule(jaxbAnnotationModule);
mapper.registerModule(new GuavaModule());
String xml = mapper.writeValueAsString(customer);
System.out.println(xml);
Please can some one help me? How can I remove the extra tag please. I have tried to use @XmlElement but it does not help help. TIA!!

Try the below code
试试下面的代码
@HymansonXmlRootElement(localName = "customer")
class Customer {
@HymansonXmlProperty(localName = "id")
private int id;
@HymansonXmlProperty(localName = "name")
private String name;
@HymansonXmlProperty(localName = "addresses")
@HymansonXmlElementWrapper(useWrapping = false)
private Address[] address;
//getters, setters, toString
}
class Address {
@HymansonXmlProperty(localName = "city")
private String city;
@HymansonXmlProperty(localName = "state")
private String state;
// getter/setter
}

Just to add to ManojP's answer, if adding the @HymansonXmlElementWrapper(useWrapping = false)on the declaration of your variable doesn't work (which was the case for me), adding it to the getter method will do the trick.
只是为了添加到 ManojP 的答案中，如果@HymansonXmlElementWrapper(useWrapping = false)在变量的声明中添加不起作用（对我来说就是这种情况），将它添加到 getter 方法就行了。

This setting changes default wrapping behavior, if you don't want to deal with annotation everywhere in your code.
如果您不想在代码中处处处理注释，则此设置会更改默认包装行为。
XmlMapper mapper = new XmlMapper();
mapper.setDefaultUseWrapper(false);
