java - 使用 Jackson XML 映射器将 Java 列表序列化为 XML

Question

您好，我需要使用 Jackson-dataformat XMLMapper 从 JAVA 创建 XML。 XML 应该是这样的

<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>

但我总是喜欢用额外的“ ”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>

我正在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);

有人能帮帮我吗？请问如何删除多余的标签。我曾尝试使用 @XmlElement 但它无济于事。 TIA!!

试试下面的代码

@JacksonXmlRootElement(localName = "customer") 
class Customer {

    @JacksonXmlProperty(localName = "id")
    private int id;
    @JacksonXmlProperty(localName = "name")
    private String  name;

    @JacksonXmlProperty(localName = "addresses")
    @JacksonXmlElementWrapper(useWrapping = false)
    private Address[] address;

    // you can add it on getter method instead of declaration.  
    @JacksonXmlElementWrapper(useWrapping = false)
    public Address[] getAddress(){ 
        return address;
   }

   //getters, setters, toString             
}

class Address {

    @JacksonXmlProperty(localName = "city")
    private String city;

    @JacksonXmlProperty(localName = "state")
    private String state;
    // getter/setter 
}
