Java XML包装器JSON格式问题

我有这门课：

 class A {
      @XmlElement(name = "bees")
      @XmlElementWrapper(name="bee")
      public List<B> bees;
    }

我需要：

  {
  "bees": {
    "bee": { .. }, "bee": { .. }, ..
  }
}

有人能帮忙吗？

用这个；我遇到了你所描述的同样的问题。我们使用的解决方案是将Maven依赖项从Jackson更改为json库。我们将此网站用作：

如果使用maven，则向pom添加依赖项

<dependency>
        <groupId>net.sf.json-lib</groupId>
        <artifactId>json-lib</artifactId>
        <version>2.3</version>
        <type>jar</type>
        <classifier>jdk15</classifier>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-io</artifactId>
        <version>1.3.2</version>
        <type>jar</type>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>xom</groupId>
        <artifactId>xom</artifactId>
        <version>1.1</version>
    </dependency>
  </dependencies>

结果

{
  "@certified": "true",
  "@processed": "true",
  "timestamp": "232423423423",
  "authors": [  {
    "firstName": "Tim",
    "lastName": "Leary"
  }],
  "title": "Flashbacks",
  "shippingWeight": "1.4 pounds",
  "isbn": "978-0874778700"
}

而不是：

{
  "bees": {
    "bee": { .. }, 
    "bee": { .. }, 
    ..
  }
}

我建议如下：

{
   "bees" : [ 
       { .. }, 
       { .. },
       ..
   } ]
}

以下是如何使用MOXy根据映射生成此JSON：

import java.util.*;
import javax.xml.bind.*;
import javax.xml.transform.stream.StreamSource;
import org.eclipse.persistence.jaxb.JAXBContextProperties;
import org.eclipse.persistence.jaxb.MarshallerProperties;

public class Demo {

    public static void main(String[] args) throws Exception {
        Map<String, Object> properties = new HashMap<String, Object>();
        properties.put(JAXBContextProperties.JSON_INCLUDE_ROOT, false);
        properties.put(JAXBContextProperties.JSON_WRAPPER_AS_ARRAY_NAME, true);
        JAXBContext jc = JAXBContext.newInstance(new Class[] {A.class}, properties);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        StreamSource xml = new StreamSource("src/forum19560166/input.xml");
        A a = unmarshaller.unmarshal(xml, A.class).getValue();

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.setProperty(MarshallerProperties.MEDIA_TYPE, "application/json");
        marshaller.marshal(a, System.out);
    }

}

  </bees>
</a>

public class BeeDetails
{
    public string details { get; set; }

}

public class Bee
