com.sun.istack.SAXException2:class java.util.LinkedHashMap及其任何超类在此上下文中都不为人所知,java,json,xml,jaxb,moxy,Java,Json,Xml,Jaxb,Moxy,我正在发送一个POST请求，创建一个名为ContentInstance的资源 资源： ContentInstance // // This file was generated by the JavaTM Architecture for XML Binding(JAXB) Reference Implementation, v2.2.4-2 import java.math.BigInteger; import javax.xml.bind.annotation.XmlAccessType;

我正在发送一个POST请求，创建一个名为
ContentInstance
的资源

资源：

ContentInstance

//
// This file was generated by the JavaTM Architecture for XML Binding(JAXB) Reference Implementation, v2.2.4-2

import java.math.BigInteger;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlSchemaType;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "stateTag",
    "creator",

})
@XmlRootElement(name = "contentInstance")
public class ContentInstance
    extends AnnounceableSubordinateResource

    @XmlElement(required = true)
    protected Object content;

    /**
     * Getter setters         * 
     */
}
我通过使用JAXB将资源对象转换为JSON来发送资源对象：

客户端

     ContentInstance cont = new ContentInstance();
     cont.setContent("Sid");
     cont.setStateTag(BigInteger.ONE);
     cont.setContentSize(BigInteger.TEN);

     JAXBContext ctx = JAXBContextFactory.createContext(new Class[] {ContentInstance.class}, null);

            try
            {
                Marshaller marshaller = ctx.createMarshaller();
                marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
                marshaller.setProperty(MarshallerProperties.MEDIA_TYPE, "application/json");
                marshaller.setProperty(MarshallerProperties.JSON_INCLUDE_ROOT, false);

                StringWriter sw = new StringWriter();
                System.out.println("Object=" + object);
                marshaller.marshal(object, sw);
                String jsonContent = sw.toString();
            }
            catch (JAXBException e){

                System.out.println("--------JAXB EXCEPTION------------\n" );
                e.printStackTrace();
                LOGGER.error("JAXB marshalling error!", e);
            }

      try {

         HttpEntity entity = new ByteArrayEntity(jsonContent.getBytes("UTF-8"));
         ((HttpPost) httpUriRequest).setEntity(entity);
         System.out.println("ENTITY" + entity);

       } catch (UnsupportedEncodingException e) {
         e.printStackTrace();
       }
在职： 我以
对象
类型检索资源，并获得该资源的
LinkedHashMap
。我使用
ObjectMapper
将其转换为我的
ContentInstance
类型

休息服务：

    @POST
    @Consumes({"application/json"})
    @Produces({"application/json"})
        public String handlePostRequest(Object resource) {

        System.out.println("\nINSIDE HANDLE POST: CONTENT CLASS " + resource.getClass());
        System.out.println("\nINSIDE HANDLE POST: " + resource);

        ObjectMapper objectMapper = new ObjectMapper(); 
        ContentInstance container = objectMapper.convertValue(resource, ContentInstance.class);
        System.out.println("\n State Tag: " + container.getStateTag() + "\nContent SIZE" + container.getContentSize() + "\nContent " + container.getContent());
        return "Dummy Data";
        }
我的SOP打印：

INSIDE HANDLE POST: CONTENT CLASS class java.util.LinkedHashMap
INSIDE HANDLE POST: {stateTag=1, contentSize=10, content={type=string, value=Sid}}
State Tag: 1
Content SIZE10
Content {type=string, value=Sid}
因此，我的SOP是打印它最初得到一个
LinkedHashMap
，然后通过
ObjectMapper
转换后，它打印校正数据。但在请求验证中，我得到了异常

服务器日志：

INSIDE HANDLE POST: CONTENT CLASS class java.util.LinkedHashMap
INSIDE HANDLE POST: {stateTag=1, contentSize=10, content={type=string, value=Sid}}
WriteValueAsString {"stateTag":1,"contentSize":10,"content":{"type":"string","value":"Sid"}}
 inside processRequest

如果我了解您的环境设置，您正在使用Jackson JAXB框架封送和解封送数据对象。如果我错了，请纠正我

先单独尝试以下两个选项，然后再一起尝试：

  • 将handlePostRequest方法中输入参数的类型更改为字符串：
    • 公共字符串handlePostRequest（字符串资源）{

    请让我知道它是否运行和打印什么。我怀疑框架正在尝试将对象类型映射到LinkedHashMap，这是默认映射

  • 使用以下内容修改注释标记：

    @职位

    • 在我在客户机中使用jackson库将POJO转换为json而不是JAXB之后，这个问题得到了解决

    客户端代码现在：

     ContentInstance cont = new ContentInstance();
 cont.setContent("Sid");
 cont.setStateTag(BigInteger.ONE);
 cont.setContentSize(BigInteger.TEN);

 ObjectMapper om = new ObjectMapper();
 om.setPropertyNamingStrategy(new CustomNamingStrategy());

        try {
            System.out.print("OBJECT MAPPER:---> JSON STRING" + om.writerWithDefaultPrettyPrinter().writeValueAsString(cont));
            jsonContent = om.writerWithDefaultPrettyPrinter().writeValueAsString(cont);
        } catch (JsonGenerationException e) {
            e.printStackTrace();
        } catch (JsonMappingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    问题是我的POJO中的
    内容
    参数的类型为
    对象
    ，JAXB在转换为json后正在制作
    LinkedHashMap
    ，这在JAXB上下文中没有提供（因此出现错误）。 现在，使用
    ObjectMapper
    ，
    content
    被正确地转换为Json

    例： 先前使用JAXB的
    内容
    被转换为
    LinkedHashMap

    content: {"type":"String", "value":"Sid"}
    使用Jackson
    ObjectMapper
    ：

    {content:“Sid”}

    相关：您是否在请求验证或响应验证中收到错误？（我感到困惑，因为如果它是请求验证中的错误，它不应该击中您的售后服务方法）或者我遗漏了什么？我是在请求验证中得到的。实际上，请求在服务器上登陆后会得到验证。您介意添加完整的堆栈跟踪吗？通常，封送拆收器用于将对象转换为xml或json（解编器用于将json/xml转换为对象）。因此，我很想知道是谁和如何触发您的Validational。那么您是否尝试使用响应测试它。确定（而不是返回字符串）（如中所示）…我仍然怀疑封送员正在试图将您的字符串转换为JSON。您能帮我回答我的问题吗？我有同样的问题，但我没有序列化为JSON，而是尝试序列化为XML。谢谢！@Yaz:您也可以将jackson for XML与
    jackson dataformat XML jar
    一起使用，如果这对您的案例有效，问题是答：谢谢
