我的目标是xml到Pojo,Pojo到json。我已经使用jaxb将xml转换为pojo。现在我正在尝试使用杰克逊Jaxb将pojo转换为json。我在哪里得到以下json,它在json中生成JXBElement类文件,如下所示。
{
"name" : "{http://xxx.xx.xx.xx.xx.xx.xx}CompositeResponse",
"declaredType" : "xxx.xx.xx.xx.xx.xx.xxCompositeResponseType",
"scope" : "javax.xml.bind.JAXBElement$GlobalScope",
"value" : {
"CompositeIndividualResponse" : [ {
"ResponseMetadata" : {
"ResponseCode" : "HS000000",
"ResponseDescriptionText" : "Success"
}
} ]
},
"nil" : false,
"globalScope" : true,
"typeSubstituted" : false
}
如何删除名称,declaredType,scope,nil,globalScope,typeSubstituted ang以获得以下json
{
"CompositeResponse":
{
"CompositeIndividualResponse" : [ {
"ResponseMetadata" : {
"ResponseCode" : "HS000000",
"ResponseDescriptionText" : "Success"
}
} ]
}
}
我一直在看这个post,但这对我不起作用。
我为杰克逊混音尝试的以下代码。
public class Main {
public static interface JAXBElementMixinT {
@JsonValue
Object getValue();
}
public static void main(String[] args) throws XMLStreamException, IOException {
ObjectMapper mapper = new ObjectMapper();
AnnotationIntrospector introspector = new JaxbAnnotationIntrospector(mapper.getTypeFactory());
mapper.setAnnotationIntrospector(introspector );
mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
mapper.addMixIn(JAXBElement.class, JAXBElementMixinT.class);
String result = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(employee);
System.out.println(result);
}
}
我也尝试了以下代码,但是没有运气。
public abstract class JAXBElementMixIn {
@JsonIgnore abstract String getScope();
@JsonIgnore abstract boolean isNil();
@JsonIgnore abstract boolean isGlobalScope();
@JsonIgnore abstract boolean isTypeSubstituted();
@JsonIgnore abstract Class getDeclaredType();
}
任何人都可以帮助我哪里做错了以及该怎么做。

事实上,我本周刚刚遇到了这个问题,并通过删除
解决了该问题AnnotationIntrospector introspector = new JaxbAnnotationIntrospector(mapper.getTypeFactory());
mapper.setAnnotationIntrospector(introspector );
片。我还没有回过头来研究如何添加它,但是那让您剩下的代码可以为我正确地工作,而我再也看不到JAXBElement包装器了。

最后,我能够解决问题。根据@Ryan的回答,我不需要以下代码:
AnnotationIntrospector introspector = new JaxbAnnotationIntrospector(mapper.getTypeFactory());
mapper.setAnnotationIntrospector(introspector );
但是我必须添加JaxbAnnotationModule module = new JaxbAnnotationModule(); mapper.registerModule(module)
,否则杰克逊将为每个元素生成链接和元数据。完整的代码如下
public class Main {
public static interface JAXBElementMixinT {
@JsonValue
Object getValue();
}
public static void main(String[] args) throws XMLStreamException, IOException {
ObjectMapper mapper = new ObjectMapper();
JaxbAnnotationModule module = new JaxbAnnotationModule();
mapper.registerModule(module)
mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
mapper.addMixIn(JAXBElement.class, JAXBElementMixinT.class);
String result = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(employee);
System.out.println(result);
}
}
