我的架构有元素
<xs:element name="field">
<xs:complexType>
<xs:sequence>
<xs:element ref="type" minOccurs="1" maxOccurs="1"/>
<xs:choice>
<xs:sequence>
<xs:choice>
<xs:element ref="content"/>
<xs:sequence>
<xs:element ref="cmd"/>
<xs:element ref="legend"/>
</xs:sequence>
</xs:choice>
<xs:element ref="id" minOccurs="0"/>
</xs:sequence>
<xs:sequence>
<xs:element ref="name"/>
<xs:choice>
<xs:sequence>
<xs:element ref="value"/>
<xs:element ref="label"/>
<xs:element ref="optional"/>
</xs:sequence>
<xs:sequence>
<xs:element ref="optional"/>
<xs:choice>
<xs:sequence>
<xs:element ref="options"/>
<xs:element ref="id" minOccurs="0"/>
</xs:sequence>
<xs:sequence>
<xs:element ref="label"/>
<xs:element ref="options"/>
</xs:sequence>
</xs:choice>
</xs:sequence>
<xs:sequence>
<xs:element ref="label"/>
<xs:element ref="optional"/>
<xs:choice minOccurs="0">
<xs:element ref="boxes"/>
<xs:element ref="id"/>
<xs:element ref="options"/>
</xs:choice>
</xs:sequence>
</xs:choice>
</xs:sequence>
<xs:sequence>
<xs:element ref="id"/>
<xs:element ref="name"/>
<xs:element ref="label"/>
<xs:element ref="optional"/>
</xs:sequence>
</xs:choice>
</xs:sequence>
</xs:complexType>
</xs:element>
这会生成类结构
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
"content"
})
@XmlRootElement(name = "field")
public class Field {
@XmlElementRefs({
@XmlElementRef(name = "legend", type = Legend.class),
@XmlElementRef(name = "id", type = JAXBElement.class),
@XmlElementRef(name = "name", type = JAXBElement.class),
@XmlElementRef(name = "cmd", type = JAXBElement.class),
@XmlElementRef(name = "options", type = Options.class),
@XmlElementRef(name = "content", type = Content.class),
@XmlElementRef(name = "type", type = JAXBElement.class),
@XmlElementRef(name = "label", type = Label.class),
@XmlElementRef(name = "boxes", type = Boxes.class),
@XmlElementRef(name = "optional", type = JAXBElement.class),
@XmlElementRef(name = "value", type = JAXBElement.class)
})
protected List<Object> content;
/**

在类中，所有作为基本字段的字段都分配了type = JAXBElement.class（ex.-id但它在实际模式中声明为xsd：string）
我试图从对象生成json
由于它被分配给JAXBElement，因此无法正常生成
生成的字段响应
{ “的declaredType”： “java.lang.String中”， “名”： “类型”， “值”： “textarea的”， “范围”： “javax.xml.bind.JAXBElement $ GlobalScope”， “无”：假的，“globalScope”：true，“typeSubstituted”：false}
i am looking to get json response like {type:textarea}
请帮助
答案 0 :(得分：0)
我通过为下面的字段编写自定义序列化程序来解决这个问题
public class customeSerializer2扩展了JsonSerializer {
@Override
public void serialize(Field field, JsonGenerator jgen,
SerializerProvider provider) throws IOException,
JsonProcessingException {
jgen.writeStartObject();
JAXBElement jaxbElement;
for (Object object : field.getContent()) {
if (object.getClass().isAssignableFrom(JAXBElement.class)) {
jaxbElement = (JAXBElement) object;
// jgen.writeFieldName(jaxbElement.getName().toString());
jgen.writeStringField(jaxbElement.getName().toString(),
jaxbElement.getValue().toString());// teRawValue(jaxbElement.getValue().toString());
} else {
//jgen.writeStartObject();
jgen.writeObjectField(object.getClass().getSimpleName(),object);
//jgen.writeEndObject();
}
}
jgen.writeEndObject();
}
}
并使用像
这样的对象映射器进行注册SimpleModule module = new SimpleModule("customeSerializerModule",
new Version(1, 0, 0, null));
module.addSerializer(Field.class, new customeSerializer2());
mapper.registerModule(module);
