json - jaxb issue with xsd:choice and xsd:sequence -
i have schema has below element
<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> this generate class structure

i looking json response {type:textarea} please help
i solved problem writing custom serializer field below
public class customeserializer2 extends jsonserializer {
@override public void serialize(field field, jsongenerator jgen, serializerprovider provider) throws ioexception, jsonprocessingexception { jgen.writestartobject(); jaxbelement jaxbelement; (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(); } } and registering object mapper like
simplemodule module = new simplemodule("customeserializermodule", new version(1, 0, 0, null)); module.addserializer(field.class, new customeserializer2()); mapper.registermodule(module);
