Hi
I'm having problems with reproducing this issue. I thought I'd do a quick
test this evening but I proved to be wrong :-)
First I had to modify a bit the classes for a basic test to even start
working, to bypass JAXB complaints.
So here's what I have now.
testIt() results in
{"ns1.definition": {"@repeating":"false","@index":"0","@name":"Credit Line
Increase Data",
"ns1.structure":{"@repeating":"false","@index":"2","@name":"CreditLineIncConversation",
"ns1.symbolic":[
{"@index":"0","@name":"ReasonForIncrease"},
{"@index":"4","@name":"TermConds"}
]
}
}
}
which is a simpler but a similar structure instance.
@Test
public void testIt() throws Exception {
JSONProvider p = new JSONProvider();
//p.setSerializeAsArray(true);
//p.setArrayKeys(Collections.singletonList("structure"));
DataDefinition dd = new DataDefinition();
dd.setName("Credit Line Increase Data");
List<Field> fields = new ArrayList<Field>();
Structure s = new Structure();
s.setIndex(2);
s.setName("CreditLineIncConversation");
List<Field> fields2 = new ArrayList<Field>();
SymbolicField sf1 = new SymbolicField();
sf1.setIndex(0);
fields2.add(sf1);
sf1.setName("ReasonForIncrease");
SymbolicField sf2 = new SymbolicField();
sf2.setIndex(4);
sf2.setName("TermConds");
fields2.add(sf2);
s.setFields(fields2);
fields.add(s);
dd.setFields(fields);
ByteArrayOutputStream os = new ByteArrayOutputStream();
p.writeTo(dd, (Class)DataDefinition.class, DataDefinition.class,
DataDefinition.class.getAnnotations(),
MediaType.APPLICATION_JSON_TYPE, new MetadataMap<String,
Object>(), os);
String str = os.toString();
System.out.println(str);
}
readIt() tries to read this data :
@Test
public void readIt() throws Exception {
String s =
"{\"ns1.definition\":{\"@repeating\":\"false\",\"@index\":\"0\",\"@name\":"
+ "\"Credit Line Increase
Data\",\"ns1.structure\":{\"@repeating\":\"false\",\"@index\":\"2\","
+
"\"@name\":\"CreditLineIncConversation\",\"ns1.symbolic\":[{\"@index\":\"0\",\"@name\":"
+
"\"ReasonForIncrease\"},{\"@index\":\"4\",\"@name\":\"TermConds\"}]}}}";
JSONProvider p = new JSONProvider();
Map<String, String> namespaceMap = new HashMap<String, String>();
namespaceMap.put("http://bla";, "ns1");
p.setNamespaceMap(namespaceMap);
byte[] bytes = s.getBytes();
Object object = p.readFrom((Class)DataDefinition.class,
DataDefinition.class,
DataDefinition.class.getAnnotations(),
null, null, new
ByteArrayInputStream(bytes));
DataDefinition dd = (DataDefinition)object;
Field struct = dd.getFieldsAsMap().get("CreditLineIncConversation");
}
but gets a ClassCastException at
DataDefinition dd = (DataDefinition)object;
because it is a Structure object.
and here're the slightly updated classes :
@XmlRootElement(name = "definition", namespace = "http://bla";)
public static class DataDefinition extends Structure {
}
@XmlRootElement(name = "definition", namespace = "http://bla";)
@XmlSeeAlso({DataDefinition.class, SymbolicField.class})
public static class Structure extends Field {
@XmlAttribute(required = false)
boolean repeating = false;
public boolean isRepeating() {
return repeating;
}
@XmlElements( { @XmlElement(name = "structure",
namespace="http://bla";, type = Structure.class),
@XmlElement(name = "numeric", namespace="http://bla";,
type = NumericField.class),
@XmlElement(name = "symbolic", namespace="http://bla";,
type = SymbolicField.class),
@XmlElement(name = "date", namespace="http://bla";, type
= DateField.class),
@XmlElement(name = "boolean", namespace="http://bla";,
type = BooleanField.class) })
private List<Field> fields;
// public List<Field> getFields() {
// return fields;
// }
public void setFields(List<Field> fields) {
this.fields = fields;
}
public Map<String, Field> getFieldsAsMap() {
Map<String, Field> fieldMap = new HashMap<String,
Field>();
for (Field field : fields) {
fieldMap.put(field.name, field);
}
return fieldMap;
}
}
@XmlSeeAlso({DataDefinition.class, Structure.class})
public static abstract class Field implements Serializable {
@XmlAttribute
String name;
// public String getName() {
// return name;
// }
public void setName(String name) {
this.name = name;
}
@XmlAttribute(required = false)
long index;
// public long getIndex() {
// return index;
// }
//
public void setIndex(long index) {
this.index = index;
}
}
@XmlRootElement(name = "symbolic", namespace = "http://bla";)
public static class SymbolicField extends Field {
}
public static class NumericField extends Field {
}
public static class DateField extends Field {
}
public static class BooleanField extends Field {
}
Please send me more info which can help me in reproducing it...
Cheers, Sergey
