Writing Map key/value pairs produces incorrect XML tags
-------------------------------------------------------
Key: BETWIXT-63
URL: https://issues.apache.org/jira/browse/BETWIXT-63
Project: Commons Betwixt
Issue Type: Bug
Environment: Windows XP, Java 1.6.0_04, Eclipse
Reporter: Pete Ford
Priority: Minor
Using download version 0.8.
A Map field within a Javabean produces XML containing Key and Value tags by
default (i.e. without a .betwixt file):
Java:
private Map<String, String> details = new TreeMap<String, String>();
Example XML output:
<Details>
<entry>
<Key>...</Key>
<Value>...</Value>
</entry>
</Details>
When reading the generated XML back into Betwixt to reconstruct the bean, the
map is not populated. It appears that when reading, Betwixt looks for the tags
<key> and <value> (uncapitalized). Filtering the XML to replace <Key> with
<key>, etc., before reading in fixes the problem. It would appear that Betwixt
should be generating "<key>" and "<value>" when writing (to match the case of
the enclosing "<entry>" tag). Possibly this is something to do with using
Capitalized names (see the code below - it sets up a CapitalizedNamesMapper for
element names).
The code that configures the writer in this case is:
StringWriter sw = new StringWriter();
BeanWriter writer = new BeanWriter(sw);
writer.getXMLIntrospector().getConfiguration()
.setAttributesForPrimitives(true);
writer.getXMLIntrospector().getConfiguration()
.setWrapCollectionsInElement(true);
writer.enablePrettyPrint();
writer.getBindingConfiguration().setMapIDs(false);
// set a custom name mapper for attributes
writer.getXMLIntrospector().getConfiguration()
.setAttributeNameMapper(new HyphenatedNameMapper());
// set a custom name mapper for elements
writer.getXMLIntrospector().getConfiguration()
.setElementNameMapper(new CapitalizeNameMapper());
