XPath injection cannot handle expressions returning strings
-----------------------------------------------------------
Key: CAMEL-2122
URL: https://issues.apache.org/activemq/browse/CAMEL-2122
Project: Apache Camel
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Maciej Prochniak
Priority: Minor
trying to inject following:
public void insert(@XPath("concat('48','//node/msisdn/text())") String msisdn)
{ }
results in Can not convert #STRING to a NodeList! exception.
The reason is that XPathAnnotationExpressionFactory uses
XPathBuilder.xpath(xpath); -by default xpath is evaluated as nodeSet.
I think it would be nice to be able to define result type in annotation e.g.
@XPath(value = "concat('48','//node/msisdn/text())", resultType = String.class)
- the default would be NodeSet to be backward compatible
