XStream : duplicate field exception
java, xml, xml-parsing, xstream
Solution
The answer is right there in the debug information
Duplicate field taskName
path : /soaConnect/staging/stage/taskName[2]
UPDATE:
Looking at this answer I think you are missing some annotations
@XStreamAlias("stage")
public class Stage {
private String name;
@XStreamImplicit(itemFieldName="taskName")
private List<String> tasks;
@XStreamImplicit(itemFieldName="iconName")
private List<String> icons;
}
Problem
``` <staging> <stage> <name>aaaa</name> <taskName>aa</taskName> <taskName>qwqwse</taskName> <taskName>qwe</taskName> <iconName>asdad</iconName> <iconName>dasd</iconName> </stage> <stage> <name>dasda</name> <taskName>asdak</taskName> <taskName>dasdk1</taskName> <taskName>dasdask2</taskName> <iconName>dasdn</iconName> <iconName>dasdcon</iconName> </stage> </staging> ``` And this is my java class : ``` @XStreamAlias("stage") public class Stage { private String name; private List<String> taskName; private List<String> iconName; } ``` I am using XStream 1.4.2 to convert that XML data to Java object. I have seen couple of SO posts but still it does not solve my problem. Its throwing following exception: ``` com.thoughtworks.xstream.converters.reflection.AbstractReflectionConverter$DuplicateFieldException: Duplicate field taskName ---- Debugging information ---- field : taskName class : com.thbs.soaconnect.model.configuration.Stage required-type : com.thbs.soaconnect.model.configuration.Stage converter-type : com.thoughtworks.xstream.converters.reflection.ReflectionConverter path : /soaConnect/staging/stage/taskName[2] line number : 28 class[1] : java.util.ArrayList converter-type[1] : com.thoughtworks.xstream.converters.collections.CollectionConverter class[2] : com.thbs.soaconnect.model.configuration.Configuration version : null ``` I tried the following way as suggested by many before : ``` xstream.addImplicitCollection(Stage.class,"taskName", String.class); xstream.addImplicitCollection(Stage.class,"iconName", String.class); ``` Though it does not throws any exception, but it can not read the value, each element has. Can you please help me.
