检索并分配 jcr:mixin 在 magnolia 中键入多值属性

Question

当我尝试在 Magnolia 中获取多值属性时，我收到错误，因为我将其分配给字符串类型。如何正确读取单值和多值属性(因为两者都存在(？

javax.jcr.ValueFormatException： property/wcmstest/de/search/jcr：mixinTypes 是一个多值属性，所以它是 值只能作为数组检索 at org.apache.jackrabbit.core.PropertyImpl.internalGetValue(PropertyImpl.java：483( at org.apache.jackrabbit.core.PropertyImpl.getValue(PropertyImpl.java：510( at org.apache.jackrabbit.core.PropertyImpl.getString(PropertyImpl.java：520( at info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString(DelegatePropertyWrapper.java：162( at info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString(DelegatePropertyWrapper.java：162( at info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString(DelegatePropertyWrapper.java：162( at info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString(DelegatePropertyWrapper.java：162( at info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString(DelegatePropertyWrapper.java：162( at ch.uzh.module.versioning.CreateNestedMap.nestedMap(CreateNestedMap.java：32( at ch.uzh.module.versioning.ContextLoggerCommand.execute(ContextLoggerCommand.java：78( at info.magnolia.command.MgnlCommand.executeSynchronized(MgnlCommand.java：80( at info.magnolia.command.MgnlCommand.execute(MgnlCommand.java：69( at info.magnolia.command.chain.ChainBase.execute(ChainBase.java：101( at info.magnolia.command.DelegateCommand.execute(DelegateCommand.java：66( :

这是我正在使用的代码：

HashMap<String, Object> map = new LinkedHashMap<>();
PropertyIterator pi;
try {
pi = node.getProperties();
//Get properties for the root node
while(pi.hasNext())
{
Property p = pi.nextProperty();
String name = p.getName();
String val = p.getString();
map.put(name,val);
}//end of while for properties of root node
} catch (RepositoryException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

感谢@reporter和一些反复试验。这是一个working solution.

HashMap<String, Object> map = new LinkedHashMap<>();
PropertyIterator pi;
try {
pi = node.getProperties();
//Get properties for the root node
while(pi.hasNext())
{
Property p = pi.nextProperty();
String name = p.getName();
String val;
//determine if property is multi-value
if (p.isMultiple()) {
//multi-value property           
val=p.getValues().toString();
} else {
//single-value property
val = p.getValue().getString();
}
map.put(name,val);
}//end of while for properties of root node
} catch (RepositoryException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
