检索并为jcr：mixinTypes分配木兰中的多值属性

Question

尝试在木兰中获取多值属性时出现错误，因为我将其分配给String类型。如何正确读取一个单值和多值属性（因为两者都存在）？

javax.jcr.ValueFormatException：属性/ wcmstest / de / search / jcr：mixinTypes是一个多值属性，因此它是值只能作为数组检索在org.apache.jackrabbit.core.PropertyImpl.internalGetValue（PropertyImpl.java:483）在org.apache.jackrabbit.core.PropertyImpl.getValue（PropertyImpl.java:510）在org.apache.jackrabbit.core.PropertyImpl.getString（PropertyImpl.java:520）在info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString（DelegatePropertyWrapper.java:162）在info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString（DelegatePropertyWrapper.java:162）在info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString（DelegatePropertyWrapper.java:162）在info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString（DelegatePropertyWrapper.java:162）在info.magnolia.jcr.wrapper.DelegatePropertyWrapper.getString（DelegatePropertyWrapper.java:162）在ch.uzh.module.versioning.CreateNestedMap.nestedMap（CreateNestedMap.java:32）在ch.uzh.module.versioning.ContextLoggerCommand.execute（ContextLoggerCommand.java:78）在info.magnolia.commands.MgnlCommand.executeSynchronized（MgnlCommand.java:80）在info.magnolia.commands.MgnlCommand.execute（MgnlCommand.java:69）在info.magnolia.commands.chain.ChainBase.execute（ChainBase.java:101）在info.magnolia.commands.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();
            }
