在 magnolia 中检索并分配 jcr:mixinTypes 多值属性

Question

当我尝试在 magnolia 中获取多值属性时出现错误，因为我将其分配给了字符串类型。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 is a multi-valued property, so it's values can only be retrieved as an array 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.commands.MgnlCommand.executeSynchronized(MgnlCommand.java:80) at info.magnolia.commands.MgnlCommand.execute(MgnlCommand.java:69) at info.magnolia.commands.chain.ChainBase.execute(ChainBase.java:101) at info.magnolia.commands.DelegateCommand.execute(DelegateCommand.java:66) :

这是我使用的代码：

 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。这里有一个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();
            }
