将结构应用于集合

Question

我在java中有一个对象列表。每个对象应根据其属性值对与其相关的类别进行排序，结果也应进行排序。排序应基于配置文件中类别的位置。 我用json数组文件来定义结构

[
 {"Risk assessment":["risk assessment","...","..."]},
 {"Emergency plan":["emergency plan","..."]},
 {"Emergency maps":["emergency map","..."]},
 {"Evacuation test":["emergency test","..."]},
]  

我想这样的操作很快就会在Java8中实现。 是否存在任何库来概括使用json文件来定义结构？

这是我的代码从json文件

应用结构

 public static List<DocumentCategory> applyStructureToList(List<GISDocument> documents,String jsonFile) throws IOException{
    categoryMap = readMap(documents,jsonFile);
    List<DocumentCategory> documentCategories = new ArrayList<DocumentCategory>();
    for(GISDocument gisDocument:documents ){            
        final String title = gisDocument.getTitle().toUpperCase();
        mapLoop:
        for(Map<String,List<String>> mapElement:categoryMap){
            for(String key : mapElement.keySet()){
                for(String value:mapElement.get(key)){
                    //document title must contain one of the values of the category defined in the jsonFile.
                    if(title.contains(value.toUpperCase())){
                        DocumentCategory dc = new DocumentCategory();
                        dc.setTitle(key);
                        // if a category already exists then add the current document to the items
                        // otherwise append the new category
                        if(documentCategories.contains(dc)){// the method contains compares title property
                            documentCategories.get(documentCategories.indexOf(dc)).getItems().add(gisDocument);
                        }else{
                            dc.getItems().add(gisDocument);
                            documentCategories.add(dc);
                        }                            
                        break mapLoop;
                    }
                }
            }
        }
    }
    Collections.sort(documentCategories);
    return documentCategories;
}
