Question

我有覆盖主要负载lazydatamodel的问题。加载方法的错误点。我正在使用primefaces 5.0。在Jboss Developer Studio 7.1中工作

 private LazyDataModel<City> mdlCityList;
    @PostConstruct
        public void init() {
            try {
                this.mdlCityList = new LazyDataModel<City>() {
                    private static final long serialVersionUID = 1L;

                    @Override
                    public List<City> load(int first, int pageSize,
                            String sortField, SortOrder sortOrder,
                            Map<String, String> filters) {
                        mdlCityList.setRowCount(cityFacade.count(filters));
                        return cityFacade.getResultList(first, pageSize, sortField,
                                sortOrder, filters);
                    }
                };
                mdlCityList.setRowCount(cityFacade
                        .count(new HashMap<String, String>()));
            } catch (Exception e) {
                System.out.println("Exception in CityListProducer " + e);
            }
        }

正如您所看到的，我正在实施@Override，但它仍然指出：

方法load（int，int，String，SortOrder，Map）类型new LazyDataModel（）{}必须覆盖或实现超类型方法

Answer 1

现在PF 5中的覆盖方法应该是

public List<Car> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String,Object> filters)

代替

public List<Car> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String,String> filters)

在您的方法中

Map<String,Object>代替Map<String,String>

Primefaces lazydatamodel加载覆盖不起作用
