如何訪問角對象中的列表（通過Java Rest）

我使用Jhipster來生成我的代碼。如何訪問角對象中的列表（通過Java Rest）

我有一個類的日曆與事件列表。我想訪問我的角度控制器/視圖中的事件列表。我可以通過查詢Java Rest來訪問對象日曆。但calendar.events未定義，無法直接訪問列表。

如何在控制器中聲明事件列表？

的Java配件： Calendar.java

@OneToMany(mappedBy = "calendar", cascade = { CascadeType.ALL }, orphanRemoval = true) 
@JsonIgnore 
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) 
private Set<Event> events = new HashSet<>();

Event.java

@ManyToOne 
private Calendar calendar;

CalendarResource.java

@RequestMapping(value = "/calendars/{id}", 
    method = RequestMethod.GET, 
    produces = MediaType.APPLICATION_JSON_VALUE) 
@Timed 
@Transactional(propagation=Propagation.REQUIRED) 
public ResponseEntity<Calendar> getCalendar(@PathVariable Long id) { 
    log.debug("REST request to get Calendar : {}", id); 
    Calendar calendar = calendarRepository.findOne(id); 
    return Optional.ofNullable(calendar) 
     .map(result -> new ResponseEntity<>(
      result, 
      HttpStatus.OK)) 
     .orElse(new ResponseEntity<>(HttpStatus.NOT_FOUND)); 
} 

@RequestMapping(value = "/calendars", 
    method = RequestMethod.GET, 
    produces = MediaType.APPLICATION_JSON_VALUE) 
@Timed 
@Transactional(propagation=Propagation.REQUIRED) 
public ResponseEntity<List<Calendar>> getAllCalendars(Pageable pageable) 
    throws URISyntaxException { 
    log.debug("REST request to get a page of Calendars"); 
    Page<Calendar> page = calendarRepository.findAll(pageable); 
    HttpHeaders headers = PaginationUtil.generatePaginationHttpHeaders(page, "/api/calendars"); 
    return new ResponseEntity<>(page.getContent(), headers, HttpStatus.OK); 
}

角件 calendar.service.js

(function() { 
'use strict'; 
angular 
    .module('mandefaApp') 
    .factory('Calendar', Calendar); 

Calendar.$inject = ['$resource']; 

function Calendar ($resource) { 
    var resourceUrl = 'api/calendars/:id'; 

    return $resource(resourceUrl, {}, { 
     'query': { method: 'GET', isArray: true}, 
     'get': { 
      method: 'GET', 
      transformResponse: function (data) { 
       if (data) { 
        data = angular.fromJson(data); 
       } 
       return data; 
      } 
     }, 
     'update': { method:'PUT' } 
    }); 
}

}）（）;

calendar.controller.js

(function() { 
'use strict'; 

angular 
    .module('mandefaApp') 
    .controller('CalendarController', CalendarController); 

CalendarController.$inject = ['$scope', '$state', 'Calendar', 'CalendarSearch', 'ParseLinks', 'AlertService', 'pagingParams', 'paginationConstants']; 

function CalendarController ($scope, $state, Calendar, CalendarSearch, ParseLinks, AlertService, pagingParams, paginationConstants) { 
    var vm = this; 

    vm.loadPage = loadPage; 
    vm.predicate = pagingParams.predicate; 
    vm.reverse = pagingParams.ascending; 
    vm.transition = transition; 
    vm.itemsPerPage = paginationConstants.itemsPerPage; 
    vm.clear = clear; 
    vm.search = search; 
    vm.loadAll = loadAll; 
    vm.searchQuery = pagingParams.search; 
    vm.currentSearch = pagingParams.search; 

    loadAll(); 

    function loadAll() { 
     if (pagingParams.search) { 
      CalendarSearch.query({ 
       query: pagingParams.search, 
       page: pagingParams.page - 1, 
       size: vm.itemsPerPage, 
       sort: sort() 
      }, onSuccess, onError); 
     } else { 
      Calendar.query({ 
       page: pagingParams.page - 1, 
       size: vm.itemsPerPage, 
       sort: sort() 
      }, onSuccess, onError); 
     } 
     function sort() { 
      var result = [vm.predicate + ',' + (vm.reverse ? 'asc' : 'desc')]; 
      if (vm.predicate !== 'id') { 
       result.push('id'); 
      } 
      return result; 
     } 
     function onSuccess(data, headers) { 
      vm.links = ParseLinks.parse(headers('link')); 
      vm.totalItems = headers('X-Total-Count'); 
      vm.queryCount = vm.totalItems; 
      vm.calendars = data; 
      vm.page = pagingParams.page; 
     } 
     function onError(error) { 
      AlertService.error(error.data.message); 
     } 
    } 

    function loadPage (page) { 
     vm.page = page; 
     vm.transition(); 
    } 

    function transition() { 
     $state.transitionTo($state.$current, { 
      page: vm.page, 
      sort: vm.predicate + ',' + (vm.reverse ? 'asc' : 'desc'), 
      search: vm.currentSearch 
     }); 
    } 

    function search (searchQuery) { 
     if (!searchQuery){ 
      return vm.clear(); 
     } 
     vm.links = null; 
     vm.page = 1; 
     vm.predicate = '_score'; 
     vm.reverse = false; 
     vm.currentSearch = searchQuery; 
     vm.transition(); 
    } 

    function clear() { 
     vm.links = null; 
     vm.page = 1; 
     vm.predicate = 'id'; 
     vm.reverse = true; 
     vm.currentSearch = null; 
     vm.transition(); 
    } 
}

}）（）;

HTML代碼：

<div class="table-responsive"> 
    <table class="jh-table table table-striped"> 
     <thead> 
      <tr jh-sort="vm.predicate" ascending="vm.reverse" callback="vm.transition()"> 
       <th jh-sort-by="id"><span translate="global.field.id">ID</span> <span class="glyphicon glyphicon-sort"></span></th> 
       <th jh-sort-by="title"><span translate="mandefaApp.calendar.title">Title</span> <span class="glyphicon glyphicon-sort"></span></th> 
       <th jh-sort-by="title">Event Size <span class="glyphicon glyphicon-sort"></span></th> 
      </tr> 
     </thead> 
     <tbody> 
      <tr ng-repeat="calendar in vm.calendars track by calendar.id"> 
       <td><a ui-sref="calendar-detail({id:calendar.id})">{{calendar.id}}</a></td> 
       <td>{{calendar.title}}</td> 
       <td>{{calendar.events.lenght}}</td> <!-- How can access to events in calendar object ? --> 
      </tr> 
     </tbody> 
    </table> 
</div>
