示例1: readOptimizedFilter

import org.apache.olingo.odata2.api.uri.expression.FilterExpression; //导入依赖的package包/类
@Test
public void readOptimizedFilter() throws Exception {
  GetEntitySetUriInfo uriInfo = createMockedUriInfo("Rooms");
  Edm edm = EdmMock.createMockEdm();

  FilterExpression exp = UriParserImpl.parseFilter(edm, edm.getEntityType("RefScenario", "Room"), "Version gt 105");
  Mockito.when(uriInfo.getFilter()).thenReturn(exp);

  List<Room> results = createRooms(1, 10);
  ReadResult<Room> readResult = ReadResult.forResult(results).filterApplied().build();
  Mockito.when(mockedDataSource.readData(Mockito.any(EdmEntitySet.class), Mockito.any(ReadOptions.class)))
      .thenReturn((ReadResult)readResult);

  ODataResponse result = dataSourceProcessor.readEntitySet(uriInfo, "application/json");

  StringHelper.Stream resultStream = StringHelper.toStream(result.getEntityAsStream());
  List<LinkedTreeMap<?, ?>> parsedResults = JsonHelper.getResults(resultStream.asString());
  Assert.assertEquals(10, parsedResults.size());
  Assert.assertEquals("Room with id: 1", parsedResults.get(0).get("Name"));
