模拟MVC意外结果

Question

我正在测试这个控制器：

 package hello;

import java.time.LocalTime;
import java.util.ArrayList;
import java.util.Collection;
import java.util.HashMap;

import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

import org.json.JSONObject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.http.MediaType;

@RestController
public class OfficeRestController {

    @Autowired
    private OfficeRepository officeRepository;
    private HashMap<String, String> readingProblems = new HashMap<>();

    @RequestMapping(value = "/office/{id}", method = RequestMethod.GET)
    ResponseEntity<Office> readOfficeDetails(@PathVariable long id) {
        HttpStatus status = HttpStatus.OK;      
        if (officeRepository.findOne(id) == null)
            status = HttpStatus.NOT_FOUND;

        return new ResponseEntity<Office>(officeRepository.findOne(id), status);
    }

    @RequestMapping(value = "/offices", method = RequestMethod.GET)
    ResponseEntity<Collection<Office>> allOffices() {
        HttpStatus status = HttpStatus.OK;
        Collection<Office> ans = this.officeRepository.findAll();
        if (ans.size() == 0)
            status = HttpStatus.NOT_FOUND;

        return new ResponseEntity<Collection<Office>>(
                this.officeRepository.findAll(), status);
    }

    @RequestMapping(value = "/openOffices", method = RequestMethod.GET)
    ResponseEntity<Collection<Office>> openOffices() {
        HttpStatus status = HttpStatus.OK;
        boolean found = false;
        Collection<Office> ans = new ArrayList<Office>();
        for (Office office : officeRepository.findAll()) {
            LocalTime curTime = LocalTime.now();
            LocalTime opening = office.getOpenFrom();
            LocalTime closing = office.getOpenUntil();
            if ((curTime.compareTo(opening) == 0 || curTime.compareTo(opening) == 1)
                    && (curTime.compareTo(closing) == 0 || curTime
                            .compareTo(closing) == -1)) {
                found = true;
                ans.add(office);
            }
        }
        if (!found) {
            status = HttpStatus.NOT_FOUND;
        }
        return new ResponseEntity<Collection<Office>>(ans, status);
    }

    @RequestMapping(value = "/offices", method = RequestMethod.POST, consumes = "application/json", produces = "application/json")
    public ResponseEntity<Office> add(@RequestBody Office offices) {
        HttpStatus status = HttpStatus.CREATED;
        Office office = createNewOffice(offices);
        if (Office.regProblems.size() > 0) {
            status = HttpStatus.UNPROCESSABLE_ENTITY;
        }
        officeRepository.save(office);
        return new ResponseEntity<Office>(office, status);
    }

    public Office createNewOffice(Office officeObject) {
        Office office = new Office();
        office.setName(officeObject.getName());
        office.setLocation(officeObject.getLocation());
        office.setOpenFrom(officeObject.getOpenFrom().toString());
        office.setOpenUntil(officeObject.getOpenUntil().toString());
        office.setTimeDifference(officeObject.getTimeDifference().toString());
        return office;
    }

}

通过这个测试：

 package test;

import org.junit.Assert;
import org.junit.Before;

@RunWith(SpringJUnit4ClassRunner.class)

@WebAppConfiguration
public class OfficeRestControllerTest {

    private MediaType contentType = new MediaType(
            MediaType.APPLICATION_JSON.getType(),
            MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("UTF8"));

    private MockMvc mockMvc;

    private OfficeRestController officeRestController = new OfficeRestController();

    private HttpMessageConverter mappingJackson2HttpMessageConverter;

    private Office account;

    @Autowired
    private OfficeRepository officeRepository;

    @Autowired
    private WebApplicationContext webApplicationContext;

    @Autowired
    void setConverters(HttpMessageConverter<?>[] converters) {

        this.mappingJackson2HttpMessageConverter = Arrays
                .asList(converters)
                .stream()
                .filter(hmc -> hmc instanceof MappingJackson2HttpMessageConverter)
                .findAny().get();

        Assert.assertNotNull("the JSON message converter must not be null",
                this.mappingJackson2HttpMessageConverter);
    }

    @Before
    public void setup() throws Exception {
        this.mockMvc = webAppContextSetup(webApplicationContext).build();
        this.officeRepository.deleteAllInBatch();
        Office office = new Office();
        office.setName("Baku");
        office.setLocation("Azerbaijan");
        office.setOpenFrom("00:00");
        office.setOpenUntil("23:00");
        office.setTimeDifference("3");
        this.officeRepository.save(office);
    }

    @Test
    public void officeNotFound() throws Exception {
        mockMvc.perform(get("/office/2")).andExpect(status().isNotFound())
                .andReturn();
    }

    @Test
    public void officeFound() throws Exception {
        mockMvc.perform(get("/office/1")).andExpect(status().isOk())
                .andExpect(content().contentType(contentType));

    }

    @Test
    public void seeOpenOffices() throws Exception {
        mockMvc.perform(get("/openOffices")).andExpect(status().isOk())
                .andExpect(content().contentType(contentType));

    }

    protected String json(Object o) throws IOException {
        MockHttpOutputMessage mockHttpOutputMessage = new MockHttpOutputMessage();
        this.mappingJackson2HttpMessageConverter.write(o,
                MediaType.APPLICATION_JSON, mockHttpOutputMessage);
        return mockHttpOutputMessage.getBodyAsString();
    }

}

结果是：

但是有id=1条目。为什么结果是错的？
