Spring Boot测试错误：java.lang.IllegalArgumentException：页面不能为空

Question

@RepositoryRestController
@RequestMapping("movies")
public class MovieController {

    private MovieService movieService;
    private PagedResourcesAssembler<Movie> pagedAssembler;
    private MovieResourceAssembler movieResourceAssembler;

    @Autowired
    public void setMovieService(MovieService movieService) {
        this.movieService = movieService;
    }

    @Autowired
    public void setPagedAssembler(PagedResourcesAssembler<Movie> pagedAssembler) {
        this.pagedAssembler = pagedAssembler;
    }

    @Autowired
    public void setMovieResourceAssembler(MovieResourceAssembler movieResourceAssembler) {
        this.movieResourceAssembler = movieResourceAssembler;
    }

    // Return all movies with pagination
    @GetMapping
    public ResponseEntity<?> getAllMovies(Pageable pageable) {
        Page<Movie> moviePage = this.movieService.getAllMovies(pageable);
        // Remove some unnecessary fields
        //this.movieService.removeUndesirableFieldsFromListing(moviePage);
        return ResponseEntity.ok(this.pagedAssembler.toResource(moviePage, this.movieResourceAssembler));
    }
 }

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class MovieControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private MovieService movieService;

    @Test
    public void getAllMovies_PageableGiven_ShouldReturnMoviesPage() throws Exception {
        List<Movie> movieList = new ArrayList<>();
        movieList.add(new Movie());
        movieList.add(new Movie());
        Page<Movie> moviePage = new PageImpl<>(movieList);
        given(this.movieService.getAllMovies(PageRequest.of(0,2)))
                .willReturn(moviePage);
        this.mockMvc.perform(get("http://localhost:8080/api/movies?page=1"))
                .andExpect(status().isOk());
    }
}

NestedServletException：请求处理失败；嵌套异常是java.lang.IllegalArgumentException：页面不能为空！

您可以使用Spring的mockMvc对象将其注入到测试类中：

 @Autowired
 private MockMvc mockMvc;

我刚刚使用mockmvc.perform方法创建了一个测试方法，发送一个页面请求：

我的控制器代码：

@GetMapping(produces=MediaType.APPLICATION_JSON_UTF8_VALUE)
public List<BaseResponse> listAllBase(
        @PageableDefault(size = 50, page = 2) Pageable pageable) {

    // logger.debug("paginación recibida :{}",pageable);
    List<BaseResponse> findAllBases = baseService.findAllBases();
    return findAllBases;

}

mockMvc.perform(get("/base/?size=2&page=0")).andExpect(status().isOk())
             .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))                        .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
             .andExpect(jsonPath("$", hasSize(2)))                       .andExpect(jsonPath("$", hasSize(2)))
             .andExpect(jsonPath("$[0].name", equalToIgnoringCase("margarita")))

测试类方法：

您可以在项目中使用它：）
