java - 如何使SlingHttpServletRequest.getParts()在JUnit Test中返回正确的值？

我在编写junit测试以将SlingHttpServletRequest.getParts（）的for循环条件传递给getParts（）方法时遇到一些困难。实现没有问题，我能够正确处理文件附件。但是，我无法在junit测试中这样做。

以下是我的实现：

@Model(adaptables = SlingHttpServletRequest.class)
public class Comment {

    //Variables declaration

    @Inject
    private CommentService service;

    @PostConstruct
    public void setup() {
        requestData = new JSONObject();


        for (String item : request.getRequestParameterMap().keySet()) {

            try {
                    requestData.put(item, request.getParameter(item));
                }
            } catch (Exception e) {
                Throw error message
            }
        }

        //Upload attachment to server
        try {
            for (Part part : request.getParts()) {      <= The JUnit test stopped at this line and throw the error below

        } catch (Exception e) {
            Throw error message
        }

我尝试使用SlingHttpServletRequestWrapper类重写getParts方法，但无济于事。

以下是我的junit测试：

public class CommentTest {

    public final AemContext context = new AemContext();
    private CommentService commentService = mock(CommentService.class);

    @InjectMocks
    private Comment comment;

    private static String PATH = "/content/testproject/en/page/sub-page";

    @Before
    public void setUp() throws Exception {
        context.addModelsForPackage("de.com.adsl.sightly.model");
        context.load().json("/components/textrte.json", PATH);
        context.currentPage(PATH);
    }

    @Test
    public void testSetup() throws IOException, ServletException {
        //before
        context.request().setParameterMap(getRequestCat1());
        context.registerService(CommentService.class, commentService);

        Resource resource = context.resourceResolver().getResource(PATH + "/jcr:content/root/responsivegrid/textrte");
        assertNotNull(resource);

        //when
        comment = new CustomRequest(context.request()).adaptTo(Comment.class);

        //then
        comment.setup();

    }

    private class CustomRequest extends SlingHttpServletRequestWrapper {

        public CustomRequest(SlingHttpServletRequest request) {
            super(request);
        }

        @Override
        public Collection<Part> getParts() {
            final String mockContent =
                    "------WebKitFormBoundarycTqA2AimXQHBAJbZ\n" +
                            "Content-Disposition: form-data; name=\"key\"\n" +
                            "\n" +
                            "myvalue1\n" +
                            "------WebKitFormBoundarycTqA2AimXQHBAJbZ";

            final List<Part> parts = MockPart.parseAll(mockContent);
            assertNotNull(parts);

            return parts;
        }
    };
}

以下是我遇到的错误消息：

我在网上查找了各种解决方案，例如在编写语句时编写了两个模型，但没有成功。如果您以前遇到以下问题，我将不胜感激任何形式的帮助或知识共享。谢谢！

最佳答案

从MockSlingServletResquest的源代码中，它总是抛出该异常，因为模拟类尚不支持该异常。

https://github.com/apache/sling-org-apache-sling-servlet-helpers/blob/71ef769e5564cf78e49d6679a3270ba8706ae406/src/main/java/org/apache/sling/servlethelpers/MockSlingHttpServletRequest.java#L953

也许您应该考虑编写servlet或其他方法。
