Usage

From source file:org.springframework.http.converter.FormHttpMessageConverterTests.java

@Test
public void writeMultipartOrder() throws Exception {
    MyBean myBean = new MyBean();
    myBean.setString("foo");

    MultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
    parts.add("part1", myBean);

    HttpHeaders entityHeaders = new HttpHeaders();
    entityHeaders.setContentType(MediaType.TEXT_XML);
    HttpEntity<MyBean> entity = new HttpEntity<>(myBean, entityHeaders);
    parts.add("part2", entity);

    MockHttpOutputMessage outputMessage = new MockHttpOutputMessage();
    this.converter.setMultipartCharset(StandardCharsets.UTF_8);
    this.converter.write(parts, new MediaType("multipart", "form-data", StandardCharsets.UTF_8), outputMessage);

    final MediaType contentType = outputMessage.getHeaders().getContentType();
    assertNotNull("No boundary found", contentType.getParameter("boundary"));

    // see if Commons FileUpload can read what we wrote
    FileItemFactory fileItemFactory = new DiskFileItemFactory();
    FileUpload fileUpload = new FileUpload(fileItemFactory);
    RequestContext requestContext = new MockHttpOutputMessageRequestContext(outputMessage);
    List<FileItem> items = fileUpload.parseRequest(requestContext);
    assertEquals(2, items.size());//from   ww w . ja  v a2  s .c o m

    FileItem item = items.get(0);
    assertTrue(item.isFormField());
    assertEquals("part1", item.getFieldName());
    assertEquals("{\"string\":\"foo\"}", item.getString());

    item = items.get(1);
    assertTrue(item.isFormField());
    assertEquals("part2", item.getFieldName());

    // With developer builds we get: <MyBean><string>foo</string></MyBean>
    // But on CI server we get: <MyBean xmlns=""><string>foo</string></MyBean>
    // So... we make a compromise:
    assertThat(item.getString(), allOf(startsWith("<MyBean"), endsWith("><string>foo</string></MyBean>")));
