如何使用Spring的MockMultipartHttpServletRequest？得到“未找到多部分边界”

如何使用Spring的MockMultipartHttpServletRequest？得到“未找到多部分边界”

您需要设置边界。

这里对边界是什么有很好的解释http://codingdict.com/questions/144876

要解决您的问题，请尝试以下代码。

    import java.io.IOException;    import java.nio.file.Files;    import java.nio.file.Path;    import java.nio.file.Paths;    import org.apache.commons.lang.ArrayUtils;    import org.springframework.mock.web.MockHttpServletResponse;    import org.springframework.mock.web.MockMultipartFile;    import org.springframework.mock.web.MockMultipartHttpServletRequest;public class FileUploadTest {    public void testDoPost() throws IOException { Path path = Paths.get("c:\temp\test.zip"); byte[] data = Files.readAllBytes(path); MockMultipartFile file = new MockMultipartFile("test.zip", "test.zip",         "application/zip", data); MockMultipartHttpServletRequest mockRequest = new MockMultipartHttpServletRequest(); String boundary = "q1w2e3r4t5y6u7i8o9"; mockRequest.setContentType("multipart/form-data; boundary="+boundary); mockRequest.setContent(createFileContent(data,boundary,"application/zip","test.zip")); mockRequest.addFile(file); mockRequest.setMethod("POST"); mockRequest.setParameter("variant", "php"); mockRequest.setParameter("os", "mac"); mockRequest.setParameter("version", "3.4"); MockHttpServletResponse response = new MockHttpServletResponse(); new FileUpload().doPost(mockRequest, response);        }        public byte[] createFileContent(byte[] data, String boundary, String contentType, String fileName){ String start = "--" + boundary + "rn Content-Disposition: form-data; name="file"; filename=""+fileName+""rn"          + "Content-type: "+contentType+"rnrn";; String end = "rn--" + boundary + "--"; // correction suggested @butfly  return ArrayUtils.addAll(start.getBytes(),ArrayUtils.addAll(data,end.getBytes()));        }}
