Examples with Part jakarta.servlet.http.Part used on opensource projects

Example 1 with Part

use of jakarta.servlet.http.Part in project spring-framework by spring-projects.

the class RequestPartServletServerHttpRequest method getBody.

@Override
public InputStream getBody() throws IOException {
    // Prefer Servlet Part resolution to cover file as well as parameter streams
    boolean servletParts = (this.multipartRequest instanceof StandardMultipartHttpServletRequest);
    if (servletParts) {
        Part part = retrieveServletPart();
        if (part != null) {
            return part.getInputStream();
        }
    }
    // Spring-style distinction between MultipartFile and String parameters
    MultipartFile file = this.multipartRequest.getFile(this.requestPartName);
    if (file != null) {
        return file.getInputStream();
    }
    String paramValue = this.multipartRequest.getParameter(this.requestPartName);
    if (paramValue != null) {
        return new ByteArrayInputStream(paramValue.getBytes(determineCharset()));
    }
    // Fallback: Servlet Part resolution even if not indicated
    if (!servletParts) {
        Part part = retrieveServletPart();
        if (part != null) {
            return part.getInputStream();
