Specific use

// Set up the data 
Map dataMap = new HashMap<>();
dataMap.put("transId","abc");
// Set version number 
Version version = new Version("2.3.28");
Configuration configuration = new Configuration(version);  
configuration.setDefaultEncoding("utf-8");  
// Template file path 
configuration.setDirectoryForTemplateLoading(new File("D:\freemarker.xml"));

Template template = configuration.getTemplate("freemarker.xml");  
ByteArrayOutputStream out = new ByteArrayOutputStream();
Writer w = new OutputStreamWriter(out, "utf-8");
 // Write data to the template 
template.process(dataMap, w);
w.close(); 
byte[] bytes = out.toByteArray();
out.close();
MultipartFile file = new MockMultipartFile(ContentType.APPLICATION_OCTET_STREAM.toString(), bytes);// Get the final template
