Editor to share with you what to do when the ResponseEntity returned by SpringMVC is garbled. I hope you will get something after reading this article. Let's discuss it together.

Return ResponseEntity garbled problem

The foreground queries the relevant data from the data to the background, and the result is that the data returned by the background is garbled in Chinese, as shown in the following figure.

Reason

For the String type, if the encoding type is not clearly specified in the code, the transmitted data may not be encoded correctly in the background (my guess is that time is limited, and later I will follow the source code and look at the documentation to find out the real reason)

Solve

Change the String type to user-defined Pojo, such as User, or to more advanced data types such as List. Then serialize through @ ResponseBody to solve the Chinese garbled problem, as shown in the following figure.

ResponseEntity download file name garbled in Chinese

SpringBoot downloads files with garbled code in Chinese

The code is as follows:

Return ResponseEntity.ok () .header ("Content-disposition", "attachment;filename=" + fileName) .contentLength (file.length ()) .contentType (MediaType.parseMediaType ("application/octet-stream")) .body (resource); solution

Encode the file name:

FileName = new String (fileName.getBytes ("UTF-8"), "ISO-8859-1"); problem solving
