This article is to share with you about how to garbled ServletResponse download files. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Generally speaking, there are two ways to solve garbled code:

1. Encode the file name (including Chinese characters) into UTF-8

String downloadOrigalFile = "Test file garbled .xlsx"

String downloadFileName = java.net.URLEncoder.encode (downloadOrigalFile, "UTF-8")

Response.setHeader ("Content-Disposition", "filename=" + downloadFileName)

If there is a space in the file name, you need to replace the space with the space under% 20diem UTFmur8 + for space.

DownloadFileName = downloadFileName.replace ("+", "% 20")

2. Encode the file name as ISO-8859-1 (because the default encoding is ISO-8859-1)

String downloadOrigalFile = "Test file garbled .xlsx"

Final String LOCALE_ENCODING = "gb2312"

/ / LOCALE_ENCODING=gb2312 here: you can usually use the System.getProperties () of java to traverse and get

/ / generally, there are two values that may be related to this. Please refer to the actual situation.

/ / sun.jnu.encoding=GBK

/ / file.encoding=UTF-8

Final String DEFAULT_ENCODING = "ISO-8859-1"

String downloadFileName = new String (downloadOrigalFile.getBytes (LOCALE_ENCODING), DEFAULT_ENCODING)

If there is a space in the file name, you need to replace the space with% 20

DownloadFileName = downloadFileName.replace ("", "% 20")

/ / if the getBytes () here does not specify a code, there may be problems when crossing platforms. It is recommended to specify a code clearly.

Response.setHeader ("Content-Disposition", "filename=" + downloadFileName)

=

3. If you want to display Chinese in the browser address, you generally need to modify the default code URIEncoding= "UTF-8" of the web container.

(that is, download files directly by get)

For example, the tomcat container is added in the following location in TOMCAT_HOME/conf/server.xml

4. Special coding commonly used in URL

The + sign in + URL indicates space 2B.

Spaces in the space URL can be signed with a + sign or encoded with% 20

/ separate directories and subdirectories% 2F

? Separate the actual URL and parameter 3F

Specify special character 25

# indicates bookmark 23

Delimiter% 26 between parameters specified in & URL

= the value of the parameter specified in URL 3D
