First of all, thank JSCUD to provide good articles. "
Use freemarker to generate an HTML static file (instance) "
In our project, FreeMarker generated a static file. But here I want to say the problem. Our projects are all UTF-8 encodings. I directly use the way to use the flying clouds. The files generated in UTF-8 encoding are garbled, while GBK is normal (later found because I used Chinese operating systems. GBK View Normal).
Of course, I changed the FREMARKER configuration to UTF-8, my template file is also UTF-8 encoding. Here is the original code
public
Void
SetTemplatePath (Resource TemplatePath) {
THIS
.TemplatePath
=
TemplatePath;
//
Set the parameters of FreeMarker
FreeMarkercfg
=
New
CONFIGURATION ();
Try
{FreeMarkercfg.SetDirectoryFortemplateLoading (
THIS
.TemplatePath.GetFile ()); FreeMarkercfg.SetObjectWrapper
New
DefaultObjectWrapper ()); FreeMarkercfg.SetDefaultencoding
"
UTF-8
"
}
Catch
IOEXCEPTION EX) {
Throw
New
SYSTEMEXCEPTION
"
No Directory Found, please check you config.
"
}}

The reason is the different construction methods of OutputStreamWriter
OutputStreamWriter
(
Outputstream
OUT Creates OutputStreamWriter encoded using the default character.
OutputStreamWriter
(
Outputstream
OUT,
String
CHARSETNAME Creates OutputStreamWriter using the specified character set. This is a Chinese JDK document description, just starting to use the default constructor, so use the system default encoding, GBK, so write UTF-8 content with GBK encoding when generating static files, so in UTF- 8 There is a problem with the browsing. There is also the same attention to this problem with the modification of the template file.
