FreeMarker Not Able Display Chinese Character

问题:

First time use FreeMarker on JAVA project and stack on configure the chinese character.

I tried a lot of examples to fix the code like below, but it still not able to make it.

// Free-marker configuration object              
Configuration conf = new Configuration();            
conf.setTemplateLoader(new ClassTemplateLoader(getClass(), "/"));   
conf.setLocale(Locale.CHINA);
conf.setDefaultEncoding("UTF-8");

// Load template from source folder              
Template template = conf.getTemplate(templatePath);                                 
template.setEncoding("UTF-8");

// Get Free-Marker output value              
Writer output = new StringWriter();              
template.process(input, output);

// Map Email Full Content            
EmailNotification email = new EmailNotification();  
email.setSubject(subject);              
.......

Saw some example request to make changes on the freemarker.properties but i have no this file. I just import the .jar file and use it.

Kindly advise what should i do to make it display chinese character.

What exactly is the problem?

Anyway, cfg.setDefaultEncoding("UTF-8"); should be enough, assuming your template files are indeed in UTF-8. But, another place where you have to ensure proper encoding is when you convert the the template output back to "binary" from UNICODE text. So FreeMarker sends its output into a Writer, so everything is UNICODE so far, but then you will have an OutputStreamWriter or something like that, and that has to use charset (UTF-8 probably) that can encode Chinese characters.

You need to change your file encoding of your .ftl template files by saving over them in your IDE or notepad, and changing the encoding in the save dialog. There should be an Encoding dropdown at the bottom of the save dialog.
