freeMarker在java应用程序中的应用
java中使用freemarker生成静态页面文件(支持多语言)：
FreeMarkerTest：
?import java.io.BufferedWriter;
?import java.io.File;
?import java.io.FileOutputStream;
?import java.io.OutputStreamWriter;
?import java.io.Writer;
?import java.util.HashMap;
?import java.util.Locale;
?
?import freemarker.template.Configuration;
?import freemarker.template.Template;
public class FreeMarkerTest {
??? public static void main(String[] args) {
??????? FreeMarkerTest test = new FreeMarkerTest();
???????? test.getFile();
???????? test.getFile(Locale.JAPAN);
??? }
???
???? public void getFile() {
???????? Configuration freemarkerCfg = new Configuration();
???????? freemarkerCfg.setClassForTemplateLoading(this.getClass(),"/");
???????? freemarkerCfg.setEncoding(Locale.getDefault(),"UTF-8");
???????? Template template;
??????? try {
???????????? template = freemarkerCfg.getTemplate("t.ftl");
???????????? template.setEncoding("UTF-8");
???????????? File htmlFile = new File("t.html");
??????????? Writer out = new BufferedWriter(new OutputStreamWriter(
??????????????????? new FileOutputStream(htmlFile), "UTF-8"));
???????????? HashMap propMap = new HashMap();
??????????? propMap.put("user", "hermit");
???????????? template.process(propMap, out);
??????????? out.flush();
???????? } catch (Exception e) {
???????????? e.printStackTrace();
???????? }
???? }
???
???? public void getFile(Locale loc) {
???????? Configuration freemarkerCfg = new Configuration();
???????? freemarkerCfg.setClassForTemplateLoading(this.getClass(),"/");
???????? freemarkerCfg.setEncoding(Locale.getDefault(),"UTF-8");
???????? Template template;
??????? try {
??????????? template = freemarkerCfg.getTemplate("t.ftl",loc);
??????????? template.setEncoding("UTF-8");
??????????? File htmlFile = new File("t_"+loc.getLanguage()+"_"+loc.getCountry()+".html");
??????????? Writer out = new BufferedWriter(new OutputStreamWriter(
??????????????????? new FileOutputStream(htmlFile), "UTF-8"));
??????????? HashMap propMap = new HashMap();
??????????? propMap.put("user", "hermit");
??????????? template.process(propMap, out);
???????????? out.flush();
???????? } catch (Exception e) {
???????????? e.printStackTrace();
???????? }
???? }

}

t.ftl
<html>
<head>
? <title>Welcome!</title>
? <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=utf-8">
</head>
<body>
? <h1>Welcome ${user}!</h1>
</body>
</html>?
?
t_zh_CN.ftl
<html>
<head>
? <title>欢迎!</title>
? <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=utf-8">
</head>
<body>
? <h1>你好 ${user}!</h1>
</body>
</html>??
freemarker支持多语言国际化，只要把模板名称安装资源文件的写法就可以了,也就是name_语言_国家地区.ftl
如果找不到对应的语言，就会用默认语言的模板。
顺便抱怨一下，freemarker对于空值的处理太霸道了，没有值你就写个空或者写KEY也可以啊，弄一堆出错信息在那。。。。。。。。。。。。。。
