这是一个由之前的代码片段组合在一起的源程序文件。
千万不要忘了将 freemarker.jar
放到 CLASSPATH 中。
import freemarker.template.*;
import java.util.*;
import java.io.*;
public class Test {
public static void main(String[] args) throws Exception {
/* ------------------------------------------------------------------------ */
/* You should do this ONLY ONCE in the whole application life-cycle: */
/* Create and adjust the configuration singleton */
Configuration cfg = new Configuration(Configuration.VERSION_2_3_22);
cfg.setDirectoryForTemplateLoading(new File("/where/you/store/templates"));
cfg.setDefaultEncoding("UTF-8");
cfg.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW);
/* ------------------------------------------------------------------------ */
/* You usually do these for MULTIPLE TIMES in the application life-cycle: */
/* Create a data-model */
Map root = new HashMap();
root.put("user", "Big Joe");
Map latest = new HashMap();
root.put("latestProduct", latest);
latest.put("url", "products/greenmouse.html");
latest.put("name", "green mouse");
/* Get the template (uses cache internally) */
Template temp = cfg.getTemplate("test.ftl");
/* Merge data-model with template */
Writer out = new OutputStreamWriter(System.out);
temp.process(root, out);
// Note: Depending on what `out` is, you may need to call `out.close()`.
// This is usually the case for file output, but not for servlet output.
}
}
Note:
为了简单起见,这里压制了异常(在方法签名中声明了异常,译者注), 而在正式运行的产品中不要这样做。
