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。
