freemarker模板技术

示例：

import freemarker.template.Configuration;
import freemarker.template.SimpleHash;
import freemarker.template.Template;
import freemarker.template.TemplateException;

public class Test ...{
    public static Log log = LogFactory.getLog(Test.class);

    public static void main(String[] args) ...{
try ...{
            /**//*
            定义中的文件内容　test.ftl
            ${title}
            ${author}
            ${content}
            */
            Configuration cfg = new Configuration();
            String tempDir="d:/test";//定义模板存放路径
            //根据所在地方定义路径String tempDir= URLDecoder.decode(this.getClass().getClassLoader().getResource("../").getPath(), "UTF-8");
            String tempName="test.ftl";//定义模板名
            String outputDir="d:/test";//定义模板输出路径
            String outputName="d:/test.txt";//定义模板输出文件名
            cfg.setDirectoryForTemplateLoading(new File(tempDir));
            Template temp = cfg.getTemplate(tempName, Locale.US, "UTF-8");
            SimpleHash map = new SimpleHash();
            map.put("title", "hello");
            map.put("author", "beauty9235");
            map.put("content", "hello,world!");
            //定义将结果打印出来
            StringWriter out = new StringWriter();
            temp.process(map, out);   
            log.debug(out.toString());
            //定义生成文件
            File output = new File(outputDir, outputName);
            Writer writer = new FileWriter(output);
            try ...{
                temp.process(map, writer);
            } catch (TemplateException e) ...{
                e.printStackTrace();
            }
            
        } catch (TemplateException t) ...{
           log.debug(t.getMessage());
        } catch (IOException i) ...{
            log.debug(i.getMessage());
        }
        }
