freemarker 用template快速构造XML

freemarker 用template快速构造XML

 

1. 需要jar freemarker-2.3.8.jar

2. demo 如下：

import java.io.File;
import java.io.IOException;
import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;

import freemarker.core.Environment;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateExceptionHandler;


public class Test {
	/**
     * <一句话功能简述>
     * <功能详细描述>
     * @param map map
     * @param fileName fileName
     * @return 字符串流
     * @see [类、类#方法、类#成员]
     */
    @SuppressWarnings("unchecked")
    public static String buil(Map map, String fileName)
    {
        String url = Test.class.getResource("").getPath().replaceAll("%20", " ");
        String path = url;
        StringWriter out = new StringWriter();
        try
        {
            Configuration configuration = new Configuration();
            configuration.setDirectoryForTemplateLoading(new File(path));

            Template template = configuration.getTemplate(fileName);
            template.setTemplateExceptionHandler(TemplateExceptionHandler.IGNORE_HANDLER);
            template.setEncoding("UTF-8");
            template.setOutputEncoding("UTF-8");
            Environment env = template.createProcessingEnvironment(map, out);

            env.process();
            out.flush();
        }
        catch (Exception e)
        {

        }
        finally
        {
            try
            {
                out.close();
            }
            catch (IOException e)
            {
                e.printStackTrace();
            }
        }

        return out.toString();
    }
public static void main(String[]arrgs)
{
	Map<String,String> map= new HashMap<String,String>();
	map.put("id", "test123456");
	System.out.println(buil(map,"test.ftl"));
}
}

test.ftl

<xml id ="${id}">
</xml>
