beetl模板入门例子

beetl初级用法

public class BeetlEngine {

    public static String render(String template,String varName,Object varObject){

    StringTemplateResourceLoader resourceLoader =new StringTemplateResourceLoader();

        Configuration cfg =null;

        try {

            cfg =Configuration.defaultConfiguration();

        }catch (IOException e) {

            //log error

        }

        GroupTemplate gt =new GroupTemplate(resourceLoader, cfg);

        Template t =gt.getTemplate(template);

        t.binding(varName, varObject);

        return t.render();;

    }

public static void main(String[] args) {

        //假设Member是一个对象，有telephone和userName两个字段

        Member member =new Member();

        member.setTelephone("188");

        member.setUserName("yes");

        String str =render("hello,${member.userName}, tel:${member.telephone}","member",member);

        System.out.println(str);// 输出hello,yes, tel:188

        //以下是map用法

        Map m =new HashMap<>();

        m.put("userName","test");

        m.put("telephone",133);

        String str2 =render("hello,${m.userName}, tel:${m.telephone}","m",m);

        System.out.println(str2);//  输出：hello,test, tel:133

    }

}
