我正在学习Freemarker框架,我有这个问题。 我可以将自定义对象传递给模板文件吗?我看到这些帖子说他们做了我说的话,但它对我不起作用。

Passing a List of Objects to Freemarker and then Looping

我知道春天可以帮助我,但我想尝试没有它。

我的代码是:

的Servlet

public class servletTest extends HttpServlet {

/**
 * @see Servlet#init(ServletConfig)
 */
public void init(ServletConfig servConfig) throws ServletException {
    // TODO Auto-generated method stub

    try {
        cfg = config.getConfig();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}


/**
 * Questa chiamata permette di chiamare il file di configurazione per il
 * template
 */
private Configuration             cfg;




protected void doGet(HttpServletRequest request,
                     HttpServletResponse response) throws ServletException, IOException {


    PrintWriter out = response.getWriter();



     SimpleHash root = new SimpleHash();
     // expose a "simple" java objects:
     root.put("theString", "wombat");
     // expose an "arbitrary" java objects:
     root.put("theObject", new banquet( "Thinking In Java") );


    /* Get the template */
    Template template = cfg.getTemplate("banquetsList.ftl");

    Writer out_template = new StringWriter();

    try {

        template.process( root, out_template );

    } catch (TemplateException e) {
        e.printStackTrace();
    }

    out.write( out_template.toString() );



}



}

配置文件:

   private static void build_config() throws IOException{


    cfg = new Configuration();

    cfg.setServletContextForTemplateLoading( R.context.get_servletContext(), R.path.get_TEMPLATE() );

    DefaultObjectWrapper ObjectWrapper = new DefaultObjectWrapper();

    cfg.setObjectWrapper( ObjectWrapper.DEFAULT_WRAPPER );
    cfg.setDefaultEncoding("UTF-8");
    cfg.setTemplateExceptionHandler(TemplateExceptionHandler.HTML_DEBUG_HANDLER);
    cfg.setIncompatibleImprovements(new Version(2, 3, 20));




}

宴会班:

class banquet{

banquet( /*int code,*/ String title){
    //this.code = code;
    this.title = title;
}
public String title;
//public int code;

 }

模板文件:

<html>

<body>

    <h1>
        lista di banchetti
    </h1>



    <div>

    </div>

    <div>


               ${theObject.name}
    </div>



</body>

我错了或Freemarker有错误?是的我是菜鸟,但这个问题让我开玩笑......

事先感谢所有人:)

我找到了解决方案! 我已经将PUBLIC添加到宴会bean中,我感谢所有人使用setter和getter方法:)
