Spring MVC. How do I process JSP to string with model as an argument

Question

Whats JSPs equivalent of FreeMarker class FreeMarkerTemplateUtils.processTemplateIntoString which accepts two arguments (Template template, Object model).

Using FreeMarker, the code looks like:

public String getReport(ModelMap model) throws Exception {
    model.addAttribute("name",  "tim");
    String template = "testing.ftl";
    String htmlStr = FreeMarkerTemplateUtils.processTemplateIntoString(
            freemarkerConfig.getConfiguration().getTemplate(template),
            model);
    // ...
}

How can I achieve above using JSP?

Using JSPs you have two options:

1) Fill the model and return the logical name of the view

2) Create and return a ModelAndView object

Controller - Option 1

public String getReport(Model model) throws Exception {

    model.addAttribute("name",  "tim");

    //you should have testing.jsp
    return "testing";
}

Controller - Option 2

public ModelAndView getReport(HttpServletRequest arg0,
        HttpServletResponse arg1) throws Exception {

    ModelAndView modelAndView = new ModelAndView("testing");
    modelAndView.addObject("name", "tim");

    return modelAndView;
}

In both ways, the view (JSP page) can access the model data as shown bellow.

testing.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
    <p>${name}</p>
</body>
</html>

Hi. Main reason for string conversion is to generate a pdf document from it and not displaying the page it self. – Kelvin Muia Mar 09 '16 at 13:59
Now I understood your requirement. I think that is impossible to do with JSP templates. – nnunes10 Mar 09 '16 at 14:44
