ModelAndView转发

Question

Spring MVC ModelAndView转发无效。以下代码不会将请求转发给Name.jsp。非常感谢你的帮助。

package main.java.com.mkyong.common.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class indexController {@RequestMapping(value= {"/index"})    
public ModelAndView forward() {
    ModelAndView model = new ModelAndView( "forward:/pages/Name.jsp");
    model.addObject("msg","Forward Handled");
    return model;

}}

Answer 1

你需要将返回类型替换为String并返回＆＃34; forward：/ some / where /＆＃34;所以，你请求处理程序看起来像这样：

package main.java.com.mkyong.common.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class indexController {@RequestMapping(value= {"/index"})    
public String forward() {
    model.addObject("msg","Forward Handled");
    return "forward:/some/where/to/go";

}}

Answer 2

尝试使用此

@RequestMapping(value = "/index", method = RequestMethod.GET)
public ModelAndView forward(Model model) {

    model.addAttribute("msg","Forward Handled");

    return new ModelAndView("/pages/Name.jsp");
}

Answer 3

请注意，根据您的用例，可接受的答案可能不正确。

要使用ModelAndView转发（有时您不能返回字符串）：

return new ModelAndView("forward:/error");
