ModelAndView向前

Question

spring前进不起作用。下面的代码没有将请求转发给Name.jsp。你的帮助非常感谢。

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

试着用这个

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

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

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

Answer 2

您需要将返回类型替换为String并返回"forward:/some/where/“，因此，请求处理程序将如下所示：

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 3

请注意，所接受的答案可能不正确，这取决于您的用法。

若要使用ModelAndView转发(有时不能返回字符串)：

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