Null ModelAndView가 DispatcherServlet으로 반환되었습니다.

Spring, Hibernate 및 Apache Tiles를 사용하여 웹 응용 프로그램을 실행하려고합니다. 코드에 오류가없는 것 같지만 방금 404 페이지를 얻고 있습니다.

모든 최대 절전 모드 물건을 추가하기 전에 나는 웹 앱을 시험해 보았다. 그러나 데이터베이스가없는 웹 애플리케이션은 무엇입니까?

나는 이미 이것에 시간을 보냈고 단지 문제를 발견 할 수 없다 ...

최신 정보

제어 장치:

package com.example.controller;

import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/")
public class BlogController {
    @RequestMapping("/index.html")
    public String posts(Map<String, Object> map) {
        return "posts";
    }
}

해결법

==============================
1.String 대신 ModelAndView를 보내보십시오. 또는

String 대신 ModelAndView를 보내보십시오. 또는

ModelandView 메서드에 매개 변수로 맵 객체를 보낼 수 있습니다 (이미 오버로드되어 있음)
```
@Controller 
@RequestMapping("/") 
public class BlogController {
    @RequestMapping("/index.html")
    public ModelAndView posts(Map<String, Object> map) {
      return new ModelAndView("/index.jsp", "status", status);
    } 
}
```
==============================
2.나는 그것을 해결했다.

나는 그것을 해결했다.

두 가지 컨텍스트가 있습니다 : 루트 (응용 프로그램 전체)와 서블릿 컨텍스트 필자는 루트 컨텍스트에서 viewResolver, tilesConfigurer, tx : annotation-driven 및 mvc : annotation-driven을 정의했습니다.

서블릿 컨텍스트로 이동하면 문제가 해결됩니다.

업데이트 됨 viewResolver, tilesConfigurer, tx : annotation-driven 및 mvc : applicationContext.xml의 주석 기반 정의를 contextConfigLocation (dispatcher-servlet.xml)으로 이동했습니다.
