现在我正在使用SpringMVC编写一个web应用程序。但是当我试图调用JSP页面时，我看到的是404错误页面，而不是我的JSP。我已经尝试了许多变体来解决这个问题，但还没有任何结果。现在我不知道为什么它不起作用。请帮帮我

这是我的代码：

HomeController.java

package spring.controller;

import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HomeController {

    @RequestMapping(value = "/view", method = RequestMethod.GET)
    public ModelAndView view() {
        ModelAndView model = new ModelAndView("View");
        return model;
    }
}
MvcConfiguration.java

package spring.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@ComponentScan(basePackages="spring")
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{

    @Bean
    public ViewResolver getViewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/src/main/webapp/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }

}
View.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

看看这个更正是否对您有效。

试试这个-更改这个`resolver.setPrefix（“/src/main/webapp/WEB-INF/views/”）`对此-`resolver.setPrefix（“/WEB-INF/views/”）`尝试此操作-更改此`resolver.setPrefix（“/src/main/webapp/WEB-INF/views/”）`对此-`resolver.setPrefix（“/WEB-INF/views/”）`
