Question

我既不使用ResponseBody也不使用RestController注释仍然，我的Spring Application返回的是String而不是jsp / html页面。

这是我的应用程序配置和控制器文件。我要去哪里错了？

Web配置文件：

package com.springimplant.mvc.config;

import java.io.IOException;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;  
import org.springframework.context.annotation.Configuration;

@Configuration  
@EnableWebMvc  
@ComponentScan(basePackages="com.springimplant.mvc.controllers")  
public class SimpleWebConfiguration implements WebMvcConfigurer {

    @Bean
    public ViewResolver internalResourceViewResolver() {
//      UrlBasedViewResolver bean = new UrlBasedViewResolver();
        InternalResourceViewResolver bean = new InternalResourceViewResolver();
        bean.setViewClass(JstlView.class);
        bean.setPrefix("/WEB-INF/views/");
        bean.setSuffix(".jsp");
        bean.setOrder(0);
        return bean;
    }

    @Bean
    public ViewResolver resourceBundleViewResolver() {
        ResourceBundleViewResolver bean = new ResourceBundleViewResolver();
        bean.setBasename("views");
        bean.setOrder(1);
        return bean;
    }

    @Bean
    public ViewResolver xmlViewResolver(){
        XmlViewResolver bean = new XmlViewResolver();
        bean.setLocation(new ClassPathResource("views.xml"));
        bean.setOrder(2);
        return bean;
    }

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.jsp("/WEB-INF/views/", ".jsp");
    }

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
//      registry.addViewController("/").setViewName("forward:/welcome");
    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }


}

HomeController：

package com.springimplant.mvc.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/")
public class HomeController {

    @RequestMapping(value="welcome",method=RequestMethod.GET)
    public ModelAndView welcome()
    {
        return new ModelAndView("welcome");
    }
}

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Welcome Home</title>
</head>
<body>
Welcome Home
</body>
</html>

所以我将这些页面标签放在我删除的jsp文件上，现在运行正常，但是为什么呢？在以前的项目中，我不必这样做。

Spring不断返回String作为Response而不是HTML
