Question

开始使用Spring MVC，当我进入我的页面时，它将welcome.jsp作为纯文本加载（只显示源代码），我知道有人问过这一百万次，但我查看过很多问题而没有找到我的解决方案，因为大多数人都使用XML而且我使用java ..我仍然没有足够的经验在两者之间切换。

conf.class：

public class conf extends WebMvcConfigurerAdapter {

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

    @Bean
    public InternalResourceViewResolver jspViewResolver() {
        InternalResourceViewResolver bean = new InternalResourceViewResolver();
        bean.setViewClass(JstlView.class);
        bean.setPrefix("/views/");
        bean.setSuffix(".jsp");
        return bean;
    }
}

ServletInitializer.class：

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(Demo4Application.class,conf.class);
    }
}

welCont.class（Controller）：

@Controller
@RequestMapping("/spring/")
public class welCont {

    @RequestMapping(method = RequestMethod.GET)
    public String wel(ModelMap model)
    {
        model.addAttribute("test","testme");
        return "welcome";
    }
}

welcome.jsp：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h2>${test}</h2>
</body>
</html>

我认为错误的是

@RequestMapping("/spring/")

通常“/ spring /”请求应该转到DispatcherServlet。春季靴子不确定。

试试这个。

    @Controller
    public class WelCont {

        @RequestMapping(value="/foldername_if_avaiable/welcome/", method=RequestMethod.GET )
        public ModelAndView wel(
            @RequestParam(value="id", required=false) String id,
            ModelMap model, 
            HttpSession session,
            HttpServletRequest req) throws Exception {

            model.addAttribute("test","testme");

            return new ModelAndView("/foldername_if_avaiable/welcome", model);
        }
    }
