Question

在最后几天，我阅读了有关Spring MVC和DispatcherServlet的文章数量。为了更好地理解，我开始使用两个DispatcherServlet开发基于注释的MVC Web应用程序。用于html的dispatcherHtml和用于jsp请求的dispatcherJsp。我知道html文件是静态的，但只是为了练习。

ApplicationInit

public class ApplicationInit extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[0];
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[0];
    }

    @Override
    protected String[] getServletMappings() {
        return new String[0];
    }

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        servletContext.addListener(new ContextLoaderListener(rootContext));

        // dispatcherHtml
        AnnotationConfigWebApplicationContext webContextHtml = new AnnotationConfigWebApplicationContext();
        webContextHtml.setParent(rootContext);
        webContextHtml.register(HtmlConfig.class);
        ServletRegistration.Dynamic dispatcherHtml = servletContext.addServlet("dispatcherHtml", new DispatcherServlet(webContextHtml));
        dispatcherHtml.setLoadOnStartup(1);
        dispatcherHtml.addMapping("*.html");

        // dispatcherJsp
        AnnotationConfigWebApplicationContext webContextJsp = new AnnotationConfigWebApplicationContext();
        webContextJsp.setParent(rootContext);
        webContextJsp.register(JspConfig.class);
        ServletRegistration.Dynamic dispatcherJsp = servletContext.addServlet("dispatcherJsp", new DispatcherServlet(webContextJsp));
        dispatcherJsp.setLoadOnStartup(1);
        dispatcherJsp.addMapping("*.jsp");
    }
}

HtmlConfig

@ComponentScan("org.spring.webmvc.configuration.html")
@EnableWebMvc
@Configuration
public class HtmlConfig {

    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/html/");
        viewResolver.setSuffix(".html");
        return viewResolver;
    }
}

HtmlController

@Controller
public class HtmlController {

    @RequestMapping("/index.html")
    public String index() {
        return "index";
    }
}

JspConfig

@ComponentScan("org.spring.webmvc.configuration.jsp")
@EnableWebMvc
@Configuration
public class JspConfig {

    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }
}

JspController

@Controller
public class JspController {

    @RequestMapping("/index.jsp")
    public String index() {
        return "index";
    }
}

当然，index.html和index.jsp文件都是在WEB-INF目录下的正确文件夹中创建的。不过，如果我尝试调用/index.html或index.jsp页面，我会收到一条没有映射的警告消息。

警告[http-apr-8080-exec-3]   org.springframework.web.servlet.PageNotFound.noHandlerFound没有映射   找到带有URI [/WEB-INF/html/index.html]的HTTP请求   DispatcherServlet，名称为＆＃39; dispatcherHtml＆＃39;

警告[http-apr-8080-exec-10]   org.springframework.web.servlet.PageNotFound.noHandlerFound没有映射   找到带有URI [/WEB-INF/jsp/index.jsp]的HTTP请求   DispatcherServlet，名称为＆＃39; dispatcherJsp＆＃39;

因此，添加了两个调度程序servlet，并且控制器方法按预期运行，但由于某种原因，无法加载页面。有什么想法我错了吗？

我尝试将/ WEB-INF / html / *和/ WEB-INF / jsp / *文件夹添加到映射中，但它没有解决问题。
