Java 如何在Intellij中运行导入的Spring mvc项目？

我使用IntelliJ并导入了Spring MVC项目。我配置了maven安装程序并使用mvn clean install来构建我的项目。为了运行，我配置了tomcat:run on the configuration of IntelliJ。但红色标记显示为：

配置类：

package com.luv2code.springsecurity.demo.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.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.luv2code")
public class DemoAppConfig {

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




}

调度程序Servlet配置

package com.luv2code.springsecurity.demo.config;


import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class MySpringMVcDispatcherServletInitilizer extends AbstractAnnotationConfigDispatcherServletInitializer {


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

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

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


}

在DemoController中，showHome应返回ModelAndView 类似这样的内容，然后ViewResolver将其映射到home.jsp

您还可以参考更多详细信息

尝试执行以下操作： 文件->项目结构->模块->检查是否添加了Web模块 如果“否”： 1.添加此模块。然后见第2点。 如果“是”： 检查此处的Web资源目录：

---

2.它必须指向您到webapp目录的路径。

在控制器中，修改getmapping，如@getmapping和tryno cnanges In output是否可以尝试@Getmappinghome和ping URL之类的操作并重试？如果不起作用，请在servlet配置中删除，在getServletMappings方法中使用空字符串而不是/否其未运行红色标记显示为Dependency not found。请看我上传的图片，你想解析1。红色标记问题或2。当您点击时，您无法看到您的jsp。根据控制台日志，您的应用程序已启动并正在运行。当我点击URL时，我没有看到jsp。为什么红色标记会显示。。它不在eclipse中显示，但在intellij上显示

package com.luv2code.springsecurity.demo.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.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.luv2code")
public class DemoAppConfig {

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




}

    }

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


}

@RequestMapping("/")
public ModelAndView showHome() {
    return new ModelAndView("home");
