需要幫助在IntelliJ IDEA中使用Maven設置簡單的Spring Boot jsp應用程序

我在設置一個非常簡單的Spring啓動應用程序時遇到了問題。我嘗試了多個教程，Spring MVC，但沒有人會打開我的jsp。需要幫助在IntelliJ IDEA中使用Maven設置簡單的Spring Boot jsp應用程序

我目前能夠用Initializr設置一個項目，並且我理解@RequestMapping的概念。我能夠使用Spring Boot運行我的Tomcat服務器，但是當我打開我的http://localhost:8080/home/時，出現404錯誤的默認錯誤頁面。

感謝您的幫助。

首先改變你的POM文件是這樣的：

<dependency> 
      <groupId>org.apache.tomcat.embed</groupId> 
      <artifactId>tomcat-embed-jasper</artifactId> 

     </dependency> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-tomcat</artifactId> 
     </dependency> 
     <dependency> 
      <groupId>javax.servlet</groupId> 
      <artifactId>jstl</artifactId> 
     </dependency>

然後添加配置類：

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

@Configuration 
@EnableWebMvc 
@ComponentScan 
public class WebConfig extends WebMvcConfigurerAdapter { 

    @Override 
    public void configureViewResolvers(ViewResolverRegistry registry) { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix("/WEB-INF/"); 
     resolver.setSuffix(".jsp"); 
     resolver.setViewClass(JstlView.class); 
     registry.viewResolver(resolver); 
    } 


}
