我的控制器 

package controller;

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

@Controller
public class indexController {

    @RequestMapping("/index")
    public ModelAndView myindex(){
        return new ModelAndView("index.jsp");
    }
}

我的主要 

package earthbnb;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringBootWebApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {

        SpringApplication.run(SpringBootWebApplication.class, args);
    }

    @Overridehttps://stackoverflow.com/posts/46391915/edit#
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootWebApplication.class);
    }


}

我也添加了

spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp

到src/main/resources/application.properties.

to the src/main/resources/application.properties.

jsp页面位于src/main/webapp/WEB-INF/jsp/如果您需要其他任何信息，请告诉我.

the jsp pages are inside src/main/webapp/WEB-INF/jsp/If you need any other info let me know.

任何帮助将不胜感激...

Any help would be appreciated...

推荐答案

您正在使用spring-boot依赖项，然后将使用传统的XML文件.
这直接来自于文档- Spring Boot倾向于使用约定而不是配置，并且旨在使您尽快启动并运行.
首先要弄清楚，您要去Spring-MVC还是Spring-Boot项目.
要从Spring Boot应用程序中为JSPs提供服务器，您可以看到我现有的答案
spring boot控制器无法访问jsp视图

You are using spring-boot dependencies and then you are going for the traditional XML files.
This is straight from the docs- Spring Boot favors convention over configuration and is designed to get you up and running as quickly as possible.
First get the clarity, Do you want to go for Spring-MVC or a Spring-Boot project.
To server the JSPs from a spring boot application you can see this existing answer of mine
spring boot controller can't reach to jsp view

更新-在OP更新问题时，我正在添加所需的更改，以使其正常运行..

项目目录结构

pom.xml-包含最低要求的依赖项(如果您不是其他应用程序服务器，则将tomcat排除在外).您可以根据需要添加最小的依赖项.

pom.xml - contains minimum required dependency(exclusion of tomcat is done if you are not some other application server). It is having minimum dependencies you can add as per your need.

The Main class

The Main class 

package com;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringBootWebApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {

        SpringApplication.run(SpringBootWebApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootWebApplication.class);
    }

}

索引控制器-(您应该在@RestContoller此处使用更具体的注释，以便在@Controller也可以正常工作时使用它的具体注释)此外，这里的视图名称应仅包含name，您的代码还应包含.jsp扩展名. 

package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class IndexController {

    @RequestMapping("/index")
    public ModelAndView myindex() {
        return new ModelAndView("index");
    }
}

application.properties 

spring.mvc.view.prefix:/WEB-INF/jsp/
spring.mvc.view.suffix:.jsp
server.port=8081

我不确定您是否要使用嵌入式tomcat或其他某些应用程序服务器，例如Glassfish，WLP或Weblogic.即使您是其他服务器，也只需转到项目目录并使用以下命令构建war文件

I am not sure are you going to use embedded tomcat or some other application server like Glassfish,WLP or Weblogic. Even if you are some other server then just go to project directory and build the war file by using below command

mvn clean install

它将在目标文件夹内创建war，您可以将其放置在您选择的应用服务器中.

It will create the war inside target folder which you can put in application server of your choice.
