無法使用Spring引導

我在春季啓動新來渲染JSP，我想先從一個簡單的例子，但似乎沒有任何工作這是我的控制器：無法使用Spring引導

Package controller; 
import org.springframework.stereotype.Controller; 
import org.springframework.ui.Model; 
import org.springframework.web.bind.annotation.RequestMapping; 
@Controller 
public class testController { 
RequestMapping("view/aboutus") 
public String greeting(Model model) { 
model.addAttribute("name", "azertyyyy"); 
    return "aboutus"; }}

，這是JSP視圖：

<%@ page language="java" contentType="text/html; charset=UTF-8" 
pageEncoding="UTF-8"%> 
    <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%> 
<!DOCTYPE> 
<html> <body> ${name} 


<p>hello world</p> </body></html>

我添加所需依賴關係：

<dependency> 
<groupId>javax.servlet</groupId> 
<artifactId>jstl</artifactId> 
<version>1.2</version> 


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

和我添加前綴和後綴在application.properties

當我運行應用程序只有你好世界顯示在沒有名稱變量的視圖，在這裏搜索後，我將視圖目錄從src/main/webapp/view更改爲src/main/resource /模板，但彈簧引導無法找到視圖

我可以添加一些細節，如果有什麼不明確 –

我不確定您是否完全知道我們必須作出的變化，當我們想運行應用程序作爲戰爭包。

將包裝更改爲從jar打包並需要依賴關係。
更改主應用程序類擴展SpringBootServletInitializer並實現配置（）
定義JSP頁面的路徑應用性能
把JSP頁面中正確的路徑（web應用/ WEB-INF/jsp的檢查截屏）

以下目錄結構是代碼的變化我必須做的運行JSP

主類

package com.exception; 

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); 
    } 


}

休息控制器 - 它重定向到JSP

package com.exception.controller; 

import java.util.Map; 

import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.RestController; 

@RestController 
@RequestMapping(method = RequestMethod.GET) 
public class TestExceptionController { 

    @RequestMapping("/") 
    public String welcome(Map<String, Object> model) { 

     System.out.println("in controller"); 

     model.put("message", "hello spring boot"); 

     return "welcome"; 
    } 

}

application.properties - 定義對JSP

server.port=8085 
spring.mvc.view.prefix: /WEB-INF/jsp/ 
spring.mvc.view.suffix: .jsp

路徑
