springboot不推荐使用jsp,默认使用的是Thymeleaf模板。不过，如果你一定要使用jsp，需要做一些配置。

## application.properties ##

指定jsp文件的位置在/WEB-INF/jsp/

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

## 应用启动类 ##

@SpringBootApplication
    public class Application extends SpringBootServletInitializer { 
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            return builder.sources(Application.class);
        }
        public static void main( String[] args )
        {
            SpringApplication.run(Application.class, args);
        }
    }

## 测试controller ##

@Controller
    public class TestController { 
        @RequestMapping(value = {
       "","/test"})
        public ModelAndView index(ModelAndView mv) {
            mv.setViewName("/test");
            mv.addObject("msg","你好，世界！");
            return mv;
        }
    }

## 测试页面 ##

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>Test Page</title>
    </head>
    <body>
      ${msg}
    </body>
    </html>

## 部署测试 ##

在idea的tomcat中添加该web项目，启动tomcat。

可以看到，测试成功。

## 注意事项 ##

由于jsp的性能比较低，spring推荐使用Thymeleaf模板，spring的官网即是使用的该模板。
