## 一、简介 ##

springboot支持多种模版引擎包括：  
1. FreeMarker  
2. Groovy  
3. Thymeleaf （Spring 官网使用这个）  
4. Velocity  
5. JSP （貌似Spring Boot官方不推荐）

不过本文还是选择大家都熟悉的JSP来作为研究案例。

## 二、导包 ##

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

## 三、controller层 ##

@Controller
    public class ViewController { 
    
        /** * @description <p></p> * @return * @author heshiyuan * @date 2017/12/2 20:56 */
        @RequestMapping(value = {
       "/","/index"})
        public String index(HttpServletRequest request){
            request.setAttribute("content","this is index");
            request.setAttribute("time", Calendar.getInstance().getTime());
            // 自动映射到"/WEB-INF/jsp/"下
            return "index" ;
        }
    
        @RequestMapping("/toPage1View")
        public String page1(Model model){
            model.addAttribute("time",Calendar.getInstance().getTime()) ;
            model.addAttribute("content","this is page1");
            return "page/page1" ;
        }
    
        @RequestMapping("/toPage2View")
        public ModelAndView page1(ModelAndView modelAndView){
            modelAndView.setViewName("page/page2");
            modelAndView.addObject("time",Calendar.getInstance().getTime()) ;
            modelAndView.addObject("content","this is page1") ;
            return modelAndView;
        }
    }

## 四、配置文件 ##

spring.thymeleaf.cache=false
    spring.thymeleaf.enabled=false
    spring.mvc.view.prefix=/WEB-INF/jsp/
    spring.mvc.view.suffix=.jsp

## 五、配置页面 ##

index.html

<%@page contentType="text/html;charset=utf-8" language="java" %>
    <html>
    <head>
        <title>主页</title>
    </head>
    <body>
        ${content}
        ${time}
    </body>
    </html>

page/page1.jsp page/page2.jsp均是类似的页面。

## 六、启动 ##

@SpringBootApplication
    public class SpringBootJspApplication { 
        public static void main(String[] args) {
            SpringApplication.run(SpringBootJspApplication.class,args);
        }
    }
