## 简介： ##

官方不推荐使用jsp作为页面,我们可以使用其他的模板引擎，比如 Thymeleaf 和 freemarker，官方主推的是Thymeleaf。但是目前来说,很多项目的页面还是用的jsp.而且很多现成的项目用的jsp页面,扒过来就能用,当然如果时间允许的情况，还是不建议大家使用jsp，而是采用官方推荐的模板。

## 搭建项目 ##

### 1.新建一个基础的 springboot WEB项目 ###

### 2.pom.xml文件jar包 ###

在这里插入代码片

### 3. 新建webapp文件夹，与resources同级 ###

### 4. 新建JSP页面，此时发现New里面没有JSP页面。需要设置一下才会出现 ###

### 添加web ###

### 选择已经添加的webapp ###

### 此时webapp上有蓝色圆点，表示设置成功 ###

### 5.application.properties ###

```server.port=8082
    
    #页面默认前缀目录 默认在webapp下有别的文件夹可以，以文件夹/往下加
    spring.mvc.view.prefix=/
    #页面默认后缀目录
    spring.mvc.view.suffix=.jsp``

## 简单Demo ##

### 6.JspController.java ###

import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.GetMapping;
    
    /**

    @Controller
    public class JspController {
        @GetMapping("/boot/index")
        public String index(Model model){
            model.addAttribute("msg","Spring boot集成jsp");
            return "index";
        }
        @GetMapping("/boot/aaa")    
        public String aaa(Model model){
            model.addAttribute("sss","boot 整合jsp");
            return "aaa";
        }
