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

</build>
</project>
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";
}
}
