                <resource>

                </plugin>
            </plugins>
        </build>
    
    </project>

2.配置资源文件夹

在src/main文件夹下面新建文件夹 webapp

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTIwNDUwNDU_size_16_color_FFFFFF_t_70][]

并将webpp设置成web资源文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTIwNDUwNDU_size_16_color_FFFFFF_t_70 1][]

这样的话webapp文件夹上面就有一个小蓝点了，这样表示设置成功了。

3.配置视图解析的前缀与后缀

在application.properties文件里面配置

spring.mvc.view.prefix=/jsp/
    spring.mvc.view.suffix=.jsp

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTIwNDUwNDU_size_16_color_FFFFFF_t_70 3][]

4.新建jsp文件

在webapp文件夹下面新建jsp文件夹，并在jsp文件夹下面新建index.jsp文件。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTIwNDUwNDU_size_16_color_FFFFFF_t_70 4][]

5.编写控制器

package com.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    
    /**
     * index控制类
     *
     * @Package: com.controller
     * @ClassName: IndexController
     * @author: zq
     * @since: 2020/6/7 15:54
     * @version: 1.0
     * @Copyright: 2020 zq. All rights reserved.
     */
    @Controller
    public class IndexController {
    
        @RequestMapping("/index")
        public ModelAndView index() {
    
            ModelAndView modelAndView = new ModelAndView();
            modelAndView.setViewName("index");
            modelAndView.addObject("msg", "zhangsan");
            return modelAndView;
    
        }
    
    }

6.启动项目，验证页面

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTIwNDUwNDU_size_16_color_FFFFFF_t_70 6][]
