1.创建webapp目录如图所示

2.配置该目录为web目录

3.pom.xml中添加jsp依赖

<dependency>
      <groupId>org.apache.tomcat.embed</groupId>
      <artifactId>tomcat-embed-jasper</artifactId>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
    </dependency>

4.application.yml中配置前后缀

server:
  port: 9999


spring:
  freemarker:
    cache: false

  thymeleaf:
    cache: true

  devtools:
    restart:
      enabled: true
      additional-paths: src/main/java
      exclude: WEB-INF/**
  mvc:
    view:
      prefix: /WEB-INF/jsp/
      suffix: .jsp

5. controller层简单应用示例

@RequestMapping("/jsp/index")
    public ModelAndView getIndex(ModelAndView modelAndView){
        modelAndView.setViewName("index");
        modelAndView.addObject("userlist",userDao.allConditionSelectUser());
        return modelAndView;
    }
