springBoot引入JSP文件相应配置

(1)首先导入依赖

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

(2)在application.yml文件中进行配置 ,下面mvc子树下的配置(标红区域)

spring:
  profiles:
    active: prod
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/recruit?useUnicode=true&characterEncoding=UTF-8
    username: root
    password: admin
  jpa:
    hibernate:
      ddl-auto: update
    show-sql: true
  mvc:
    view:
      prefix: /WEB-INF/views/
      suffix: .jsp

(3)目录结构如图：

(4)然后启动文件Application里实现SpringBootServletInitializer类并重写SpringApplicationBundler方法

@SpringBootApplication
public class RecruitApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(RecruitApplication.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(RecruitApplication.class, args);
    }
}

(5)在对应的controller层中书写代码时，返回值改为与SpringMVC一样的用法，返回String或者ModelAndView进行Jsp文件的跳转，如：

@GetMapping(value = "/getAllStudent")
   public ModelAndView getAllStudent(){
       ModelAndView modelAndView = new ModelAndView();
       List<Student> list = stuService.getAllStu();
       modelAndView.addObject("students",list);
       modelAndView.setViewName("index");
       return modelAndView;
   }
