(The structure can be designed by itself, no need to follow this demo), directory structure
Configuration fileIn the configuration file, configure the newly created directory, along with the JSP file suffix, configured as follows:
New Controllerserver.port=8888spring.mvc.view.prefix=/WEB-INF/jsp/spring.mvc.view.suffix=.jsp
Create a Indexcontroller that writes a jump method with the following code:
Create a JSPpackage com.dalaoyang.controller;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.GetMapping;/** * @author dalaoyang * @project springboot_learn * @package com.dalaoyang.controller * @email [email protected] * @date 2018/8/13 */@Controllerpublic class IndexController { @GetMapping("/") public String index(Model model){ model.addAttribute("name", "dalaoyang"); return "index"; }}
Create a new index.jsp below src/main/webapp/web-inf/jsp with the following code:
<!DOCTYPE html>
Run Tests
