1.在pom.xml文件中添加依賴：
<!-- Servlet依賴 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
<!-- jstl -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!-- Jasper是tomcat中使用的JSP引擎 -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
2.配置屬性：在application.properties文件添加如下屬性：
# JSP頁面默認前綴目錄 spring.mvc.view.prefix=/WEB-INF/jsp/ # JSP響應頁面默認后綴 spring.mvc.view.suffix=.jsp
其實完全可以省略這一步驟。
3.編寫Controller類：
package com.yws710.springboot.demo1.controller; import com.yws710.springboot.demo1.domain.User; import com.yws710.springboot.demo1.service.UserService; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import java.util.List; /** * User控制器類 */ @Controller @RequestMapping("/user") public class UserController { private final UserService userService; private static final Logger LOGGER = LoggerFactory.getLogger(UserController.class); @Autowired public UserController(UserService userService) { this.userService = userService; } @RequestMapping("/list") public ModelAndView userList() throws Exception { LOGGER.warn("您執行了UserController類中的userList()方法。"); ModelAndView mv = new ModelAndView(); List<User> userList = userService.userList(); mv.addObject("userList", userList); mv.setViewName("/user/list"); return mv; } }
4.創建jsp文件。WEB-INF/jsp/user/list.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <base href="<%=basePath%>"> <title>用戶列表</title> <link rel="stylesheet" href="/css/main.css" /> </head> <body> <table> <thead> <tr> <th>ID</th> <th>姓名</th> <th>生日</th> <th>薪資</th> </tr> </thead> <tbody> <c:forEach items="${userList}" var="user" varStatus="status"> <tr> <td>${user.id}</td> <td>${user.name}</td> <td><fmt:formatDate value="${user.birthday}" pattern="yyyy-MM-dd HH:mm:ss"/></td> <td>${user.salary}</td> </tr> </c:forEach> </tbody> </table> </body> </html>
5.啟動項目，查看運行結果：
