springboot 添加 jsp 支持
一、在pom文件中添加依赖
<dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency>
二、在application.yml文件中添加配置
spring: mvc: view: prefix: /WEB-INF/view/ suffix: .jsp
三、修改项目文件夹结构以下
新建webapp、WEB-INF、view文件夹html
四、在view文件夹下新建 index.jsp文件
jsp内容以下:java
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>springboot添加jsp支持</title> </head> <body> ${username} <table border="1"> <tr> <th>序号</th> <th>用户名</th> <th>用户ID</th> <th>帐号</th> </tr> <c:forEach items="${requestScope.users}" var="user" varStatus="id"> <tr> <td>${id.index}</td> <td>${user.userName}</td> <td>${user.userId}</td> <td>${user.userCode}</td> </tr> </c:forEach> </table> </body> </html> <%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>springboot添加jsp支持</title> </head> <body> ${username} <table border="1"> <tr> <th>序号</th> <th>用户名</th> <th>用户ID</th> <th>帐号</th> </tr> <c:forEach items="${requestScope.users}" var="user" varStatus="id"> <tr> <td>${id.index}</td> <td>${user.userName}</td> <td>${user.userId}</td> <td>${user.userCode}</td> </tr> </c:forEach> </table> </body> </html>五、编写实体类
public class User { private String userId; private String userName; private String userCode; public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserCode() { return userCode; } public void setUserCode(String userCode) { this.userCode = userCode; } @Override public String toString() { return "User [userId=" + userId + ", userName=" + userName + ", userCode=" + userCode + "]"; } public class User { private String userId; private String userName; private String userCode; public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserCode() { return userCode; } public void setUserCode(String userCode) { this.userCode = userCode; } @Override public String toString() { return "User [userId=" + userId + ", userName=" + userName + ", userCode=" + userCode + "]"; }六、编写controller
@Controller public class TestController { @RequestMapping(value = "/test") public String test(Model model) { model.addAttribute("username", "明月几时有"); model.addAttribute("users", setList()); return "index"; } //封装list public List<User> setList(){ List<User> lists = new ArrayList<User>(); User user1 = new User(); user1.setUserId("1"); user1.setUserCode("001"); user1.setUserName("苏轼"); lists.add(user1); User user2 = new User(); user2.setUserId("2"); user2.setUserCode("002"); user2.setUserName("李白"); lists.add(user2); User user3 = new User(); user3.setUserId("3"); user3.setUserCode("003"); user3.setUserName("杜甫"); lists.add(user3); User user4 = new User(); user4.setUserId("4"); user4.setUserCode("004"); user4.setUserName("白居易"); lists.add(user4); return lists; } } @Controller public class TestController { @RequestMapping(value = "/test") public String test(Model model) { model.addAttribute("username", "明月几时有"); model.addAttribute("users", setList()); return "index"; } //封装list public List<User> setList(){ List<User> lists = new ArrayList<User>(); User user1 = new User(); user1.setUserId("1"); user1.setUserCode("001"); user1.setUserName("苏轼"); lists.add(user1); User user2 = new User(); user2.setUserId("2"); user2.setUserCode("002"); user2.setUserName("李白"); lists.add(user2); User user3 = new User(); user3.setUserId("3"); user3.setUserCode("003"); user3.setUserName("杜甫"); lists.add(user3); User user4 = new User(); user4.setUserId("4"); user4.setUserCode("004"); user4.setUserName("白居易"); lists.add(user4); return lists; } }七、测试代码
浏览器访问 http://localhost:8080/testweb
