SpringBoot學習筆記(5)——SpringBoot整合jsp技術
1. 創建項目
2. 修改pom文件，添加座標
<dependencies>
<!-- springBoot的啓動器 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- jstl -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!-- jasper -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
</dependencies>
3. 創建springBoot的全局配置文件:application.properties
application.properties:
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
4. 創建Controller
@Controller
public class UserController {
/*
* 處理請求，產生數據
*/
@RequestMapping("/showUser")
public String showUser(Model model){
List<Users> list = new ArrayList<>();
list.add(new Users(1,"張三",20));
list.add(new Users(2,"李四",22));
list.add(new Users(3,"王五",24));
//需要一個Model對象
model.addAttribute("list", list);
//跳轉視圖
return "userList";
}
}
5. 創建jsp
userList.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!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>Insert title here</title>
</head>
<body>
<table border="1" align="center" width="50%">
<tr>
<th>ID</th>
<th>Name</th>
<th>Age</th>
</tr>
<c:forEach items="${list }" var="user">
<tr>
<td>${user.userid }</td>
<td>${user.username }</td>
<td>${user.userage }</td>
</tr>
</c:forEach>
</table>
</body>
</html>
6. 創建啓動類
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
7.運行
運行App.java啓動SpringBoot，在瀏覽器端訪問localhost:8080/showUser
