一. SpringBoot 整合 jsp 技術
1.創建maven項目
2.修改 pom 文件，添加座標
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.0.RELEASE</version>
</parent>
<groupId>com.kennosaur</groupId>
<artifactId>springboot-hello</artifactId>
<version>0.0.1-SNAPSHOT</version>
<!-- 修改jdk版本號 <properties> <java.version>1.8</java.version> </properties> -->
<!-- Add typical dependencies for a web application -->
<dependencies>
<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>
</project>
3.創建 springBoot 的全局配置文件，application.properties
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
4.創建 Controller
package com.bjsxt.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.bjsxt.pojo.Users;
/**
* SpringBoot整合jsp
*
*
*/
@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
<%@ 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
package com.bjsxt;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* SpringBoot啓動類
*
*
*/
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
二. SpringBoot 整合 Freemarker
1,創建項目
2,修改 pom 添加座標
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.0.RELEASE</version>
</parent>
<groupId>com.kennosaur</groupId>
<artifactId>springboot-hello</artifactId>
<version>0.0.1-SNAPSHOT</version>
<!-- 修改jdk版本號 <properties> <java.version>1.8</java.version> </properties> -->
<!-- Add typical dependencies for a web application -->
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- freemarker 啓動器的座標 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
</dependencies>
</project>
3,編寫視圖 userList.ftl
注意：springBoot 要求模板形式的視圖層技術的文件必須要放到 src/main/resources 目錄下必須要一個名稱爲 templates
<html>
<head>
<title>展示用戶數據</title>
<meta charset="utf-9"></meta>
</head>
<body>
<table border="1" align="center" width="50%">
<tr>
<th>ID</th>
<th>Name</th>
<th>Age</th>
</tr>
<#list list as user >
<tr>
<td>${user.userid}</td>
<td>${user.username}</td>
<td>${user.userage}</td>
</tr>
</#list>
</table>
</body>
</html>
4,創建 Controller---同jsp
5,創建啓動器----同jsp
