Spring Boot整合JSP和Freemarker
写在前面
从零开始的Spring Boot(3、Spring Boot静态资源和文件上传)
https://www.cnblogs.com/gaolight/p/13130406.html
一、Spring Boot整合JSP
- 创建工程springbootjsp
- 修改POM文件，添加JSP引擎和JSTL依赖
<!--添加jsp引擎-->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<!--添加JSTL坐标依赖-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
3.在main下创建webapp文件夹，依次点击下图红方框，将webapp标记为web目录
4.在JSP下创建index.jsp，修改代码，
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h2>Hello JSP</h2>
</body>
</html>
5.修改配置文件application.properties，配置视图解析器
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
6.如图，创建PageController类，修改代码；
package com.demo.springbootjsp.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
@Controller
public class PageConntroller {
@GetMapping("/{page}")
public String showPage(@PathVariable String page){
return page;
}
}
7.运行启动类，得到
如果项目结构为聚合工程，则在运行jsp时是需要指定路径的，如果是独立工程则不需要
二、Spring Boot整合Freemarker
- 创建springbootfreemarker工程
- 修改POM文件，添加Freemarker启动器
<!--添加Freemarker启动器依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
3.创建Users实体
如图，建立Users类，并修改代码；
package com.demo.springbootfreemarker.pojo;
public class Users {
private String username;
private String usersex;
private String userage;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getUsersex() {
return usersex;
}
public void setUsersex(String usersex) {
this.usersex = usersex;
}
public String getUserage() {
return userage;
}
public void setUserage(String userage) {
this.userage = userage;
}
public Users(String username, String usersex, String userage) {
this.username = username;
this.usersex = usersex;
this.userage = userage;
}
public Users() {
}
}
4.创建controller
创建UsersController类，修改代码；
5.创建userList.ftl，修改代码；
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<table border="1" align="center" width="50%">
<tr>
<th>Name</th>
<th>Sex</th>
<th>Age</th>
</tr>
<#list list as user>
<tr>
<td>${user.username}</td>
<td>${user.usersex}</td>
<td>${user.userage}</td>
</tr>
</#list>
</table>
</body>
</html>
6.在application.properties中配置：spring.freemarker.suffix=.ftl
7.运行启动类，得到
