SpringBoot整合Freemarker

由于JSP已经被淘汰,现在基本不会去使用JSP,一般springboot会使用的页面有freemarker模板和thymeleaf模板。

可以了解一下整合freemarker模板,下一篇再说thymeleaf模板,我一般使用的是thymeleaf模板,后缀名是html看着就舒服,而且官方也是推荐使用thymeleaf模板。

好了,不说那么多了,开始整合freemarker模板吧

首先需要在pom文件中添加freemarker依赖项,但是也要web启动器,不然,你会发现你用@Controller注解都用不了

pom.xml

<!-- web启动器-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- freemarker启动器 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>

创建一个ftl文件,作为页面,当然是放在resources下的templates下,因为springboot默认访问页面的地址就在这里。

userList.ftl

<html>
	<head>
		<title>展示用户数据</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>

controller控制的设置访问页面

UserController

package com.kevin.controller;

import java.util.ArrayList;
import java.util.List;

import com.kevin.entity.Users;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @author kevin
 * @version 1.0
 * @description     springboot整合freemarker
 * @createDate 2019/3/13
 */
@Controller
public class UserController {

	// 访问地址: localhost:8080/showUser
	/*
	 * 处理请求,产生数据
	 */
	@RequestMapping("/showUser")
	public String showUser(Model model){
		List<Users> list = new ArrayList<>();
		list.add(new Users(1,"张三",20));
		list.add(new Users(2,"李四",22));
		list.add(new Users(3,"王五",24));
		
		//需要一个Model对象
		model.addAttribute("list", list);
		//跳转视图
		return "userList";
	}
}

实体类

package com.kevin.entity;

/**
 * @author kevin
 * @version 1.0
 * @description     
 * @createDate 2019/3/13
 */
public class Users {
	
	private Integer userid;
	private String username;
	private Integer userage;

	public Users() {
	}
	
	public Users(Integer userid, String username, Integer userage) {
		super();
		this.userid = userid;
		this.username = username;
		this.userage = userage;
	}
	
	public Integer getUserid() {
		return userid;
	}
	public void setUserid(Integer userid) {
		this.userid = userid;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public Integer getUserage() {
		return userage;
	}
	public void setUserage(Integer userage) {
		this.userage = userage;
	}
	
}

启动类

package com.kevin;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author kevin
 * @version 1.0
 * @description     springboot整合freemarker
 * @createDate 2019/3/13
 */
@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

整体的目录

访问页面看看:localhost:8080/showUser

可以访问,证明整合成功。
