【SpringBoot】09.SpringBoot整合Freemarker

SpringBoot整合Freemarker

1.修改pom文件，添加坐标freemarker启动器坐标

<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>2.1.2.RELEASE</version>
  </parent>
  <groupId>com.dxh</groupId>
  <artifactId>09-spring-boot-view-freemarker</artifactId>
  <version>0.0.1-SNAPSHOT</version>
    <!-- 修改JDK版本 -->
  <properties>
  	<java.version>1.8</java.version>
  </properties>
  <dependencies>
		<!-- Spring Boot 的启动器 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<!-- freemarker启动器坐标 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-freemarker</artifactId>
		</dependency>
	</dependencies>
</project>

2.编写视图：SpringBoot要求模板形式的视图层技术的文件必须放在src/main/resources/目录下必须要一个名称为：templates目录。 视图名为userList.ftl

<html>
	<head>
		<title>展示用户数据</title>
		<meta charset="utf-8"></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>

3.创建controller、POJO

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.dxh.pojo.Users;

/**
 * SpringBoot整合jsp
 *
 */
@Controller
public class UserController {
	/**
	   * 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,"赵武",25));
		//需要一个Model对象
		model.addAttribute("list",list);
		//跳转视图
		return "userList";
	}
}


package com.dxh.pojo;
public class Users {
	private Integer userId;
	private String userName;
	private Integer userAge;
	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;
	}	
}

4.创建启动器——运行
