步骤
- 创建项目
- 修改POM文件，添加Freemarker启动器
- 创建Controller
- 创建Users实体
- 添加Freemarker文件配置
- 创建视图
Freemarker也是视图层技术，与Thymeleaf相似，他们都被称为模板视图
添加Freemarker依赖
<!--Freemarker启动器依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
创建User实体类
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;
}
}
创建Controller
/**
* UserController
*/
@Controller
public class UsersController {
/**
* 处理请求，返回数据
*/
@GetMapping("/showUsers")
public String showUsers(Model model){
List<Users> list = new ArrayList<>();
list.add(new Users("admin","F","32"));
list.add(new Users("lili","m","23"));
model.addAttribute("list",list);
return "usersList";
}
}
添加配置
spring.freemarker.suffix=.ftl
创建视图
<!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>
