后端代码
Controller
package com.example.knife.entity;
import lombok.Data;
@Data
public class User {
private Integer age;
private String name;
private String email;
}
Entity
package com.example.knife.controller;
import com.example.knife.entity.User;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class UserController {
@GetMapping("user")
public String user(Model model) {
User user = new User();
user.setAge(25);
user.setEmail("abc@qq.com");
user.setName("Tony");
model.addAttribute("userInfo", user);
return "user";
}
}
前端代码
user.ftl（resources/templates目录下）
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>FreeMarker 实验</title>
<style>
table,td {
border: black 1px solid;
}
</style>
</head>
<body>
<table>
<tr>
<td>姓名</td>
<td>年龄</td>
<td>Email</td>
</tr>
<tr>
<td>${userInfo.name}</td>
<td>${userInfo.age}</td>
<td>${userInfo.email}</td>
</tr>
</table>
</body>
</html>

修改Controller
package com.example.knife.controller;
import com.example.knife.entity.User;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.ArrayList;
import java.util.List;
@Controller
public class UserController {
@GetMapping("users")
public String users(Model model) {
List<User> userList = new ArrayList<>();
User user1 = new User();
user1.setAge(25);
user1.setEmail("abc@qq.com");
user1.setName("Tony");
User user2 = new User();
user2.setAge(26);
user2.setEmail("ddd@qq.com");
user2.setName("Peter");
userList.add(user1);
userList.add(user2);
model.addAttribute("userInfos", userList);
return "users";
}
}
添加users.ftl（resources/templates目录）
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>FreeMarker 实验</title>
<style>
table,td {
border: black 1px solid;
}
</style>
</head>
<body>
<table>
<tr>
<td>姓名</td>
<td>年龄</td>
<td>Email</td>
</tr>
<#list userInfos as userInfo>
<tr>
<td>${userInfo.name}</td>
<td>${userInfo.age}</td>
<td>${userInfo.email}</td>
</tr>
</#list>
</table>
</body>
</html>
