注：对于springboot项目的创建此处不做说明
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
/**

*/
@Controller
public class UserController {
@GetMapping("/user")
public String user(Model model){
List<User> list = new ArrayList<>();
for (int i = 0 ; i < 10 ; i++){
User user = new User();
user.setId(i);
user.setUsername("shangushenlong>>"+i);
user.setAge(i);
list.add(user);
}
model.addAttribute("users",list);
return "userInfo";
}
}
public class User {
private Integer id;
private String username;
private Integer age;
@Override
public String toString() {
return "User{" +
"id=" + id +
", username=‘" + username + ‘\‘‘ +
", age=" + age +
‘}‘;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
在templates文件夹下创建 userInfo.ftl 文件，如果我们不在application.properties更改配置，则springboot会默认自动去templates寻找相关的文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<table border="1">
<tr>
<td>id</td>
<td>姓名</td>
<td>年龄</td>
</tr>
<#list users as user>
<tr>
<td>${user.id}</td>
<td>${user.username}</td>
<td>${user.age}</td>
</tr>
</#list>
</table>
</body>
</html>
注意:
freemarker只是一种模板引擎，你可以将其当成另外一种很类似于jsp的语法的html文件404错误，可能原因是需要在配置文件中配置application.properties，指定文件的后缀名 .ftl，因为springboot默认的后缀名很可能不是这个spring.freemarker.suffix=.ftl
