SpringBoot整合freemarker
1.添加依賴：springboot基本上是無縫銜接，基本上只需要添加對應的依賴，不需要或者做很少量的配置即可
注：對於springboot項目的創建此處不做說明
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
2.創建controller
/**
* springboot整合freemarker
*/
@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";
}
}
3.創建bean
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;
}
}
4.創建freemarker文件(使用idea創建后綴名 .ftl 的文件)
在templates文件夾下創建 userInfo.ftl 文件，如果我們不在application.properties更改配置，則springboot會默認自動去templates尋找相關的文件
<!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>年齡</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只是一種模板引擎，你可以將其當成另外一種很類似於jsp的語法的html文件- 很可能出現的錯誤：路由配置正確，但是就是出現
404錯誤，可能原因是需要在配置文件中配置application.properties，指定文件的后綴名.ftl，因為springboot默認的后綴名很可能不是這個
spring.freemarker.suffix=.ftl
5.以上就是基本的整合配置步驟
SpringBoot整合thymeleaf
1.添加依賴，創建controller，bean等，和上面一樣，代碼如下
2. 添加依賴
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
3.創建controller
/**
* springboot整合thymeleaf
*/
@Controller
public class StudentController {
@GetMapping("/student")
public String stu(Model model){
ArrayList<Student> students = new ArrayList<>();
for (int i = 0 ;i < 10 ; i++) {
Student student = new Student();
student.setId(i);
student.setUsername("shanggushenlong>>" + i);
student.setAge(String.valueOf(i));
students.add(student);
}
model.addAttribute("students",students);
return "student";
}
}
4.創建bean
public class Student {
private Integer id;
private String username;
private String age;
@Override
public String toString() {
return "StudentController{" +
"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 String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
}
5.創建html文件（thymeleaf模板引擎后綴名 .html）
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html xmlns:th="http://www.w3.org">
<head>
<title>Title</title>
</head>
<body>
<table border="1">
<tr>
<td>id</td>
<td>username</td>
<td>age</td>
</tr>
<tr th:each="stu : ${students}">
<td th:text="${stu.id}"></td>
<td th:text="${stu.username}"></td>
<td th:text="${stu.age}"></td>
</tr>
</table>
</body>
</html>
