Thymeleaf
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>在模板中加入解析
<!DOCTYPE html>
<html lang="zh_cn" xmlns:th="http://www.thymeleaf.org/"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity5">
后面这个是要用到spring security的相关数据时要用到的命名空间，暂且不提。?
application.properties文件中关于thymeleaf的配置项
spring.thymeleaf.model=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
spring.thymeleaf.cache=false常用th标签
<p th:text="${name}"></p>
显示文本th:object
<p th:object="${object}"></p>
显示对象th:action
<form th:action="@{/person/}+${person.id}" method="post"></form>
用于指定表单提交地址th:value
th:field
URL写法
th:href="@{http://www.baidu.com}"
th:href="@{/}"
th:href="@{css/bootstrap.min.css}"
条件求值
th:if th:unless
th:switch
th:case
运算符
+ - * /
<p th:text="1+2"></p>遍历
th:each
<div th:each="item:${items}">
<span th:text="${item.name}"></span>
</div>处理公共代码
th:fragment th:include th:replace
新建一个简单的model类 User
public class User {
private long id;
private String name;
private int age;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}创建控制器UserController
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.ArrayList;
import java.util.List;
@Controller
public class UserController {
@GetMapping("/user")
public ModelAndView hello(){
List<User> list = new ArrayList<User>();
User user = new User();
user.setName("张三");
user.setAge(17);
list.add(user);
User lisi = new User();
lisi.setName("李四");
lisi.setAge(19);
list.add(lisi);
User wangwu = new User();
wangwu.setName("王五");
wangwu.setAge(19);
list.add(wangwu);
ModelAndView model = new ModelAndView("user");
model.addObject("users",list);
return model;
}
}这里的model的名字就是html文件的名字，一开始没搞明白。
创建view 就是html user.html
<!DOCTYPE html>
<html lang="zh_cn" xmlns:th="http://www.thymeleaf.ort">
<head>
<meta charset="UTF-8">
<title>this is user test page</title>
</head>
<body>
<table border="1">
<tr>
<th>姓名</th>
<th>年龄</th>
</tr>
<tr th:each="user : ${users}">
<td th:text="${user.name}"></td>
<td th:text="${user.age}"></td>
</tr>
</table>
</body>
</html>运行显示。
