springboot 引入 thymeleaf 模板
第一步pom中:
<!-- 引入 thymeleaf 模板依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
第二步 aplication.properties 中:
############################################################
#
# thymeleaf \u9759\u6001\u8d44\u6e90\u914d\u7f6e
# 同样这里也是 需要重新建一个文件夹放在templates下的文件
# thymeleaf与freemarkerController模板用一个就可以,没必要用两个
############################################################
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
# \u5173\u95ed\u7f13\u5b58, \u5373\u65f6\u5237\u65b0, \u4e0a\u7ebf\u751f\u4ea7\u73af\u5883\u9700\u8981\u6539\u4e3atrue
spring.thymeleaf.cache=false //这里在上线的时候要改为true
#\u8bbe\u5b9a\u9759\u6001\u6587\u4ef6\u8def\u5f84\uff0cjs,css\u7b49
spring.mvc.static-path-pattern=/static/** 这个默认本来就是这个 还有动态默认在public中
第三步前端:
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8" />
<title></title>
<!-- <script th:src="@{/static/js/test.js}"></script> -->
</head>
<body>
<div>
用户姓名：<input th:id="${user.name}" th:name="${user.name}" th:value="${user.name}"/>
<br/>
用户年龄：<input th:value="${user.age}"/>
<br/>
用户生日：<input th:value="${user.birthday}"/>
<br/>
用户生日：<input th:value="${#dates.format(user.birthday, 'yyyy-MM-dd')}"/>
<br/>
</div>
<br/>
<div th:object="${user}">
用户姓名：<input th:id="*{name}" th:name="*{name}" th:value="*{name}"/>
<br/>
用户年龄：<input th:value="*{age}"/>
<br/>
用户生日：<input th:value="*{#dates.format(birthday, 'yyyy-MM-dd hh:mm:ss')}"/>
<br/>
</div>
<br/>
text 与 utext ：<br/>
<span th:text="${user.desc}">abc</span>
<br/>
<span th:utext="${user.desc}">abc</span>
<br/>
<br/>
URL:<br/>
<a href="" th:href="@{http://www.imooc.com}">网站地址</a>
<br/>
<br/>
<form th:action="@{/th/postform}" th:object="${user}" method="post" th:method="post">
<input type="text" th:field="*{name}"/>
<input type="text" th:field="*{age}"/>
<input type="submit"/>
</form>
<br/>
<br/>
<div th:if="${user.age} == 18">十八岁的天空</div>
<div th:if="${user.age} gt 18">你老了</div>
<div th:if="${user.age} lt 18">你很年轻</div>
<div th:if="${user.age} ge 18">大于等于</div>
<div th:if="${user.age} le 18">小于等于</div>
<br/>
<br/>
<select>
<option >选择框</option>
<option th:selected="${user.name eq 'lee'}">lee</option>
<option th:selected="${user.name eq 'imooc'}">imooc</option>
<option th:selected="${user.name eq 'LeeCX'}">LeeCX</option>
</select>
<br/>
<br/>
<table>
<tr>
<th>姓名</th>
<th>年龄</th>
<th>年龄备注</th>
<th>生日</th>
</tr>
<tr th:each="person:${userList}">
<td th:text="${person.name}"></td>
<td th:text="${person.age}"></td>
<td th:text="${person.age gt 18} ? 你老了 : 你很年轻">18岁</td>
<td th:text="${#dates.format(user.birthday, 'yyyy-MM-dd hh:mm:ss')}"></td>
</tr>
</table>
<br/>
<br/>
<div th:switch="${user.name}">
<p th:case="'lee'">lee</p>
<p th:case="#{roles.manager}">普通管理员</p>
<p th:case="#{roles.superadmin}">超级管理员</p>
<p th:case="*">其他用户</p>
</div>
<br/>
</body>
</html>
四步:controller中
package cn.itcast.springboot.controller;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import cn.itcast.springboot.pojo.User;
@Controller
@RequestMapping("th")
public class ThymeleafController {
@RequestMapping("/index")
public String index(ModelMap map) {
map.addAttribute("name", "thymeleaf-imooc");
return "thymeleaf/index";
}
@RequestMapping("center")
public String center() {
return "thymeleaf/center/center";
}
@RequestMapping("test")
public String test(ModelMap map) {
User u = new User();
u.setName("superadmin");
u.setAge(10);
u.setPassword("123465");
u.setBirthday(new Date());
u.setDesc("<font color='green'><b>hello imooc</b></font>");
map.addAttribute("user", u);
User u1 = new User();
u1.setAge(19);
u1.setName("imooc");
u1.setPassword("123456");
u1.setBirthday(new Date());
User u2 = new User();
u2.setAge(17);
u2.setName("LeeCX");
u2.setPassword("123456");
u2.setBirthday(new Date());
List<User> userList = new ArrayList<>();
userList.add(u);
userList.add(u1);
userList.add(u2);
map.addAttribute("userList", userList);
return "thymeleaf/test";
}
@PostMapping("postform")
public String postform(User u) {
System.out.println("姓名：" + u.getName());
System.out.println("年龄：" + u.getAge());
return "redirect:/th/test";
}
@RequestMapping("showerror")
public String showerror(User u) {
int a = 1 / 0;
return "redirect:/th/test";
}
}
细节用法可参考项目注释.
