springboot之thymeleaf模板
在开发前建议把缓存关闭
在配置文件application.properties文件修改(我改为了yml文件)
spring.thymeleaf.cache=false
正式环境还是要将缓存开启的
Thymeleaf相当于html页面
相关pom依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
使用ModelAndView
模板语法
页面加入<html xmlns:th="http://www.thymeleaf.org">
controller层UserController
package com.hsl.springboot01.controller;
import com.hsl.springboot01.entity.User;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.ArrayList;
import java.util.List;
/**
* @author water
* @site www.water.com
* @company xxx公司
* @create 2019-12-28 16:45
* <p>
* thymeleaf的应用
*/
@Controller
@RequestMapping("/thymeleaf")
public class UserController {
@RequestMapping("/users1")
public String users1() {
System.out.println("且歌且行且牵挂");
return "users1";
}
@RequestMapping("/users2")
public ModelAndView users2() {
ModelAndView mv = new ModelAndView();
mv.addObject("title","用户列表");
List list=new ArrayList();
list.add(new User(1,"water1","女",19));
list.add(new User(2,"water2","女",19));
list.add(new User(3,"water3","女",19));
mv.addObject("users",list);
//html转义
mv.addObject("msg","<span style='color:red'> 优秀员工师water1</span>");
mv.setViewName("users1");
// System.out.println("隔花隔木隔慧之");
return mv;
}
}
html页面:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>thymeleaf应用</title>
</head>
<body>
<!--thymeleaf应用-->
<h1>thymeleaf语法</h1>
<!--<h3 th:text="${title}"></h3>-->
<table border="1" cellpadding="0" cellspacing="0" width="600px" style="text-align: center" align="center">
<caption th:text="${title}"></caption>
<tr>
<th>员工ID</th>
<th>员工姓名</th>
<th>员工性别</th>
<th>员工年龄</th>
</tr>
<tr th:each="u : ${users}">
<td th:text="${u.uid}"></td>
<td th:text="${u.uname}"></td>
<td th:text="${u.sex}"></td>
<td th:text="${u.age}"></td>
</tr>
</table>
<p th:utext="${msg}"></p>
</body>
</html>
thymeleaf包含公共区域的方案
创建common.html
<div th:fragment="h1">
人生似水岂无涯
</div>
<div th:fragment="h2">
浮云吹作雪
</div>
<div th:fragment="h3">
世味煮成茶
</div>
页面添加代码:
<!--thymeleaf包含公共区域的方案-->
包整体
<div th:include="common.html"></div>
<hr>
包三部分
<div th:replace="common::h3"></div>
<hr>
包二三部分
<div th:replace="common::h1"></div>
<div th:replace="common::h3"></div>
springboot之freemarker模板
配置ftl文件
一开始我们新建freemarker.ftl文件师是找不到的
需要在setting配置一下
当然我们也可以不配置,只要创建html5文件,把后缀名改成ftl就可以了
应用
导入pom依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
编译可能需要的代码,可以不加
<!--可以不加,但是做项目的时候可能会用-->
<resources>
<!--解决mybatis-generator-maven-plugin运行时没有将XxxMapper.xml文件放入target文件夹的问题-->
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
<!--freemarker模板也读取需要注释标红地方-->
<resource>
<directory>src/main/resources</directory>
<includes>
<!--<include>*.properties</include>-->
<!--<include>*.xml</include>-->
<!--<include>*.yml</include>-->
</includes>
</resource>
</resources>
yml文件配置
server:
port: 80
servlet:
context-path: /
spring:
thymeleaf:
cache: false
freemarker:
# 设置模板后缀名
suffix: .ftl
# 设置文档类型
content-type: text/html
# 设置页面编码格式
charset: UTF-8
# 设置页面缓存
cache: false
# 设置ftl文件路径,默认是/templates,为演示效果添加role
template-loader-path: classpath:/templates/role
mvc:
static-path-pattern: /static/**
创建ftl文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>freemarker应用</title>

<body>
<h2>取值</h2>
<h3>提供默认值</h3>
