SpringBoot模板引擎
关于Thymeleaf的优点，我只说一条：它就是html页面。下面直接上代码
相关pom依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
Spring Boot官方文档建议在开发时将缓存关闭，那就在application.properties文件中加入下面这行
spring.thymeleaf.cache=false
然后下面是我的application.properties文件中关于这个案例的所有代码：
server:
port: 80
servlet:
context-path: /
spring:
thymeleaf:
cache: false
对应的后台代码：
package com.lihao.springboot01.entity;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
/**
* @author 浩梦溪
* @site www.lihao.com
* @company xxx公司
* @create 2019-11-07 16:58
*/
@ConfigurationProperties(
prefix = "user"
)
@Component
@Data
public class User {
private String uid;
private String uname;
public User(){
}
public User(String uid,String uname){
this.uid = uid;
this.uname = uname;
}
}
ThymeleafController ：
package com.lihao.springboot01.controller;
import com.lihao.springboot01.entity.User;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.List;
/**
* @author 浩梦溪
* @site www.lihao.com
* @company xxx公司
* @create 2019-11-08 18:38
*/
@Controller
@RequestMapping("/thymeleaf")
public class ThymeleafController {
@RequestMapping("/list")
public ModelAndView list(){
ModelAndView mv = new ModelAndView();
List list = new ArrayList();
list.add(new User("1","xs"));
list.add(new User("2","lh"));
list.add(new User("3","hmx"));
mv.addObject("userList",list);
mv.addObject("msg","<span style='color:red;'>双十一</span>");
mv.addObject("name","zs");
mv.setViewName("list");
return mv;
}
// public String list2(HttpServletRequest request){
// return "list";
// }
}
下面是我的前台HTML页面：
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>thymeleaf知识点讲解页面</title>
</head>
<body>
thymeleaf知识点讲解页面
<h2>显示文本</h2>
<span th:text="${name}"></span>
<h2>显示html</h2>
<div th:utext="${msg}"></div>
<h2>循环</h2>
<table>
<tr>
<td>用户id</td>
<td>用户名</td>
</tr>
<tr th:each="u : ${userList}">
<td th:text="${u.uid}"></td>
<td th:text="${u.uname}"></td>
</tr>
</table>
<h2>包含页面</h2>
<div th:include="role/common/head2"></div>
</body>
</html>
你刚刚创建html文件的是时候是没有下面那条代码的要自己加：
<html xmlns:th="http://www.thymeleaf.org">
下面这张图片是HTML文件所在的位置：
还有一个head2.xml:
<div th:fragment="h1">
第一部分内容
</div>
<div th:fragment="h2">
第二部分内容
</div>
<div th:fragment="h3">
第三部分内容
</div>

导入pom依赖：

为了方便我就把我的pom.xml都敲进来
application.yml文件的默认配置
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/**
list.ftl：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>讲解Freemarker</title>
</head>
<body>
讲解Freemarker
<h2>获取值</h2>
${logineName!'超神的存在不在我们的范围内'}</br>
${loginName!'超神的存在不在我们的范围内'}
<h2>遍历</h2>
<table border="1" width="60%">
<tr>
<td>角色ID</td>
<td>角色名字</td>
</tr>
<#list roleList as role>
<tr>
<td>${role.rid}</td>
<td>${role.rname}</td>
</tr>
</#list>
</table>
<h2>包含页面</h2>
<#include 'common/head.ftl'/>
<h2>获取项目名</h2>
如果没有效果那就是我们没有在application.yml中定义项目名：
<#--<#assign ctx1>-->
<#-- ${springMacroRequestContext.contextPath}-->
<#--</#assign>-->
<#--${ctx1}-->
<#--${springMacroRequestContext.contextPath}-->
<#include 'common/global.ftl'/>
${ctx}
添加请求映射
