springboot的thymeleaf与Freemarker模板语法
博客目录
- 1、thymeleaf模板
- 2、Freemarker模板
此项目目录结构如下：
1、thymeleaf模板
thymeleaf:：它就是html页面
导入相关的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.yml文件中加入下面这行
项目正式环境还是要将缓存开启的
application.yml文件的默认配置
spring:
thymeleaf:
cache: false
对应的后台代码
User
package com.wyy.springboot02.entity;
import lombok.Data;
/**
* @author 秃头集团王某
* @company 秃头公司
* @create 2019-11-09 10:58
*/
@Data
public class User {
private String uid;
private String uname;
public User(String uid, String uname) {
this.uid = uid;
this.uname = uname;
}
public User() {
}
}
ThymeleafController
package com.wyy.springboot02.Controller;
import com.wyy.springboot02.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 秃头集团王某
* @company 秃头公司
* @create 2019-11-09 11:07
*/
@Controller
@RequestMapping("/thymeleaf")
public class ThymeleafController {
@RequestMapping("/list")
public ModelAndView list(){
ModelAndView mv= new ModelAndView();
List list = new ArrayList();
list.add(new User("1","zs"));
list.add(new User("2","ls"));
list.add(new User("3","ww"));
mv.addObject("userList",list);
mv.addObject("msg","这个是html标签");
mv.addObject("name","ls");
//跳页面
mv.setViewName("list");
return mv;
}
}
list.html
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Thymeleaf</title>
</head>
<body>
Thymeleaf知识点详解
<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>用户的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>
<h2>包含页面</h2>
<div th:include="role/common/head2 ::h3"></div>
</body>
</html>
head2
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<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">

2、Freemarker模板
导入pom依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<!--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
src/main/resources
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/**
Role
package com.wyy.springboot02.entity;
import lombok.Data;
/**
* @author 秃头集团王某
* @company 秃头公司
* @create 2019-11-09 10:58
*/
@Data
public class Role {
private String rid;
private String rname;
public Role() {
}
public Role(String rid, String rname) {
this.rid = rid;
this.rname = rname;
}
}
FreemarkerController
package com.wyy.springboot02.Controller;
import com.wyy.springboot02.entity.Role;
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 秃头集团王某
* @company 秃头公司
* @create 2019-11-09 10:57
*/
@Controller
@RequestMapping("/freemarker")
public class FreemarkerController {
@RequestMapping("/list")
public ModelAndView list(){
ModelAndView mv = new ModelAndView();
mv.addObject("loginName","双11");
List list = new ArrayList();
list.add(new Role("1","1号用户"));
list.add(new Role("2","2号用户"));
list.add(new Role("3","3号用户"));
mv.addObject("roleList",list);
mv.setViewName("list");
return mv;
}
}
list.ftl
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Freemarker</title>
</head>
<body>
Freemarker
<h2>获取值</h2>
${loginName!'未知'}
<h2>遍历</h2>
<table border="1px" width="60%">
<tr>
<td>角色id</td>
<td>角色名</td>
</tr>
<#list roleList as role>
<tr>
<td>${role.rid}</td>
<td>${role.rname}</td>
</tr>
</#list>
</table>
<h2>包含页面</h2>
<#include 'common/head.ftl' />
<#include 'common/global.ftl' />
<h2>获取项目名</h2>
${springMacroRequestContext.contextPath}
${ctx}
<h2>如何在页面定义变量</h2>
<#assign ctx1>
${springMacroRequestContext.contextPath}
</#assign>
${ctx1}
</body>
</html>
head.ftl
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
头部页面
</body>
</html>
global.ftl
<#global ctx>
${springMacroRequestContext.contextPath}
</#global>
