简单介绍

目前在javaee领域有几中比较常用的模板引擎,分别是jsp、velocity、freemarker、thymeleaf,对freemark语法不是特别熟悉,不过对于前端页面渲染效率来说,jsp其实还是最快的,velocity次之。thymeleaf虽然渲染效率不是很快,但是语法方面是比较轻巧的,thymeleaf语法比velocity轻巧,但是渲染效率不如velocity

thymeleaf 支持html5标准;是一种模板引擎框架(templateengine framework);thymeleaf 页面无须部署到servlet开发到服务器上,直接通过浏览器就能打开。它可以完全替代 jsp 。

特点:

1.thymeleaf 在有网络和无网络的环境下皆可运行,即它可以让美工在浏览器查看页面的静态效果,也可以让程序员在服务器查看带数据的动态页面效果。这是由于它支持 html 原型,然后在 html 标签里增加额外的属性来达到模板+数据的展示方式。浏览器解释 html 时会忽略未定义的标签属性,所以 thymeleaf 的模板可以静态地运行;当有数据返回到页面时,thymeleaf 标签会动态地替换掉静态内容,使页面动态显示。

2.它提供标准和spring标准两种方言,可以直接套用模板实现jstl、 ognl表达式效果。

3.thymeleaf 提供spring标准方言和一个与 springmvc 完美集成的可选模块,可以快速的实现表单绑定、属性编辑器、国际化等功能。

maven配置

因为引入了springboot的parent工程,所以不需要写版本号

<!-- themeleaf -->
 <dependency>
  <groupid>org.springframework.boot</groupid>
  <artifactid>spring-boot-starter-thymeleaf</artifactid>
 </dependency>

application.yml配置

#添加thymeleaf配置
 thymeleaf:
 cache: false
 prefix: classpath:/templates/
 suffix: .html
 mode: html5
 encoding: utf-8
 content-type: text/html

application.yml:

server:
 port: 8081
#logging:
# config: classpath:logback_spring.xml.bat
# level:
# com.muses.taoshop: debug
# path: /data/logs

spring:

  username: root
  password: root

 driver-class-name: com.mysql.jdbc.driver

 # 连接池设置
 druid:
  initial-size: 5
  min-idle: 5
  max-active: 20
  # 配置获取连接等待超时的时间
  max-wait: 60000
  # 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒
  time-between-eviction-runs-millis: 60000
  # 配置一个连接在池中最小生存的时间,单位是毫秒
  min-evictable-idle-time-millis: 300000
  # oracle请使用select 1 from dual
  validation-query: select 'x'
  test-while-idle: true
  test-on-borrow: false
  test-on-return: false
  # 打开pscache,并且指定每个连接上pscache的大小
  pool-prepared-statements: true
  max-pool-prepared-statement-per-connection-size: 20
  # 配置监控统计拦截的filters,去掉后监控界面sql无法统计,'wall'用于防火墙
  filters: stat,wall,slf4j
  # 通过connectproperties属性来打开mergesql功能;慢sql记录
  connection-properties: druid.stat.mergesql=true;druid.stat.slowsqlmillis=5000
  # 合并多个druiddatasource的监控数据
  use-global-data-source-stat: true

# jpa:
# database: mysql
# hibernate:
#  show_sql: true
#  format_sql: true
#  ddl-auto: none
#  naming:
#  physical-strategy: org.hibernate.boot.entity.naming.physicalnamingstrategystandardimpl

# mvc:
# view:
#  prefix: /web-inf/jsp/
#  suffix: .jsp

 #添加thymeleaf配置
 thymeleaf:
 cache: false
 prefix: classpath:/templates/
 suffix: .html
 mode: html5
 encoding: utf-8
 content-type: text/html

 #jedis配置
# jedis :
# pool :
#  host : 127.0.0.1
#  port : 6379
#  password : redispassword
#  timeout : 0
#  config :
#  maxtotal : 100
#  maxidle : 10
#  maxwaitmillis : 100000

添加html文件

在resources资源文件夹下面新建一个templates文件夹,所有的html文件都丢在这里,静态资源文件也丢在resources资源文件夹下面

新建一个html文件,然后注意加上<html xmlns:th="http://www.thymeleaf.org">

注意thymeleaf语法要求比较严格 <meta charset="utf-8" > ,不如这样写是不可以的,必须加上斜杠的, <meta charset="utf-8" />

遍历后台数据

引入文件

thymeleaf引入另外一个html文件可以使用th:replace或者th:include,

<!--topbar-->
 <div class="topbar" th:replace="/top_bar :: .topbar"></div>
 <!--//topbar-->
 <!--headermain-->
 <div class="headermain layout clearfix" th:replace="/header_main :: .headermain"></div>
 <!--//headermain-->
 <!--headernav-->
 
 <div class="headernav" th:replace="/index_header_nav :: .headernav"></div>
 <!--//headernav-->

img便签src

 <img th:src="@{/static/images/rachange_ad.jpg}" />

链接<a>便签

静态资源使用

<link th:href="@{/static/css/public.css}" rel="external nofollow" rel="external nofollow" rel="stylesheet" type="text/css" />
 <link th:href="@{/static/css/index.css}" rel="external nofollow" rel="external nofollow" rel="stylesheet" type="text/css" />
 <script type="text/javascript" th:src="@{/static/js/jquery-1.3.2.min.js}"></script>
 <script type="text/javascript" th:src="@{/static/js/html5.js}"></script>
 <script type="text/javascript" th:src="@{/static/js/popbox.js}"></script>

给出一个html页面例子:
