Thymeleaf基本知识
Thymeleaf是个XML/XHTML/HTML5模板引擎，能够用于Web与非Web应用。css
Thymeleaf的主要目标在于提供一种可被浏览器正确显示的、格式良好的模板建立方式，所以也能够用做静态建模。你能够使用它建立通过验证的 XML与HTML模板。相对于编写逻辑或代码，开发者只需将标签属性添加到模板中便可。接下来，这些标签属性就会在DOM（文档对象模型）上执行预先制定 好的逻辑。Thymeleaf的可扩展性也很是棒。你能够使用它定义本身的模板属性集合，这样就能够计算自定义表达式并使用自定义逻辑。这意味着 Thymeleaf还能够做为模板引擎框架。html
Thymeleaf的模板还能够用做工做原型，Thymeleaf会在运行期替换掉静态值。例以下面的html文件，看成为静态文件 时，product name显示为Red Chair，当运行在容器中并提供product这个对象时，product name的值会自动替换为product.description对应的值。java
1.bean值替换
1 <!DOCTYPE html> 2 <html xmlns:th="http://www.thymeleaf.org"> 3 <head> 4 <title>Thymeleaf tutorial: exercise 2</title> 5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" /> 6 <meta charset="utf-8" /> 7 </head> 8 <body> 9 <h1>Thymeleaf tutorial - Answer for exercise 1: bean values</h1> 10 <h2>Product information</h2> 11 <dl> 12 <dt>Product name</dt> 13 <dd th:text="${product.description}">Red Chair</dd> 14 15 <dt>Product price</dt> 16 <dd th:text="${product.price}">350</dd> 17 18 <dt>Product available from</dt> 19 <dd th:text="${product.availableFrom}">2014-12-01</dd> 20 </dl> 21 </body> 22 </html>
2.简单数据转换（数字，日期）
1 <!DOCTYPE html> 2 <html xmlns:th="http://www.thymeleaf.org"> 3 <head> 4 <title>Thymeleaf tutorial: exercise 2</title> 5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" /> 6 <meta charset="utf-8" /> 7 </head> 8 <body> 9 <h1>Thymeleaf tutorial - Answer for exercise 2: bean values</h1> 10 <h2>Product information</h2> 11 <dl> 12 <dt>Product name</dt> 13 <dd th:text="${product.description}">red Chair</dd> 14 15 <dt>Product price</dt> 16 <dd th:text="${#numbers.formatDecimal(product.price, 1, 2)}">180</dd> 17 18 <dt>Product available from</dt> 19 <dd th:text="${#dates.format(product.availableFrom, 'yyyy-MM-dd')}">2014-12-01</dd> 20 </dl> 21 </body> 22 </html>
3.字符串拼接
1 <!DOCTYPE html> 2 <html xmlns:th="http://www.thymeleaf.org"> 3 <head> 4 <title>Thymeleaf tutorial: exercise 3</title> 5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" /> 6 <meta charset="utf-8" /> 7 </head> 8 <body> 9 <h1>Thymeleaf tutorial - Answer for exercise 3: string concatenation</h1> 10 <h2>Product information</h2> 11 <dl> 12 <dt>Product price</dt> 13 <dd th:text="${'$'+product.price}">235</dd> 14 </dl> 15 </body> 16 </html>
4.国际化
1 <!DOCTYPE html> 2 <html xmlns:th="http://www.thymeleaf.org"> 3 <head> 4 <title th:text="#{tutorial.exercise4}">Thymeleaf tutorial: exercise 4</title> 5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" /> 6 <meta charset="utf-8" /> 7 </head> 8 <body> 9 <h1 th:text="#{tutorial.exercise4}">Thymeleaf tutorial - Solution for exercise 4: internationalization</h1> 10 <h2 th:text="#{product.info}">Product information</h2> 11 <dl> 12 <dt th:text="#{product.name}">Product name</dt> 13 <dd th:text="${product.description}">Red chair</dd> 14 15 <dt th:text="#{product.price}">Product price</dt> 16 <dd th:text="${#numbers.formatDecimal(product.price, 1, 2)}">350</dd> 17 18 <dt th:text="#{product.available}">Product available from</dt> 19 <dd th:text="${#dates.format(product.availableFrom, 'dd-MMM-yyyy')}">28-Jun-2013</dd> 20 </dl> 21 </body> 22 </html>
此时html须要相应的配置文件。例如以下配置文件：express
en：浏览器
tutorial.exercise4=Thymeleaf tutorial - exercise 4: internationalization
product.info=Product information
product.name=Product name
product.price=Product price
product.available=Product available from
back=Back
frapp
tutorial.exercise4=Tutorial De Thymeleaf - exercice 4: l'internationalisation
product.info=Information du produit
product.name=Nom du produit
product.price=Prix du produit
product.available=Produit disponible depuis
back=Revenir
5.转义和非转义文本
1 <!DOCTYPE html> 2 <html xmlns:th="http://www.thymeleaf.org"> 3 <head> 4 <title>Thymeleaf tutorial: exercise 5</title> 5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" /> 6 <meta charset="utf-8" /> 7 </head> 8 <body> 9 <h1>Thymeleaf tutorial - Solution for exercise 5: escaped and unescaped text</h1> 10 <div th:text="${html}"> 11 Some escaped text 12 </div> 13 <div th:utext="${html}"> 14 Some unescaped text 15 </div> 16 </body> 17 </html>
上述两个div分别生成的html代码为框架
<div>This is an <em>HTML</em> text. <b>Enjoy yourself!</b></div> <div>This is an <em>HTML</em> text. <b>Enjoy yourself!</b></div>
6.迭代
1 <!DOCTYPE html> 2 <html xmlns:th="http://www.thymeleaf.org"> 3 <head> 4 <title>Thymeleaf tutorial: exercise 6</title> 5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" /> 6 <meta charset="utf-8" /> 7 </head> 8 <body> 9 <h1>Thymeleaf tutorial - Answer for exercise 6: iteration</h1> 10 <h2>Product list</h2> 11 <table> 12 <thead> 13 <tr> 14 <th>Description</th> 15 <th>Price</th> 16 <th>Available from</th> 17 </tr> 18 </thead> 19 <tbody th:remove="all-but-first"> 20 <tr th:each="product:${productList}"> 21 <td th:text="${product.description}">Red Chair</td> 22 <td th:text="${'$' + #numbers.formatDecimal(product.price, 1, 2)}">$123</td> 23 <td th:text="${#dates.format(product.availableFrom, 'yyyy-MM-dd')}">2014-12-01</td> 24 </tr> 25 <tr> 26 <td>White table</td> 27 <td>$200</td> 28 <td>15-Jul-2013</td> 29 </tr> 30 <tr> 31 <td>Reb table</td> 32 <td>$200</td> 33 <td>15-Jul-2013</td> 34 </tr> 35 <tr> 36 <td>Blue table</td> 37 <td>$200</td> 38 <td>15-Jul-2013</td> 39 </tr> 40 </tbody> 41 </table> 42 </body> 43 </html>
7.迭代统计

8.条件判断
1 <!DOCTYPE html> 2 <html xmlns:th="http://www.thymeleaf.org"> 3 <head> 4 <title>Thymeleaf tutorial: exercise 8</title> 5 <link rel="stylesheet" href="../../../css/main-static.css" th:href="@{/css/main.css}" /> 6 <meta charset="utf-8" /> 7 </head> 8 <body> 9 <h1>Thymeleaf tutorial - Answer for exercise 8: conditions</h1> 10 <h2>Product list</h2> 11 <table> 12 <thead> 13 <tr> 14 <th>Description</th> 15 <th>Price</th> 16 <th>Available from</th> 17 <th></th> 18 </tr> 19 </thead> 20 <tbody> 21 <tr th:each="product : ${productList}"> 22 <td th:text="${product.description}">Red chair</td> 23 <td th:text="${'$' + #numbers.formatDecimal(product.price, 1, 2)}">$350</td> 24 <td th:text="${#dates.format(product.availableFrom, 'dd-MMM-yyyy')}">28-Jun-2013</td> 25 <td> 26 <span th:if="${product.price lt 100}" class="offer">Special offer!</span> 27 </td> 28 </tr> 29 </tbody> 30 </table> 31 </body> 32 </html>
