thymeleaf引擎使用

原理

 

public static final String DEFAULT_PREFIX = "classpath:/templates/";

    public static final String DEFAULT_SUFFIX = ".html";

controller层会在classpath:/templates/下找到一.html结尾的html页面，controller返回的页面会自动拼接页面

 

 

1.导入依赖

<!--Thymeleaf-->
<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf-spring5</artifactId>
</dependency>
<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-java8time</artifactId>
</dependency>

2.使用参考文档Tutorial: Using Thymeleaf

参考

Simple expressions:
Variable Expressions: ${...}
Selection Variable Expressions: *{...}
Message Expressions: #{...}
Link URL Expressions: @{...}
Fragment Expressions: ~{...}
Literals
Text literals: 'one text' , 'Another one!' ,…
Number literals: 0 , 34 , 3.0 , 12.3 ,…
Boolean literals: true , false
Null literal: null
Literal tokens: one , sometext , main ,…
Text operations:
String concatenation: +
Literal substitutions: |The name is ${name}|
Arithmetic operations:
Binary operators: + , - , * , / , %
Minus sign (unary operator): -
Boolean operations:
Binary operators: and , or
Boolean negation (unary operator): ! , not
Comparisons and equality:
Comparators: > , < , >= , <= ( gt , lt , ge , le )
Equality operators: == , != ( eq , ne )
Conditional operators:
If-then: (if) ? (then)
If-then-else: (if) ? (then) : (else)
Default: (value) ?: (defaultvalue)

 

　　1.导入头文件xmlns:th="http://www.thymeleaf.org"

　　2.controller层存数据

　　

    @RequestMapping("/test")
    public String test(Model model){
        model.addAttribute("wang","王深圳");
        return "test";
    }

　　3.test.html取数据

　　

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>test</h1>
<h2 th:text="${wang}"></h2>
</body>
</html>

所有的html元素都可以被thymeleaf替换接管:th:元素名

遍历元素

<ul>
    <li th:text="${item}" th:each="item:${array}"></li>
</ul>
