1 怎么使用
前端html页面标签中引入如下：<html xmlns:th="http://www.thymeleaf.org">
2 表达式
- 简单表达式
- 可用值表达式(后台设置):
${…} - 所有可用值表达式:
*{…}比如*{name} 从可用值中查找name，如果有上下文，比如上层是object，则查object中的name属性。 - 消息表达式:
#{…}国际化时使用，也可以使用内置的对象，比如date格式化数据 - 链接表达式:
@{…}
用来配合link src href使用的语法 - 片段表达式:
~{…}
用来引入公共部分代码片段，并进行传值操作使用的语法。 - 文字
- 文本：
'one text', 'another text', … - 数字：
1,2,1.2，… - 布尔:
true, false - 空值：
null - 单词:
something, main, name, … - 文本操作
- 链接：
+ - 替换：
|The name is ${name}|
“`html
链接地址：
//渲染后的结果
链接地址：
* 数学操作
* 二元操作：`+, - , * , / , %`
* 一元操作: `- （负）`
* 布尔操作
* 一元 : `and, or`
* 二元 : `!, not`
* 比较
* 比较：`> , < , >= , <= ( gt , lt , ge , le )`
* 等于：`== , != ( eq , ne )`
* 条件
* If-then: `(if) ? (then)`
* If-then-else: `(if) ? (then) : (else)`
* Default: `(value) ?: (defaultvalue)`
* 无操作
* 使用`_ `来禁止转义。
