问题描述

我在教程中找不到这两个说明之间的区别.

I can't find on the tutorial the difference between this two instructions.

th:field="${something}" 和 th:field="*{something}"

谁能给我举个例子?

推荐答案

参考站点

五种类型:

• ${...} :变量表达式.这些是 OGNL 表达式(或 SpringEL 如果你有 spring 集成)

• ${...} : Variable expressions. These are OGNL expressions (or Spring EL if you have spring integrated)

*{...} :选择表达式.同上，除了它只会在之前选择的对象上执行

*{...} : Selection expressions. Same as above, excepted it will be executed on a previously selected object only

#{...} :消息 (i18n) 表达式.用于从外部来源检索特定于语言环境的消息

#{...} : Message (i18n) expressions. Used to retrieve locale-specific messages from external sources
