英文:
Thymeleaf - output variable without a tag
问题
我使用Thymeleaf作为模板引擎，通常像这样输出变量值：
在Java中，我设置：
ctx.setVariable("tester", "hello");
然后在HTML模板中，我输出：
<span th:text="${tester}"></span>
这个方法效果很好，但我想在不需要标签的情况下输出一个变量。像下面这样的方式会很好：
${tester}
不幸的是，这并不起作用。我的目标是避免使用不必要的标签来输出变量值。在Thymeleaf中能实现这一点吗？
英文:
I use Thymeleaf as a templating engine and I usually output variable value like this:
in Java I set:
ctx.setVariable("tester", "hello");
and in html template I output:
<span th:text="${tester}"></span>
This works great, but I would like to output a variable without the need of a tag. Something following would be great:
${tester}
Unfortunately it does not work. My goal is to avoid unnecessary tag to output the variable value. Is this possible to do with Thymeleaf?

My goal is to avoid unnecessary tag to output the variable value. Is this possible to do with Thymeleaf?
Yes this is possible. You can use the Thymeleaf synthetic th:block tag (see here).
Example template excerpt:
<body>
<th:block th:text="${tester}"></th:block>
</body>
This renders the following HTML:
<body>
hello
</body>
Only the variable is displayed.

使用Thymeleaf表达式内联（文档）可以使用[[...]]或[(...)]。通过表达式内联，您无需使用合成标签。
示例：
<body>
tester的值为[[${tester}]]。
</body>
英文:
Use Thymeleaf expression inlining (docs) using either [[...]] or [(...)]. With expression inlining, you do not need to use synthetic tags.
Example:
<body>
The value of tester is [[${tester}]].
</body>

Thymeleaf触发在"th:"标签上，据我所知，这是唯一的方式。
您描述的行为适用于JSF。
最好的问候

英文:
Thymeleaf triggers on the "th:" tag and as far as I know thats the only way.
The behaviour you describe works with JSF.

我还找到了一些解决方法：
<span th:text="${tester}" th:remove="tag"></span>
th:remove 移除了 span 标签，但保留内容。
英文:
I also managed to figure out some workaround:
<span th:text="${tester}" th:remove="tag"></span>
th:remove removes span tag, but preserves content.
