java - 从 thymeleaf 中的另一个变量声明变量

Question

如何在 thymeleaf 中使用另一个变量来声明一个变量？这就是我想做的:

<div th:with="var1='blablabla'">
    <div th:with="var2=${${var1} == null ? '' : 's'}">
       <span th:utext="${tmpCustomerType}">show var2</span>      
    </div>
</div>

但是编译器不喜欢这样${var1}:

EL1041E:(pos 1): After parsing a valid expression, there is still more data in the expression: 'lcurly({)'
(org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "${ccc} == null ? '' : ${ccc}" (custom:24))

Answer 1

你的el表达很糟糕。也许是这些。

<div th:with="var1='blablabla'">
    <div th:with="var2=var1 == null? '' : 's'">
       <span th:utext="${tmpCustomerType}">show var2</span>      
    </div>
</div>
