Given the following record and trying to read the accountId property in a Thymeleaf template (well actually any property will fail).

public record Account(Long accountId, String description) {}

Then in Thymeleaf trying to read the accountId with the following

<a href="#" th:text="${account.description}" th:href="@{/accounts.html(accountId=${account.accountId})}">Link to account</a>

fails with an exception

org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/accountList.html]")

I hoped that with implementing #24391 this would also transparently work for SpEL expression, which apparently isn't the case.

Current workaround

<a href="#" th:text="${account.description()}" th:href="@{/accounts.html(accountId=${account.accountId()})}">Link to account</a>

Changing the template to use the the accountId() method instead of the property makes it work. Nonetheless, it would be nice if this would just work(TM).

Changing the template to use the the accountId() method instead of the property makes it work.

That's because accountId() is a method invocation rather than "property access", and SpEL's property access support only works for JavaBean style getter methods.

@aclement and @jhoeller, what do you think about relaxing the property access support to allow it to treat any accessor method as a "property"?

I admit I forgot to consider SpEL there. This is indeed a valid argument, if our BeanWrapper infrastructure leniently handles such plain accessor methods, SpEL should do so too. I'll try to close that gap for 5.3.1.
