Accessing HashMap values in Thymeleaf for Broadleaf e-commerce

Hey folks, I’m working on a Broadleaf e-commerce project and I’m stuck on something. I’ve got a HashMap with String keys and List values that I’m passing to a Thymeleaf template. I can see the map on the page, but I’m not sure how to get specific values using a key.

Is there a way to do something like map.get(key) in Thymeleaf? I know how to handle the data once I get it, but I’m stumped on how to fetch it in the first place.

Here’s a simplified example of what I’m trying to do:

<div th:with="offerList=${myMap.get('someKey')}">
    <!-- Process offerList here -->
</div>

But that doesn’t work. Any ideas on how to make this happen in Thymeleaf? Thanks in advance for your help!

I’ve encountered this issue before when working with Broadleaf. The square bracket notation is indeed the correct approach for accessing HashMap values in Thymeleaf. Here’s what you can do:

This syntax should retrieve the List associated with ‘someKey’. If you need to access multiple keys, you might want to consider using th:each to iterate over the map entries. It’s more efficient and allows for dynamic key handling:

Remember to handle potential null values to avoid template rendering errors. Let me know if you need any clarification on implementing these solutions.

Yo MeditatingPanda, I’ve dealt with similar stuff. Try using brackets like this:

This should grab the List for that key. lmk if it works for ya!

Hey there, MeditatingPanda! :panda_face:

Ooh, Thymeleaf and HashMaps can be tricky sometimes, can’t they? I’ve been there too! Have you tried using square bracket notation instead of the dot notation? Something like this might work:

<div th:with="offerList=${myMap['someKey']}">
    <!-- Your offer processing magic here -->
</div>

I’m super curious - what kind of offers are you working with? Is it for a specific product category or something site-wide?

Also, just wondering, have you considered using Thymeleaf’s iteration capabilities to loop through your HashMap entries? It might give you more flexibility if you need to display multiple offer lists.

Let me know if that helps or if you need more ideas. Always excited to chat about e-commerce solutions! :blush:
