Intro to Spring Boot: Views (Part 2)

Notes

Keep building functionality into your CheeseMVC application by coding along with the video. We'll cover some new Thymeleaf syntax including the following:

For Loops

Example of creating an unordered list from model data:

<ul>
    <li th:each="cheese : ${cheeses}" th:text="${cheese}"></li>
</ul>

Conditions

Example of conditionally displaying a message if there is no model data for cheeses or the size of the ArrayList is zero:

<p th:unless="${cheeses} and ${cheeses.size()}">no cheese :(</p>

To make your code more Spring-like replace these lines:

    public String processAddCheeseForm(HttpServletRequest request){
        String cheeseName = request.getParameter("cheeseName");

with this:

    public String processAddCheeseForm(@RequestParam String cheeseName){

If you want to learn more about @RequestParam, check out this tutorial and the Spring Docs.

Code

We end this lesson with the code in the video-views-pt2-end branch of the cheese-mvc repo: ending code.
