本文介绍了解决Thymeleaf在渲染checkbox时无法正确设置value值的方案，特别是针对Spring Command对象中数组类型的字段。通过阅读THYMELEAF官方文档，尤其是关于多值复选框的部分，找到了正确的绑定方式。

There is a section which explains multi valued check boxes.

<input type="checkbox" 
     class="ads_Checkbox" 
     th:text="${q.questionName}" 
     th:value="${q.id}" name="id"/>

In the above code we are not binding the value to the field of the command object. Instead try doing this

<input type="checkbox" 
     class="ads_Checkbox" 
     th:text="${q.questionName}" 
     th:field="*{selectedQuestions}" 
     th:value="${q.id}" />

here the selectedQuestions is an array object present in the spring command object.

I have used JSTL with JSP and thymeleaf was something new. I read the THYMELEAFdocumentation.
