How to transfer parameters in th:href in spring boot Thymeleaf? - spring

Question

These are my simple Thymeleaf table HTML file and Spring MVC controller codes. First below is my table image.
I try to make some html codes to transfer the post id value to view codes when the 'Edit' or 'Delete' link are clicked, but I have no idea how to do. These are my Spring MVC Controller codes and view.html codes.
#Controller
public class PostController {
#Autowired
private PostService postService;
#RequestMapping("/posts/view/{id}")
public String view(#PathVariable("id") Long id, Model model) {
Post post = postService.findById(id);
model.addAttribute("post", post);
return "posts/view";
}
And,
<table id="blogTable" border="1" width ="1000" height="400" align = "center">
<thead>
<tr>
<th>Post ID</th>
<th>Post Title</th>
<th>Post Content</th>
<th>Date</th>
<th>Author</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<tr th:each="post : ${posts}">
<td th:text="${post.id}">Post ID</td>
<td th:text="${post.title}">Post Title</td>
<td th:text="${post.body}">Post Content</td>
<td th:text="${post.date}">Date</td>
<!-- <td th:text="${post.auther.userName()}">Author</td> -->
<td>
Edit<br/> ==> How to transfer the post.id parameter to th:href?
Delete ==> How to transfer the post.id parameter to th:href?
</td>
</tr>
</tbody>
</table>
I am a beginner in HTML and Spring. How can I put post.id value into view mvc controller through th:href tag?

Answer 1

Use th:href like described in the documentation
th:href is an attribute modifier attribute: once processed, it will compute the link URL to be used and set the href attribute of the tag to this URL.
We are allowed to use expressions for URL parameters (as you can see in orderId=${o.id}). The required URL-encoding operations will also be automatically performed.
If several parameters are needed, these will be separated by commas like #{/order/process(execId=${execId},execType='FAST')}
Variable templates are also allowed in URL paths, like #{/order/{orderId}/details(orderId=${orderId})}
For example (notice the th:href and the parameter postId that receives the value from your variable post):
<td>

</td>

Answer 2

You can add parameters in parentheses:
<a th:href="#{/index(param1='value1',param2='value2')}">
Thymeleaf evaluates the above to:
<a href="/index?param1=value1,m2=value2">
For example, suppose we set default value to two parameters; name="Dracula" and age = 25.
<a th:href=#{/person(name=${name},age=${age})}></a>

Answer 3

I used in this format and work fine.
<a th:href="#{${urlBase} + '/#!/pedido' + ${other.value}" target="_blank">Link</a>

Answer 4

You can something try like following:
Edit<br/>
Delete
