Passing tokens through microservices using oauth2 authentication through GitHub

For this assignment we are to implement oauth2 using OAuth Apps in GitHub. We have two microservices UMS (UserManagmentService) and Messaging service. I am following the tutorial https://spring.io/guides/tutorials/spring-boot-oauth2/, as recommended - and it is working fine. I now have to extract the token and save it to a database with an expiry of 15 minutes in order to pass it to the other microservice (? I believe there is better ways to implement this). I would rather use JWT but do not understand the process to do so after using oauth2 through GitHub. My main questions are:
How to extract the token and store it to a database
How to set an expiry to the token
If possible, how to use a JWT instead and do the above.
I have limited knowledge of this as it is a new concept, any help would be appreciated.

How to predict data in an input field with spring boot as user type?

Can anyone please help me out on this issue?
I would like to predict words from a database into an input field using spring boot. Example if I type « I am searching for a book called snowfall » in the input field, the title snowfall should be predicted in this field when the user starts to type the word if it exists in the database.
Many thanks in advance for your answers.

if im following your requirement , when the UI user inserts for example "a" you would like to show a list of all books starting (or containing a), this is called a LIKE query - using the #Query annotation you are already using in your repo you should do this (this will return everything that contains 'a'):
#Query("SELECT b FROM books b WHERE b.bookName LIKE %:title%")
List<Book> searchByTitleLike(#Param("title") String title);
for everything starting with 'a':
#Query("SELECT b FROM books b WHERE b.bookName LIKE :title%")
List<Book> searchByTitleLike(#Param("title") String title);
this is an altered example taken from this article: https://www.baeldung.com/spring-jpa-like-queries

When you upgrade your security version 5 and it will be fixed.

Try changing this
<li sec:authorize="isAnonymous()"><a th:href="#{/login}">MY ACCOUNT</a></li>
For this
<li sec:authorize="!isAuthenticated()"><a th:href="#{/login}">MY ACCOUNT</a></li>

Controller class cannot find html template

My directory
I'm trying to create spring boot application for school that lists books to a html page from database with a controller.
Personally, i think that the problem is that the controller cannot find the template for some reason. Because when i navigate to the wanted template through chrome, it just shows "booklist" on the page, nothing else.
I've tried creating totally new project and copying the code from my other files to the new files with no results.
My controller class:
#Controller
#ResponseBody
public class BookController {
#Autowired
BookRepository bookRepository;
#RequestMapping(value = "/books", method = RequestMethod.GET)
public String getBooks(Model model) {
List<Book> books = (List<Book>) bookRepository.findAll();
model.addAttribute("books", books);
return "booklist";
}
My html template:
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Book List</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<h1>Books</h1>
<table>
<tr>
<th>Id</th>
<th>Title</th>
<th>Year</th>
<th>Isbn</th>
<th>Price</th>
</tr>
<tr th:each="book : ${books}">
<td th:text="${book.id}">id</td>
<td th:text="${book.title}">title</td>
<td th:text="${book.year}">year</td>
<td th:text="${book.isbn}">isbn</td>
<td th:text="${book.price}">price</td>
</tr>
</table>

Remove the annotation #ResponseBody from your controller class, because:
The #ResponseBody annotation tells a controller that the object returned is automatically serialized into JSON and passed back into the HttpResponse object.
Then the returned String booklist will be used by Spring-MVC to resolve the named HTML template file.
The template file (e.g. booklist.html) will be looked for by default within default template directory is src/main/resources/templates.
Otherwise make sure to have configured the ViewResolver properly.
For Thymeleaf you have to add dependency to your Maven POM:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
See also this Spring-Boot & Thymeleaf tutorial

You can try this .
Hit : localhost://yourportnumber/api/books
//#Controller
#RestController
//#ResponseBody
#RequestMapping("/api")
public class BookController {
#Autowired
BookRepository bookRepository;
#GetMapping(value = "/books", method = RequestMethod.GET)
public ModelAndView getBooks(Model model) {
List<Book> books = (List<Book>) bookRepository.findAll();
model.addAttribute("books", books);
ModelAndView mav = new ModelAndView("booklist");
return mav;
}
