The first 一method: use the expansion pack to obtain user information
Instructions
1. First introduce the extension dependencies of Thymeleaf and SpringSecurity:
My SpringBoot version is 2.2.6.RELEASEthe default version of SpringSecurity, 5.2.2.RELEASE
so I chose the 5 version of the extension dependency package
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>
You can also choose the 4 extension dependency package according to your own situation: thymeleaf-extras-springsecurity4
2. Then introduce relevant constraints on the Thymeleaf page:
<html lang="en" xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity5"><!-- Thymeleaf提供的Spring Security标签支持 -->
3. Use
登录名：<span sec:authentication="name"></span>
角色：<span sec:authentication="principal.authorities"></span>
用户名：<span sec:authentication="principal.username"></span>
密码：<span sec:authentication="principal.password"></span>
Of course there are other ways (whispering bb
The first 二method: use Session to obtain user information
Because I used to think that Spring Security directly jumped to the success page without a custom method. It is impossible to obtain user information in the method,
and then suddenly remembered that since I was calling the method in the Service to query the user, it should be available in the Service class. Save the user information in the session, and then get the information in the session on the page
Code:
@Service
public class UserServiceImpl implements UserService{
@Autowired
private UserRepository userRepository;
@Autowired
HttpSession session;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userRepository.findByUsername(username);
if (user!=null)
{
session.setAttribute("USER_INFO",user);
...(省略)
}
...(省略)
}
}
Get at the front desk:
用户名：<span th:text="${session.USER_INFO.username}"></span>
