當我運行代碼時，一切看起來都很好，進入了基本的登錄頁面，我從資料庫中輸入了用戶名/密碼，但沒有任何反應
和 IntellIj 寫這個：

與資料庫的連接很好，我也可以列出用戶 感謝您閱讀所有這些，對于糟糕的英語和錯誤表示抱歉，祝您有美好的一天！
uj5u.com熱心網友回復：
java.lang.StackOverflowError錯誤告訴您service層中的方法宣告未與任何JpaRepository. 問題是從上來loadUserByUsername的方法userServiceimpl。您宣告方法findByUsername而不與Repository.
改變
User user = findByUsername(username);
到
User user = userRepository.findByUsername(username);
并且只UserServiceImpl執行UserDetailsService。您需要更改Security config代碼，因為它有更多問題，例如添加錯誤的注釋和兩個具有相同名稱的方法宣告等...
修改的 Security config
@EnableWebSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter{
@Autowired
private UserDetailsService userDetailsService;
@Bean
public AuthenticationProvider authProvider() {
DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
provider.setUserDetailsService(userDetailsService);
provider.setPasswordEncoder(passwordEncoder());
return provider;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.anyRequest()
.authenticated()
.and()
.formLogin()
.permitAll();
}
@Bean
public PasswordEncoder passwordEncoder()
{
return new BCryptPasswordEncoder();
}
}
uj5u.com熱心網友回復：
您已經雙重宣告了同名的 userDetailsS??ervice，
第一的：
@Bean
@Override
public UserDetailsService userDetailsService() {
return super.userDetailsService();
}
第二：
@Service("userDetailsService")
public class UserServiceImpl implements UserService, UserDetailsService {
它可能會導致問題。您應該只有一個 userDetailService 實體。
uj5u.com熱心網友回復：
在您的 SecurityConfig 中，您可以嘗試洗掉
@Autowired
private UserDetailsService userDetailsService;
@Bean
@Override
public UserDetailsService userDetailsService() {
return super.userDetailsService();
}
并改變實作
@Override
@Autowired
public void configure(AuthenticationManagerBuilder auth) throws Exception{
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
到
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception{
auth.userDetailsService(new UserServiceImpl()).passwordEncoder(passwordEncoder());
}
