我是新来的春天，一直在线以及几个教程。我创建了一个包含使用用户名和密码登录的应用程序。现在一切都开始正常工作，但由于我一直在应用程序上工作，它已开始登录失败，给出一个空指针的问题，但没有给出任何具体细节。这在开始时发生过一次或两次，但现在越来越严重，现在需要重新启动应用程序7或8次才能让我登录。该应用程序启动正常，但一旦我输入用户名和密码它崩溃了。春季开机登录失败
我正在使用h2数据库进行测试，这些数据用于测试用户和数据。如果有人能够帮助解决这个问题，或者指引我朝着正确的方向发展，那就太好了。以下是我的文件和Stacktrace。如果还有其他文件，您认为我应该添加以帮助获得答案留下评论，我会添加它们。
我的属性文件。
spring.h2.console.enabled=true
spring.h2.console.path=/console
spring.datasource.platform=h2
我的IndexController
@Controller
public class IndexController {
@RequestMapping("/")
public String index() {
return "/index";
}
@RequestMapping("/access_denied")
public String notAuth() {
return "access_denied";
}
@RequestMapping("/login")
public String loginForm() {
return "login";
}
@RequestMapping("/logout")
public String logout() {
return "login";
}
}
我WebSecurity配置
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private AuthenticationProvider authenticationProvider;
@Autowired
@Qualifier("daoAuthenticationProvider")
public void setAuthenticationProvider(AuthenticationProvider authenticationProvider) {
this.authenticationProvider = authenticationProvider;
}
@Bean
public PasswordEncoder passwordEncoder(StrongPasswordEncryptor passwordEncryptor) {
PasswordEncoder passwordEncoder = new PasswordEncoder();
passwordEncoder.setPasswordEncryptor(passwordEncryptor);
return passwordEncoder;
}
@Bean
public DaoAuthenticationProvider daoAuthenticationProvider(PasswordEncoder passwordEncoder,
UserDetailsService userDetailsService) {
DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
daoAuthenticationProvider.setPasswordEncoder(passwordEncoder);
daoAuthenticationProvider.setUserDetailsService(userDetailsService);
return daoAuthenticationProvider;
}
@Autowired
public void configureAuthManager(AuthenticationManagerBuilder authenticationManagerBuilder) {
authenticationManagerBuilder.authenticationProvider(authenticationProvider);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable().headers().disable()
.authorizeRequests().antMatchers("/", "/index", "/**/favicon.ico") .permitAll()
.and().authorizeRequests().antMatchers("/css/**", "/js/**", "/images/**").permitAll()
.and().formLogin().loginPage("/login").permitAll()
.and().authorizeRequests().antMatchers("/companies/**")
.hasRole("ADMIN")
.and().authorizeRequests().antMatchers("/expenses/new", "/expenses/edit/**", "expenses/save")
.hasAnyRole("ADMIN, MANAGER")
.and().authorizeRequests().antMatchers("/expenses/list", "/expenses/**")
.hasAnyRole("ADMIN, MANAGER, WORKER")
.anyRequest().authenticated()
.and().logout()
.permitAll()
.and().exceptionHandling().accessDeniedPage("/access_denied");
}
}
这是UserDetailsImpl
public class UserDetailsImpl implements UserDetails {
private Collection<SimpleGrantedAuthority> authorities;
private Integer id;
private String username;
private String password;
private Boolean enabled = true;
public void setAuthorities(Collection<SimpleGrantedAuthority> authorities) {
this.authorities = authorities;
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return authorities;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String getPassword() {
return password;
}
public void setUsername(String username) {
this.username = username;
}
@Override
public String getUsername() {
return username;
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
public void setEnabled(Boolean enabled) {
this.enabled = enabled;
}
@Override
public boolean isEnabled() {
return enabled;
}
}
SpringUserDetialsImpl其使用转换器在结合用户类
@Service("userDetailsService")
public class SpringUserDetailsImpl implements UserDetailsService {
private UserService userService;
private Converter<User, UserDetails> userUserDetailsConverter;
private static final Logger logger = LoggerFactory.getLogger(SpringUserDetailsImpl.class);
@Autowired
public void setUserService(UserService userService) {
this.userService = userService;
}
@Autowired
@Qualifier(value = "userToUserDetails")
public void setUserUserDetailsConverter(Converter<User, UserDetails> userUserDetailsConverter) {
this.userUserDetailsConverter = userUserDetailsConverter;
}
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
logger.info(String.format("User %s was found", userService.findByUsername(username).getUsername()));
return userUserDetailsConverter.convert(userService.findByUsername(username));
}
}
和转换器类
@Component
public class UserToUserDetails implements Converter<User, UserDetails> {
private static final Logger logger = LoggerFactory.getLogger(UserToUserDetails.class);
@Override
public UserDetails convert(User user) {
UserDetailsImpl userDetails = new UserDetailsImpl();
if (user != null) {
userDetails.setId(user.getId());
userDetails.setUsername(user.getUsername());
userDetails.setPassword(user.getEncryptedPassword());
userDetails.setEnabled(user.getValid());
Collection<SimpleGrantedAuthority> authorities = new ArrayList<>();
user.getRoles().forEach(role -> authorities.add(new SimpleGrantedAuthority(role.getRole())));
userDetails.setAuthorities(authorities);
logger.info(String.format("User details %s", userDetails.getUsername()));
return userDetails;
} else {
System.out.print("This is an issue");
return userDetails;
}
}
}
而且堆栈跟踪

请出示您的UserDetailsService或在github上发布，也许整个应用程序？ –
变化（自动装配）为'@Autowired私人的AuthenticationProvider的AuthenticationProvider;' –
@PrasannaKumar你是对的添加“@Autowired”到的AuthenticationProvider的AuthenticationProvider变量一些奇怪的原因似乎是工作。我想用Spring正确的协议是要么使用依赖二传手或者构造。如果你想给一个完整的答案和一些解释，我可以将其标记为正确的。 –
