我一直在尝试使用UserDetailsService设置Spring Security。例如,我使用baeldung's tutorial。该应用程序已启动,无任何例外,但验证不起作用。 目前,我为每个应用程序模块提供了一个核心spring java配置和spring java配置。
Core Spring Java conf:
public class AppInitializer implements WebApplicationInitializer {
@Override
@Autowired
public void onStartup(ServletContext container) throws ServletException {
AnnotationConfigWebApplicationContext context = getContext();
container.addListener(new ContextLoaderListener(context));
container.setInitParameter("spring.profiles.active", "dev"); //Workaround for NamingException
container.setInitParameter("spring.profiles.default", "dev"); //Workaround for NamingException
container.setInitParameter("spring.liveBeansView.mbeanDomain", "dev"); //Workaround for NamingException
ServletRegistration.Dynamic mainDispatcher =
container.addServlet("dispatcher", new DispatcherServlet(context));
ServletRegistration.Dynamic businessDispatcher =
container.addServlet("businessDispatcher", BusinessAppConfig.createDispatcherServlet(context));
ServletRegistration.Dynamic ppaDispatcher =
container.addServlet("ppaDispatcher", PpaAppConfig.createDispatcherServlet(context));
initDispatcher(mainDispatcher, 1, "/");
initDispatcher(businessDispatcher, 2, "/business");
initDispatcher(businessDispatcher, 3, "/ppa");
}
private void initDispatcher(ServletRegistration.Dynamic dispatcher, int loadOnStartUp, String mapping) {
if (dispatcher == null) {
System.out.println("Servlet" + dispatcher.getName() + " is already added");
} else {
dispatcher.setLoadOnStartup(loadOnStartUp);
dispatcher.addMapping(mapping);
}
}
public AnnotationConfigWebApplicationContext getContext() {
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.register(MvcConfiguration.class);
return context;
}
@Bean(name = "propertyConfigurer")
public PropertySourcesPlaceholderConfigurer getPropertyPlaceholderConfigurer() {
PropertySourcesPlaceholderConfigurer placeholderConfigurer = new PropertySourcesPlaceholderConfigurer();
placeholderConfigurer.setLocation(new ClassPathResource("common.properties"));
placeholderConfigurer.setLocation(new ClassPathResource("amazon.S3Storage.properties"));
placeholderConfigurer.setLocation(new ClassPathResource("local.storage.properties"));
placeholderConfigurer.setLocation(new ClassPathResource("log4j.properties"));
placeholderConfigurer.setIgnoreUnresolvablePlaceholders(true);
return placeholderConfigurer;
}
}
用于业务模块的Spring java conf
@Configuration
public class BusinessAppConfig {
public static Servlet createDispatcherServlet(AnnotationConfigWebApplicationContext context) {
context.register(BusinessMvcConfig.class);
context.register(BusinessHibernateConfig.class);
context.register(BusinessSecurityConfig.class);
return new DispatcherServlet(context);
}
}
Spring Security java conf for a business module
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class BusinessSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authenticationProvider());
}
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Autowired
public DaoAuthenticationProvider authenticationProvider() {
DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
authProvider.setUserDetailsService(userDetailsService);
authProvider.setPasswordEncoder(getPasswordEncoder());
return authProvider;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().anyRequest().authenticated().
and().formLogin().permitAll().
and().logout().permitAll();
}
@Bean(name = "passwordEncoder")
public PasswordEncoder getPasswordEncoder(){
return new BCryptPasswordEncoder(11);
}
}
UserDetailsService实现
@Service
public class UserDetailsServiceImpl extends BaseServiceImpl<User, UserRepository<User>> implements UserDetailsService, UserService {
@Override
public UserDetails loadUserByUsername(String login) throws UsernameNotFoundException {
User user = dao.findUserByLogin(login);
if (user == null) {
throw new UsernameNotFoundException(login);
}
return new UserPrincipal(user);
}
}
基于用户模型的用户详细信息
public class UserPrincipal implements UserDetails, Serializable {
private User user;
public UserPrincipal(User user) {
this.user = user;
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return null;
}
@Override
public String getPassword() {
return user.getPassword();
}
@Override
public String getUsername() {
return user.getName();
}
@Override
public boolean isAccountNonExpired() {
return user.isAccountNonExpired();
}
@Override
public boolean isAccountNonLocked() {
return user.isAccountNonLocked();
}
@Override
public boolean isCredentialsNonExpired() {
return user.isCredentialsNonExpired();
}
@Override
public boolean isEnabled() {
return user.isEnabled();
}
}
在调试模式下,我遇到了几个异常
2018-05-16 22:23:51 DEBUG InjectionMetadata:74 - Registered injected element on class [business.config.BusinessSecurityConfig$$EnhancerBySpringCGLIB$$c0bd9f7f]: AutowiredMethodElement for public org.springframework.security.authentication.dao.DaoAuthenticationProvider business.config.BusinessSecurityConfig.authenticationProvider()

和
2018-05-16 22:24:11 DEBUG AnnotationUtils:1889 - Failed to meta-introspect annotation interface org.springframework.beans.factory.annotation.Autowired: java.lang.NullPointerException
那么,这个配置有什么问题?
答案 0 :(得分:0)
因此,在配置Spring Security时我犯了一些错误。 找到这些错误有助于分析调试消息。
在更改之前调试请求的消息:
2018-06-03 00:14:26 DEBUG DispatcherServlet:891 - DispatcherServlet with name 'dispatcher' processing GET request for [/]

在这里我们可以看到两个请求。
问题是错误的道路。要解决此问题,您应该更改旧设置:
ServletRegistration.Dynamic businessDispatcher =
container.addServlet("businessDispatcher", BusinessAppConfig.createDispatcherServlet(context));
initDispatcher(businessDispatcher, 2, "/business/*");
路径更改后的调试:
2018-06-03 20:33:43 DEBUG DispatcherServlet:891 - DispatcherServlet with name 'businessDispatcher' processing GET request for [/business/]
2018-06-03 20:33:43 DEBUG RequestMappingHandlerMapping:312 - Looking up handler method for path /

2018-06-03 20:33:43 DEBUG DefaultListableBeanFactory:254 - Returning cached instance of singleton bean 'homePageController'
2018-06-03 20:33:43 DEBUG DispatcherServlet:979 - Last-Modified value for [/business/] is: -1

2018-06-03 20:33:43 DEBUG DispatcherServlet:1000 - Successfully completed request
因此,您可以在此处看到 / business / project / 网址由正确的调度程序 - businessDispatcher处理。
此外,应更改控制器@ReqestMapping 从
@Controller
@RequestMapping(value = "/business/project")
public class ProjectController {
到
@Controller
@RequestMapping(value = "/project")
public class ProjectController {
要保护方法免受浏览器地址行中的直接输入URL的影响,需要进行下一步更改:
检查 securedEnabled = true, prePostEnabled = true
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
public class BusinessSecurityConfig extends WebSecurityConfigurerAdapter {
每个控制器或特定方法都应注明 @PreAuthorize
@Controller
@RequestMapping(value = "/project")
@PreAuthorize("isAuthenticated()")
public class ProjectController {
OR
@PreAuthorize("isAuthenticated()")
@RequestMapping(value = "/new", method = RequestMethod.GET)
public String newProject (Model model) throws Exception {
model.addAttribute(new Project());
return "project/new";
}
注意如果未授权用户尝试访问受保护的方法,则会传播AuthenticationCredentialsNotFoundException。
