我的Spring安全性运行良好,但经过一段时间后,当用户访问页面时,我开始收到大量异常。
我注意到session and principal is null
这就是我收到错误500的原因。
如何再次将用户重定向到登录?
或者我可以简单地删除会话超时(我真的不需要它)
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled=true)
@ComponentScan("pt.impactzero.atp")
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private MyUserDetailsService myUserDetailsService;
@Autowired
private AuthenticationSuccessHandler authenticationSuccessHandler;
@Autowired
private LogoutSuccessHandler logoutSuccessHandler;
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/").hasAnyRole("Administrator" , "Member")
.and()
.formLogin()
.loginPage("/login").permitAll()
.defaultSuccessUrl("/dashboard",true)
.failureUrl("/login?error")
.successHandler(authenticationSuccessHandler)
.and()
.logout()
.logoutUrl("/logout").permitAll()
.logoutSuccessUrl("/login")
.logoutSuccessHandler(logoutSuccessHandler)
.and()
.csrf().disable();
}
@Override
public void configure(WebSecurity web) {
web.httpFirewall(allowUrlEncodedSlashHttpFirewall());
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(myUserDetailsService).passwordEncoder(passwordEncoder());
}
@Bean
public PasswordEncoder passwordEncoder() {
BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
return passwordEncoder;
}
@Bean
public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
DefaultHttpFirewall firewall = new DefaultHttpFirewall();
firewall.setAllowUrlEncodedSlash(true);
return firewall;
}
@Bean
public CommonsMultipartResolver filterMultipartResolver(){
return new CommonsMultipartResolver();
}
//Online users
@Bean
public ActiveUsers activeUsers(){
return new ActiveUsers();
}
}

如果您想要禁用会话,您可以:
@Override
protected void configure(HttpSecurity http) throws Exception {
// disable session
http.sessionManagement().disable()
.authorizeRequests().antMatchers("/").hasAnyRole("Administrator" , "Member")
.and()
.formLogin()
.loginPage("/login").permitAll()
.defaultSuccessUrl("/dashboard",true)
.failureUrl("/login?error")
.successHandler(authenticationSuccessHandler)
.and()
.logout()
.logoutUrl("/logout").permitAll()
.logoutSuccessUrl("/login")
.logoutSuccessHandler(logoutSuccessHandler)
.and()
.csrf().disable();
}
如果您想将用户重定向到登录页面,可以试试这个:
@Override
protected void configure(HttpSecurity http) throws Exception {
// redirect user to login page
http.sessionManagement().invalidSessionUrl("http://your.login.page").and()
.authorizeRequests().antMatchers("/").hasAnyRole("Administrator" , "Member")
.and()
.formLogin()
.loginPage("/login").permitAll()
.defaultSuccessUrl("/dashboard",true)
.failureUrl("/login?error")
.successHandler(authenticationSuccessHandler)
.and()
.logout()
.logoutUrl("/logout").permitAll()
.logoutSuccessUrl("/login")
.logoutSuccessHandler(logoutSuccessHandler)
.and()
.csrf().disable();
}
