Spring security kerberos 适用于 xml config，但不适用于 Java config

Question

我尝试了 spring security kerberos 的例子，然后是 java config。它是完全相同的配置(一个在xml中，一个在java中(。

当我将该项目与 xml 配置一起使用时，它可以工作。 但是，当我将项目与 java 配置一起使用时，我有这个堆栈跟踪：

我不明白为什么它适用于 xml 配置，而不是 java 配置。我花了很多时间去寻找，但我绝望了。 这是我的 xml 配置：

</bean>
<bean id="dummyUserDetailsService" class="demo.DummyUserDetailsService" />

这是我的java配置：

@Configuration
@EnableWebMvcSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Value("${app.service-principal}")
private String servicePrincipal;
@Value("${app.keytab-location}")
private String keytabLocation;
@Bean
public AuthenticationManager customAuthenticationManager() throws Exception {
return authenticationManager();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.exceptionHandling()
.authenticationEntryPoint(spnegoEntryPoint())
.and()
.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login").permitAll()
.and()
.logout()
.permitAll()
.and()
.addFilterBefore(
spnegoAuthenticationProcessingFilter(authenticationManagerBean()),
BasicAuthenticationFilter.class);
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth
.authenticationProvider(kerberosAuthenticationProvider())
.authenticationProvider(kerberosServiceAuthenticationProvider());
}
@Bean
public KerberosAuthenticationProvider kerberosAuthenticationProvider() {
KerberosAuthenticationProvider provider = new KerberosAuthenticationProvider();
SunJaasKerberosClient client = new SunJaasKerberosClient();
client.setDebug(true);
provider.setKerberosClient(client);
provider.setUserDetailsService(dummyUserDetailsService());
return provider;
}
@Bean
public SpnegoEntryPoint spnegoEntryPoint() {
return new SpnegoEntryPoint("/login");
}
@Bean
public SpnegoAuthenticationProcessingFilter spnegoAuthenticationProcessingFilter(
AuthenticationManager authenticationManager) {
SpnegoAuthenticationProcessingFilter filter = new SpnegoAuthenticationProcessingFilter();
filter.setAuthenticationManager(authenticationManager);
return filter;
}
@Bean
public KerberosServiceAuthenticationProvider kerberosServiceAuthenticationProvider() {
KerberosServiceAuthenticationProvider provider = new KerberosServiceAuthenticationProvider();
provider.setTicketValidator(sunJaasKerberosTicketValidator());
provider.setUserDetailsService(dummyUserDetailsService());
return provider;
}
@Bean
public SunJaasKerberosTicketValidator sunJaasKerberosTicketValidator() {
SunJaasKerberosTicketValidator ticketValidator = new SunJaasKerberosTicketValidator();
ticketValidator.setServicePrincipal(servicePrincipal);
ticketValidator.setKeyTabLocation(new FileSystemResource(keytabLocation));
ticketValidator.setDebug(true);
//ticketValidator.setHoldOnToGSSContext(true);
return ticketValidator;
}
@Bean
public DummyUserDetailsService dummyUserDetailsService() {
return new DummyUserDetailsService();
}
}

我指定对两个项目使用相同的密钥表，使用相同的 spring 引导配置在相同的环境中编译。

使用 xml 配置，日志显示

而使用 Java 配置示例，我只有

我忘记了什么吗？

Answer 1

对于 xml config，在 application.yml 中，键表位置必须是以"file://"开头的绝对路径

keytab-location: file:///tmp/krb5.keytab

使用 java config，在 application.yml 中，密钥表位置必须是需要文件协议的相对路径。

keytab-location: krb5.keytab
