使用 Spring Security 3.2.2 和 Spring Framework 3.2.8 的以下 Java Config 配置，即使我使用“.eraseCredentials(false)”，用户密码也会被删除，并且它无法使用 < em="">authentication.getCredentials()。

@Configuration

    }

    @Bean( name = "acessDeniedHandler" )
    public AccessDeniedHandler acessDeniedHandler() {

        XhrAwareAccessDeniedHandlerImpl xhrAwareAccessDeniedHandler = new XhrAwareAccessDeniedHandlerImpl();
        xhrAwareAccessDeniedHandler.setErrorPage( "/denied" );
        return xhrAwareAccessDeniedHandler;
    }

    @Bean( name = "atlasAuthenticationSuccessHandler" )
    public AtlasAuthenticationSuccessHandler atlasAuthenticationSuccessHandler() {

        return new AtlasAuthenticationSuccessHandler( "/views/hub" );
    }

    @Bean( name = "atlasAuthenticationFailureHandler" )
    public AtlasAuthenticationFailureHandler atlasAuthenticationFailureHandler() {
        return new AtlasAuthenticationFailureHandler( "/home?loginError=error" );
    }

    @Bean( name = "atlasLogoutSuccessHandler" )
    public AtlasLogoutSuccessHandler atlasLogoutSuccessHandler() {
        AtlasLogoutSuccessHandler atlasLogoutSuccessHandler = new AtlasLogoutSuccessHandler();
        atlasLogoutSuccessHandler.setDefaultTargetUrl( "/home?logoff=disconnect" );
        return atlasLogoutSuccessHandler;
    }

    @Override
    public void configure( WebSecurity web ) throws Exception {

        web.ignoring().antMatchers( "/resources/**" );

            return new PropertySourcesPlaceholderConfigurer();
        }

        @Bean( name = "contextSource" )
        public DefaultSpringSecurityContextSource contextSource() {

            DefaultSpringSecurityContextSource contextSource =
                    new DefaultSpringSecurityContextSource( "ldap://" + this.host + ":" + this.port );
            contextSource.setUserDn( this.userDn );
            contextSource.setPassword( this.password );
            return contextSource;
        }

        @Bean( name = "userSearch" )
        public FilterBasedLdapUserSearch userSearch() {

            return new FilterBasedLdapUserSearch( this.baseDn, "(bsalias={0})", this.contextSource() );
        }

        @Bean( name = "ldapAuthenticator" )
        public LdapAuthenticator ldapAuthenticator() {

            BindAuthenticator authenticator = new BindAuthenticator( this.contextSource() );
            authenticator.setUserSearch( this.userSearch() );
            return authenticator;
        }

        @Bean( name = "atlasAuthoritiesPopulator" )
        public AtlasAuthoritiesPopulator atlasAuthoritiesPopulator() {

            return new AtlasAuthoritiesPopulator();
        }

            return new LdapAuthenticationProvider( this.ldapAuthenticator(), this.atlasAuthoritiesPopulator() );
        }

        @Autowired
        public void configureGlobal( AuthenticationManagerBuilder auth ) throws Exception {

            auth.eraseCredentials( false ).authenticationProvider( this.ldapAuthenticationProvider() );
        }
    }
}

但是，使用同样的spring security和spring framework的xml配置运行正常，密码可用。

你有什么线索吗？我该如何解决？

提前致谢。

最佳答案

这是影响全局身份验证选项的 Spring Security Java 配置中的错误。参见 SEC-2533了解详情。没有真正简单的解决此问题的方法，但该错误已修复，将在未来几天内发布。

关于java - 使用 Java Config 的 Spring Security 无法使用 eraseCredentials 方法，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22633668/
