Spring Security 3不能與JDK 1.7一起工作

Question

我在Spring MVC項目中使用LDAP進行身份驗證的Spring Security 3。 它工作正常，直到我需要將我的項目部署到其他環境並將JDK的版本從1.6更改爲1.7。

下面

是我春天的安全配置文件和代碼示例：成功登錄後

1）安全應用程序的context.xml

     <constructor-arg ref="userService" />  
    </bean>  

    <bean id="userService" class="com.foo.auth.MyLdapUserDetailsService">

     <property name="userDetailsMapper" ref="userDetailsMapper" /> 
    </bean> 
    <bean id="userDetailsMapper" class="com.foo.auth.MyUserDetailsContextMapper">      
    </bean>   
</beans> 

2）將重定向的URL的welcome.jsp，在welcome.jsp，我使用spring security taglib獲取登錄用戶的全名。 （用於測試，我使用的主要顯示整個上下文信息）：

<security:authentication property="principal"></security:authentication>  

時使用JDK 1.6，主要節目：

com.foo.auth.MyUserDetails@3e2d20ec:......... 

，我可以用我的自定義UserDetail的屬性，例如像principal.fullName。 時使用JDK 1.7，主要節目：

​​

它沒有得到我的自定義UserDetail對象。所以如果我使用JDKk1.7，我無法正確地獲取Spring上下文。

這個問題花了我將近1周發現，根本原因是JDK版本的問題;-(

有誰知道爲什麼用LDAP Spring Security沒有在JDK1.7工作？還是我想念的東西配置？

預先感謝您！

問題解決。 這是因爲我的MyLdapAuthenticationProvider擴展錯誤提供商。 我改變MyLdapAuthenticationProvider擴展類LdapAuthenticationProvider可疑， 和彈簧安全工作˚F無論是在JDK 1.6還是1.7版本中。

這裏是我的自定義LdapAuthenticationProvider可疑：

public class MyLdapAuthenticationProvider extends LdapAuthenticationProvider { 

private static Logger logger = Logger.getLogger(MyLdapAuthenticationProvider.class);   
private MyLdapAuthenticator authenticator; 
@Autowired 
private MyLdapAuthoritiesPopulator authoritiesPopulator; 
@Autowired 
private MyUserDetailsContextMapper userDetailsContextMapper; 

public MyLdapAuthenticationProvider(LdapAuthenticator authenticator) { 
    super(authenticator); 
    this.authenticator = (MyLdapAuthenticator) authenticator; 
} 

@Override 
protected DirContextOperations doAuthentication(UsernamePasswordAuthenticationToken userToken) { 
    try { 
     DirContextOperations dirCtx = getAuthenticator().authenticate(userToken);    
     return dirCtx; 
    } catch (PasswordPolicyException ppe) { 
     throw new LockedException(this.messages.getMessage(ppe.getStatus().getErrorCode(), ppe.getStatus() 
       .getDefaultMessage())); 
    } catch (UsernameNotFoundException notFound) {    
     throw new BadCredentialsException("User Name Error!"); 
    } catch (NamingException ldapAccessFailure) { 
     throw new AuthenticationServiceException(ldapAccessFailure.getMessage(), ldapAccessFailure); 
    } 
} 

private void setAuthenticator(MyLdapAuthenticator authenticator) { 
    Assert.notNull(authenticator, "An LdapAuthenticator must be supplied"); 
    this.authenticator = authenticator; 
} 

private MyLdapAuthenticator getAuthenticator() { 
    return authenticator; 
} 

public MyUserDetailsContextMapper getUserDetailsContextMapper() { 
    return userDetailsContextMapper; 
} 

public void setUserDetailsContextMapper(MyUserDetailsContextMapper userDetailsContextMapper) { 
    this.userDetailsContextMapper = userDetailsContextMapper; 
} 

public void setAuthoritiesPopulator(MyLdapAuthoritiesPopulator authoritiesPopulator) { 
    this.authoritiesPopulator = authoritiesPopulator; 
} 

public MyLdapAuthoritiesPopulator getAuthoritiesPopulator() { 
    return authoritiesPopulator; 
} 

}
