Java Spring Security 2用户详细信息服务问题上的自定义身份验证提供程序

我在我的webApp上安装了springsecurity2.0.5，使用默认的提供者。现在需求已经改变，我需要一个CustomAuthenticationProvider来改变身份验证方式

这是我的AuthenticationProvider

public class CustomAuthenticationProvider implements AuthenticationProvider {

@Autowired
private ParamsProperties paramsProperties;  

@SuppressWarnings("unchecked")
public Authentication authenticate(Authentication authentication) throws AuthenticationException {

    //Check username and passwd
    String user = (String) authentication.getPrincipal();
    String pass = (String) authentication.getCredentials();
    if(StringUtils.isBlank(user) || StringUtils.isBlank(pass) ){
        throw new BadCredentialsException("Incorrect username/password");
    }

    //Create SSO
    SingleSignOnService service = new SingleSignOnService(paramsProperties.getServicesServer());
    try {
        //Check logged
        service.setUsername(authentication.getName());
        service.setPassword(authentication.getCredentials().toString());
        ClientResponse response = service.call();
        String result = response.getEntity(String.class);

        ObjectMapper mapper = new ObjectMapper();
        Map<String,Object> map = mapper.readValue(result, new TypeReference<Map<String,Object>>() {} );
        //Read code
        String code = (String)map.get("code");
        log.debug(" ** [Authenticate] Result: " + code );
        for (String s : (List<String>)map.get( "messages" ) ) {
            log.debug(" [Authenticate] Message: " + s );
        }

        if ( code.equals( "SESSION_CREATED" ) || code.equals( "SESSION_UPDATED" ) || code.equals( "SESSION_VERIFIED" ) ) {              
            UsernamePasswordAuthenticationToken tokenSSO = LoginHelper.getuserSringTokenFromAuthService(map);            
            return tokenSSO;                
        } else {
            return null;
        }
    } catch (Exception e) {
        e.printStackTrace();
        throw new AuthenticationServiceException( e.getMessage() );
    }
}


public boolean supports(Class authentication) {
    return authentication.equals(UsernamePasswordAuthenticationToken.class);
}

有人能帮忙吗？

您将

authenticationProvider

bean称为用户服务，但它不是

<authentication-provider user-service-ref='authenticationProvider'>

不用说，强烈建议升级，如果没有其他原因，那么只是为了更容易获得支持。
Oops！我试过使用
，这确实有效。非常感谢你，这让我很开心。
