使用OAuth2从Spring Security自定义身份验证错误

我想知道是否可以自定义以下授权错误：

{
  "error": "unauthorized",
  "error_description": "Full authentication is required to access this resource"
}

当用户请求没有权限时，我得到了它。我想将其自定义为与Spring Boot错误非常相似：

{
 "timestamp":1445441285803,
 "status":401,
 "error":"Unauthorized",
 "message":"Bad credentials",
 "path":"/oauth/token"
}

有可能吗

非常感谢。

回答：

我需要创建一个新类，该类实现“ AuthenticationEntryPoint”，如下所示：

public class AuthExceptionEntryPoint implements AuthenticationEntryPoint
{
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException arg2) throws IOException, ServletException
    {
        final Map<String, Object> mapBodyException = new HashMap<>() ;
        mapBodyException.put("error"    , "Error from AuthenticationEntryPoint") ;
        mapBodyException.put("message"  , "Message from AuthenticationEntryPoint") ;
        mapBodyException.put("exception", "My stack trace exception") ;
        mapBodyException.put("path"     , request.getServletPath()) ;
        mapBodyException.put("timestamp", (new Date()).getTime()) ;
        response.setContentType("application/json") ;
        response.setStatus(HttpServletResponse.SC_UNAUTHORIZED) ;
        final ObjectMapper mapper = new ObjectMapper() ;
        mapper.writeValue(response.getOutputStream(), mapBodyException) ;
    }
}

并将其添加到我的ResourceServerConfigurerAdapter实现中：

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter
{   
    @Override
    public void configure(HttpSecurity http) throws Exception
    {
        http.exceptionHandling().authenticationEntryPoint(new AuthExceptionEntryPoint()) ;
    }
}
