Spring Security OAuth2：如何处理异常？

Question

我正在开发一个使用Spring Security OAuth2保护少数REST API的应用程序，现在的要求是包装Spring OAuth2异常并以JSON格式对其进行自定义。 以下是我现有的Spring安全配置，我已经尝试过此链接上提到的答案，但未成功如何包装oauth2异常

这是从OAuth获取令牌的默认网址

<http pattern="/oauth/token" create-session="never"
      authentication-manager-ref="clientAuthenticationManager"
      xmlns="http://www.springframework.org/schema/security">
    <intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_FULLY" />
    <anonymous enabled="false" />
    <http-basic entry-point-ref="clientAuthenticationEntryPoint" />
    <custom-filter ref="clientCredentialsTokenEndpointFilter"
                   after="BASIC_AUTH_FILTER" />
    <access-denied-handler ref="oauthAccessDeniedHandler" />
</http>

这将保护以下提到的以下API

<http pattern="/api/**" create-session="never"
      entry-point-ref="oauthAuthenticationEntryPoint"
      access-decision-manager-ref="accessDecisionManager"
      xmlns="http://www.springframework.org/schema/security">
    <anonymous enabled="false" />
    <intercept-url pattern="/api/api/hospital/**" access="IS_AUTHENTICATED_FULLY" />
    <custom-filter ref="resourceServerFilter" before="PRE_AUTH_FILTER" />
    <access-denied-handler ref="oauthAccessDeniedHandler" />
</http>

这用于生成密钥

自定义响应将是代码中的一个点，您可以在其中访问默认响应，并且可以发送一个POJO代替它，例如，如果您想将error_description更改为error_info或其他任何内容，或者您​​可能想向其中添加更多变量响应。 该解决方案确实存在，但是我认为至少要实现这一点很痛苦，因为我是从这里复制它的：

这个问题已经解决。 请遵循以下解决方法：1将OAuth2Exception扩展到新类，例如CustomOAuth2Exception。 在自定义类中，添加一些特定的属性。 2个自定义DefaultWebResponseExceptionTranslator并在AuthorizationServerConfiguration中注册该自定义转换器。 3个自定义的两个杰克逊序列化器，在OAuth2Exception中进行了注释，并用这两个自定义序列化器对您的CustomOAuth2Exception进行了注释。 4使用ObjectMapper用自定义序列化程序覆盖初始序列化程序。
