Spring Security OAuth2更改JSON错误响应格式

Question

我有一个基于Spring Security OAuth2的RESTful应用程序。 我一直在尝试将默认的Spring Security消息格式从XML更改为JSON，并且已经部分成功。

例如 - 我想出了当请求不包含Bearer令牌时如何更改响应格式（以下行代码）

<bean id="oauthAuthenticationEntryPoint" class ="c.s.m.security.CustomAuthenticationEntryPoint" />

但我无法弄清楚如何捕获/更改以下两项的格式。

1. 当在安全URL中传递无效令牌时，Spring Security当前会返回。 我在哪里更改此格式？

    {"error": "invalid_token","error_description": "Invalid access token: 144285e3-9563-420e-8ce"} 

2. 如何更改BadCredentialsException JSON格式？ 目前，它返回类似于上面的JSON？

下面是我的applicationContext.xml

<sec:http pattern="/oauth/token" create-session="stateless"
    use-expressions="true" authentication-manager-ref="authenticationManager">
    <sec:csrf disabled="true" />
    <sec:anonymous enabled="false" />
    <sec:http-basic entry-point-ref="clientAuthenticationEntryPoint" />
    <sec:custom-filter ref="clientCredentialsTokenEndpointFilter" before="BASIC_AUTH_FILTER" />
    <sec:access-denied-handler ref="oauthAccessDeniedHandler" />
</sec:http>
<sec:authentication-manager alias="authenticationManager"
    erase-credentials="false">
    <sec:authentication-provider user-service-ref="clientDetailsUserService" />
</sec:authentication-manager>

<bean id="clientDetailsUserService" class="org.springframework.security.oauth2.provider.client.ClientDetailsUserDetailsService">

    <property name="typeName" value="Basic" />
</bean>

<bean id="clientCredentialsTokenEndpointFilter" class="org.springframework.security.oauth2.provider.client.ClientCredentialsTokenEndpointFilter">
    <property name="authenticationManager" ref="authenticationManager" />
</bean>

<!-- Oauth handler Access Denied Handler -->

<bean id="oauthAccessDeniedHandler" class="c.s.m.security.CustomAccessDeniedHandler" />
    <!-- class="org.springframework.security.oauth2.provider.error.OAuth2AccessDeniedHandler" /> -->

<!-- Server resource -->

<sec:http pattern="/api/**" create-session="never"
    entry-point-ref="oauthAuthenticationEntryPoint" use-expressions="true" >

    <sec:custom-filter ref="resourceServerFilter"
        before="PRE_AUTH_FILTER" />
    <sec:access-denied-handler ref="oauthAccessDeniedHandler" />
</sec:http>

<!-- Entry point resource -->

<bean id="oauthAuthenticationEntryPoint" class ="c.s.m.security.CustomAuthenticationEntryPoint" />          

<oauth:resource-server id="resourceServerFilter" resource-id="springsec" token-services-ref="tokenServices" />

<bean id="tokenServices"
    class="org.springframework.security.oauth2.provider.token.DefaultTokenServices" >
    <property name="tokenStore" ref="tokenStore" />
    <property name="supportRefreshToken" value="true" />
    <property name="accessTokenValiditySeconds" value="300000" />
    <property name="clientDetailsService" ref="clientDetails" />
</bean>    
<bean id="tokenStore"  class="org.springframework.security.oauth2.provider.token.store.JdbcTokenStore">

</bean>

    <oauth:implicit />
    <oauth:refresh-token />
    <oauth:client-credentials />
    <oauth:password authentication-manager-ref="userAuthenticationManager" />
</oauth:authorization-server>

<sec:authentication-manager id="userAuthenticationManager">

</sec:authentication-manager>
