AuthenticationSuccessHandler上的Spring MVC响应

Question

假设有一个要登录的REST API：

/api/user/login

在Spring安全性中，很容易替换HTTP入口点/成功处理程序/失败处理程序，如下所示

<http 
    pattern="/**" 
    use-expressions="true"
    entry-point-ref="restAuthenticationEntryPoint">
    <form-login
        authentication-success-handler-ref="mySuccessHandler"
        authentication-failure-handler-ref="myFailureHandler"
        login-processing-url="/api/user/login"
        username-parameter="login"
        password-parameter="password"/>
    <logout 
        invalidate-session="true" 
        delete-cookies="WSESSIONID" 
        logout-url="/api/user/logout"/>
    <csrf disabled="true"/>
    <session-management>
        <concurrency-control max-sessions="1" />
    </session-management>
    ....
</http>

并在成功/失败状态下生成自定义响应：

public class RestUrlAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) throws ServletException, IOException {
        response.getOutputStream().write("success".getBytes());
        clearAuthenticationAttributes(request);
    }
}

我正在寻找一种在成功和失败状态下返回与Spring MVC控制器相同的对象的方法。在这种情况下，响应编码必须与MVC控制器相同，并考虑从请求标头接受。
