在我的项目中实现了spring security的实现，但是我在定义重定向时遇到了麻烦。当访问被锁定时，我需要将该用户重定向到特定的 URL。

当我放置标签“access-denied-handler”时，我希望他重定向到 bean 上定义的页面，但不要发生。

我发现发生了什么。我有一个 Spring MVC @ExceptionHandler，他正在捕获错误。

@ExceptionHandler
public ResponseEntity<String> handle(Exception exception, HttpServletRequest requestMain) {
    String erro = exception.getMessage();
    PusherRequest request = new PusherRequest("hemisphere-web", requestMain.getSession().getId());
    request.triggerPush(erro);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);

    return new ResponseEntity<String>(exception.getMessage(), headers, HttpStatus.FORBIDDEN);
}

重定向有自己的 HTTP 状态码 (3xx)，请参见http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html。该方法response.sendRedirect应自动将 HTTP 状态代码设置为 307（临时重定向，请参阅http://docs.oracle.com/javaee/5/api/javax/servlet/http/HttpServletResponse.html#sendRedirect）。

但是您在重定向之前将 HTTP 状态代码设置为 Forbidden (403)。

因此尝试删除response.setStatus(HttpServletResponse.SC_FORBIDDEN). 您还可以发布curl转储以查看原始服务器输出。
