前端用的vue，后台SpringBoot，浏览器ie11。问题背景：前端的菜单为了权限问题是通过请求后端获取到的，在ie浏览器上退出登录后用其它角色账号登录后重新请求菜单的时候显示的是上个用户的菜单缓存，其他类似的请求也有同样的问题
解决方案：
后端写个全局的拦截器将所有的响应头等设置一下，具体如下：
继承HandlerInterceptorAdapter 重写它的preHandle方法，设置响应
public class LoginInterceptor extends HandlerInterceptorAdapter {private Logger logger = LoggerFactory.getLogger(LoginInterceptor.class);@Autowiredprivate JwtTokenUtil jwtTokenUtil;@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {// System.out.println("path===="+request.getRequestURI());// String authToken = request.getHeader(jwtTokenUtil.getHeader());//// if(StringUtils.isBlank(authToken)){// throw new TokenException("用户未登录");// }// if(!RedisUtils.exists(CommonConstants.REDIS_TOKEN_VALUE + authToken)) {// throw new TokenException("无效的token");// }//// JwtUser jwtUser = jwtTokenUtil.validate(authToken);// if(jwtUser == null){//throw new TokenException("无效的token");// }// BaseContextHandler.set(CommonConstants.USER_INFO, jwtUser);response.setHeader("Cache-Control","no-cache");response.setHeader( "Pragma", "no-cache" );response.addHeader( "Cache-Control", "must-revalidate" );response.addHeader( "Cache-Control", "no-cache" );response.addHeader( "Cache-Control", "no-store" );response.setDateHeader("Expires", 0);return super.preHandle(request, response, handler);}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {BaseContextHandler.remove();super.afterCompletion(request, response, handler, ex);}}
