代码赘余

老哥，
JWTFilter.java中的这段：
/**
* 对跨域提供支持
*/
@OverRide
protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception {

    HttpServletRequest httpServletRequest = (HttpServletRequest) request;
    HttpServletResponse httpServletResponse = (HttpServletResponse) response;
    httpServletResponse.setHeader("Access-control-Allow-Origin", httpServletRequest.getHeader("Origin"));
    httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET,POST,OPTIONS,PUT,DELETE");
    httpServletResponse.setHeader("Access-Control-Allow-Headers", httpServletRequest.getHeader("Access-Control-Request-Headers"));

    // 跨域时会首先发送一个option请求，这里我们给option请求直接返回正常状态
    if (httpServletRequest.getMethod().equals(RequestMethod.OPTIONS.name())) {

        httpServletResponse.setStatus(HttpStatus.OK.value());

        return false;

    }

    return super.preHandle(request, response);

}

对跨域的支持已经淘汰了，直接@crossorigin解决一切问题！
