此处以JwtInterceptor  为例,不需要其它配置

@Componentpublic class JwtInterceptor extends HandlerInterceptorAdapter {    @Autowired    private Jwtutil jwtutil;    @Autowired    private SysUserService sysUserService;    @Override    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {        String header = request.getHeader("Authorization");        if (!StringUtils.isEmpty(header)) {            Claims claims = jwtutil.parsetToken(header);            String username = (String) claims.get("username");            String role = (String) claims.get("role");            Integer sysUserId = Integer.valueOf(claims.getId());            SysUser sysUser = sysUserService.selectByPrimaryKey(sysUserId);            if (sysUser==null) throw new UserNotLoginException();            request.setAttribute("sysUser", sysUser);            request.setAttribute("sysUserId", sysUserId);            request.setAttribute("username", username);            request.setAttribute("role", role);        }        String url = request.getRequestURL().toString();        System.out.println(url);        /**         *         * 此处所有请求放行         */        return true;    }}
