关于filter内代码的相关问题

public class AdminFilter implements Filter {
    @Autowired
    private UserService userService;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
            throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) servletRequest;
        HttpSession session = request.getSession();
        User loginUser = (User) session.getAttribute(Constant.LOGIN_USER);
        if(loginUser == null) {
            print(servletResponse, BusinessExceptionEum.NEED_LOGIN);
            return;
        }
        if (userService.checkAdminRole(loginUser)) {
            filterChain.doFilter(servletRequest, servletResponse);
        } else {
            print(servletResponse, BusinessExceptionEum.ACCESS_DENY);
        }
    }

    @Override
    public void destroy() {
    }

    private void print(ServletResponse servletResponse,
                         BusinessExceptionEum businessExceptionEum) throws IOException {
            PrintWriter out = new HttpServletResponseWrapper((HttpServletResponse) servletResponse).getWriter();
        out.write("{\n"
                + "    \"status\": "+ businessExceptionEum.getCode() + ",\n"
                + "    \"msg\": \"" + businessExceptionEum.getMsg() + "\",\n"
                + "    \"data\": null\n"
                + "}");
        out.flush();
        out.close();
    }
}

问题描述：

• HttpServletResponseWrapper.getWritter.write中如果输出中文字符会出现乱码，请问如何解决

• 被Filter拦截的数据就不能在WebLogAspect捕捉了，要想被这个Aspect拦截，要怎么操作，是要加什么JoinCut吗？

public class WebLogAspect {
    private final Logger log = LoggerFactory.getLogger(WebLogAspect.class);
    @Pointcut("execution (public * i3kp0d.proj.work.mall.controller.*.*(..))")
    public void webLog() {

    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) {
        ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = requestAttributes.getRequest();

        log.info("URL : " + request.getRequestURI());
        log.info("HTTP_METHOD : " + request.getMethod());
        log.info("IP : " + request.getRemoteAddr());
        log.info("CLASS_METHOD : " + joinPoint.getSignature().getName() + "." + joinPoint.getSignature().getName());
        log.info("ARGS : " + Arrays.toString((joinPoint.getArgs())));
    }

    @AfterReturning(returning = "res", pointcut = "webLog()")
    public void doAfterReturning(Object res) throws JsonProcessingException {
        log.info("RESPONSE : " + new ObjectMapper().writeValueAsString(res));
    }

}
