继承handlerInterceptor的拦截器
@Component public class LoginInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { User user = (User) request.getSession().getAttribute("user"); if (user == null || user.getUsername() == null || user.getUsername().equals("")) { response.sendRedirect("/login"); return false; } return true; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { } }
@Configuration public class WebMvcConfig implements WebMvcConfigurer { private final String dirName = System.getProperty("user.dir") + "\\images\\car\\"; private final LoginInterceptor loginInterceptor; private final Logger logger = LoggerFactory.getLogger(FileService.class); public WebMvcConfig(LoginInterceptor loginInterceptor) { this.loginInterceptor = loginInterceptor; } @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { String dir = dirName.replace("\\", "/"); logger.info(dir); registry.addResourceHandler("/img/car/**") .addResourceLocations("file:///" + dir); } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(loginInterceptor) .excludePathPatterns("/login") //不拦截的 .excludePathPatterns("/dist/**") .excludePathPatterns("classpath:/static/**") .excludePathPatterns("/carinfo/up").excludePathPatterns("/carinfo/upb") .addPathPatterns("/**"); } }
