[Java知识库]springboot放行静态资源

F12看看你的请求要访问哪些静态资源，然后用/**/*.xx的格式写即可

如果拦截器已经写好了，就不用看下面这个拦截器代码了

@Component
@Slf4j
public class AuthInterceptor implements HandlerInterceptor {

    @Value("${delivery.auth.activate}")
    private boolean activate;

    @Autowired
    private HttpSession sess;
    
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {

        // 不用自己放行了，在webConfig里面设置路径即可
//        // 对注册&登录&注销操作放行
//        String uri = request.getRequestURI();
//        if(uri.startsWith("user")) {
//            return true;
//        }

        // 根据session的用户是否登录
        if (request.getSession().getAttribute("userId") == null) {
            response.setCharacterEncoding("UTF-8");
            response.setContentType("application/json; charset=utf-8");
            try (PrintWriter out = response.getWriter()) {
                Message msg = Message.fail("用户未登录");
                out.append(JSON.toJSONString(msg));
                return false;
            } catch (Exception e) {
                log.error(e.getMessage());
                response.sendError(500);
                return false;
            }
        }
        return true;
    }
}

配置类中加上url规则

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Autowired
    private AuthInterceptor interceptor;


    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**");
    }

    /**
     * 开启自己的拦截器
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // 添加拦截器，配置拦截地址
        registry.addInterceptor(interceptor)
//                .addPathPatterns("/order/**")
                // 放行静态资源
                .excludePathPatterns("/user/**", "/**/*.html", "/**/*.css", "/**/*.js", "/**/*.woff", "/custom/**");
    }
}
