Question

下面是Application.java。它有调用拦截器的代码

@EnableEurekaClient
@SpringBootApplication
@EnableZuulProxy
public class Application extends WebMvcConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public TokenValidateInterceptor tokenValidateInterceptor() {
        TokenValidateInterceptor localeChangeInterceptor = new TokenValidateInterceptor();
        System.out.println("In WEB MVC Intereptor, Interceptor returned");
        return localeChangeInterceptor;
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        System.out.println("In WEB MVC Intereptor");
        // registry.addInterceptor(tokenValidateInterceptor()).addPathPatterns("/");
        registry.addInterceptor(tokenValidateInterceptor()).addPathPatterns("/api/**");
        // registry.addInterceptor(new
        // TokenValidateInterceptor()).addPathPatterns("/api/**");
    }

}

以下是拦截器代码的片段：

@Component
public class TokenValidateInterceptor extends HandlerInterceptorAdapter {

    private static final Logger LOG = Logger.getLogger(TokenValidateInterceptor.class);

    // before the actual handler will be executed ..
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
        String apikey = request.getHeader("apikey");
        // if (LOG.isDebugEnabled()) {
        LOG.info("#### Starting TokenValidateInterceptor.preHandle ####");
        LOG.info("apikey-->" + apikey);
        // }
        if (StringUtils.isBlank(apikey) || apikey == null || apikey.isEmpty()) {
                return true;
        }
}
}

但是呼叫没有到达拦截器的预处理。

Answer 1

AFAIK，Zuul路由中定义的所有请求都由ZuulServlet处理。 Spring MVC不处理这些请求，因此不会为这些请求调用任何Spring HandlerInterceptor。如果您需要对API请求进行任何预处理，则应在Zuul预过滤器或servlet过滤器中实现它。

为Spring启动应用程序启用Zuul代理后（我们有一套miroservices），spring mvc拦截器无效
