问题：

org.springframework.boot.web.servlet.error.错误ontroller.get错误路径（）

2023-03-14

我的应用程序使用spring boot版本2.5.0和spring cloud starter netflix zuul 2.2.8。释放

在最新的spring boot版本2.5.0中，getErrorPath（）API从ErrorController中删除，但最新的spring cloud starter netflix zuul 2.2.8。RELEASE仍调用此API并导致此错误

有人遇到同样的问题并已经解决了吗

为什么会出现这个问题？

出现此问题是因为zuul和功能区已从2.5. x中的springboot主通道中删除。

我们如何解决这个问题？

将：Zuul（Api网关）替换为Spring Cloud gateway，将Ribbon（负载平衡器）替换为Spring Cloud Loadbalancer。您可以通过此博客获取说明：https://spring.io/blog/2018/12/12/spring-cloud-greenwich-rc1-available-now#spring-云网飞项目进入维护模式

使用@Configuration注释创建Bean：

创建一个ZuulConfiguration.java类并使用以下代码：

@Configuration
public class ZuulConfiguration {

    /** The path returned by ErrorContoller.getErrorPath() with Spring Boot < 2.5 (and no longer available on Spring Boot >= 2.5). */
    private static final String ERROR_PATH = "/error";

    /**
     * Constructs a new bean post-processor for Zuul.
     * 
     * @param routeLocator
     *            the route locator.
     * @param zuulController
     *            the Zuul controller.
     * @param errorController
     *            the error controller.
     * @return the new bean post-processor.
     */
    @Bean
    public ZuulPostProcessor zuulPostProcessor(@Autowired RouteLocator routeLocator, @Autowired ZuulController zuulController,
            @Autowired(required = false) ErrorController errorController) {
        return new ZuulPostProcessor(routeLocator, zuulController, errorController);
    }

    private static final class ZuulPostProcessor implements BeanPostProcessor {

        private final RouteLocator routeLocator;

        private final ZuulController zuulController;

        private final boolean hasErrorController;

        ZuulPostProcessor(RouteLocator routeLocator, ZuulController zuulController, ErrorController errorController) {
            this.routeLocator = routeLocator;
            this.zuulController = zuulController;
            this.hasErrorController = (errorController != null);
        }

        @Override
        public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
            if (hasErrorController && (bean instanceof ZuulHandlerMapping)) {
                Enhancer enhancer = new Enhancer();
                enhancer.setSuperclass(ZuulHandlerMapping.class);
                enhancer.setCallbackFilter(LookupHandlerCallbackFilter.INSTANCE); // only for lookupHandler
                enhancer.setCallbacks(new Callback[] { LookupHandlerMethodInterceptor.INSTANCE, NoOp.INSTANCE });
                Constructor<?> ctor = ZuulHandlerMapping.class.getConstructors()[0];
                return enhancer.create(ctor.getParameterTypes(), new Object[] { routeLocator, zuulController });
            }
            return bean;
        }

    }

    private static enum LookupHandlerCallbackFilter implements CallbackFilter {

        INSTANCE;

        @Override
        public int accept(Method method) {
            if ("lookupHandler".equals(method.getName())) {
                return 0;
            }
            return 1;
        }

    }

    private static enum LookupHandlerMethodInterceptor implements MethodInterceptor {

        INSTANCE;

        @Override
        public Object intercept(Object target, Method method, Object[] args, MethodProxy methodProxy) throws Throwable {
            if (ERROR_PATH.equals(args[0])) {

                /* by entering this branch we avoid the ZuulHandlerMapping.lookupHandler method to trigger the NoSuchMethodError */
                return null;
            }
            return methodProxy.invokeSuper(target, args);
        }

    }

}

我也面临同样的问题，因为自2020年以来，spring cloud就不再支持zuul了

spring-boot-starter-parent: 2.1.3.RELEASE
java.version: 1.8
spring-cloud.version: Greenwich.RELEASE
spring-cloud-starter-netflix-zuul: 2.1.0.RELEASE
spring-cloud-starter-netflix-eureka-client: 2.1.0.RELEASE
jackson-dataformat-xml: 2.9.9

问题是组织之间的Spring版本冲突。springframework。云：spring cloud starter netflix zuul:2.2。x和Spring护套2.5。x

这里提到的aldobongio的解决方法/修复对我有用：https://gist.github.com/aldobongio/6a22f49863c7a777612f7887bbb8fd1d

这段代码创建了一个新的BeanPostProcessor，它围绕原始的ZuulHandlerMappingBean包装了一个自定义代理。此代理拦截lookupHandler方法的调用，阻止执行导致“NoSuchMethodError”的代码。
