My application use spring-boot version 2.5.0 and spring-cloud-starter-netflix-zuul 2.2.8.RELEASE

With latest spring-boot version 2.5.0, getErrorPath() API is removed from ErrorController, but latest spring-cloud-starter-netflix-zuul 2.2.8.RELEASE still calls this API and causes this error

Has anyone got the same issue and resolved already

  • Which means they aren't compatible. So either don't use Spring Boot 2.5 and stick with 2.4 or find a more recent version of Spring Cloud (which afaik isn't yet available). Commented Jun 23, 2021 at 13:38

    As defined in this link spring.io/projects/spring-cloud, 2020.0.x aka Ilford should be compatible with boot version 2.4.x, 2.5.x (Starting with 2020.0.3). Another thing, this API is removed from Spring Boot 2.3 :( Commented Jun 23, 2021 at 14:25
  • That is compatible but the spring-cloud-starter-netflix-zuul version you are using isn't. As that isn't part of that release train (and hasn't been for quite some time). Commented Jun 23, 2021 at 14:54
  • I am facing the same issue. What can I do to solve this? I need to use netflix-zuul library so can not remove it. Commented Jul 15, 2021 at 12:26

    @Kekar, you can use spring-boot 2.2.13 temporarily, it's compatible with spring-cloud-starter-netflix-zuul 2.2.8 Commented Jul 20, 2021 at 10:13

The problem is the Spring version conflict between org.springframework.cloud:spring-cloud-starter-netflix-zuul:2.2.x and Spring Boot 2.5.x

This workaround / fix of aldobongio mentioned here worked for me: https://gist.github.com/aldobongio/6a22f49863c7a777612f7887bbb8fd1d

This code creates a new BeanPostProcessor that wraps a custom proxy around the original ZuulHandlerMapping bean. This proxy intercepts the invocation of the lookupHandler method preventing the execution of the code leading to "NoSuchMethodError".

import java.lang.reflect.Constructor; import java.lang.reflect.Method; import org.springframework.beans.BeansException; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.config.BeanPostProcessor; import org.springframework.boot.web.servlet.error.ErrorController; import org.springframework.cglib.proxy.Callback; import org.springframework.cglib.proxy.CallbackFilter; import org.springframework.cglib.proxy.Enhancer; import org.springframework.cglib.proxy.MethodInterceptor; import org.springframework.cglib.proxy.MethodProxy; import org.springframework.cglib.proxy.NoOp; import org.springframework.cloud.netflix.zuul.filters.RouteLocator; import org.springframework.cloud.netflix.zuul.web.ZuulController; import org.springframework.cloud.netflix.zuul.web.ZuulHandlerMapping; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; /** * Fix for Zuul configuration with Spring Boot 2.5.x + Zuul - "NoSuchMethodError: ErrorController.getErrorPath()": */ @Configuration public class ZuulConfiguration { /** * The path returned by ErrorController.getErrorPath() with Spring Boot < 2.5 * (and no longer available on Spring Boot >= 2.5). */ private static final String ERROR_PATH = "/error"; private static final String METHOD = "lookupHandler"; /** * 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 enum LookupHandlerCallbackFilter implements CallbackFilter { INSTANCE; @Override public int accept(Method method) { if (METHOD.equals(method.getName())) { return 0; } return 1; } } private 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); } } 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; } } }

I faced the same issue because spring cloud did not support zuul since 2020.
spring-cloud and netflix-zuul will work properly as following versions.

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 spring-cloud-starter-netflix-eureka-server: 2.1.0.RELEASE

Why this issue occurs?

  • This issue occurs because zuul and ribbon were removed from the springboot main channel in 2.5.x.

How can we solve this issue?

  1. Replacing: Zuul (Api gateway) by Spring Cloud Gateway and Ribbon(Load balancer) by Spring Cloud Loadbalancer. You can go through this blog to get instructions: https://spring.io/blog/2018/12/12/spring-cloud-greenwich-rc1-available-now#spring-cloud-netflix-projects-entering-maintenance-mode

  2. Creating a Bean using @Configuration annotation:

  • Create a ZuulConfiguration.java class and use this code:
@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); } } }

Downgrading spring cloud version solved issue.

<spring-cloud.version>Hoxton.SR6</spring-cloud.version>

Properties also changed as Below

zuul.routes.serviceone.path=/user/** zuul.routes.serviceone.url=USERSERVICE

Info: I'm using Spring boot version 2.6.1, spring-cloud-starter-netflix-zuul 2.2.10.RELEASE And the solution (new BeanPostProcessor that wraps a custom proxy around the original ZuulHandlerMapping bean.) posted by electrobabe, works fine!!!
