  • spring cloud gateway网关启动报错:No qualifying bean of type 'org.springframework.web.reactive.DispatcherHandler'

    网关配置好后启动报错如下:

    org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'servletEndpointRegistrar' defined in class path resource [org/springframework/boot/actuate/autoconfigure/endpoint/web/ServletEndpointManagementContextConfiguration$WebMvcServletEndpointManagementContextConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.actuate.endpoint.web.ServletEndpointRegistrar]: Factory method 'servletEndpointRegistrar' threw exception; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'gatewayControllerEndpoint' defined in class path resource [org/springframework/cloud/gateway/config/GatewayAutoConfiguration$GatewayActuatorConfiguration.class]: Unsatisfied dependency expressed through method 'gatewayControllerEndpoint' parameter 2; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'hystrixGatewayFilterFactory' defined in class path resource [org/springframework/cloud/gateway/config/GatewayAutoConfiguration$HystrixConfiguration.class]: Unsatisfied dependency expressed through method 'hystrixGatewayFilterFactory' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.web.reactive.DispatcherHandler' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

    只需要把 spring-boot-starter-web 进行排除就 OK 了:

    <dependency>
                <groupId>cn.miaoying</groupId>
                <artifactId>common</artifactId>
                <version>${common.version}</version>
                <exclusions>
                    <exclusion>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-starter-web</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
