Question

说明：无法启动web服务器； 嵌套异常是 org.springframework.boot.web.server.WebServerException：无法启动嵌入式 Tomcat

启动 Tomcat 上下文时出错。 例外：

org.springframework.beans.factory.BeanCreationException。 消息：在 class 路径资源 [org/springframework/boot/actuate/autoconfigure/endpoint/web/ServletEndpointManagementContextConfiguration$WebMvcServletEndpointManagementContextConfiguration.class] 中定义名称为 'servletEndpointRegistrar' 的 bean 创建错误：通过工厂方法进行 Bean 实例化失败； 嵌套异常是 org.springframework.beans.BeanInstantiationException：无法实例化 [org.springframework.boot.actuate.endpoint.web.ServletEndpointRegistrar]：工厂方法“servletEndpointRegistrar”抛出异常； 嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException：在 class 路径资源 [org/springframework/cloud/gateway/config/GatewayAutoConfiguration$GatewayActuatorConfiguration.class] 中定义的名称为“gatewayControllerEndpoint”的 bean 创建时出错：通过方法表示的不满足依赖项' gatewayControllerEndpoint'参数2； 嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException：在 class 路径资源 [org/springframework/cloud/gateway/config/GatewayAutoConfiguration.class] 中定义的名称为“weightCalculatorWebFilter”创建 bean 时出错：通过方法“weightCalculatorWebFilter”表示不满足的依赖关系参数0； 嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException：在 class 路径资源 [org/springframework/cloud/gateway/config/GatewayAutoConfiguration.class] 中定义名称为“gatewayConfigurationService”的 bean 创建时出错：通过方法“gatewayConfigurationService”表示不满足的依赖关系参数1； 嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有“org.springframework.core.convert.ConversionService”类型的合格 bean 可用：预计至少有 1 个有资格作为自动装配候选者的 bean。 依赖注解：{@org.springframework.beans.factory.annotation.Qualifier(value="webFluxConversionService")}

@SpringBootApplication
public class ServiceApplication {

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

    @Bean
    public MessageConverter messageConverter() {
        return new Jackson2JsonMessageConverter();
    }

    @Bean
    public ServerCodecConfigurer serverCodecConfigurer() {
        return ServerCodecConfigurer.create();
    }

}

Answer 1

尝试在 ServiceApplication class 中扩展SpringBootServletInitializer 。
