Spring启动Eureka服务器项目无法启动

我刚刚创建了Spring Boot项目(使用Gradle Buildship 3.x),并在主类上启用了Eurekaserver。

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'traceFilterRegistration' defined in class path resource [org/springframework/cloud/netflix/eureka/server/EurekaServerAutoConfiguration.class]: Unsatisfied dependency expressed through method 'traceFilterRegistration' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.servlet.Filter' available: expected at least 1 bean which qualifies as autowire candidate.

build.gradle:

plugins {
    id 'org.springframework.boot' version '2.2.2.RELEASE'
    id 'io.spring.dependency-management' version '1.0.8.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'

    implementation('org.springframework.boot:spring-boot-starter-web')
compile group: 'org.springframework.cloud', name: 'spring-cloud-starter-netflix-eureka-server', version: '2.0.1.RELEASE'

}

test {
    useJUnitPlatform()
}

application.properties.Implement.Buildhip 3.x:

server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.client.service-url.defaultZone=http://localhost:8761/eureka

解决方案:

你遇到的问题已经被修复,在2019年5月13日,issue 春天-云计算-netflix

虽然这个问题在一年多前就已经解决了,但我最近还是遇到了。作为参考,作为变通方法,你可以添加缺失的bean。只有当spring cloud netfix没有提供时,才会创建。

@ConditionalOnMissingBean
@Bean
public HttpTraceRepository httpTraceRepository() {
   return new InMemoryHttpTraceRepository();
}

当我试图递增一个变量时,无法将变量与字典中的值进行比较。
