spring-boot - 找不到类型为 'com.netflix.discovery.AbstractDiscoveryClientOptionalArgs' 的 bean

Question

我正在尝试为我的微服务创建一个 Zuul Api 网关。它还具有 Eureka 发现客户端。

这是应用类

ZuulServerApplication.java

package com.ftr.zuul;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableZuulProxy
@EnableDiscoveryClient
public class ZuulServerApplication {

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

}

pom.xml配置

我在尝试运行应用程序时遇到以下错误。

***************************
APPLICATION FAILED TO START
***************************

Description:

Field optionalArgs in org.springframework.cloud.netflix.eureka.EurekaClientAutoConfiguration$RefreshableEurekaClientConfiguration required a bean of type 'com.netflix.discovery.AbstractDiscoveryClientOptionalArgs' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.netflix.discovery.AbstractDiscoveryClientOptionalArgs' in your configuration.

它在没有 Zuulserver 的情况下工作正常，但是当我添加 zuul 依赖项时，我得到了这个错误。如何解决这个问题？

Answer 1

到目前为止，恢复到 Spring Boot 2.7.7 是唯一对我有用的方法，所以如果您能够做到这一点，那么它可能是最简单的解决方案:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.7</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

不过，我意识到这不是一个很好的长期解决方案。如果我发现更好的东西，我会继续寻找并更新。
