Question

Spring Boot Starter：2.1.4。发行

我正在尝试使用spring-cloud-starter-netflix-zuul在春季启动时设置服务代理，但是jar在启动过程中引发了以下异常

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

Description:

Field server in org.springframework.cloud.netflix.zuul.ZuulServerAutoConfiguration required a bean of type 'org.springframework.boot.autoconfigure.web.ServerProperties' that could not be found.

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


Action:

Consider defining a bean of type 'org.springframework.boot.autoconfigure.web.ServerProperties' in your configuration.

下面是我的主要

package com.xxx.serviceproxy;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.boot.WebApplicationType;
import org.springframework.boot.autoconfigure.web.ServerProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;

@Configuration
@ComponentScan
@EnableAutoConfiguration
@Controller
@EnableZuulProxy
@SpringBootApplication
public class ServiceProxyApplication {

    public static void main(String[] args) {
        new SpringApplicationBuilder(ServiceProxyApplication.class).web(WebApplicationType.NONE).run(args);
    }

}

之所以会发生这种情况，是因为您要添加注释 @EnableAutoConfiguration 。

此注释导致搜索类 ZuulServerAutoConfiguration 。

您可以在这里看到：

https://github.com/spring-cloud/spring-cloud-netflix/blob/master/spring-cloud-netflix-zuul/src/main/java/org/springframework/cloud/netflix/zuul/ZuulServerAutoConfiguration.java

具有从

自动连线的

@Autowired
protected ServerProperties server;

在类的标题中，您可以看到注释：

// Make sure to get the ServerProperties from the same place as a normal web app would
// FIXME @Import(ServerPropertiesAutoConfiguration.class)
public class ZuulServerAutoConfiguration {

这意味着它没有自动配置。

如果删除注释 @EnableAutoConfiguration ，它将不再寻找zuul自动配置，并且可以在application.yml（或application.properties）中配置zuul路径和其他功能，例如：< / p>

 zuul:
  routes:
    users:
      path: /myusers/**
      serviceId: users_service

这里是配置zuul的文档：

在Spring中执行Zuul代理时出现问题（找不到bean类型）
