1.展示一下異常(nacos中已經(jīng)配置spring.main.allow-bean-definition-overriding=true依然報(bào)錯(cuò))

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

APPLICATION FAILED TO START

Description:

The bean 'team-chat.FeignClientSpecification' could not be registered. A bean with that name has already been defined and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

2.解決方案:

spring.main.allow-bean-definition-overriding=true放置到配置nacos的配置文件中

舉例: 項(xiàng)目的環(huán)境有(本地,開(kāi)發(fā),測(cè)試,生產(chǎn))

分別是: bootstrap-local.yml、bootstrap-dev.yml、bootstrap-test.yml、bootstrap-prod.yml

bootstrap-dev.yml的nacos配置如下:

spring:
  application:
    name: team-talk #服務(wù)名稱(chēng)
  main:
    allow-bean-definition-overriding: true #當(dāng)遇到同樣名字的時(shí)候，是否允許覆蓋注冊(cè)
  cloud:
    nacos:
      discovery:
        server-addr:***.mse.aliyuncs.com:8848,6443,9848
      config: # 拉取配置中心需要改成application配置文件，優(yōu)先加載
        file-extension: yaml # 配置文件格式
        group: TEAM_GROUP
        server-addr: ***.mse.aliyuncs.com:8848,6443,9848
        enable-remote-sync-config: true

測(cè)試環(huán)境和生產(chǎn)環(huán)境都是同樣的配置,spring.main.allow-bean-definition-overriding=true不放置在nacos配置中心中.
