Upgrade SpringCloud, SpringBoot and Alibaba versions

Preface

I have been using SpringCloud Hoxton.SR4 version and SpringBoot 2.2.5.RELEASE version. Since SpringCloud upgraded to 2020.0, I would like to try to upgrade, and record the problems encountered to share with you

Version comparison

There is a SpringCloud and SpringBoot comparison version official website. I upgraded it with reference to this version.


The following is to show the SpringCloud version comparison

The following is the Nacos corresponding SpringCloud and SpringBoot version comparison table :

So I chose the SpringCloud version is 2020.0.0 , SpringBoot version is 2.4.2 , Alibaba version is 2021.1 , here we come to the upgrade.

Problems encountered during the upgrade

• 1. Some dependent package versions have to be written dead, such as spring-cloud-starter-oauth2, because the spring-cloud-security-dependencies dependency is removed from cloud2020.0.0 and above.
• 2. Pom introduces the spring-cloud-starter-bootstrap package, otherwise bootstrap.yml will not work,
• 3. Add the service attribute to nacos discovery, otherwise an error will be reported, as shown below:

spring:
  application:
    name: aaa
  profiles:
    active: test
  cloud:
    nacos:
      discovery:
        server-addr: http://nacos-host:8848
        namespace: xxx-xxx-xxx
        service: aaa
      config:
        server-addr: http://nacos-host:8848
        file-extension: yaml
        prefix: aaa
        namespace: xxx-xxx-xxx
server:
  port: 8901

to sum up

• 1. The spring-cloud--starter-oauth2 package of the previous version is gone, and the corresponding one is not found. The reference packages spring-security-oauth2 and spring-security-oauth2-autoconfigure can also implement the oauth2 server function, but the related class prompts expire.
• 2. In the previous version, when spring cloud bus and mq were used together, it was impossible to use stream3.0 to receive messages. Now this problem has been solved.
• Except eureka, other netflix components have been deleted
