Solve the problem that the local nacos is not configured but the localhost8848 connection exception always occurs

Introduction

The thing is like this, the registration center nacos is configured for a project, and the nacos service of the local machine is configured at the beginning. After changing the nacos address to a virtual machine later, although the project is successfully started, it reports a nacos exception, as follows:

There are two configuration files:

Configured separately:

You can see that there is no configuration about localhost:8848 at all, but the exception of localhost:8848 is still reported. Open the nacos visualization interface of the virtual machine and find that the service has been registered in the nacos of the virtual machine

The version in question is:

com.alibaba.cloud spring-cloud-starter-alibaba-nacos-discovery 2.2.6.RELEASE com.alibaba.cloud spring-cloud-starter-alibaba-nacos-config 2.2.6.RELEASE

Resolve

This is caused when nacos reads its own automatic configuration with a higher priority than the configuration in the application file, and the automatic configuration of nacos itself is the nacos service on port 127.0.0.1:8848, so the above exception occurs, so it is necessary toRaise the priority of the configuration file

Create a bootstrap.properties or bootstrap.yml file to configure the nacos address.This configuration is system-level and has the highest priority. If you first read the nacos address from this file, no error will be reported

spring.cloud.nacos.server-addr=192.168.190.128:8848

Let me introduce myself first. The editor graduated from Shanghai Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Alibaba in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
