Note the naming rules of Data ID

${prefix}-${spring.profile.active}.${file-extension}- The prefix defaults to the value of spring.application.name of the project configuration (ie: nacos-provider),It can also be configured through the configuration item spring.cloud.nacos.config.prefix.- spring.profiles.active=dev is the profile corresponding to the current environment.Note: When spring.profiles.active is empty,The corresponding connector - will also not exist, and the concatenation format of dataId becomes ${prefix}.${file-extension}- file-exetension is the data format of the configuration content, which can be configured through the configuration item spring.cloud.nacos.config.fileextension.Currently only properties and yaml types are supported.

The loading order of the springboot configuration file
This mainly describes the loading order of application and bootstrap.
bootstrap.yml (bootstrap.properties) loads
application.yml (application.properties) first
bootstrap.yml is used for the bootstrap phase of the application context.
bootstrap.yml is loaded by the parent Spring ApplicationContext.The parent ApplicationContext is loaded before using application.yml.
(2) Configuration difference Both bootstrap.yml and application.yml can be used to configure parameters.
bootstrap.yml can be understood as some parameter configurations at the system level, these parameters generally do not change.
application.yml can be used to define application level.

We use the bootstrap.yml configuration file in our project

#Configuration center addressspring:cloud:nacos:config:server-addr: 127.0.0.1:8848#spring.profiles.active=dev# This configuration affects the dataId in the unified configuration centerapplication:name:service-statistics# Namespaces#spring.cloud.nacos.config.namespace=8c7d4e34-09df-405f-a351-50fa42285a7f

Note that if bootstrap.yml is used locally, the configuration file in nacos must also be of the type yml or it will not be loaded. Similarly, if it is bootstrap.properties, the configuration file in nacos must also be properties or it will not be loaded.Load to, according to the suffix of dataId and the selection in the new configuration

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 also 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
