# Nacos Config Preference
|
||||
|
||||
## Project instruction
|
||||
|
||||
This project demonstrates how to use config preferences.
|
||||
|
||||
## Example
|
||||
|
||||
1. Start a Nacos server
|
||||
add configuration `test.yml`
|
||||
```yaml
|
||||
configdata:
|
||||
user:
|
||||
name: freeman
|
||||
```
|
||||
|
||||
add configuration `test2.yml`
|
||||
```yaml
|
||||
dev:
|
||||
age: 22
|
||||
```
|
||||
|
||||
2. Set configuration preference
|
||||
|
||||
Set default configuration preference
|
||||
```yaml
|
||||
spring:
|
||||
cloud:
|
||||
nacos:
|
||||
config:
|
||||
preference: remote
|
||||
```
|
||||
|
||||
Specify configuration (test 2.yml) to set configuration preference
|
||||
```yaml
|
||||
spring:
|
||||
config:
|
||||
import:
|
||||
- optional:nacos:test.yml
|
||||
- optional:nacos:test2.yml?preference=local
|
||||
```
|
||||
|
||||
3. Verify
|
||||
Access `localhost`, you should see the value of `freeman: 20`, because `name` uses the configuration center configuration first, and `age` uses the local configuration first.
