Overview

I tried to put the same configuration in bootstrap.yaml and application.yaml, and then get the configuration value through @Value. The result is the configuration in application.yaml. Normally, the priority of bootstrap.yaml should be I am surprised that it is greater than application.yaml, but in the process of debugging the code, I found that the priority of bootstrap.yaml is almost the lowest. I want to confirm why?

Environment

• Springboot 2.6.11
• SpringCloud 2021.0.4
• jdk 8

Detail

bootstrap.yaml

server:
  port: 30000
common: bootstrap.yaml

application.yaml

server:
  port: 30001
common: application.yaml

result

@SpringBootTest(classes = Main.class)
public class MainTest {
    private String commonValue;

    @Value("${common}")
    public void setCommonValue(String commonValue) {
        this.commonValue = commonValue;
    }

    @Test
    public void test() {
        System.out.println(commonValue);
        //output: application.yaml
    }
}

Question

Why does the configuration in application.yaml take precedence over bootstrap.yaml?

Support for bootstrap.yaml is a Spring Cloud feature. You may want to ask on Stack Overflow, or if you think you've found a bug, raise a Spring Cloud issue.
