spring boot can not get configuration from application.yml - spring

Question

My spring boot application can not get configuration parameters from application.yml file. My main class as following:
#SpringBootApplication(scanBasePackages={"com.test"})
public class Main {
#Bean
public Validator validator(){
return new org.springframework.validation.beanvalidation.CustomValidatorBean();
}
public static void main(String[] args) throws IOException {
new SpringApplicationBuilder(Main.class)
.properties("application.yml")
.build()
.run(args);
}
}
My controller class as following:
#RestController
#RequestMapping("/test_traffic")
#Component
public class AnycastTrafficController {
#Autowired
TestService testService;
#GetMapping("/test")
public Object component() {
return testService.getTraffic();
}
}
My Service class as following:
#Service
public class TestService {
#Autowired
TestDao testDao;
public Object getTraffic() {
testDao.getTraff();
}
}
My Dao class as following:
#Component
public class TestDao {
#Autowired
MyDBConfig mydbConfig;
public DB getMyDBConfig () {
DB db = new DB(mydbConfig.id, mydbConfig.key);
return db;
}
}
My Config class as following:
#Configuration
#EnableConfigurationProperties
#ConfigurationProperties(prefix = "mydb")
public class MyDBConfig {
public String id;
public String key;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
}
My application.yml (which located at /src/main/resources)as following:
server:
port: 8003
context-path: /
logging:
level:
ROOT: INFO
org.springframework: INFO
org.springframework.data: INFO
com.alibaba: INFO
file: log/
docserver:
accessKeyId: 1111
accessKeySecret: 2222
---
spring:
profiles: dev
application:
name: test-application
mydb:
id: 1111111
key: 2222222
But when I started the Main class and request the url, it threw exception as following:
the id should not be empty.
that mean my Configuration class didn't get the configure data from yml file, so where I did wrong please. p.s(but the server port 8003 could be found by application). Thanks!

Answer 1

Your application.yml contains an invalid property option.
Instead of
spring:
profiles: dev
you should use
spring:
profiles:
active: dev
After correcting this this, the configuration processor should work properly.
