I got the following error message when starting a spring boot/cloud application which gets some properties from consul:
***************************
APPLICATION FAILED TO START
***************************
Description:
Binding to target demo.config.Config@5b4954b2 failed:
Property: config.number
Value: ${config.number:5}
Reason: Failed to convert property value of type 'java.lang.String' to required type 'int' for property 'number'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [int]
Action:
Update your application's configuration
Here's my main class:
@SpringBootApplication
@WebAppConfiguration
@EnableDiscoveryClient
@EnableConfigurationProperties
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
And the configuration property class:
@Component
@ConfigurationProperties(prefix="config")
public class Config {
private int number;
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
}
The application.yml file is:
server:
port: 8100
spring:
application:
name: demo
And the bootstrap.yml file:
spring:
cloud:
consul:
host: localhost
port: 8500
config:
enabled: true
prefix: config
config:
number: ${config.number:5}
