Cherry :
Consider a code:
package com.hellokoding.springboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class WebApplication extends SpringBootServletInitializer {
@Bean
@ConditionalOnProperty(prefix = "config.prefix", name = "name", value = "SOMEVALUE", matchIfMissing = true)
public BeanOne beanOne() {
System.out.println("ok");
return new BeanOne();
}
@Bean
@ConditionalOnProperty(prefix = "config.prefix", name = "name", value = "OTHERVALUE")
public BeanTwo beanTwo() {
System.out.println("ok");
return new BeanTwo();
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(WebApplication.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(WebApplication.class, args);
}
}
Here is a git repo with code. When I start spring boot I got exception:

What is wrong??? Oo The property is present, syntax is pretty simple and looks like in examples...
P.S. All of this looks very strage, because a lot of spring boot configs have same ConditionalOnProperty with prefix and value, if there is a bug al of them would not work.
Darren Forsythe :
The value param is aliased by name leading to this error. i.e. they are effectively the same param.
You will want to swap value to havingValue
@ConditionalOnProperty(prefix = "config.prefix", name = "name", havingValue = "OTHERVALUE")
@ConditionalOnProperty(prefix = "config.prefix", name = "name", havingValue = "SOMEVALUE", matchIfMissing = true)
