import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@ConfigurationProperties(prefix = "person")
public class QuickConfigurationAnnoController {
    
    private String name;
    private String address;
    private Integer age;

    @RequestMapping("/ConfigurationMethod")
    public @ResponseBody String firstMethod(){
    
        return "age:"+age+",name:"+name+",address: "+address;
    }

    public String getName() {
    
        return name;
    }

    public void setName(String name) {
    
        this.name = name;
    }

    public String getAddress() {
    
        return address;
    }

    public void setAddress(String address) {
    
        this.address = address;
    }

    public Integer getAge() {
    
        return age;
    }

    public void setAge(Integer age) {
    
        this.age = age;
    }
}

person:
  name:age: 22
  address:Hunan
