Spring Boot: Load @Value from YAML file

Question

I need to load a property from a .yml file, which contains the path to a folder where the application can read files from.

I\'m using the following code

Answer 1

In yml properties file :

xxxx:
     page:
        rowSize: 1000

Create your Yaml properties config class :

@Configuration
@EnableConfigurationProperties
@ConfigurationProperties(prefix = "xxxx")
public class YmlPropertiesConfig {

    private Page page;

    public Page getPage() {
        return page;
    }
    public void setPage(Page page) {
        this.page = page;
    }

    public class Page {
        private Integer rowSize;

        public Integer getRowSize() {
            return rowSize;
        }

        public void setRowSize(Integer rowSize) {
            this.rowSize = rowSize;
        }
    }    
}

Finally get it and use it :

public class XXXXController {

     @Autowired
     private YmlPropertiesConfig ymlProperties;

     public String getIt(){

        Integer pageRowSize = ymlProperties.getPage().getRowSize();
     }
}
