Merge property file into application.properties-CodePudding

I have two properties files. Let's say a.properties and b.properties. these file values has been stored in maps created, let say aMap and bMap.

@PropertySource(value={ "classpath:a.properties", "classpath:b.properties"})
Class propFile{
   Private Map<String, String> aMap;
   Private Map<String, String> bMap;
}

I have to merge these property file into application.properties such that it works same way. Please provide me solution for this.

CodePudding user response：

You will be able to retrieve your properties by annotating your properties class with @Configuration and @ConfigurationProperties:

@Configuration
@ConfigurationProperties(prefix="maps")
public class ConfigProperties {
    private Map<String, String> a;
    private Map<String, String> b;

    // getters and setters
}

The corresponding application.yml would look as follows:

maps:
  a:
    key:
      test1
  b:
    key:
      test2

Or alternatively with an application.properties file:

maps.a.key=test1
maps.b.key=test2
