Spring SpEL - Expression Language to create Map of String and Custom Object

Question

I\'m using Spring Boot example to read the following from the properties file.

sub.region.data={\\
    AF: {\'subRegionCd\' : \'34\', \'subR         


        

Answer 1

Looks like you made a mistake after 'subRegionDesc',, I think you mean using colon, not a comma here

With spring boot I suggest you to use ConfigurationProperties, instead of @Value.

For example, in this case you have to:

1. put @EnableConfigurationProperties(SubRegionConfig.class) to one of your spring configuration class.

2. Create config class:

   @ConfigurationProperties(prefix = "sub.region")
   public static class SubRegionConfig {
       private Map data;
       //getters and setters
   } 
   

3. Use .yml instead of .properties, like that:

   sub:
     region:
      data:
        AF:
         subRegionCd: '34'
         subRegionName: 'Southern Asia'
         subRegionDesc: ''
         subRegionStatus: 'A'
   

4. After that you can get every properties you want from SubRegionConfing

   @Autowired
   private SubRegionConfig subRegionConfig;
   

ConfigurationsProperties is more complex, but more flexible and preferrable to use in most cases.
