How to store properties into a Map

Question

I have a properties file like for example *.properties key1 = value1 key2 = value2

Is there way to store all the key value pairs in a hash map?

So you want all properties in a specific property file or from all property files? — awgtek, Sep 07 '21 at 18:42

If the question relates to the Spring framework, then you can create Configuration Beans based on a *.properties or *.yml files.

Example MyAppProperties.java

@Getter
@Setter
@FieldDefaults(level = AccessLevel.PRIVATE)
@Configuration
@ConfigurationProperties(prefix = "props")
public class MyAppProperties {
    Map<String, String> map = new HashMap<>();
}

And your properties that start with props.map.* will be available through this Configuration Bean, which can be obtained from the application context.

props.map.key1=value1
props.map.key2=value2
