spring - How can I parse a property and inject values back into the Environment? -

-

i have property parse , inject values environment. make these values available using @value annotation.

eg. properties file or system property:

settings.compoundproperty=abc.xyz.123

i parse , inject 

prop1=abc prop2=xyz prop3=123

back environment. able inject these new properties in bean follows:

@value("${prop1}") prop1;  @value("${prop2}") prop2;

i tried this:

@configurationproperties (prefix="settings") public class environmentproperties {       @inject configurableenvironment env;        public void setcompoundproperty(string s) {            // parse s , inject prop1, prop2 , prop3 using env       }

however works if include 

@inject environmentproperties envprops;

in class @value("${prop1}") prop1; attributes.

how can without needing include envprops mentioned above ?

you can use spring expression language (spel)

all properties can accessed using environment in code below accessing prop1 , inject in value string

@value("#{environment.prop1}") private string value;
