Spring Manual binding Configurationproperties

A typical application of spring loaded configurationproperties is auto-load (autowired), which requires manual modification of the loaded property properties in some special scenarios.

Code instance, config class

Importjava.util.ArrayList;Importjava.util.List;Importorg.springframework.boot.context.properties.ConfigurationProperties; @ConfigurationProperties (prefix= "Devices") Public classDeviceconfig {Privatelist<string> Imports =NewArraylist<string>(); Privatelist<devicedetailsproperties> definitions =NewArraylist<devicedetailsproperties>();  PublicList<string>Getimports () {return  This. Imports; }     PublicList<devicedetailsproperties>getdefinitions () {returndefinitions; }     Public voidSetimports (list<string>imports) {         This. Imports =imports; }     Public voidSetdefinitions (list<devicedetailsproperties>definitions) {         This. Definitions =definitions; }}

Deviceconfig class code used to Devicedetailsproperties, test demo only ID

 Public class devicedetailsproperties {    String id;      Public String getId () {        return  ID;    }      Public void setId (String id) {        this. ID= id;    }    @Override    public  String toString () {        return  ID;    }}

Test code Class

Importjava.util.Properties;Importorg.springframework.boot.bind.PropertiesConfigurationFactory; Public classTest { Public Static voidMain (string[] args)throwsException {Properties props=NewProperties (); Props.put ("Devices.imports[0]", "IMP1"); Props.put ("Devices.imports[1]", "IMP2"); Props.put ("Devices.definitions[0].id", "first"); Props.put ("Devices.definitions[1].id", "second"); Deviceconfig conf=NewDeviceconfig (); Propertiesconfigurationfactory<DeviceConfig> PCF =NewPropertiesconfigurationfactory<deviceconfig>(conf);        Pcf.setproperties (props); Pcf.settargetname ("Devices"); Conf=Pcf.getobject ();        System.out.println (Conf.getimports ());    System.out.println (Conf.getdefinitions ()); }}
