Could not resolve placeholder 'XXXX' in value "YYY"

  1. I am unable to read my application.properties file.Here is my code for application.properties:

    eth.network.url="https://rinkeby.infura.io/v3/9ea96ecdf13c4756a99c19f4f34e679e";
    WORKING_DIRECTORY= "~/testnet-keystore/UTC--2018-10-08T16-17-25.818111000Z--8a69dcd0dbaf0f076d663f366ec0bffad9a3cf2a.json";
    WALLET_CREDENTIALS="*****";


    I am trying to use it in my java file:

    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.web3j.crypto.Credentials;
    import org.web3j.crypto.WalletUtils;
    import org.web3j.protocol.Web3j;
    import org.web3j.protocol.http.HttpService;


    @RestController

    public class DeployController {
    private Web3j web3j;
    private Credentials credentials;
    public ProofOfExistence contract;



    @Value("${eth.network.url}")
    private String NETWORK_URL;

    @Value("${WORKING_DIRECTORY}")
    private String WORKING_DIRECTORY;

    @Value("${WALLET_CREDENTIALS}")
    private String WALLET_CREDENTIALS;

    @RequestMapping("/DeployController")
    public String BlogControllerDemo() throws Exception{

    web3j = Web3j.build(new HttpService(NETWORK_URL));
    credentials = WalletUtils.loadCredentials(WALLET_CREDENTIALS, WORKING_DIRECTORY);
    contract = ProofOfExistence.deploy(web3j, credentials, ProofOfExistence.GAS_PRICE,ProofOfExistence.GAS_LIMIT).send();
    String addr = contract.getContractAddress();
    return addr;


    }

    }


    When i run the above code it says:
