I am trying to integrate spring vault as an extra module in my web application. I have created a new service EncryptionService which makes a call to my Spring Vault ApiVaultClient as it is shown bellow :
My Vault configuration VaultConfig.java :
package com.myproject.encryption;
import java.io.IOException;
import java.io.InputStream;
import java.net.URI;
import java.net.URISyntaxException;
import java.util.Properties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.vault.authentication.ClientAuthentication;
import org.springframework.vault.authentication.TokenAuthentication;
import org.springframework.vault.client.VaultEndpoint;
import org.springframework.vault.config.AbstractVaultConfiguration;
import org.springframework.vault.core.VaultTemplate;
@Configuration
public class VaultConfig extends AbstractVaultConfiguration {
private Properties props;
private String token;
private String host;
private int port;
public VaultConfig() {
this.props = new Properties();
InputStream vaultConfig = this.getClass().getClassLoader().getResourceAsStream("vault-config.properties");
if(vaultConfig!=null) {
try {
props.load(vaultConfig);
} catch (IOException ex) {
//LOG.error(ex.getMessage());
}
} else {
//LOG.error(new FileNotFoundException("property file vault-config.properties not found in the classpath"));
}
this.token = props.getProperty("vault.token");
this.host = props.getProperty("vault.uri");
}
@Override
public ClientAuthentication clientAuthentication() {
return new TokenAuthentication(this.token);
}
@Override
public VaultEndpoint vaultEndpoint() {
VaultEndpoint endpoint = null;
try {
endpoint = VaultEndpoint.from(new URI(this.host));
} catch (URISyntaxException ex) {
//LOG.error(ex.getMessage());
}
return endpoint;
}
/*I added this method hoping that this might solve the bean creation problem of vaultOperations in ApiVaultClient but it didn't work out either*/
@Bean
public VaultTemplate getVaultTemplate() {
VaultTemplate vaultTemplate = new VaultTemplate(vaultEndpoint(), clientAuthentication());
return vaultTemplate;
}
/**
* Setters & Getters
*/
public Properties getProps() {
return props;
}
public void setProps(Properties props) {
this.props = props;
}
public String getToken() {
return token;
}
public void setToken(String token) {
this.token = token;
}
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public int getPort() {
return port;
}
public void setPort(int port) {
this.port = port;
}
}
My REST Client ApiVaultClient.java :
package com.myproject.encryption;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
import javax.annotation.PostConstruct;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.vault.core.VaultOperations;
import org.springframework.vault.core.VaultTransitOperations;
@Component("apiVaultClient")
public class ApiVaultClient{
@Autowired
private VaultOperations vaultOperations;
private VaultTransitOperations transitOperations;
private String keyStore;
private Properties props;
@PostConstruct
public void init() {
this.transitOperations = vaultOperations.opsForTransit();
InputStream vaultConfig = this.getClass().getClassLoader().getResourceAsStream("vault-config.properties");
this.props = new Properties();
if(vaultConfig!=null) {
try {
props.load(vaultConfig);
} catch (IOException ex) {
//LOG.error(ex.getMessage());
}
} else {
//LOG.error(new FileNotFoundException("property file vault-config.properties not found in the classpath"));
}
this.keyStore = props.getProperty("vault.key.store");
}
public String encrypt(String clearText) {
String cipherText = transitOperations.encrypt(this.keyStore, clearText);
return cipherText;
}
public String decrypt(String cipherText) {
String clearText = transitOperations.decrypt(this.keyStore, cipherText);
return clearText;
}
public String getKeyStore() {
return keyStore;
}
public void setKeyStore(String keyStore) {
this.keyStore = keyStore;
}
public VaultOperations getVaultOperations() {
return vaultOperations;
}
public void setVaultOperations(VaultOperations vaultOperations) {
this.vaultOperations = vaultOperations;
}
public VaultTransitOperations getTransitOperations() {
return transitOperations;
}
public void setTransitOperations(VaultTransitOperations transitOperations) {
this.transitOperations = transitOperations;
}
public Properties getProps() {
return props;
}
public void setProps(Properties props) {
this.props = props;
}
}
My EncryptionService implementation :
package com.myproject.business.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import com.myproject.business.service.EncryptionService;
import com.myproject.encryption.ApiVaultClient;
public class EncryptionServiceImpl implements EncryptionService{
@Autowired
private ApiVaultClient apiVaultClient;
@Override
public String encrypt(String clearText) {
return apiVaultClient.encrypt(clearText);
}
@Override
public String decrypt(String cipherText) {
return apiVaultClient.decrypt(cipherText);
}
public ApiVaultClient getApiVaultClient() {
return apiVaultClient;
}
public void setApiVaultClient(ApiVaultClient apiVaultClient) {
this.apiVaultClient = apiVaultClient;
}
}
My vault-config.properties :
vault.uri=http://127.0.0.1:8200
vault.token=s.ty3r7is9tSlXfC4GFMHvwDa5
vault.key.store=transit/keys/store
My serviceContext.xml which lies in my business module :

When starting my application I get the following error :

I tried to follow what most tutorials propose by the book but in vain. Any help will be more than appreciated.
