I'm new using Spring framework and also Velocity, because that I wanna apologize if I'm missing something basic.
When I try to do something like this:
#Override
public void envia(final Usuario usuario) {
// TODO Auto-generated method stub
MimeMessagePreparator preparator = new MimeMessagePreparator() {
public void prepare(MimeMessage mimeMessage) throws Exception {
MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
message.setTo(usuario.getEmail());
message.setFrom("pirado2#gmail.com"); // could be parameterized...
Map model = new HashMap();
model.put("user", usuario);
String text = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine,
"/templates/registration-confirmation.vm",
"UTF-8",
model);
message.setText(text, true);
}
};
this.mailSender.send(preparator);
}
I get this error:
ERROR [VelocityEngine ] ResourceManager : unable to find resource '/templates/registration-confirmation.vm' in any resource loader.
How can I find my vm file though ?
thanks.

I want to load the values from json file upon the Spring Boot Application is started.
My code for the Configuration File is like the below:
#Configuration
#Getter
public class FedexAPIConfig {
private final static String JSON_FILE = "/static/config/fedex-api-credentials.json";
private final boolean IS_PRODUCTION = false;
private FedexAPICred apiCredentials;
public FedexAPIConfig() {
try (InputStream in = getClass().getResourceAsStream(JSON_FILE);
BufferedReader reader = new BufferedReader(new InputStreamReader(in, StandardCharsets.UTF_8))) {
JSONObject json = new JSONObject();
// this.apiCredentials = new JSONObject(new JSONTokener(reader));
if (IS_PRODUCTION) {
json = new JSONObject(new JSONTokener(reader)).getJSONObject("production");
} else {
json = new JSONObject(new JSONTokener(reader)).getJSONObject("test");
}
System.out.println(json.toString());
this.apiCredentials = FedexAPICred.builder()
.url(json.optString("url"))
.apiKey(json.optString("api_key"))
.secretKey(json.optString("secret_key"))
.build();
} catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
and with this, when the application is in progress of startup, values are successfully printed on the console.Startup console log
When I tried to call this value from other ordinary class, like the below:, it brings nothing but just throws NullPointerException... What are my faults and what shall I do?
public class FedexOAuthTokenManager extends OAuthToken {
private static final String VALIDATE_TOKEN_URL = "/oauth/token";
private static final String GRANT_TYPE_CLIENT = "client_credentials";
private static final String GRANT_TYPE_CSP = "csp_credentials";
#Autowired
private FedexAPIConfig fedexApiConfig;
#Autowired
private Token token;
#Override
public void validateToken() {
// This is the part where "fedexApiConfig" is null.
FedexAPICred fedexApiCred = fedexApiConfig.getApiCredentials();
Response response = null;
try {
RequestBody body = new FormBody.Builder()
.add("grant_type", GRANT_TYPE_CLIENT)
.add("client_id", fedexApiCred.getApiKey())
.add("client_secret", fedexApiCred.getSecretKey())
.build();
response = new HttpClient().post(fedexApiCred.getUrl() + VALIDATE_TOKEN_URL, body);
if (response.code() == 200) {
JSONObject json = new JSONObject(response.body().string());
token.setAccessToken(json.optString("access_token"));
token.setTokenType(json.optString("token_type"));
token.setExpiredIn(json.optInt("expires_in"));
token.setExpiredDateTime(LocalDateTime.now().plusSeconds(json.optInt("expires_in")));
token.setScope(json.optString("scope"));
}
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
}
fedexApiConfg is null even though I autowired it in prior to call.
And this FedexOAuthTokenManager is called from other #Component class by new FedexOAuthTokenManager()
Did you try like below?
Step 1: Create one Configuration class like below
public class DemoConfig implements ApplicationListener<ApplicationPreparedEvent> {
#Override
public void onApplicationEvent(ApplicationPreparedEvent event) {
//Load the values from the JSON file and populate the application
//properties dynamically
ConfigurableEnvironment environment = event.getApplicationContext().getEnvironment();
Properties props = new Properties();
props.put("spring.datasource.url", "<my value>");
//Add more properties
environment.getPropertySources().addFirst(new PropertiesPropertySource("myProps", props));
}
To listen to a context event, a bean should implement the ApplicationListener interface which has just one method onApplicationEvent().The ApplicationPreparedEvent is invoked very early in the lifecycle of the application
Step 2: Customize in src/main/resources/META-INF/spring.factories
org.springframework.context.ApplicationListener=com.example.demo.DemoConfig
Step 3: #Value in spring boot is commonly used to inject the configuration values into the spring boot application. Access the properties as per your wish.
#Value("${spring.datasource.url}")
private String valueFromJSon;
Try this sample first in your local machine and then modify your changes accordingly.

How to implement PayUmonney in Android & how to create a Hash key in local because I don't know how to create in server
In my app I m sending 3 parameters to server latitude,longitude and image.Earlier i was using volley for sending the parameter, but since i have a image also I had to use Multipart in my code.But i m getting an error while uploadind. In the notification bar the uploading starts but after some times it says error in uploading
Below is the code for MultiPart:
public void send() {
try {
String uploadId = UUID.randomUUID().toString();
//Creating a multi part request
new MultipartUploadRequest(this, uploadId, REGISTER_URL)
.setMethod("POST")
.addParameter("action", "location")
.addFileToUpload(imagePath, "data")//Adding file
//.addParameter("name", name) //Adding text parameter to the request
.setNotificationConfig(new UploadNotificationConfig())
.setMaxRetries(5)
.startUpload(); //Starting the upload
} catch (Exception exc) {
Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show();
}
}
Below is my volley code:
final String latitudee = String.valueOf(latitude);
final String longitudee =String.valueOf(longitude);
final String datae = imagePath;
//getting the actual path of the image
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(MapsActivity.this,response,Toast.LENGTH_LONG).show();
System.out.println(response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MapsActivity.this,error.toString(),Toast.LENGTH_LONG).show();
}
}){
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("action","location");
params.put("latitude",latitudee);
params.put("longitude",longitudee);
send();
// params.put("data", datae);
//Uploading code
return params;}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
Please help me where I'm going wrong
You can send your others parameters through Multipart request library too. just add "add parameter" to send more parameters.
I've searched and got the solution for adding CDATA tag for Axstream, and it worked well in Eclipse in my machine. However, after I deployed my code to tomcat server, it always failed with IOException at toXML(t, writer) or toXML(t), I've also tried to make the writer to "UTF-8", but still no luck.
My code for handle CDATA is:
XStream xstream = new XStream( new XppDriver(){
#Override
public HierarchicalStreamWriter createWriter(Writer out) {
return new PrettyPrintWriter(out){
boolean cdata = false;
#Override
public void startNode(String name) {
super.startNode(name);
cdata = name.equalsIgnoreCase("imagestream");
}
#Override
protected void writeText(QuickWriter writer, String text) {
if(cdata && !text.isEmpty()){
writer.write("<![CDATA[");
writer.write(text);
writer.write("]]>");
}else {
writer.write(text);
}
}
};
}
});
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
PrintWriter writer = new PrintWriter(new OutputStreamWriter(outputStream, Charset.forName("UTF-8")));
xstream.toXML(t,writer);
xml = outputStream.toString("UTF-8");
In my android test application, after that i got the JSON file from the Google Developer Console, where i had set on the Gmail API, and that i have put it in the emulator, i get an IOException which says:
"com.google.api.client.googleapis.json.GoogleJsonResponseException:
403 Forbidden { "code" : 403, "errors" : [ {
"domain" : "usageLimits",
"message" : "Access Not Configured. Please use Google Developers Console to activate the API for your project.",
"reason" : "accessNotConfigured" } ], "message" : "Access Not Configured. Please use Google Developers Console to activate the API
for your project." }"
I think that I must use a GoogleClientSecrets object, but i haven't found its use.
Here the code:
public class MainActivity extends Activity
{
final String SCOPE = "oauth2:https://www.googleapis.com/auth/gmail.compose";
final String FILE_NAME = "TestEmail5.json";

You need to login to http://console.developers.google.com/ and create a project and activate the "Gmail" API for it.
