I try to develop an aplication that just has to send a email with an image.
I saw some solutions that refer configuring the following property
<property name="viewNames" value="templates/*, pages/*" />
but I dont know how I have to configure in java way, thus this way doesnt works:
thymeleaf.setViewNames("templates/*"),
However, it is appearing an error message:

I am developing a REST API with Spring MVC.
And it builds successfully, but when I try to deploy it to Tomcat 8.0.57
it gives the following error saying I have already a bean method in that controller. But I dont have any two methods with same names or RequestMethod.

And these are the Controllers.
ChatUserController
#RestController
public class ChatUserController {
// Store the Users temporarily
ArrayList<User> users = new ArrayList<>();
// Get all the online users
#RequestMapping(name = "/users/", method = RequestMethod.GET)
public ArrayList<User> getUsers(){
users.add(new User("Janith","Hellow worlds"));
return users;
}
// Save new user / User Login
#RequestMapping(name = "/users/",method = RequestMethod.POST)
public String saveUser(#RequestBody User user){
if(user != null){
users.add(user);
return "Successfull Saved";
}else{
return "Failed";
}
}
// Remove the user / User sign out
#RequestMapping(name = "/users/{uname}", method = RequestMethod.DELETE)
public String deleteUser(#PathVariable String uname){
for(User u:users){
if(u.getUsername().equals(uname)){
users.remove(u);
return "Removed Successfully";
}
}
return "User Not found. Should be already Deleted.";
}
}
ChatMessagesController
#RestController
public class ChatMessageController {
ArrayList<Message> messagesList = new ArrayList<>();
#RequestMapping(name = "/messages/{username}", method = RequestMethod.PUT)
public ArrayList<Message> getChat(#PathVariable String username) {
// create a new list of unread messages
ArrayList<Message> myMessages = new ArrayList<>();
// add the unread messages to list
for (Message m : messagesList) {
if (m.getReciever().equals(username)) {
if (!m.isViewed()) {
m.setViewed(true);
myMessages.add(m);
}
}
}
return myMessages;
}
#RequestMapping(name = "/messages/", method = RequestMethod.POST)
public Integer saveMessage(#RequestBody Message message){
if(message != null){
message.setViewed(false);
messagesList.add(message);
return new Integer(1);
}else{
return new Integer(0);
}
}
}
But this ChatUserController worked fine, I deployed and tested it.
This error is getting after adding the ChatMessageController's second method saveMessage(). And also this same error showed when the first method getChat() was in GET RequestMethod. It was fixed after I changed it to the PUT method.
I am new to Spring MVC Web API, So I appreciate any help regarding this.
In my case I go to read Spring doc to find some explanation but I finished when found this in RequestMapping interface:
Note: This annotation can be used both at the class and at the method level. In most cases, at the method level applications will prefer to use one of the HTTP method specific variants #GetMapping, #PostMapping, #PutMapping, #DeleteMapping, or #PatchMapping.
So I decided also to prefer to use #GetMapping, #PostMapping, #PutMapping, #DeleteMapping, or #PatchMapping and it works in my case.
Try to make:
#GetMapping("/users/")
public String saveUser(#RequestBody User user){
//...
}
#DeleteMapping("/users/{uname}")
public String deleteUser(#PathVariable String uname){
//...
}
P.S: also we need use value if we need set path:
#RequestMapping(value = "/users/", method = RequestMethod.GET)
name its only name, not path
I am trying to implement simple fileupload using Spring 4.2.3 and HTML form.
I have controller class which handles whole action, simple wrapper class for file, validator and simple view with form in HTML & Thymeleaf.
Almost everything is running fine, mapping works properly and view is appearing. But when I select file from disk and press upload button I have NullPointerException. Can anyone have a look and give some tips please? I have to mention that I am novice in Spring.
Controller:
#Controller
public class FileUploadController {
private static String UPLOAD_LOCATION = "C:/Temp/";
#Autowired
FileValidator fileValidator;
#InitBinder("file")
protected void initBinderFileBucket(WebDataBinder binder) {
binder.setValidator(fileValidator);
}
#RequestMapping(value = "/upload", method = RequestMethod.GET)
public String getSingleUploadPage(ModelMap model) {
FileBucket fileModel = new FileBucket();
model.addAttribute("fileBucket", fileModel);
return "views/fileUploader";
}
#RequestMapping(value = "/upload", method = RequestMethod.POST)
public String singleFileUpload(#Valid FileBucket file, BindingResult result, ModelMap model)
throws IOException {
if (result.hasErrors()) {
System.out.println("File Uploader validation error");
return "views/fileUploader";
} else {
System.out.println("Fetching file"); //prints out in console
MultipartFile multipartFile = file.getFile();
System.out.println(multipartFile.getName()); //NullPointer here
return "views/success";
}
}
}
File wrapper:
public class FileBucket {
private MultipartFile file;
//getters & setters + soon other stuff
}
Validator:
#Component
public class FileValidator implements Validator {
public boolean supports(Class<?> clazz) {
return FileBucket.class.isAssignableFrom(clazz);
}
public void validate(Object obj, Errors errors) {
FileBucket file = (FileBucket) obj;
if(file.getFile()!=null){
if (file.getFile().getSize() == 0) {
errors.rejectValue("file", "missingfile");
}
}
}
}

Okay I found out what's causing the problem.
After correcting name in #InitBinder to match argument in controller it was necessary to rename bean responsible for multipart resolving.
From:
#Bean public CommonsMultipartResolver commonsMultipartResolver() {
return new CommonsMultipartResolver();
}
To:
#Bean public CommonsMultipartResolver multipartResolver() {
return new CommonsMultipartResolver();
}
Otherwise it doesn't work.
I have experienced this strange error, and now I will explain when this happens:
basically what I have to do is having an HTML form (or JSP, doesn't really matter) with a simple textfield and two buttons, one for submitting to the .jsp page and the other one is just to reset the textfield.
Everything is working fine, except when I try to write in the textfield something with spaces (example: "abc 123").
If I simply write "abc123" it doesn't give any error 500 though.
I hope some of you can help me, here are the sources:
<html>
<head>`<html>

<meta charset="ISO-8859-1">
<title>HTML Form</title>
</head>

This is the method showContent with it's called methods:
public static String showContent() throws Exception {
if (isFood())
return getContent();
else
return "LOG Creato: " + generateLogFile();
}
private static String generateLogFile() throws Exception {
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
String logname = "foodLog_" + sdf.format(cal.getTime());
String logdir = ps.getProperty("logfolder");
File f = new File ("." + logdir + logname + ".log");
FileOutputStream fout = new FileOutputStream(f);
DataOutputStream dout = new DataOutputStream(fout);
System.out.println(logname);
System.out.println(logdir);
System.out.println(f.getParent());
dout.writeBytes(food + " non esistente, si prega di aggiungerlo");
fout.close();
return logname;
}
private static String getContent() {
String result = "{[";
#SuppressWarnings("resource")
Scanner sc = new Scanner(inputReader).useDelimiter("\\A");
result += sc.hasNext() ? sc.next() : "";
return result;
}
I solved:
showContent() throws an Exception, and I only need to catch that.
The error was caused because I used to throw a new exception in the try-catch of showContent(), something I couldn't do for the reason above.
Thanks everybody.
I have a problem with my MVC server. When I post my JSON:
{
"shipName":"shfdsfds",
"signal":"fdsfsd321",
"longitude":43,
"latitude":32,
"maxSpeed":342
}
using PUT method and in Signal class two constructors is defined:
public Signal(){
}
public Signal(String shipName, String signal, int latitude, int longitude,
int maxSpeed) {
ShipName = shipName;
Signal = signal;
Latitude = latitude;
Longitude = longitude;
MaxSpeed = maxSpeed;
}
everytime I receive Status Code: 200-Ok, but wrong value of prams (addSignal: 0).
My controler:
#RequestMapping(value = "/addSignal", method = RequestMethod.PUT)
#ModelAttribute
public ResponseEntity<Signal> add(
#ModelAttribute Signal signal) throws SQLException,
ClassNotFoundException {
System.out.println("addSignal: "+signal.getMaxSpeed());
return new ResponseEntity<Signal>(signal, HttpStatus.OK);
}
When I try remove the first constructor (public Signal(){}), I receive error:
Status Code: 500 Internal Server Error

---------edit---------
I have changed my controller:
#RequestMapping(value = "/addSignal", method = RequestMethod.PUT, produces = "application/json")
public ResponseEntity<Signal> add(
#RequestBody Signal signal) throws SQLException,
ClassNotFoundException {
System.out.println("addSignal: "+signal.getMaxSpeed());
return new ResponseEntity<Signal>(signal, HttpStatus.OK);
}
In Signal class now I have one constructor:
public Signal(#JsonProperty("shipName")String shipName,#JsonProperty("signal")String signal,
#JsonProperty("latitude")int latitude, #JsonProperty("longitude")int longitude,
#JsonProperty("maxSpeed")int maxSpeed) {
ShipName = shipName;
Signal = signal;
Latitude = latitude;
Longitude = longitude;
MaxSpeed = maxSpeed;
}
Sending Json by RESTClient I add header:Content-Type:application/json.
Now I receive error:
HTTP Status 415
In my console nothing appears.
I feel like you should use #RequestBody instead of #ModelAttribute.
And to be sure that json deserializer correctly constructs your class using json data i suggest annotating constructor parameters with #JsonProperty("propertyName") where propertyName matches json property name.
---edit---
Are you sure that you correctly set header? Because your code works fine for me.
The full error: java.lang.NoClassDefFoundError: Could not initialize class lt.maze.dao.DAO
The class DAO is used from my LoginServlet. It is compiled and deployed, I checked WEB-INF/classes. DAO.class exists.
Why is isn't it loaded? Am I suppose to add them to my classpath manually? (I have the manifest file to load my properties file).
LoginServlet.java:
#WebServlet(name = "LoginServlet", urlPatterns = { "/login" })
public class LoginServlet extends HttpServlet {
#Override
public void init() throws ServletException
{
System.out.println("System. out. Its online.");
getServletContext().log("LoginServlet initialised");
}
#Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
getServletContext().log("Http request. Request URI: " + request.getRequestURI());
System.out.println("Http request. Request URI: " + request.getRequestURI());
String username = request.getParameter("username");
String password = request.getParameter("password");
if(username == null || password == null) {
response.sendError(401);
} else {
UserDAO userDAO = DAO.getUserDAO();
User user = userDAO.find(username, password);
if(user == null) {
response.sendError(401, "Invalid username or password");
} else {
String sessionToken = SessionTokens.getSessionToken();
response.addCookie(new Cookie("session-token", sessionToken));
getServletContext().log("Valid connection. token:"+sessionToken);
}
}
}
#Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
getServletContext().log("Request received via GET.");
System.out.println("Requeswt received via GET");
}
