Your exception shows a NullPointerException on line 47 of BetController. However there is nothing at this line in the class you posted. My guess is that your UserService is not injected in your controller. Add the #Autowired annotation:
#Controller
public class BetController {
#Autowired
UserService service;

I think you miss autowire Userservice object in to controller layer
Please add #autowire top of Userservice object It will sovles your problem.
#Autowire
UserService service;
If its give any problem just google how to autowire service object,
Also you have done one mistake while creating service object you need to create Userservice as Interface and one concert implementation of Userservice like UserServiceImpl
Thanks,
Himanshu

Put #Service annotation on UserService class,and #Autowired on the below line in BetController class.
#Autowired
UserService service;
And i see you setted component scanning to controller package only,how ever you need to set it to below.
<context:component-scan base-package="org.proffart.bet.*"/>

This is the best example for Spring mvc crud operation using JQuery Ajax. You may find maven as well in this.

Root Cause

** Two reasons for this issue were:**
This was happening because Hibernate was generating HT_Alien table which is a temporary table and the reason behind this was the Hibernate-core version 6.0.0.Alpha3.
I had no default constructor in the Alien(Entity) class
Suggestion:
Guys, please use hibernate core version 5.4.1.Final while using ORM using Hibernate. Below is the dependency for the same:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.4.1.Final</version>
</dependency>
The issue is resolved now!!

Dependency injection Spring

I am building a web application using spring MVC which is connected to the database. This is part of my bean config file.
<!-- Define Database DataSource / connection pool -->

As you can see my data source is defined in a hard way. In code I am using #Autowired annotation to inject sessionFactory. But I would like to inject sessionFactory (jdbc, username, password etc.) with data which I will obtain from user during run time. For example he will write me those data to the textfeild and then I will create sessionFactory (based on his data) which will be connected to his database.
I was looking for an answer but unluckily I have not found anything that would fit to this problem.

There are multiple ways that spring bean definition can be changed in run time. One way is to refresh the Spring Application Context in run time which would have the bean definition specific to the functionality rather than all bean definition.
((ConfigurableApplicationContext)applicationContext).refresh();
Let me explain using one simple use case:
Create a PropertyBean which will load value from external properties file.
Create PropertiesApplicationContext which would have only PropertyBean definition config rather than all beans belongs the application.
Use ConfigurableApplicationContext refresh() method to reload ProperiesBean definition in run time.
More details about below example code snippet:
Web Application should display a Property Value from a bean which
will read the value from a external property file.
Property value will change anytime in external properties file.
Web Application should not restarted.
Here, bean definition should be changed in run time.
Spring Boot Application Code:
#SpringBootApplication(scanBasePackages = {"vijay.controller","vijay.configuration"})
public class SpringContextRefreshApplication extends SpringBootServletInitializer{
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(SpringContextRefreshApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(SpringContextRefreshApplication.class, args);
}
}
MVC Configuration:

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

resolver.setPrefix("/WEB-INF/view/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
registry.viewResolver(resolver);

import org.springframework.context.support.ClassPathXmlApplicationContext;
/**

public class PropertyApplicationContext implements ApplicationContextAware{
private ApplicationContext applicationContext;
private static PropertyApplicationContext propertyApplicationContext;
private PropertyApplicationContext(){
applicationContext = new ClassPathXmlApplicationContext("property-config.xml");
}
#Override
public void setApplicationContext(ApplicationContext ac) throws BeansException {
if(applicationContext == null){
this.applicationContext = ac;
}
}
public ApplicationContext getApplicationContext(){
return applicationContext;
}
public static PropertyApplicationContext getInstance(){
if(propertyApplicationContext == null){
propertyApplicationContext = new PropertyApplicationContext();
}
return propertyApplicationContext;
}
}
MVC Controller:
package vijay.controller;
import vijay.beans.PropertyDto;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import vijay.configuration.PropertyApplicationContext;
/**

* #author Vijay
*/
#Controller
public class PropertyController {
#RequestMapping("/")
public String testController(){
System.out.println("vijay.controller.PropertyController.testController()");
return "sample";
}
#RequestMapping(path = "/getProperties")
public String testPropertiesController(ModelMap modelMap){
ApplicationContext applicationContext = PropertyApplicationContext.getInstance().getApplicationContext();
PropertyDto propertyDto = (PropertyDto) applicationContext.getBean("propertyBean");
System.out.println("vijay.controller.PropertyController.testPropertiesController() " + propertyDto);
modelMap.addAttribute("message", propertyDto.getKey());
return "sample";
}
/**
* Method will refresh ApplicationContext
* #param modelMap as ModelMap
* #return viewName as String
*/
#RequestMapping(path = "/refreshProperties")
public String refreshBean(ModelMap modelMap){
ApplicationContext applicationContext = PropertyApplicationContext.getInstance().getApplicationContext();
// Refresh Application Context
((ConfigurableApplicationContext)applicationContext).refresh();
PropertyDto propertyDto = (PropertyDto) applicationContext.getBean("propertyBean");
System.out.println("vijay.controller.PropertyController.refreshBean()" + propertyDto);
modelMap.addAttribute("message", propertyDto.getKey());
return "sample";
}
}

Here, MVC Controller has /refreshProperties which will refresh the PropertiesBean defined in PropertiesApplicationContext. As properties-config.xml the only bean definition defined in PropertiesApplicationContext, propertiesBean alone will be refreshed and no other bean definition will be refreshed.
Similar way, you can create Application Context by extending ApplicationContextAware which will have bean definition of sessionFactory. You can get SessionFactory wherever required from this context and refresh the context wherever required.
This is one way to achieve the bean definition change in run time.

Did you try this [Change SessionFactory datasource jdbcurl late in runtime] (Change SessionFactory datasource jdbcurl late in runtime)?

Spring MVC + Thymeleaf java.io.IOException: The filename, directory name or volume label syntax is incorrect

I'm building a web app on Spring MVC framework and using thymeleaf as my template engine.
I had a working app before adding a new REST controller. An IOException is now thrown
java.io.IOException: The filename, directory name or volume label syntax is incorrect

It's only happening when the browser attempts to fetch the css, js or any other static resources from my taoConnection-servlet.xml. The same occurs on both my jetty and tomcat7 deployments. After a couple of hours searching I can't find any similar problem.
edit: I'm making the call to the /account request mapping but it happens for all request mapping that access static resources. If I try to access the resources directly in the browser e.g. http://localhost:8080/css/bootstrap.min.css or http://localhost:8080/js/sb-admin-2.js the exception is thrown.
Alternatively if I try to access a fake resource e.g. http://localhost:8080/js/fake.js I still get a standard http 404 which is expected but the IOException is not thrown.

The error is letting you know that there is no open transaction when you are calling you DAO method and hitting the database. That means that the transaction management of the UserService is wrong.
I would try to change the transaction management of the UserService to create a transaction if there isn't already an existing:
#Service
#Transactional(propagation = **Propagation.REQUIRED**)
public class UserService {
If this works, the problem could be with the constructing of the spring xmls.

Exception : "No adapter for handler. Does your handler implement a supported interface like controller?"

I'm trying to validate a simple form in JSP with Spring and Hibernate using HibernateValidator. The JSP page Temp.jsp is as follows (the url pttern in web.xml is *.htm).
<%#page contentType="text/html" pageEncoding="UTF-8" %>
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%#taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<form:form method="post" action="Temp.htm" commandName="validationForm">
<!--validationForm is a model class-->
<table>
<tr>
<td>User Name:<font color="red"><form:errors path="userName" /></font></td>
</tr>
<tr>
<td><form:input path="userName" /></td>
</tr>
<tr>
<td>Age:<font color="red"><form:errors path="age" /></font></td>
</tr>
<tr>
<td><form:input path="age" /></td>
</tr>
<tr>
<td>Password:<font color="red"><form:errors path="password" /></font></td>
</tr>
<tr>
<td><form:password path="password" /></td>
</tr>
<tr>
<td><input type="submit" value="Submit" /></td>
</tr>
</table>
</form:form>
The class validationForm is as follows.
package validators;
import javax.validation.constraints.Max;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.NotEmpty;
import org.springframework.format.annotation.NumberFormat;
import org.springframework.format.annotation.NumberFormat.Style;
final public class ValidationForm
{
#NotEmpty
#Size(min = 1, max = 20)
private String userName;
#NotNull
#NumberFormat(style = Style.NUMBER)
#Min(1)
#Max(110)
private Integer age;
#NotEmpty(message = "Password must not be blank.")
#Size(min = 1, max = 10, message = "Password must between 1 to 10 Characters.")
private String password;
public void setUserName(String userName)
{
this.userName = userName;
}
public String getUserName()
{
return userName;
}
public void setAge(Integer age)
{
this.age = age;
}
public Integer getAge()
{
return age;
}
public void setPassword(String password)
{
this.password = password;
}
public String getPassword()
{
return password;
}
}
and the Controller class where the validation should be processed is as follows (I'm using SimpleFormController).
package controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import usebeans.TempService;
import validators.ValidationForm;
#SuppressWarnings("deprecation")
final public class Temp extends SimpleFormController
{
private TempService tempService=null;
public Temp()
{
//setCommandClass(Temp.class);
//setSuccessView("Temp");
//setFormView("Temp");
setCommandClass(ValidationForm.class); //Still not working.
setCommandName("validationForm");
}
public void setTempService(TempService tempService)
{
this.tempService = tempService;
}
#Override
protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception
{
ModelAndView mv=new ModelAndView();
ValidationForm validationForm=(ValidationForm) command;
tempService.add(validationForm);
return mv;
}
#Override
protected ModelAndView showForm(HttpServletRequest request, HttpServletResponse response, BindException errors) throws Exception
{
ModelAndView mv=new ModelAndView();
return mv;
}
}
In dispatcher-servlet, I have added the following.
<bean id="tempService" class="usebeans.TempServiceImpl" />
<bean name="/Temp.htm" class="controller.Temp" p:tempService-ref="tempService" p:formView="Temp" p:successView="Temp" />
Also tried adding the following bean still there is no luck.
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
Where the TempService interface is as follows.
package usebeans;
import validators.ValidationForm;
public interface TempService
{
public void add(ValidationForm validationForm);
}
and following is the TempServiceImpl class.
package usebeans;
import validators.ValidationForm;
final public class TempServiceImpl implements TempService
{
public void add(ValidationForm validationForm)
{
System.out.println("Message");
}
}
Although the class TempServiceImpl implements the TempService interface, I'm getting the following exception.

Edit :
Although I'm following what is explained here, the problem remains and I'm getting the same exception as mentioned above. What configuration settings am I missing here. It may be in the dispatcher-servlet.xml file. The entire dispatcher-servlet.xml file is as follows.

I don't have any precise idea about that exception being thrown. Can you figure it out why is that exception being thrown? What configuration settings or something else am I missing here?

I've fixed the issue, please find the new xml

Fix was related to <prop key="Temp.htm">tempController</prop>.
For the second error change the class Temp as below
package controller;

import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.validation.BindException;

public Temp() {
// setCommandClass(Temp.class);
// setSuccessView("Temp");
// setFormView("Temp");
setCommandClass(ValidationForm.class); // Still not working.
setCommandName("validationForm");
}
public void setTempService(TempService tempService) {
this.tempService = tempService;
}
#Override

model.put(getCommandName(), new ValidationForm());

}
