Hibernate Template throwing error while Autowirring

Currently I'm facing an issue in Autowire configuration between controller and the HibernateTemplate.
I'm unable to trace my mistakes.
I Want to do Autowired Hibernate Template But It gives this error can
implementation of hibernate template is required to provide manually
bellow i given my dispatcher servlet, java controller and error
this one is my dispatcher servlet code

To enable #Autowired, you have to register ‘AutowiredAnnotationBeanPostProcessor‘, and you can do it in two ways :
Include <context:annotation-config />
Add Spring context and in bean configuration file.
<beans
//...
xmlns:context="http://www.springframework.org/schema/context"
">
//...
<context:annotation-config />
//...
</beans>
Include AutowiredAnnotationBeanPostProcessor
Include ‘AutowiredAnnotationBeanPostProcessor’ directly in bean configuration file
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
..>
<bean
class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
...
</beans>

there is no bean of type HibernateTempate in your application context.
add these lines
<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory"><ref bean="sessionFactory"/></property>
</bean>
see this answer before you user hibernate template.

You need to enable annotation in your spring configuration, try adding below in your spring configuration:
<context:annotation-config />
<bean
class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />

can someone help me. i already search for similar problem, but still not get what the error.

You should add annotation #Inject or #Autowired for your RegisterController::userDAO field, then it will be properly initialized.

You have defined
private UserDAO userDAO;
And then you call
userDAO.create(whatever);
at this point in time, no value has been assigned to userDAO, hence, null. You need to instantiate the object.

org.springframework.beans.factory.BeanCreationException with Transaction Manager

I've been studying Spring MVC on a Restful application, but I'm struggling to get it working.
My application have the following structure:
#Entity Classes
#Repository Classes (which use #Transactional for queries)
#RestfulController Classes (for simplification, I didn't implemented the service layer)
I want to use #Transactional for queries, but I'm getting the error message on server start when I configure it on spring xml file.

This error only happens if I add the following config in my spring config file:
<tx:annotation-driven transaction-manager="transactionManager"/>
If I remove this line, the problem disappears, the Restful requests works fine, but, the Repository methods doesn't save the data. In this case, the message below is shown (this error ocurred on another Controller, as Callendar functionality isn't finished. Although, the exception is related, as it verses about Transaction):

Thanks in advance for looking to my question!

Your repository field in the CalendarController should be defined by the interface, not with the class. Spring creates a Proxy around your CalendarRepository which implements the same interfaces, but is not a subclass of CalendarRepository.
This question was about exactly the same problem: #Autowired return exception on UserDetails in Spring-security
You are trying to autowire your user details service by class, but that can't work, because the spring bean is actually a proxy created around that class (and not an instance of the class). The proxy will however implement all interfaces of the original bean, so injecting by interface is safe.
Exchange this line:
#Autowired
private MyCustomUserDetailsService myCustomUserDetailsService;
for this one:
#Autowired
private UserDetailsService myCustomUserDetailsService;
Read the section on Proxying Mechanisms in the Spring AOP to understand the details.
So in your case, you could create a new interface CalendarRepository with the methods you need, and then implement then in class CalendarRepositoryImpl implements CalendarRepository:
interface CalendarRepository extends br.com.milo.repository.Repository<Calendar, Owner>{
void save(Calendar calendar);
void update(Calendar calendar);
void delete(Integer id);
... (and all other methods you need)
}
#Repository
class CalendarRepositoryImpl implements CalendarRepository {
... (what you currently have in CalendarRepository)
}
class CalendarController {
#Autowired
CalendarRepository repository; // NOT CalendarRepositoryImpl
}

The main problem here could be the duplicate mvc:annotation-driven declaration.
But anyway, Spring 4.1 introduced Gson support so that makes it way easier for you to achieve this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="cz.ario.socialgraphui.controller" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<mvc:annotation-driven>
<mvc:message-converters>
<bean class="org.springframework.http.converter.json.GsonHttpMessageConverter" />
<!-- other HttpMessageConverters you need here -->
<!-- Also: why adding Jackson's MessageConverter? Gson should pick JSON serialization in this case -->
</mvc:message-converters>
</mvc:annotation-driven>
<mvc:resources mapping="/scripts/**" location="/scripts/" />
<mvc:resources mapping="/styles/**" location="/styles/" />
</beans>
Same thing with a JavaConfig example:
#Configuration
#EnableWebMvc
#ComponentScan("cz.ario.socialgraphui.controller")
public class WebConfig extends WebMvcConfigurerAdapter {
#Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
converters.add(new GsonHttpMessageConverter());
// ...
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/scripts/**").addResourceLocations("/scripts/");
registry.addResourceHandler("/styles/**").addResourceLocations("/styles/");
}
}
Note: you should (almost) never use versioned XSDs in your XML configuration files - see this SO question for more details.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'signupController' defined in file

Im previously wrote the code which save data from form in spring and it worked fine.
Now i have tried to wrote the code which get data from android client and save it in mysql database. but in result i have a problem
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'signupController' defined in file
Also i dont understand why i have such problem if i have in dispatcher-servet
<context:component-scan base-package="com.dubovskiyM.mvc"/>
<context:annotation-config/>
Or can this problem cause because controller and repository situated in differends folders. but in one package com.dubovskiyM.mvc?
My files

"Only one annotated constructor per-class can be marked as required, but multiple non-required constructors can be annotated. In that case, each is considered among the candidates and Spring uses the greediest constructor whose dependencies can be satisfied, that is the constructor that has the largest number of arguments." per Spring doc
So remove the default constructor and try.
