Spring MVC and Spring Data Repository doesnt work

I am trying to make a simple Spring MVC application using Spring Data, hibernate and H2 database. But spring cannot find the repository as a bean.
The error when application start:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'taskService': Unsatisfied dependency expressed through method 'setTaskRepository' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.spring.intership.repositories.TaskRepository' available: expected at least 1 bean which qualifies as autowire candidate.

I have very little experience in MVC spring (a little more in boot) so please consider the most obvious mistakes too;
P.S. My Task.java

private String description;
private Date date;
#Id
#Column(name = "ID")
public long getNumber()
{
return number;
}
#Basic
#Column(name = "DESCRIPTION")
public String getDescription()
{
return description;
}
#Basic
#Column(name = "DATE")
public Date getDate()
{
return date;
}
public void setNumber(long number)
{
this.number = number;
}
public void setDate(Date date) {
this.date = date;
}
public void setDescription(String description) {
this.description = description;
}
}

try this tips:
Use "#ComponentScan" annotation in "BeanConfiguration" class. Note that you can use "#ComponentScan(basePackages = "com.example.package")" to force scan of the package when your repositories are.
You can use "#EnableJpaRepository(basePackages = "package.of.repositories")" to scan specific package to find ONLY repositories.
Let's check if "Task" class is annoted with "#Entity"
Consider to convert you context to class and try to use annotation instead of xml bean definition.
If you choose to use #ComponentScan annotation consider to scan all packages' tree. If your packages are "com.example.repository", "com.example.controller", "com.example.service" let's scan "com.example" in order to scan also future packages' you will add

I agree with #Luke.
Also you should autowire TaskRepository in TaskService.
public class TaskServiceImpl implements TaskService {
#Autowired
private TaskRepository taskRepository;
....

Hibernate Bean Creating Exception

I am using Spring-ORM to add a Employee* object in Table called emp using HibernateTemplate.
But when I'm trying to execute the program I'm getting this error:
Error creating bean with name 'testBean': Unsatisfied dependency expressed through field 'dao'; nested exception is
org.springframework.beans.factory.UnsatisfiedDependencyException:E rror creating bean with name 'empDaoImpl': Unsatisfied dependency expressed through field 'ht'; nested exception is

This is My java bean
#Service

#Autowired
private EmpDao dao;
public void persistEmp(int empid,String empName,int sal,int deptno)
{
Employee e=new Employee();

*This is my Entity class

#Column(name="deptno")
private int deptNum;
//Setters and Getters
public String toString()
{
return "Employee["+empid+" "+empName+" "+empSalary+" "+deptNum+"]";
}
}
This is my EmpDaoImpl class
#Repository

public class EmpDaoImpl implements EmpDao

private HibernateTemplate ht;

{
Employee e=(Employee)ht.get(Employee.class, empid);

When hibernate.hbm2ddl.auto is set to update Hibernate won't modify existing table column definitions. So, you can manually alter the column definition or drop the table/column and run your code. In the latter case, hibernate will create the column if it is not present.
Please refer here, here and here for more info on hibernate.hbm2ddl.auto options and how they work.

can anyone help me to getting out from this errors/exceptions.
Thanks in advance.

I am not exactly sure whether this solution will work just a small hunch.
Replace :
Resource r = new ClassPathResource("applicationContext.xml");
BeanFactory factory = new XmlBeanFactory(r);
EmployeeDao dao = (EmployeeDao)factory.getBean("d");
with :
ApplicationContext r = new ClassPathXMLContext("applicationContext.xml);
Employee dao = r.getBean("d");

Spring + Hibernate, can not read xml error

I am a newbie in Spring + Hibernate, but I have worked on this problem for last one day. I still can not figure out what is the root cause, and what should I do. So, thank you in advance if any one can give me some advice.
Here is a problem, I just write a simple test class, but when I ran, there is an exception:

And here is the smiple test class source code:
/**

package com.xw.test;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.domain.Employee;
/**
* #author Administrator

*/
public class Test {
/**
* #param args
*/
public static void main(String[] args) {
ApplicationContext ac = new ClassPathXmlApplicationContext("ApplicationContext.xml");
SessionFactory sf = (SessionFactory) ac.getBean("sessionFactory");
Session s = sf.openSession();
Employee employee = new Employee( "aa", "aa.sohu#com", new java.util.Date(),
(float) 234.56) ;
Transaction tx = s.beginTransaction();
s.save(employee);
tx.commit();
}
}
Thank you so much for any advice!

The properties should be declared like below inside your sessionFactory Bean.
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
</props>
so your sessionFactory bean would be like below.
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>com/domain/Employee.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
</props>
</property>

sometimes there is a chance of cant pick ur config files because of compiler dont konw which file shoul it take for configuration.so for this reason u should explicitly import those config file via 2 methods as i know
1)by using class
#Configuration
#ImportResource(value = {"classpath:{filename-within-resource}/Employee.hbm.xml"},"classpath:{filename-within-resource}/ApplicationContext.cfg.xml")
public class CommonSolutionConfig {
}
2)by using xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
<import resource="classpath:{filename-within-resource}/Employee.hbm.xml"/>
<import resource="classpath:{filename-within-resource}/ApplicationContext.cfg.xml"/>
</beans>
hopefully it will solve ur problem

I have tried to link through JDBC and it's working fine.

salary field has int type, but there is double in the hibernate mapping

This might be caused because the hibernate trying retrieving the dtd file. so, the workaround could be :
change the value of the dtd from that to "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"
Create your own function to parse the configuration then passed to the hibernate like this
public static Document parseConfiguration(String resourcePath) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false); <-- the magic is here
DocumentBuilder builder = factory.newDocumentBuilder();
return builder.parse(builder.getClass().getResourceAsStream(resourcePath));
}

I am not getting the error you are getting, though I fixed lot of errors in your entity (properties defined in the mapping file not present in the entity). I have reached the step where it is trying to insert the record, so I am well past the stage where you are getting the error.
By looking into the hibernate source file (org.hibernate.cfg.Configuration.addInputStream(Configuration.java:499)) which is throwing error, hibernate is not able to reach your mapping xml file.
Please double check if the mapping file is at proper location and also readable.
Also make sure you have correct version of hibernate jar in the classpath.
