I'm learning Spring Boot at the moment. I'm trying to insert some data in a mysql table using Spring Data Jpa. When I try to create my autowired repository interface I get this problem while running my application.
I got this error in the ReflectionUtils class:
Error creating bean with name 'frontcontroller': Unsatisfied dependency expressed through field 'databaseaction'
In my console i got this error:

Description:
Field databaseaction in com.example.demo3.controller.Frontcontroller required a bean named 'entityManagerFactory' that could not be found.
Action:
Consider defining a bean named 'entityManagerFactory' in your configuration.
How do I rectify this problem. I'm using IDE STS-4
Source code:
Controller class:
package com.example.demo3.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.example.demo3.model.usermodel;
import com.example.demo3.repository.Databaseaction;
@Controller
public class Frontcontroller {
@Autowired
Databaseaction databaseaction;
@RequestMapping("/")
public String getreq() {
System.out.println("method called");
return "index";
}
@RequestMapping(value = "save", method = RequestMethod.POST)
public ModelAndView save(usermodel user) {
ModelAndView mv = new ModelAndView();
try {
databaseaction.save(user);
System.out.println(user);
System.out.println(user.getFname());
System.out.println(user.getLname());
System.out.println(user.getEmail());
System.out.println(user.getMobNo());
System.out.println(user.getAddress());
} catch (Exception e) {
System.out.println("");
}
return mv;
}
}
Model class :
package com.example.demo3.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class usermodel {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int ID;
private String Fname;
private String Lname;
private String Email;
private String MobNo;
private String Address;
public int getID() {
return ID;
}
public void setID(int iD) {
ID = iD;
}
public String getFname() {
return Fname;
}
public void setFname(String fname) {
Fname = fname;
}
public String getLname() {
return Lname;
}
public void setLname(String lname) {
Lname = lname;
}
public String getEmail() {
return Email;
}
public void setEmail(String email) {
Email = email;
}
public String getMobNo() {
return MobNo;
}
public void setMobNo(String mobNo) {
MobNo = mobNo;
}
public String getAddress() {
return Address;
}
public void setAddress(String address) {
Address = address;
}
}
Repository interface : (here i've tried @Repository,@Service,@Component everything)
package com.example.demo3.repository;
import org.springframework.data.repository.CrudRepository;
import com.example.demo3.model.usermodel;
public interface Databaseaction extends CrudRepository<usermodel, Integer> {
}
application.properties :
spring.mvc.view.prefix=/pages/
spring.mvc.view.suffix=.jsp
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/learningspring
spring.datasource.username=root
spring.datasource.password=""
