Intellij Idea - Could not autowire. No beans of 'ApplicationRepository' type found. less... (Ctrl+F1) Checks autowiring problems in a bean class

I am Java newbie.

I am making this tutorial (Spring MVC + Hibernate + Tomcat)

Everything goes fine till now. When I tried to make a ApplicationController I could not autowire ApplicationRepository.

I get this error message and 404 error code when I deploy application:

Could not autowire. No beans of 'ApplicationRepository' type found. less...     
(Ctrl+F1) 
Checks autowiring problems in a bean class.

Ok talk is cheap.

Here goes the repo (github!): https://github.com/maciejkowalski/sample-spring-app

Tomcat stacktrace: https://gist.github.com/maciejkowalski/c7512d82feb75fcebd5f

Here is the code:

root/src/main/java/wzpweb/

package wzpweb;

import javax.persistence.*;

@Entity(name = "applications")
public class Application {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Basic
    private String name;

    @Basic
    private String ip;

    @Basic
    private Boolean alive;

    @Basic
    private Integer port;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public Boolean getAlive() {
        return alive;
    }

    public void setAlive(Boolean alive) {
        this.alive = alive;
    }

    public Integer getPort() {
        return port;
    }

    public void setPort(Integer port) {
        this.port = port;
    }

EDIT #1

I have edited web.xml and added code:

<web-app version="2.4"
    xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

    <display-name>Spring MVC Application</display-name>

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

But now I get Element listener-class is not allowed her from Intellij IDEA.

And my app even doesnt deploy.

EDIT #2

Well problem still occurs.

I renamed persistance.xml to persistence.xml.

Restarted Intellij idea and still getting this error.

Maybe this is a bug?

I will probably surrender with this Spring stuff, it's beyond me...

Similar issue come when you have created ObjectService and instantiated the same in the RestController and you havent annotated the ObjectServiceImpl with @Service.

removing the Spring facet (File->Project Structure) Kill the project configuration in the facet of the relevant module configuration content, the IDEA is automatically identified. After the removal, the relevant error disappears. Does not affect compilation.

I followed the same tutorial and ran into the same code inspection warning (even if the application was working fine, the IDE was complaining). To make fix it, I added @Repository to my JpaRepository:

For your example:

package wzpweb;

import org.springframework.data.jpa.repository.JpaRepository;

@Repository
public interface ApplicationRepository extends JpaRepository<Application, Long> {
}

Rename your file persistance.xml to persistence.xml. The persistence.xml is, by default, the name of the file needed in the META-INF/ directory to define a persistence unit needed by your entityManagerFactory.

Here's a blog post explaining how Spring uses your custom interface implementing JpaRepository to generate an implementation class. I originally thought that you needed an implementation class for it, but that is not the case.

Small bug in the naming is your problem, given away by your first exception in the stack trace.

javax.persistence.PersistenceException: No Persistence provider for EntityManager named defaultPersistenceUnit

Add a context loader listener to your web.xml to read the Spring app context XML on startup.

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/context/applicationContext.xml,/WEB-INF/context/applicationContext-*.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
