How to install the Springframework CrudRepository?

Question

I'm following this tutorial to create a CRUD application with Spring. I want to create a repository and I want it to extend the Spring CrudRepository:

package com.movieseat.repositories;

import java.io.Serializable;

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;


import com.movieseat.models.Movie;

public interface MovieRepository extends CrudRepository<Movie, Serializable> {}

Visual Studio Code is saying:

The import org.springframework.data cannot be resolved

I've removed the repository folder in the .m2 folder and do a reinstall but still no success.

I think I'm missing a dependency in my pom.xml file but I can't found it which one.

//edit. Sharing the pom.xml that's in the back-end folder:

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Answer 1

The gradle file in your tutorial imports the following Spring data JPA dependency

dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    ...
}

It's maven equivalent is :

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.11.7.RELEASE</version>
</dependency>

So, you must add the above dependeny in your pom file.

Answer 2

Use following Maven Dependency

<!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-commons-core -->
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-commons-core</artifactId>
    <version>1.0.0.RELEASE</version>
</dependency>

You can change verison of it depending upon Spring version you are using. User following link. https://mvnrepository.com/artifact/org.springframework.data/spring-data-commons-core
