Spring Data JPA + Hibernate +PostgreSQL

Question

i was following some tutorial to implement email verification ( http://www.baeldung.com/registration-verify-user-by-email ). for that, i need to make the spring data+hibernate working (never used both) i'm implementing that to the current proj where previously i implemented CRUD manipulation manually.

tried this proj as sample - http://devcrumb.com/hibernate/spring-data-jpa-hibernate-maven on sample everything works ok.

This is my current config:

Entity class:

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import java.util.List;    

@Entity
    public class User {

        public User() {
        }

        public User(String username, String password) {
            super();
            this.enabled=false;
        }

        @Id
        @GeneratedValue
        private Long id;

        @NotNull
        @Size(min=1, max=45)
        private String username;

        @NotNull
        @Size(min=1, max=60)
        private String password;

        @NotNull
        @Column(name = "enabled")
        private boolean enabled;

        @NotNull
        @Size(min=1, max=45)
        private String email;

        private Integer condo_id;

        @NotNull
        private List<String> roles;
    }

Hybernate config

<!--hibernate and some jpa config-->
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="packagesToScan" value="com.springapp.mvc" />
    <property name="dataSource" ref="dataSource" />
    <property name="persistenceUnitName" value="jpaData" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQL94Dialect</prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.format_sql">false</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
        </props>
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

    <persistence-unit name="jpaData" />

</persistence>

User repository

package com.springapp.mvc.dao.api.user;

import com.springapp.mvc.models.User;
import org.springframework.data.jpa.repository.JpaRepository;

public interface UserRepository extends JpaRepository<User, Long> {
    User findByEmail(String email);

    @Override
    void delete(User user);
}

also this in servlet config:

<context:component-scan base-package="com.springapp.mvc"/>
<jpa:repositories base-package="com.springapp.mvc" />

Constantly getting was different config errors. Current:

but the User.class described above loacated exactly there. com.springapp.mvc.models.User

Looking at the exception java.lang.NoClassDefFoundError: models/User It is trying to load User class from models package. But you have it in com.springapp.mvc.models package. Either make it load from this package where you have User class or move the User class under models package. — Madhusudana Reddy Sunnapu

But I think you said in your question User is in com.springapp.mvc.models.User i.e., it is not in models package. Isn't it? — Madhusudana Reddy Sunnapu

To be clear, models is not the same as com.springapp.mvc.models — Roman

Problem solved. before, i've done a rafactoring for this model. seems like some paths remained the same in IDE configs and that cause it. — user1935987

cleaning IDE config files and server files helped
