NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' is defined

Question

I have simple Spring 4 WebMVC app (Java-config), and I want to add JPA. But when I try to run app (as deloyed on Tomcat) I get: What can be a source of error?

Answer 1

in this question I posted a full example how to unit test a spring controller which needs an autowired JpaRepository.

Answer 2

You're missing completly DB configuration in your Config class.

Try this for example:

@Bean
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("org.hsqldb.jdbc.JDBCDriver");
    dataSource.setUrl("jdbc:hsqldb:mem:testdb");
    dataSource.setUsername("sa");
    dataSource.setPassword("");
    return dataSource;
}

@Bean
public EntityManager entityManager() {
    return entityManagerFactory().getObject().createEntityManager();
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    em.setPackagesToScan("package.where.your.entites.like.CustSys.are.stored");
    return em;
}
