Hibernate configuration using annotation in JAR module not working in Spring MVC EAR project

Question

I have created ear project with one web module and one EJB module.

I'm using web module for Spring MVC view and controller. Model, service and repository are maintained in ejb module. (tried in JAR module as well).

I'm getting exception like, [springframework.web.servlet.DispatcherServlet] (ServerService Thread Pool -- 168) Context initialization failed: java.lang.IllegalStateException: Cannot load configuration class: com.sakthi.core.config.HibernateConfiguration Exception.

Could anyone please help me?

My HibernateConfiguration class is,

package com.sakthi.core.config;
import java.util.Properties;

import javax.sql.DataSource;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
public class HibernateConfiguration {

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "com.sakthi.core.model" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
     }

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/test");
        dataSource.setUsername("root");
        dataSource.setPassword("root");
        return dataSource;
    }

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
        properties.put("hibernate.show_sql", "root");
        properties.put("hibernate.format_sql", "root");
        return properties;        
    }

    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory s) {
       HibernateTransactionManager txManager = new HibernateTransactionManager();
       txManager.setSessionFactory(s);
       return txManager;
    }

}

Answer 1

There's a mistake in your configuration above. Update this:

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
        properties.put("hibernate.show_sql", "root");
        properties.put("hibernate.format_sql", "root");
        return properties;        
    }

to the following:

    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
        properties.put("hibernate.show_sql", "true");
        properties.put("hibernate.format_sql", "true");
        return properties;        
    }

The IllegalStateException Exception may be caused by the fact that "root" is being passed to a boolean property. So it needs to be 'true' or 'false'.
