Spring MVC e Hibernate com multi DataSources

Preciso que o Spring MVC e Hibernate gerencie dois DataSources de bancos diferentes conforme o exemplo abaixo:

package br.com.centralizador.config;

import java.util.Properties;

import javax.persistence.EntityManagerFactory; import javax.sql.DataSource;

import org.springframework.context.annotation.Bean; import org.springframework.jdbc.datasource.DriverManagerDataSource; import org.springframework.orm.jpa.JpaTransactionManager; import org.springframework.orm.jpa.JpaVendorAdapter; import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean; import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter; import org.springframework.transaction.annotation.EnableTransactionManagement;

@EnableTransactionManagement public class ConfiguraJPA {

@Bean
public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean(DataSource dataSource, Properties properties) {
    LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
    JpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
    factoryBean.setJpaVendorAdapter(adapter);
    factoryBean.setDataSource(dataSource);
    factoryBean.setJpaProperties(properties);
    factoryBean.setPackagesToScan("br.com.centralizador.models");
    return factoryBean;
}

@Bean(name="dSourceMySql")
private DataSource dataSourceMySql() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
    dataSource.setUrl("jdbc:mysql://localhost:3306/centralizador?useTimezone=true&serverTimezone=UTC");
    dataSource.setUsername("user");
    dataSource.setPassword("xxxxxxxx");
    return dataSource;
}

@Bean(name="dSourceInformix")
private DataSource dataSourceInformix() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("com.informix.jdbc.IfxDriver");
    dataSource.setUrl("jdbc:informix-sqli://192.168.1.1:1526;InformixServer=call");
    dataSource.setUsername("user");
    dataSource.setPassword("xxxxxxx");
    return dataSource;
}

@Bean
public Properties propertiesMysql() {
    Properties properties = new Properties();
    properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
    properties.setProperty("hibernate.show_sql", "true");
    properties.setProperty("hibernate.hbm2ddl.auto", "update");
    return properties;
}

@Bean
public Properties propertiesInformix() {
    Properties properties = new Properties();
    properties.setProperty("hibernate.dialect", "org.hibernate.dialect.InformixDialect");
    properties.setProperty("hibernate.show_sql", "true");
    properties.setProperty("hibernate.hbm2ddl.auto", "validate");
    return properties;
}

@Bean
public JpaTransactionManager transactionManager(EntityManagerFactory emf) {
    return new JpaTransactionManager(emf);
}

}
