Question

Answer 1

As an additional way to @jisun's reply.I did it by annotation configuration and removed more properties such as username,password,driver etc.Because all of these parameters can be define in persistence.xml:

package com.company.config;

import javax.annotation.Resource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.core.env.Environment;
import org.springframework.instrument.classloading.ReflectiveLoadTimeWeaver;
import org.springframework.orm.jpa.JpaTransactionManager;

@Configuration
@ComponentScan(basePackages = "com.company")
@EnableTransactionManagement
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter {


    @Resource
    private Environment env;

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
        emf.setPersistenceXmlLocation("classpath:persistence.xml");
        emf.setLoadTimeWeaver(new ReflectiveLoadTimeWeaver());
        return emf;
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        return new JpaTransactionManager(entityManagerFactory().getObject());
    }

}
