Spring with JPA not persisting objects

Question

I have read many tutorials to config spring with JPA. I am using a local MySQL database and i have this context:

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!-- DataSource Setup -->
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/test" />
        <property name="username" value="vitornobrega" />
        <property name="password" value="" />
    </bean>

    <!-- Entity Manager Factory -->
    <bean id="entityManagerFactory"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="packagesToScan" value="com.vitornobrega.myapp.entities" />
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="showSql" value="true" />
                <property name="generateDdl" value="true" />
                <property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect" />
            </bean>
        </property>
    </bean>

    <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>
    <tx:annotation-driven transaction-manager="txManager" />
</beans>

I have a test on JUnit to test my DAO and works nice but when i try to persist an entity with this config, i never the in hibernate log the insert command but in test case i see it. If i try to make a entitymanager.flush i get an exception because any transaction is running.

What i should change to can make persist on my local database with this entities? thanks

could you share please your stacktrace to see what the error is? So we can analyze it better and help you. — Marcelo Tataje

If i try to make a entitymanager.flush i get an exception because any transaction is running.

If I'm reading that right, the problem is you're trying to save something without starting a transaction. Transactions are required when changing persistent state.

In order to be able to persist in database it is mandatory to be within a transaction. So the better you can solve it is to annotate @Transactional ... e.g. on the method

This also make me crazy for couple of hours some time ago.

are you using annotations in your classes? if so please make sure you <context:component-scan base-package="com.vitornobrega.myapp"> because arpart from the jpa configurations i can see where you are injecting your dependencies.
