Cannot resolve class for Hibernate4

Question

I'm actually trying to import an external dao and an external persistence in a new Spring Boot application. I never do that before, and pursuant to another developper explanations, I've created:

ApplicationContext.xml :

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                           http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/context
                           http://www.springframework.org/schema/context/spring-context.xsd">

    <context:annotation-config />

    
    <import resource="classpath:/daos.xml" />
    <import resource="classpath:/spring-datasource-config.xml" />
    <import resource="classpath:/spring-hibernate-config.xml" />

    <bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer"/>
</beans>

then a Spring-hibernate-config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       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.xsd">

    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="mappingResources">
            <list>
                <value>mapping/JItem.xml</value>
             </list>
        </property>

        <property name="dataSource" ref="dataSource"/>

The problem is that it cannot find "org.springframework.orm.hibernate4.LocalSessionFactoryBean"

Did I forget something?

EDIT: I tried to force hibernate 4 in pom.xml (adding a property and declare the hibernate dependency at the end):

<?xml version="1.0" encoding="UTF-8"?>

            </plugin>
        </plugins>
    </build>

</project>

but it doesn't solve the problem and I still have the "cannot resolve class or package hibernate4" in the config xml....

I absolutely don't know how to solve this...
