Difference in java ee between inject in a class and using jsp:useBean?

Question

Java

Hello everyone, can you tell me what is the difference in use? The result is still the same, only if you pass it from the servlet via session.setAttribute () or pass the class directly to jsp

@Inject
    @Default
    private Cities cities;// просто хранит массив

<c:forEach var="step" items="${sessionScope.cities}">
    <p>  ${step} </p>
</c:forEach>

<jsp:useBean id="cities" class="service.Cities">
    <c:forEach var="city" items="#{cities.cities}">
        ${city}
    </c:forEach>
</jsp:useBean>
