quando defino @WebFilter("Faces Servlet")类JPAFilter.Troquei por @WebFilter（“。xhtml”），massityentityManager可以转换为banco。Minha类JPAFilter：

`package br.faraway.nicholas.filters;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;

/**

@WebFilter("Faces Servlet")
public class JPAFilter implements Filter {

    private EntityManagerFactory entityManagerFactory;

    private String persistence_unit_name = "comex-pu";

    public JPAFilter() {

    }

    public void destroy() {

        this.entityManagerFactory.close();
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

        EntityManager entityManager = this.entityManagerFactory.createEntityManager();


        request.setAttribute("entityManager", entityManager);


        entityManager.getTransaction().begin();


        chain.doFilter(request, response);

        try {


            entityManager.getTransaction().commit();

        } catch (Exception e) {


            entityManager.getTransaction().rollback();
        } finally {
            System.out.println("Finalyu");

            entityManager.close();
        }
    }

    public void init(FilterConfig fConfig) throws ServletException {

        this.entityManagerFactory = Persistence.createEntityManagerFactory(this.persistence_unit_name);
    }
