java.lang.IllegalArgumentException：无效 [过滤器映射中的[Faces Servlet]

Question

我在我的应用中为我的entityManager构建控件过滤器，但出现此错误：

当我在类JPAFilter中定义@WebFilter("Faces Servlet")时。我更改为@WebFilter(".xhtml")，但是entityManager在数据库中创建了很多连接。

我的JPAFilter类：

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

    private EntityManagerFactory entityManagerFactory;
    private String persistence_unit_name = "comex-pu";

    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 {
            entityManager.close();
        }
    }

    public void init(FilterConfig fConfig) throws ServletException {
        this.entityManagerFactory = Persistence.createEntityManagerFactory(this.persistence_unit_name);
    }
}

[我的Faces Servlet中的web.xml：

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

错误说：非法。因此，不允许使用带空格的名称。从以下位置更改过滤器中的映射和符号：
