FacesServlet不在web片段中工作

Question

我有两个web应用程序(web-module1.war和web-module2.war)，我想使用一个web片段(web-core.jar)来实现像FacesServlet这样的常见servlet声明。

当我在FacesServlet中声明web.xml没有问题时，但是当我将这个声明移到web片段中时，我会得到以下错误：

java.lang.IllegalStateException: No Factories configured for this Application. 
This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

我在其他servlet/过滤器声明中没有这个问题！

web-Frament.xml位于web-core.jar的META文件夹以及faces-config.xml中。

can被声明为maven依赖项(我可以在WEB/lib中找到它)。

这是web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" metadata-complete="false"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

    <absolute-ordering>
        <name>core_web_fragment</name>
    </absolute-ordering>

</web-app>

和web-Frament.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-fragment metadata-complete="true" version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-fragment_3_0.xsd">

    <name>core_web_fragment</name>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-*.xml</param-value>
    </context-param>
    <!-- /Spring Config -->
    <context-param>
        <param-name>javax.faces.PROJECT_STAGE</param-name>
        <param-value>Development</param-value>
    </context-param>
    <context-param>
        <param-name>javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL</param-name>
        <param-value>true</param-value>
    </context-param>
    <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>

    <welcome-file-list>
        <welcome-file>inscription.xhtml</welcome-file>
    </welcome-file-list>
</web-fragment>

我用的是Tomcat7

如果您正在使用Apache实现，这是一个已知的bug

所以你应该改变它(例如，使用MOJARRA )
