Question

我有两个Web应用程序（web-module1.war＆amp; web-module2.war），我想使用Web片段（web-core.jar）进行常见的servlet声明，如FacesServlet。

当我在web.xml中声明FacesServlet没问题时，但当我将此声明移动到web-fragment.xml时，我收到此错误：

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>

我对其他servlet /过滤器声明没有这个问题！

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

web-core.jar被声明为maven依赖项（我可以在WEB-INF / 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>

web-fragment.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>

    </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>

如果您正在使用Apache Myfaces JSF实现，那么这是一个已知的bug

所以你应该改变它（例如使用MOJARRA）

FacesServlet无法在Web片段中工作
