Question

我正在用Java 8编写Web应用程序。我使用Maven并在项目中包含了有关Spring Webflow的依赖项：

    <dependency>
        <groupId>org.springframework.webflow</groupId>
        <artifactId>spring-webflow</artifactId>
        <version>2.4.5.RELEASE</version>
    </dependency>

我使用基于表单的身份验证，我的web.xml如下所示：

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app id="PROJECT" 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-app_3_0.xsd"
        xmlns:h="http://java.sun.com/jsf/html" xmlns:p="http://primefaces.org/ui"
        xmlns:pt="http://xmlns.jcp.org/jsf/passthrough" xmlns:o="http://omnifaces.org/ui"
        xmlns:of="http://omnifaces.org/functions">

        <display-name>PROJECT</display-name>

    /* 
    *   Somewhere here should I insert something in order to have
    *   my web application informed, that there is a spring-webflow-config.xml
    *   configuration file. How do I do this?
    */

        <welcome-file-list>
            <welcome-file>WEB-INF/firstPage.xhtml</welcome-file>
        </welcome-file-list>

        <security-constraint>
            <display-name>Constraint</display-name>
            <web-resource-collection>
                <web-resource-name></web-resource-name>
                <description />
                <url-pattern>/flows/*</url-pattern>
            </web-resource-collection>

            <auth-constraint>
                <description />
                <role-name>ADMIN</role-name>
                <role-name>USER</role-name>
            </auth-constraint>

        </security-constraint>

        <login-config>
            <auth-method>FORM</auth-method>
            <realm-name>file</realm-name>
            <form-login-config>
                <form-login-page>WEB-INF/login.xhtml</form-login-page>
                <form-error-page>WEB-INF/error.xhtml</form-error-page>
            </form-login-config>
        </login-config>

        <security-role>
            <description>Administration</description>
            <role-name>ADMIN</role-name>
        </security-role>
        <security-role>
            <description>User</description>
            <role-name>USER</role-name>
        </security-role>

    </web-app>

我还创建了spring webflows的配置，我把它命名为“WEB-INF \ config \ spring-webflow-config.xml”，它看起来像这样：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:webflow="http://www.springframework.org/schema/webflow-config"

xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
    http://www.springframework.org/schema/webflow-config
    http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.0.xsd">


<mvc:annotation-driven />

<!-- Webflow Configuration -->
<webflow:flow-executor id="flowExecutor" />

<webflow:flow-registry id="flowRegistry">
    <webflow:flow-location-pattern value="/WEB-INF/flows/*-flow/*-flow.xml" />
</webflow:flow-registry>

<bean id="flowMappings"
    class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
    <property name="order" value="0" />
    <property name="flowRegistry" ref="flowRegistry" />
</bean>

<bean class="org.springframework.webflow.mvc.servlet.FlowHandlerAdapter">
    <property name="flowExecutor" ref="flowExecutor" />
</bean>

在上面的代码中，我声明了我想要为我的webflows关注的文件夹/ url-pattern

/WEB-INF/flows/*-flow/*-flow.xml

问题是，如何通知我的网络应用程序有spring webflow的配置？

我查了很多例子和教程，但由于一些有趣的原因，没有人解释

a）每个配置文件应放在哪个文件夹中，

b）配置文件应具有的名称，以便从Spring Webflow框架中识别。

如果您知道如何“通知”我的网络应用程序Spring Webflow，请告知我们。

提前谢谢。

放置Webflow配置文件的位置并不特别重要，您只需告诉Spring DispatcherServlet：

<servlet>
    <servlet-name>Spring MVC Dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            /WEB-INF/config/spring-webflow-config.xml
        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>Spring MVC Dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

它可能并不明显，但它是Spring MVC设置，由WebFlow官方文档的这一部分描述：http://docs.spring.io/spring-webflow/docs/current/reference/html/spring-mvc.html#spring-mvc-config-web.xml

如何通过web.xml“通知”我的Web应用程序，我有一个关于Spring Webflow的配置文件？
