java - 找不到任何 标签

Question

我想将 webflow 添加到 web。我在 pom.xml 中有 webflow 依赖项，我已经开始添加 beans，但似乎找不到任何标签，正如我在每个教程中看到的那样。我的所有 bean 都在 servlet-context.xml 中，就是这样:

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" 
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://www.springframework.org/schema/context 
                    http://www.springframework.org/schema/context/spring-context.xsd
                    http://www.springframework.org/schema/mvc
                    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
                     http://www.springframework.org/schema/webflow-config
    http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.3.xsd">


<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->

<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

    <beans:property name="driverClassName" value="com.mysql.jdbc.Driver"></beans:property>
    <beans:property name="url" value="jdbc:mysql://localhost:3306/myschema"></beans:property>
    <beans:property name="username" value="myusername"></beans:property>
    <beans:property name="password" value="mypassword"></beans:property>
</beans:bean>
<beans:bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <beans:property name="dataSource" ref="dataSource"></beans:property>
</beans:bean>

   <context:component-scan base-package="my.package" />

<beans:bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

    <beans:property name="mappings">
    <beans:value>inicio.do=flowController</beans:value>
    </beans:property>
    <beans:property name="alwaysUseFullPath" value="true"></beans:property>
</beans:bean>
<beans:bean id="flowcontroller" class="org.springframework.webflow.mvc.servlet.FlowController">
<beans:property name="flowExecutor" ref="flowExecutor"></beans:property>
</beans:bean>

当我尝试添加任何 webflow 标签时，例如:

<webflow:flow-executor id="flowExecutor" flow-registry="flowRegistry"/>

显示错误:

Multiple annotations found at this line:
- The prefix "webflow" for element "webflow:flow-executor" is not 
 bound.

似乎他找不到任何与 webflow 相关的标签，尽管我在 schemaLocation 中有它。

有什么帮助吗？谢谢。

编辑:我使用 Spring 3.1.1-RELEASE 版本，如 pom.xml 所示:

<org.springframework-version>3.1.1.RELEASE</org.springframework-version>

包含 webflow 命名空间，如下所示:

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