java - 如何使用 bean :profile 将 spring xml 从 3.0 转换为 3.1

Question

我在 3.0 中有一个像这样的 xml:

        <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="${jdbc.driverClassName}" />
            <property name="url" value="${jdbc.internal.url}" />
            <property name="username" value="${jdbc.internal.username}" />        
            <property name="password" value="${jdbc.internal.password}"/>
        </bean>

我想在使用 beans:profile 时将其转换为 3.1 但是，当我尝试将其更改为:

        <beans profile="dev">
          <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
              <property name="driverClassName" value="${jdbc.driverClassName}" />
              <property name="url" value="${jdbc.internal.url}" />
              <property name="username" value="${jdbc.internal.username}" />        
              <property name="password" value="${jdbc.internal.password}"/>
        </bean>
        </beans>

我收到如下错误:

Invalid content was found starting with element 'bean'. One of '{"http://www.springframework.org/schema/beans":beans}'

问题

我如何使用 beans:profile 以便仅当 Activity 配置文件为 dev 时才调用此特定 bean 定义

更新我的 bean 定义是:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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-3.1.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.1.xsd
       http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.1.xsd">

你必须把所有嵌套的<beans>配置文件末尾的声明。这就是 XML 模式的定义方式，您必须遵守这一点。

另见

• Spring Framework 3.1 M1 released :

  spring-beans-3.1.xsd has been updated to allow this nesting, but constrained to allow such elements only as the last ones in the file.
