将bean配置为'；可选'；在spring applicationcontext.xml中

我在spring

appingcontext.xml中定义了以下bean

<bean id ="seleniumDriver" class="org.openqa.selenium.firefox.FirefoxDriver">
    <constructor-arg><ref bean="capabilities"/></constructor-arg>
</bean>

我有一个不想加载那个bean的需求，所以我运行我的项目时匹配webdriver参数，即“mvn clean test”，但是我得到了下面的异常

原因：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'seleniumDriver' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.openqa.selenium.firefox.FirefoxDriver]: Constructor threw exception; nested exception is org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed.`

我在这里读了一些帖子，了解到我们可以在java类中使用
@Autowired（required=false）
或重写
applicationcontext
，但我不想接触java代码，而是想通过XML配置来实现，有什么办法吗？
使用bean配置文件，并在需要时激活该配置文件中的bean。
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'seleniumDriver' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.openqa.selenium.firefox.FirefoxDriver]: Constructor threw exception; nested exception is org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed.`
