在类是字符串的地方创建Spring Bean？ [英] Create Spring Bean where class is a string?

问题描述

在Spring配置文件中是否可以使用某种bean工厂或静态类来创建Java类的实例并设置其属性？像这样：

Is there some kind of bean factory or static class that I can use within a Spring configuration file to create an instance of a Java class and set its properties? Something like this:

<bean id="myThingy" class="org.whatever.specialBeanMaker">
     <property class="${maven.filtered.property.value}" />
     <properties>
        <property name="a" value="...." />
        <property name="b" value="...." />
        <property name="c" value="...." />
     </properties>
</bean>

换句话说，我需要使用直到运行时才知道的类来制作bean（

In other words, I need to make a bean from a class I won't know until runtime (because of filtering, JNDI, propertyPlaceholderConfigurer, etc.

推荐答案

不需要任何特殊的东西，就像您期望的那样：

No need for anything special. Just do it like you'd expect:

<bean class="${whateverClass}"/>
