Spring: How to inject a property value into the bean via XML?

问题

I have a bean with injected field value. It works just fine. I use annotation to ask Spring to inject value from properties into the bean.

public class MyBean {
    @Value("${app.settings.value}")
    private String value;
}

How can I do the same via XML? I've tried to inject using value="#{}".

<bean id="myBean" class="com.test.MyBean">
    <property name="value" value="{app.settings.value}"/>
</bean>

But my approach does not work.

回答1:

Try this:

<bean id="myBean" class="com.test.MyBean">
    <property name="value" value="${app.settings.value}"/>
</bean>

The syntax is the same as for java config - prefixed with the $ sign.
