How can you set up Bean configurations using an XML file in Spring?

In Spring, bean configurations can be specified in an XML file using the <bean> tag. It indicates the class, properties, and dependencies.

Example of defining a bean with a property:

<bean id="myBean" class="com.example.MyClass">
    <property name="propertyName" value="propertyValue" />
</bean>

To set a dependency on another bean:

<bean id="dependentBean" class="com.example.DependentClass">
    <property name="myBean" ref="myBean" />
</bean>

Thus, the configuration described in XML is used by the Spring container to create and configure objects.
