How to set null value in Springs configuration file

[JavaBean]

This example shows the way to set the null value in the Spring configuration file.

<bean class="SampleBean">
<property name="name"><value></value></property>
</bean>

Results in the name property being set to "", equivalent to the java code: sampleBean.setName("").
The special <null> element may be used to indicate a null value, so that:

<bean class="ExampleBean">
<property name="email"><null/></property>
</bean>

The above configuration is equivalent to the java code:

exampleBean.setEmail(null).
