We may get the above exception when working with Spring Boot with Config file (applicationConfig.xml) when you have injected a bean using property tag but the reference name is incorrect or the referenced bean does not exists.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean name="employee" class="org.code2care.demo.Employee">
        <property name="department" ref="dept"/>
    </bean>
    <bean name="department" class="org.code2care.demo.Department"/>
</beans>

As you can see in my case, the issue is that I have used the reference name as dept instead of department.
