Kindly tell me, what should i do to stop getting this error
The main aim of adding this dependency is to protect my application with csrf filter

Answer 1

spring-security-bom has packaging defined as pom (<packaging>pom</packaging>)
Have a look at that tutorial
So in your case you have to define it like:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-bom</artifactId>
<version>5.0.6.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
After that you can define dependencies spring-security-* without using version.
Also have a look at the effective pom, which shows you what happens when you import another pom.
