Spring boot taglibs

I added following dependency:

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
</dependency>

Now it works.

Add the following dependency

For : <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%> :  

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>


For : <%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags"%> :

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
</dependency>
