You need to configure CSRF protection in your view pages.

Spring 4 on wards, XML configuration is by default CSRF enabled. And JavaConfig is already CSRF enabled. So our UI pages should include 

<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>

Another approach to fix this error is disable CSRF protection.

In XML

<http>
<!-- ... -->
<csrf disabled="true"/>
</http>

In JavaConfig

@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable();
}
