Spring Security - Unable to locate Spring NamespaceHandler — security

Question

I have exception: org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/security] Offending resource: ServletContext resource [/WEB-INF/spring/security.xml]

Few minutes in google, say me, I need to add dependence -- spring-security-config. I have this, the latest version 4.2.1, but exception there is.

security.xml

maven

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>4.2.1.RELEASE</version>
</dependency>

This is likely an unresolved dependency. Without seeing your Maven pom or project configuration, the bare minimum for Spring Security is:

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>4.2.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>4.2.1.RELEASE</version>
</dependency>

If you are using Spring Tool Suite or Eclipse, be sure to right click your project, then select Maven -> Update Project and do a full clean install
