element 'beans'.

I was tried delete "7 line" but then I had exception about "6 line" =D please help me to understand what is wrong

Answer 1

You may need to add the spring-beans dependency to your maven.

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>4.1.8.RELEASE</version>
</dependency>

Answer 2

You need to specify the version of Spring you are using in your servlet config - in your case spring-beans-4.1.xsd :

xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
...

Answer 3

Can you please try with the below servlet xml? In this I removed the closing tags, instead used them as <context:annotation-config /> and <context:component-scan /> . Also please provide your full package name in component-scan

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

    xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">
    <context:annotation-config />
    <context:component-scan base-package="controllers" />
</beans>
