Reading properties file in Spring mvc 4 issues - spring

Question

I am trying to read a property file in Spring mvc 4.1.6 version and I am having some issues.
Dispatcher-servlet.xml
<context:property-placeholder location="classpath:login.properties"/>
My class
#Component
public class UserCheck {
#Value("${server_ip}") String server_ip;
public String isUserPresent(String userName){
System.out.println("server_ip: " + server_ip);
return "";
}
}
I am getting the server_ip as null when I print the value. My login.properties is in src/main/resources folder.
I also tried #Value("${login.server_ip}"), but then I got a different error when deploying the application. I got
org.springframework.beans.factory.BeanCreationException: Error creating bean with name : Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field
Is there anything else that I need to do?
Thanks.
EDIT:
My properties file looks like below:
server_ip=192.168.1.1
My complete dispatcher servlet:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name = "prefix" value="/WEB-INF/jsp/" />
<property name = "suffix" value=".jsp" />
</bean>
<bean class="org.springframework.context.support.ResourceBundleMessageSource"
id="messageSource">
<property name="basename" value="messages" />
</bean>
This was added for testing**********************
<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
<property name="ignoreUnresolvablePlaceholders" value="true"/>
<property name="locations">
<list>
<value>classpath:application.properties</value>
</list>
</property>
</bean>
</beans>
EDIT 2:
My web.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>

</servlet>
<servlet-mapping>
<servlet-name>spring-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
EDIT 3: My controller class with the #PostConstruct method
#Controller
#SessionAttributes("userData")
public class UserController {
#Autowired
#Value("${server_ip}")
String server_ip;
#Value("${username}")
String username;
public #ResponseBody
#RequestMapping(value = "/validateuser")
String validateUser(#RequestParam("user") String user){
//UserCheck userCheck = new UserCheck();
//String test = userCheck.isUserPresent(user);
return "";
}//validateUser
#PostConstruct
public void init(){
System.out.println("server_ip in inti: " + server_ip);
System.out.println("username: " + username);
}
}

First of all, you would need the #Configuration annotation on the class. Not sure it would work with just #Component
Secondly, I don't know your project type and setup but if your .properties file ends up in WEB-INF/classes directory, then Spring should be able to pick it up.
EDIT:
You need to add this to your configuration file <context:annotation-config/>
