springMVC 5.1.6 validation not working (BindingResult errors are 0 ?) - validation

Question

I am facing an issue with my "User" Object being Validated before being registered into a database
Used Technologies :
- Spring Web MVC with Hibernate Validator
- Spring Data (JDBC)
- Maven
Here is a snippet from my Controller Code :
#RequestMapping(method = RequestMethod.POST,params = "add")
public ModelAndView add(#Valid #ModelAttribute("user") User user, BindingResult result) throws Exception {
if (!result.hasErrors()) { // ERRORS NEVER HAPPEN ??
userDao3.insertUser(user);
}
return returnHome();
}
my User Validation is as follows :
#Size(min = 3, max = 20, message = "{required.name}")
String name;
#Min(value = 25, message = "{min.age}")
int age;
#Min(value = 2000, message = "{invalid.salary}")
float salary;
my jsp layout as follows :
<c:set var="contextPath" value="${pageContext.request.contextPath}"/>
<div class="container">
<form:form method="post" action="${contextPath}/?add" modelAttribute="user">
<div class="row">
<div class="col-15">
<tags:message code="field.username"/>
</div>
<div class="col-50">
<form:input cssClass="field" path="name"/>
</div>
<div class="col-25">
<form:errors path="name"/>
</div>
</div>
<div class="row">
<div class="col-15">
<tags:message code="field.age"/>
</div>
<div class="col-50">
<form:input cssClass="field" path="age"/>
</div>
<div class="col-25">
<form:errors path="age"/>
</div>
</div>
<div class="row">
<div class="col-15">
<tags:message code="field.salary"/>
</div>
<div class="col-50">
<form:input cssClass="field" path="salary"/>
</div>
<div class="col-25">
<form:errors path="salary"/>
</div>
</div>
<div class="row">
<input type="submit" value="Submit">
</div>
</form:form>
my Spring mvc Configuration xml file :
<mvc:annotation-driven/>
<bean name="homeController" class="Controllers.HomeController">
<property name="userDao2" ref="userDao2"/>
<property name="userDao3" ref="userDao3"/>
</bean>
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames">
<list>
<value>naming</value>
<value>ValidationMessages</value>
</list>
</property>
</bean>
and my pom's dependencies are :
