Step 1. Create resource directory
Step 2. Add tags in web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

<param-value>/WEB-INF/applicationContext.xml</param-value>

</listener>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.htm</url-pattern>
<url-pattern>*.css</url-pattern>
<url-pattern>*.js</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>
30
</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>redirect.jsp</welcome-file>
</welcome-file-list>
</web-app>
Step 3. Configure dispatcher-servlet.xml
<?xml version='1.0' encoding='UTF-8' ?>
<!-- was: <?xml version="1.0" encoding="UTF-8"?> -->

The problem is that your REGX pattern will only match the input “0-9”.
To meet your requirement (0-9999999), you should rewrite your regx pattern:
ng-pattern="/^[0-9]{1,7}$/"
HTML:
<div ng-app ng-controller="formCtrl">
<form name="myForm" ng-submit="onSubmit()">
<input type="number" ng-model="price" name="price_field" ng-pattern="/^[0-9]{1,7}$/" required>
<span ng-show="myForm.price_field.$error.pattern">Not a valid number!</span>
<span ng-show="myForm.price_field.$error.required">This field is required!</span>
<input type="submit" value="submit"/>
</form>
</div>
JS:
function formCtrl($scope){
$scope.onSubmit = function(){
alert("form submitted");
}
}
