Adding js and css in Spring MVC

For adding js and css in Spring MVC app There are 2 ways.

First Way
we need to declare resources tag in dispatcher-servlet.xml (i.e spring bean configuration file).

Spring configuration file entry

<mvc:resources mapping="/resources/**" location="/resources/" />

Note:- Maintain the order
    <mvc:annotation-driven />
    <mvc:resources mapping="/resources/**" location="/resources/" />
    <context:component-scan base-package="com.pristine.controller" />

add in jsp

<script type="text/javascript"  

       src="${pageContext.request.contextPath}/resources/js/angular.min.js"></script>

 
Keep all js and css files in WebContent\resources folder

Second way
Declare in web.xml like below

<servlet-mapping>

       <servlet-name>default</servlet-name>

       <url-pattern>*.js</url-pattern>

</servlet-mapping>

<servlet-mapping>

    <servlet-name>default</servlet-name>

    <url-pattern>*.css</url-pattern>

</servlet-mapping>
