Question

My question is simple. I am simply not able to load static resources in Spring Below are my configuration files.

I have put my js and css files in /webapp/resources/css and /webapp/resources/js.

I know this question has been addresses many times but I am simply not able to load static resources. I get 405 no method error on browser.

Tried every other solution on net. Kindly tell where am I going wrong. Really frustrated with these spring configuration files.

Answer 1

You are providing applicationContext*.xml whereas your name of context file is dispatcher-servlet.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:META-INF/spring/applicationContext*.xml</param-   value>
</context-param>

Moreover you have to read about usage of <mvc:default-servlet-handler/> and <mvc:resources> , from the documentation as both have a different way to serve static content, as follows:

With <mvc:default-servlet-handler/> spring dispatcher serve static resources under the web root (/webapp) using default servlet.

And with <mvc:resources> spring uses a convenient way to serve static resources from locations other than the web application root, including locations on the classpath.

Talking about your configuration, as you have do not have static resources under the web root, as you mentioned:

I have put my js and css files in /webapp/resources/css and /webapp/resources/js.

You have to edit the configuration to use either one of them to serve static files and have to access in a specific way, as follows:

Considering you are using convenient way to serve static file, as below:

<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources -->
<mvc:resources location="/resources/" mapping="/resources/**"/>

Then you have to access CSS and JS providing a path to a folder where /resources is the mapping attribute in mvc:resources tag:

<link href="<c:url value="/resources/css/my.css" />" rel="stylesheet">
<script src="<c:url value="/resources/js/my.js" />"></script>

Above snippet assume you have my.css and my.js in respective folder.
