Serving static resources spring+jersey - java

I am trying to deploy my api + react frontend and managed to serve the built index.html but i am having trouble accessing the /static/** resources shown as so:
This is my webapp structure:
(ignore the index.html over the resources dir)
With my web.xml being:
<?xml version="1.0" encoding="UTF-8"?>

I tried adding a resource handler over my WebConfig as such but had no result:
#EnableAsync
#EnableTransactionManagement
#ComponentScan({"ar.edu.campus.webapp.controllers", "ar.edu.campus.services", "ar.edu.campus.persistence"})
#Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
...
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry
.addResourceHandler("/static/**")
.addResourceLocations("classpath:/spa-build/static");
registry
.addResourceHandler("/*.js")
.addResourceLocations("classpath:/spa-build/static/js");
registry
.addResourceHandler("/*.css")
.addResourceLocations("classpath:/spa-build/static/css");
registry
.addResourceHandler("/*.json")
.addResourceLocations("classpath:/spa-build");
registry
.addResourceHandler("/*.ico")
.addResourceLocations("classpath:/spa-build");
}
...
}
I can't really tell what's going wrong, tried multiple other things already but to no avail, i still get 404 over any resource i request.

Solved it by adding:
<webResources>
<resource>
<directory>../spa-client/build</directory>
</resource>
</webResources>
under the < configuration > tag for the maven-war-plugin

Spring 5 upgrade issue ResourceServlet

I'm moving from spring 4 to spring 5 (no spring boot yet) and after finally resolving dependency hell (at least I think so) I have problem with deploying app to tomcat with such stacktrace
Caused by: java.lang.ClassNotFoundException: org.springframework.web.servlet.ResourceServlet
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1305)
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1157)

I know that ResourceServlet is replaced with ResourceHttpRequestHandler but I cannot find place where I use in some way this ResourceServlet. Any idea how can I get rid of this is welcome.

correct way to provide Spring configuration files in web.xml

In my sample SPring project I'm using the following web.xml,
I think that it fails to properly use
root-context.xml
servlet-context.xml
security-context.xml
How should I change it in order to provide these three configuration files
correctly ?

Typical the filter-mapping is located after the servlet mapping (Adjusting web.xml listeners, filters and servlets)
One other thing looks strange: you wrote that you have a:
root-context.xml
servlet-context.xml
security-context.xml
Of course the name "root-context.xml" is not standardized, but I expect that his is the spring configuration file that contains the services, DAO, db connection but not the web-controller stuff. If it is so, then you should load your root-context.xml with the "inner-application context" created by ContextLoaderListener and configured by context-param contextConfigLocation. The security-context.xml MUST also been loaded by the ContextLoaderListener, so if there is no import for security-context.xml in root-context.xml then you must configure them both in contextConfigLocation
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/appServlet/root-context.xml,
/WEB-INF/spring/appServlet/app-security-context.xml
</param-value>
</context-param>
Maybe you should have a look at this question: ContextLoaderListener or not? - the question an the accepted answer explain a bit of how the two contexts work.

How to open popup in spring mvc application

I have following web application structure:
inside addTerminal.jsp I write following:
....
show map
...
function showMap(lat,lng) {
window.open('map.html?lat='+lat+'&lng='+lng, 'map', 'width=600,height=400');
}
....
But as client cannot access to WEB-INF folder I see 404 when click on href
Can you advice workaround how resolve my issue?
I think I can put map.html into webapp folder but I think exist another fix.

You simply need to create a controller that handles requests to map.html.
Something similar:
#RequestMapping("/map.html")
public String popup(#RequestParam("lat") String lat, #RequestParam("lng") String lng){
// your code here...
return "map";
}
You can use the mvc:resources tag to load items you consider resources.
<mvc:resources location="/web-inf/<path to html file>" mapping="<url context in a browser>" cache-period="86400"/>

Spring Security needs ContextLoaderListener but I'm using annotated configuration, what to do?

I was using annotated configuration for my Spring web app and then had to mix XML with it so that I could use Spring Security. I annotated one of my configuration classes with #ImportResource("security-config.xml") to load the security config. The configuration beans are being created just fine. My web.xml looks like so:

From what I understand the springSecurityFilterChain needs ContextLoaderListener. However, because of how my app is configured, if I add:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
to my web.xml my app doesn't initialize. Is there a way to manually create a ContextLoaderListener in my annotated configuration?
Just create a root application context by using the ContextLoaderListener.
<context-param>
<description>The Spring configuration files.</description>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/application.xml</param-value>
</context-param>
<listener>
<description>The Spring context listener.</description>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Inside the application.xml, you also can define the annotation based config. It will be inherited by the WebApplicationContext of your DispatcherServlet definition.
Then you import your security configuration inside the application.xml. So security will apply to all ApplicationContexts in your configuration.
I believe it works with the following additions under web-app
<context-param>
<param-name>contextClass</param-name>
<param-value>
org.springframework.config.java.context.JavaConfigWebApplicationContext
</param-value>
</context-param>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>com.website.config</param-value>
</context-param>
source : http://blog.springsource.com/2008/03/26/spring-java-configuration-whats-new-in-m3/
Do not forget to add "classpath:/" if your root.xml is somewhere different from the web.xml dir. Hope this will help someone in the future.
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/appcontext-root.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
