mvc:resources Spring mapping not working

Question

I am trying to map any requests that come to /views/node_modules/* to /resources/angular_resources/* folder in my Spring project. How could I achieve this?

Currently I have applicationContext.xml file that looks the following way:

<context:component-scan
    base-package="fomoapp.domain, fomoapp.dao, fomoapp.service" />

<!-- Root Context: defines shared resources visible to all other web components -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:resources mapping="/views/node_modules/**" location="/resources/angular_resources/" />
<mvc:default-servlet-handler/>

Full web.xml:

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

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy
    </filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<servlet>
  <servlet-name>fomoapp</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/fomoapp-config.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>fomoapp</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.css</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/views/node_modules/</url-pattern>
</servlet-mapping>

I tried the solution here: Absolute path in <mvc:resources/> instead of path relative to mapping of spring servlet

But it does not work somehow.

If you would like to use tomcat and jsp. You can create a web MVC configurations and register handler to /static/** route

@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {
    private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
            "classpath:/META-INF/resources/", "classpath:/resources/",
            "classpath:/static/", "classpath:/public/" };
    /**
     *
     * @return
     */
    @Bean
    public ViewResolver internalResourceViewResolver() {
        InternalResourceViewResolver bean = new InternalResourceViewResolver();
        bean.setViewClass(JstlView.class);
        bean.setPrefix("/WEB-INF/views/");

        bean.setSuffix(".jsp");
        return bean;
    }
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations(CLASSPATH_RESOURCE_LOCATIONS);
    }
}

Static file can then be accessed from /static/{URL}. Note that in my case I used jasper, tomcat and jstl and static resources were placed under src/java/main/webapp

You can keep resources directory in Directory

• Eclipse: webapps

In JSP File

<link href="<c:url value="/resources/css/default.css"/>" rel="stylesheet" type="text/css"/>

Answer 3

Ultimately solved it. The following thread really helped me: Use of multiple "mvc:resources" tag in spring mvc.

So, I did the following:

1. Remove <mvc:default-servlet-handler/> from applicationContext.xml and add <mvc:annotation-driven /> at the bottom instead
2. Remove default servlet stuff from web.xml

After doing this I was able to add additional mappings to applicationContext.xml. Here it is:

<context:component-scan
    base-package="fomoapp.domain, fomoapp.dao, fomoapp.service" />

<!-- Root Context: defines shared resources visible to all other web components -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:resources mapping="/views/node_modules/@angular/**" location="/resources/angular_resources/@angular/" />
<mvc:resources mapping="/views/node_modules/rxjs/**" location="/resources/angular_resources/rxjs/" />

<mvc:annotation-driven />

You should map the static URLs to the Spring servlet, not the default servlet. So your code should be,

<servlet-mapping>
    <servlet-name>fomoapp</servlet-name>
    <url-pattern>*.css</url-pattern>
</servlet-mapping>
