Question

Tengo el proyecto web Eclipse Maven donde uso Spring mvc y Spring security . Cuando me limito a lanzarlo, no se logra inicializar el contexto:

Could not open ServletContext resource [/WEB-INF/spring-dispatcher-servlet.xml]

Más detalles a continuación:

Este es mi web.xml

/WEB-INF/spring-dispatcher-servlet.xml que no encuentra /WEB-INF/spring-dispatcher-servlet.xml pero no lo puse en web.xml , mi archivo de configuración es app-config.xml

Answer 1

Asegúrate de que tu bloque de plugin maven war en pom.xml incluya todos los archivos (especialmente los xml) mientras construyes la guerra. Pero no es necesario que incluya los archivos .java.

             <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.5</version>                
                <configuration>     
                      <webResources>
                        <resources>
                            <directory>WebContent</directory>
                            <includes>
                              <include>**/*.*</include><!--this line includes the xml files into the war, which will be found when it is exploded in server during deployment -->
                            </includes>
                            <excludes>
                               <exclude>*.java</exclude>
                            <excludes>
                        </resources>                         
                      </webResources>               
                  <webXml>WebContent/WEB-INF/web.xml</webXml>                                    
                </configuration>
            </plugin> 

Answer 2

Cita del documento de referencia de Spring :

Tras la inicialización de un DispatcherServlet, Spring MVC busca un archivo llamado [servlet-name] -servlet.xml en el directorio WEB-INF de su aplicación web y crea los beans definidos allí ...

Su servlet se llama spring-dispatcher , por lo que busca /WEB-INF/spring-dispatcher-servlet.xml . Necesita tener esta configuración de servlet y definir beans relacionados con la web (como controladores, resolución de vista, etc.). Consulte la documentación vinculada para obtener más información sobre la relación de los contextos de servlets con el contexto de la aplicación global (que es el app-config.xml en su caso).

Una cosa más, si no te gusta la convención de nomenclatura de servlet config xml, puedes especificar tu configuración explícitamente:

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

Answer 3

Encontré esta excepción en WebLogic, resulta que es un error en WebLogic. Por favor, mira aquí para más detalles: Excepción de Spring Boot: no se pudo abrir el recurso ServletContext [/WEB-INF/dispatcherServlet-servlet.xml]

Answer 4

Si obtiene este error con una configuración Java, generalmente se debe a que se olvida de pasar el contexto de la aplicación al constructor DispatcherServlet :

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet()); // <-- no constructor args!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

Solucionarlo agregando el contexto como el constructor arg:

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet(ctx)); // <-- hooray! Spring doesn''t look for XML files!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");
