java - How to avoid "Root WebApplicationContext: initialization started" loading twice? -

i using spring mvc, spring security , deploying in apache tomcat 1.7x. notice web application context getting loaded twice. please let me know wrong configuration.

i have referred below posts not identify difference why spring context loaded twice?, spring mvc web app: application context starts twice

info contextloader:273 - root webapplicationcontext: initialization started

below web.xml

<?xml version="1.0" encoding="utf-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">      <!-- definition of root spring container shared servlets , filters -->     <context-param>         <param-name>contextconfiglocation</param-name>         <param-value>web-inf/spring/appservlet/spring-security.xml</param-value>     </context-param>      <!-- creates spring container shared servlet , filters -->     <listener>         <listener-class>org.springframework.web.context.contextloaderlistener</listener-class>     </listener>     <listener>         <listener-class>org.springframework.security.web.session.httpsessioneventpublisher</listener-class>     </listener>     <session-config>         <session-timeout>5</session-timeout>     </session-config>      <!-- spring security filter -->     <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>      <!-- processes application requests -->     <servlet>         <servlet-name>appservlet</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>      <servlet-mapping>         <servlet-name>appservlet</servlet-name>         <url-pattern>/</url-pattern>     </servlet-mapping> </web-app> 

my spring-security.xml

<?xml version="1.0" encoding="utf-8"?> <beans:beans xmlns="http://www.springframework.org/schema/security"     xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd             http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">      <beans:bean id="rolevoter"         class="org.springframework.security.access.vote.rolevoter">         <beans:property name="roleprefix" value=""></beans:property>     </beans:bean>     <beans:import resource="servlet-context.xml" />      <beans:bean id="accessdecisionmanager"         class="org.springframework.security.access.vote.affirmativebased">         <beans:constructor-arg name="decisionvoters"             ref="rolevoter" />     </beans:bean>      <http authentication-manager-ref="login-service"         access-decision-manager-ref="accessdecisionmanager"> ....     </http>        <beans:bean id="userloginservice" class="my.test.service.impl.userloginservice">         <beans:property name="userprofileservice" ref="userprofileservice" />     </beans:bean>         <!-- login message -->     <beans:bean id="messagesource"         class="org.springframework.context.support.resourcebundlemessagesource">         <beans:property name="basenames">             <beans:list>                 <beans:value>mymessages</beans:value>             </beans:list>         </beans:property>     </beans:bean>   </beans:beans> 

there more way this. way work depends how servlet-context.xml are.

first, can remove <beans:import resource="servlet-context.xml" /> spring-security.xml.

other way remove this:

<!-- definition of root spring container shared servlets , filters --> <context-param>     <param-name>contextconfiglocation</param-name>     <param-value>web-inf/spring/appservlet/spring-security.xml</param-value> </context-param> 

and this:

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

and include import spring-security.xml in servlet-context.xml.

a practice separate configuration in multiple application contexts, import in applicationcontext.xml , have specific application context servlet context, this:

applicationcontext.xml:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:context="http://www.springframework.org/schema/context"     xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">      <context:component-scan base-package="com.package" />      <import resource="applicationcontext-security.xml"/>     <import resource="applicationcontext-data.xml"/>  </beans> 

applicationcontext-servlet.xml:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:context="http://www.springframework.org/schema/context"     xmlns:p="http://www.springframework.org/schema/p"     xmlns:mvc="http://www.springframework.org/schema/mvc"     xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd         http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd         http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd">      <mvc:annotation-driven />      <bean id="viewresolver" class="org.springframework.web.servlet.view.internalresourceviewresolver"         p:prefix="/web-inf/views/" p:suffix=".jsp" />      <bean class="org.springframework.web.servlet.handler.simplemappingexceptionresolver" p:order="3" p:defaulterrorview="error" />  </beans> 

and in web.xml:

<!-- spring servlet --> <servlet>     <servlet-name>springdispatcherservlet</servlet-name>     <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>     <init-param>         <param-name>contextconfiglocation</param-name>         <param-value>web-inf/applicationcontext-servlet.xml</param-value>     </init-param>     <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping>     <servlet-name>springdispatcherservlet</servlet-name>     <url-pattern>/</url-pattern> </servlet-mapping>  <listener>     <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <context-param>     <param-name>contextconfiglocation</param-name>     <param-value>classpath:meta-inf/applicationcontext.xml</param-value> </context-param>
