I am using Spring MVC, Spring security and deploying in Apache Tomcat 1.7x. I notice that Web Application context is getting loaded twice. Please let me know what is wrong with my configuration.

I have referred below posts but could not identify the difference Why Spring Context is loaded twice?, Spring MVC web app: application context starts twice

INFO ContextLoader:273 - Root WebApplicationContext: initialization started

Below is my web.xml

<?xml version="1.0" encoding="UTF-8"?>

There are more than way to do this. The way that will work depends how servlet-context.xml are.

First, you can just remove <beans:import resource="servlet-context.xml" /> from your spring-security.xml.

Other way is remove this:

<!-- The definition of the Root Spring Container shared by all Servlets and 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 an import to spring-security.xml in servlet-context.xml.

A good practice is separate your configuration in multiple application contexts, import all in an applicationContext.xml and have a specific application context for the servlet context, something like 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 your 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>

  • thanks for your response. But removing either does not resolve bean dependencies and hence throws error. – ad-inf May 31 '15 at 20:29
  • @ad-inf if you remove the import from spring-security.xml, you can't resolve beans? How looks your servlet-context.xml? Improved the answer, see if now helps you. – Bruno Ribeiro Jun 02 '15 at 23:08
