Error while applying session scope to a bean in spring


I tried to change the scope of a bean using @Scope annotation. That bean is actually working as MessageSource and used for internationalization purpose.

The schema in mvc-dispacher-servlet.xml is as follows:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
     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/aop 
        http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

Exception described in console is as follows:

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Cannot locate BeanDefinitionParser for element [scoped-proxy]


Solution

  • Ok. If its a normal bean then most likely you are just missing the xml parser for the scope tag. To be able to use scoped proxies you need to register aop:scoped-proxy.

    There is a similar question on SO: Accessing a session-scoped bean inside a controller

    Which results in:

    Else you should easily find some tutorials on this topic through google.
