Spring request scope bean

问题

How can I set up a bean which will created once per request.

I Tried to do like this :

   @Component
   @Scope(value = "request")
   public class TestBean {
        @PostConstruct
        public void init() {
             System.out.println("start request");
        }

        @PreDestroy
        public void onDestroy() {
             System.out.println("ends request");
        }
   }

Thanks.

Try this @Scope(value="request", proxyMode= ScopedProxyMode.TARGET_CLASS)

You can set your bean to request scope by xml configuration as

 <bean id="testBean" class="com.test.TestBean" scope="request">
    <aop:scoped-proxy/>
  </bean>

Tag aop:scoped-proxy will be used to inject your bean using proxy. This is xml based way to set your bean to request scope.
