Getting java.io.NotSerializableException with a spring service when stopping tomcat

Question

i am using spring 3 with JSF 2 and i replaced JSF managed beans with spring beans, by adding on top of bean:

@Component(\"mybean\")
@Scope(\"session\")
         


        

Answer 1

I had to use readObject() + static ApplicationContext hack to solve the issue:

@Component
@Scope(value = SCOPE_SESSION, proxyMode = ScopedProxyMode.TARGET_CLASS)
public class FlashMessages implements Serializable {    

    @Autowired
    transient private SomeBean someBean;

    private void readObject(ObjectInputStream ois) throws ClassNotFoundException, IOException {
        ois.defaultReadObject();
        // restore someBean field on deserialization
        SpringUtils.getContext().getAutowireCapableBeanFactory().autowireBean(this);
    }

}

@Component
public class SpringUtils implements ApplicationContextAware {

    static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringUtils.applicationContext = applicationContext;
    }

    public static ApplicationContext getContext() {
        return applicationContext;
    }

}
