Hi Daniil,
There is no simple way of accessing session in a TypeConverter. I've achieved
this by using Spring with a session bean. Unfortunetly, I've been forced to do
some hacking with Spring so it's context is saved in a static variable.
One you do this hack, simply have a TypeConverterFactory with:
public class SpringTypeConverterFactory extends DefaultTypeConverterFactory {
/**
* Add spring beans to converter.
*/
@Override
@SuppressWarnings("unchecked")
public TypeConverter getInstance(Class<? extends TypeConverter> clazz, Locale
locale) throws Exception {
TypeConverter converter = super.getInstance(clazz, locale);
SpringConfig.injectBeans(converter);
return converter;
}
}
And you can use @Autowired in any TypeConverter.
For your information here's my SpringConfig class:
public class SpringConfig implements ApplicationContextAware {
private static Logger logger = LoggerFactory.getLogger(SpringConfig.class);
/**
* Spring ApplicationContext.
*/
private static ApplicationContext applicationContext;
/**
* Inject Spring dependence into bean.
* If bean was created by cglib, this method may not be able to set beans
correctly.
* @param bean Object.
*/
public static void injectBeans(Object bean) {
AutowireCapableBeanFactory beanFactory =
applicationContext.getAutowireCapableBeanFactory();
beanFactory.autowireBeanProperties(bean,
AutowireCapableBeanFactory.AUTOWIRE_NO, false);
beanFactory.initializeBean(bean, bean.getClass().getSimpleName());
}
public void setApplicationContext(ApplicationContext context) {
applicationContext = context;
}
// Called as detroy-method.
public void close() {
applicationContext = null;
}
}

Subject: [Stripes-users] access session from a TypeConverter
Here's a good one. I have a TypeConverter that needs to access some variables
for the current session. So far, I haven't found a way of doing that via
library. I could be missing something. Can someone point me in the right
direction?
