Injecting a service in spring boot filter
Have a filter where a service is autowired.
I am injecting the service as constructor argument - from the config where filter is registered.
MyFilter implements filter {
private final ServiceToBeInjected serviceToBeInjected;
public MyFilter(ServiceToBeInjected serviceToBeInjected) {
this.serviceToBeInjected = serviceToBeInjected;
}
}
public class ConfigClass {
private final ServiceToBeInjected serviceToBeInjected;
@Autowired
public ConfigClass(ServiceToBeInjected serviceToBeInjected) {
this.serviceToBeInjected = serviceToBeInjected;
}
@Bean
public FilterRegistrationBean<MyFilter> filterRegistrationBean() {
final FilterRegistrationBean<MyFilter> filterRegBean = new FilterRegistrationBean<>();
filterRegBean.setFilter(new MyFilter(serviceToBeInjected));
filterRegBean.addUrlPatterns(");
return filterRegBean;
}
}
I kind of felt autowiring from config might not be good.
Is there any other better way ?

Please learn correct indentation. It was unreadable. Fixed it for you this time.

If MyFilter is only constructed once then it can be a component, which means it will be autowired implicitly.
@Component
MyFilter implements Filter {
private final ServiceToBeInjected;
// Autowired implicitly
public MyFilter(ServiceToBeInjected serviceToBeInjected) {
this.serviceToBeInjected = serviceToBeInjected;
}
}
Your bean can then take the filter as a method parameter
public class ConfigClass {
@Bean
public FilterRegistrationBean<MyFilter> foo(final MyFilter filter) {
final FilterRegistrationBean<MyFilter> bean = new FilterRegistrationBean<>();
bean.setFilter(filter);
bean.addUrlPatterns(");
return bean;
}
}
If MyFilter needs to be constructed more than once then what you've done is fine.
