SpringBoot how to set order of Filter without annotation

Question

I'm trying to insert (at first position) a simple custom Cors filter inside the spring filter chain.

If I do it like this

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CorsFilter implements Filter {

it works perfectly I can verify it by putting a breakpoint in Spring's ServletHandler.java where there the line

chain=getFilterChain(baseRequest, target, servlet_holder);

I was just wondering if I wish not to use @Componenent and @Order and instead defining the Filter bean the Application context. How can I set the order of the filters ?

Answer 1

See example: In your class ServletInitializer:

@Bean
 public FilterRegistrationBean requestLogFilter() {
        final FilterRegistrationBean reg = new FilterRegistrationBean(createRequestLogFilter());
        reg.addUrlPatterns("/*");
        reg.setOrder(1); //defines filter execution order
        return reg;
 }

 @Bean
 public RequestLogFilter createRequestLogFilter(){
        return new RequestLogFilter();
 }

the name of my filter is "requestLogFilter"

Warning: Don't use @Component annotation at the class Filter.
