如何从springSessionRepositoryFilter中排除资源？

Question

We are trying to convert a legacy project to a more modern one. It was a servlet based application with jsp's, and we are moving towards Spring. We serve jsp-s, and they include many static resources. We are using Redis as session store, and it's mapped like a filter:

<filter>
    <filter-name>springSessionRepositoryFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
    <filter-name>springSessionRepositoryFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

...

@Configuration
@EnableRedisHttpSession(maxInactiveIntervalInSeconds = SpringSessionConfig.MAX_INACTIVE_INTERVAL_IN_SECONDS)
@PropertySource(value = "classpath:redis.properties")
public class SpringSessionConfig { ... }

Static resources are spread in many different directories, and the problem is that, this filter runs for each and every resource, which is totally understandable.

Is there a smart way to exclude resources from this url pattern? Or some configuration for this RepositoryFilter?

The only solution I came up with, is to do a big refactor, and make proper namespaces for static resources, but right now, that's too much effort.

I also added resource handlers to Spring configuration, but it's ignored here.

我认为您可以扩展springSessionRepositoryFilter来实现自己的过滤器，然后在doFilterInternal方法中doFilterInternal排除资源，并配置springSessionRepositoryFilter bean手册而不是EnableRedisHttpSession批注，然后将过滤器bean名称配置为web.xml。
