如何在guice模块中注入servlet上下文？

如何解决如何在guice模块中注入servlet上下文？

很抱歉输入错误的标题...
免责声明：在网络应用程序方面没有太多经验，主要是使用dropwizard。

所以我一直在尝试在Java Web应用程序中使用guice

我在servlet /资源文件中有servletContext，但是我需要在guice模块中注入，如何在guice模块中注入servlet上下文？

下面是参考代码，不胜感激！

CacheService

public interface CacheService {
    public abstract String hello();
}

CacheServiceImpl

public class CacheServiceImpl implements CacheService {
JedisPool jedisPool = null;

@Context
private ServletContext servletContext;

@Provides
public String hello() {
    log.info("CacheServiceImpl servletContext {}",servletContext); //  this is null
    return "hello world";
}


@Provides
public Jedis getJedisConnection() {
    HostAndPort redisServer = HostAndPortUtil.getRedisServers().get(0);
    if (jedisPool == null)
        jedisPool = new JedisPool(getJedisPoolConfig(),redisServer.getHost(),redisServer.getPort(),Protocol.DEFAULT_TIMEOUT,servletContext.getInitParameter("REDIS_PSWD")); // sample example of servletContext requirement,there are other functions in this module which need context 
    return jedisPool.getResource();
}

}

CacheModule

public class CacheModule implements Module{

    public void configure(final Binder binder) {
        binder.bind(ResourceServlet.class);
        binder.bind(CacheService.class).to(CacheServiceImpl.class);
    }
}

ResourceServlet

@Slf4j
@Path("/")
@Singleton
public class ResourceServlet {

    @Context
    private ServletContext servletContext;

    @Inject
    public ResourceServlet(CacheService storageModule) throws JAXBException {
          log.info("base {}",storageModule.hello());
    }

    @GET
    @Path("/test")
    @Produces({MediaType.APPLICATION_JSON})
    public Product abc() {
        log.info("servletContext {}",servletContext); // this is not null but how do i pass it on to module?
        
    }
}
