春季+球衣+篩選+ @Provider

[英]Spring + Jersey + Filter + @Provider

問題描述

我嘗試僅使用注釋使用Spring配置Jersey。 我用@Path和@Component注釋對資源類進行注釋。 一切正常，直到我嘗試配置一些過濾器。 我創建了這樣的過濾器： 

@Service
@Provider @PreMatching
public class MyFilter implements ContainerRequestFilter {

    public MyFilter() {
        System.out.println("MyFilter()");
    }

    @Override
    public ContainerRequest filter(ContainerRequest request) {
        System.out.println("filtered");
        return request;
    }
}

好像在調用bean時就創建了bean並在Jersey中注冊了過濾器，就像我看到的那樣： 

INFO: Registering Spring bean, myFilter, of type pl.igt.filter.MyFilter as provider class

在有關資源組件注冊的信息旁邊。 我可以調用我的資源，它可以正常工作，但實際上從未使用過過濾器。

對於那些到這里來並沒有解決方案感到沮喪的人，以下是我最終得到的解決方案：

對於：

  • 春季v3.2.9
  • 球衣v1.18.1

過濾器實施 

package com.acme.sample.rest;
public class MyFilter implements ContainerRequestFilter {

    @Override
    public ContainerRequest filter(ContainerRequest request) {
        System.out.println("filtered");
        return request;
    }
}
