CORS Filter找不到 - 球衣

我一直在努力解決這個問題很長一段時間了。它突然開始，我不知道如何解決它或我做錯了什麼。我已經堆疊了很長時間，並沒有得到任何地方。我試過here，here和許多其他的鏈接。當這個開發環境成立時，我沒有在這裏工作，以前從來沒有真正與澤西一起工作。CORS Filter找不到 - 球衣

誰能告訴我爲什麼我得到：

這是我的web.xml：

<servlet> 
     <servlet-name>Jersey REST Service</servlet-name> 
     <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> 
     <init-param> 
      <param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name> 
      <param-value>PACKAGE_PATH.ResponseCorsFilter</param-value> 
     </init-param>  
     <init-param> 
      <param-name>com.sun.jersey.config.property.packages</param-name> 
      <param-value>PACKAGE_PATH.controller, 
         PACKAGE_PATH.supin.controller, 
         PACKAGE_PATH.rth.controller, 
         PACKAGE_PATH.rtp.pgto.controller, 
         PACKAGE_PATH.dir.controller.bgt, 
         PACKAGE_PATH.kpi.dir.controller.pa</param-value> 
     </init-param>  
     <load-on-startup>1</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>Jersey REST Service</servlet-name> 
     <url-pattern>/rest/*</url-pattern> 
    </servlet-mapping>

這是我ResponseCorsFilter.java：

public class ResponseCorsFilter implements ContainerResponseFilter { 

@Override 
public ContainerResponse filter(ContainerRequest req, ContainerResponse contResp) { 
    ResponseBuilder resp = Response.fromResponse(contResp.getResponse()); 
    resp.header("Access-Control-Allow-Origin", "*") 
      .header("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT, OPTIONS, HEAD"); 

    String reqHead = req.getHeaderValue("Access-Control-Request-Headers"); 

    if(null != reqHead && !reqHead.equals("")){ 
     resp.header("Access-Control-Allow-Headers", reqHead); 
    } 

    contResp.setResponse(resp.build()); 

    return contResp; 
} 

}

這是控制器之一。我通過使用http://localhost:8081/CSI/rest/chart/pa/01012013/01012014/getPA

@Path("chart/pa") 
public class PAController { 

@GET 
@Produces(MediaType.APPLICATION_JSON) 
@Path("/{firstParam}/{secondParam}/getPA") 
public Response GetPA(@PathParam("firstParam") String p1, 
      @PathParam("firstParam") String p2) throws Exception { 

...

我錯過了什麼嗎？

解決了它，並忘記發佈答案。

我從其他開發者導入WAR文件。起初，它運行良好。但是，突然間，它停了下來。我意識到我錯過了構建路徑上的Jersey文件。由於它工作了一段時間，我從來沒有想過它會開始這樣的行爲。

我使用Eclipse，所以這是很容易：

工程資源管理器 - >在項目上單擊右鍵 - >構建路徑 - >配置構建路徑

然後：

添加外部JAR

SIMPL就像那樣。
