澤西島給404-沒有發現有效的服務

Question

我面臨一個奇怪的問題，我的澤西島休息Servlet，我使用澤西島1.17.1與配置波紋管，但是，當我嘗試訪問我的休息服務，它只給我一個404 - 未找到錯誤。

奇怪的是該日誌：接受根資源類： 「/」，但我不要求對「/」我請求在「/ R/...」

com.sun.jersey.config.property.resourceConfigClass。

和日誌表明服務是否正確裝入：

Root resource classes found: 
    class com.xxx.restful.SearchRESTService 

在這裏你可以看到正在運行的服務：

2 < X-Jersey-Trace-001: match path "/" -> "/application\.wadl(/.*)?", "/request(/.*)?", "/search(/.*)?" 

的web.xml

<context-param> 
    <param-name>context-root</param-name> 
    <param-value>root</param-value>

休息服務：

@Path("/search") 
public class SearchRESTService { 

    @GET 
    @Path("/related") 
    @Produces({ MediaType.APPLICATION_JSON }) 
    public Response getRelatedSearch(@QueryParam("query") String query) { 
     List<String> result = ...; 
     return Response.ok(result).build(); 
    } 
}

我認爲你需要添加下面幾行你web.xml。假設你的球衣類是在包com.example，那麼你就需要添加：

<init-param> 
    <param-name>com.sun.jersey.config.property.packages</param-name> 
    <param-value>com.example</param-value> 
</init-param> 

這將確保你的根資源類可以通過新澤西州被發現。
